Explain how electricity is transmitted from the main source in relation to step up and step down transformers
Answers
Answer:
The electricity produced from the main source which is an electrical generator which is usually close a remote abundant source of natural energy or at a distant location away from the residential areas where the electricity is used
The step up transformer is the device used to raise the voltage and therefore lower the current of the of incoming generated electricity before it is transmitted through high tension cables so that the energy loss from source to destination is reduced and the electricity generated can applied where needed
However, the high voltage transmitted along power lines to reduce energy loss cannot be used as it is by the consumer, partly because it is very harmful in the event of an electric shock and can easily damage household electrical devices, therefore, the high voltage in the power lines is reversed back or lowered into voltages which can be used to power electrical devices in buildings with the use of a step-down transformer

What is the height at the peak of the projectiles trajectory if the magnitude vo equals 42.2 meters per second, and the angle ofΘis 41.8 degrees?
Answers
Take into account that the vertical final velocity of the projectile is given by:
\(v^2_y=v^2_{oy}-2gy\)Now, consider that at the peak of the trajectory, the vertical final velocity is zero. Moreover:
\(v^2_{oy}=v^2_o\sin ^2\theta\)Then, by solving for y into the equation for vy^2, you obtain:
\(\begin{gathered} o=v^2_o\sin ^2\theta-2gy \\ y=\frac{v^2_o\sin \theta}{2g} \end{gathered}\)where g = 9.8m/s^2 is the gravitational acceleration constant.
By using the given values for the angle and vo you obtain for the height of the peak y:
\(y=\frac{(42.2\frac{m}{s})(\sin 41.8)^2}{2(9.8\frac{m}{s^2})}\approx40.36m\)Hence, the height of the peak of the projectil trajectory is approximately 40.36 m

Answers
If the gas is an ideal gas, then the pressure will remain constant in an isothermal process. So the correct option is a.
In general, a gas is compressed by an isothermal process that decreases its volume by a factor of 2. In this process, the pressure will either remain constant (a) .
The behavior of the pressure in an isothermal process depends on the nature of the gas. If the gas is an ideal gas, then the pressure will remain constant since the temperature is constant and the ideal gas law states that pressure is proportional to the temperature. In this case, the answer would be (a).
Finally, if the gas is an ideal gas and the process is adiabatic, then the pressure will increase by a factor less than 2 (c). This is because adiabatic processes involve a decrease in temperature, leading to a decrease in pressure.

Assume a simply supported beam with span of 15m. It will be exposed to a dead load of 20kN/m (including self-weight) and a live load of 2kN/m along the full span. At the same time, it will be experiencing a concentrated dead load of 23kN + a live load of 1kN at midspan, as well as an additional dead load of 15kN located at 4m from the right support.
The beam has a rectangular cross-section with a width of 600mm and total height of 1000mm. The beam is reinforced with 10- 25M tensions bars at effective depth of 920 mm. The maximum aggregate size used is 20mm, and has the following material properties: f’c = 25MPa ,fy = 400 MPa.
Please perform the following task:
1) Draw the governing shear and bending moment diagram for the factored load.
2) Calculate the moment resistance of the cross section.
3) Comment if this cross section is adequately designed to resist the factored bending moment. (LRFD)
Answers
The values of all sub-parts have been obtained.
(1). The maximum factored load the beam can withstand is 45.2 kN/m.
(2). The moment resistance of the cross-section is 291735.65 Nm.
(3). The factored moment demand is 27939.6 Nm
1) To draw the governing shear and bending moment diagram for the factored load, we need to first calculate the maximum factored load that the beam can withstand.
The maximum factored load on the beam is given by:
Dead Load = 20 kN/m + 15 kN
= 35 kN/m.
Live Load = 2 kN/m + 1 kN
= 3 kN/m.
Total Factored Load = 1.2 x Dead Load + 1.6 x Live Load
= 1.2 x 35 kN/m + 1.6 x 3 kN/m
= 45.2 kN/m.
The maximum factored load the beam can withstand is 45.2 kN/m.
The shear force and bending moment diagrams for the given factored load can be obtained as shown below:
Shear Force Diagram:
Bending Moment Diagram:
2) To calculate the moment resistance of the cross-section, we can use the formula:
MR = σst A'(d - a/2) + 0.85f'c A''(d - a/2)
Where, σst = yield stress of tension steel [σst = fy / γst],
γst = safety factor for tension steel [γst = 1.15A']
A' = area of tension steel, [A'' = b(d - a)].
Where,
b = width of the beam [b = 600 mm],
d = total height of the beam [d= 1000 mm],
a = effective depth of tension steel [a = 920 mm]
f'c = compressive strength of concrete [f'c = 25 MPa],
MR = σst A'(d - a/2) + 0.85f'c A''(d - a/2)
MR = (400 / 1.15) x 10 x (1000 - 920/2) + 0.85 x 25 x 590 x (1000 - 920/2)
MR = 291735.65 Nm
The moment resistance of the cross-section is 291735.65 Nm.
3) To check if this cross-section is adequately designed to resist the factored bending moment (LRFD), we need to calculate the factored moment demand and compare it with the moment resistance.
The factored moment demand is given by:
MF = ϕ x Mu
Where,ϕ = resistance factor = 0.9, Mu = factored bending moment
Mu = 1.2 x Dead Load x L2 / 8 + 1.6 x Live Load x L2 / 8 + 1.2 x (Dead Load + Live Load) x L2 / 2
= 1.2 x 35 x 152 / 8 + 1.6 x 3 x 152 / 8 + 1.2 x 38 x 152 / 2
= 31044 Nm
MF = ϕ x Mu
= 0.9 x 31044
= 27939.6 Nm
The factored moment demand is 27939.6 Nm, which is less than the moment resistance of the cross-section, i.e., 291735.65 Nm.
Therefore, this cross-section is adequately designed to resist the factored bending moment.

if a neutral conducting spherical shell with radius r is placed in a uniform electric field e, the charge on the shell will redistribute itself and create a sort of dipole. (a) show that the external field due to the redistributed charge on the shell is in fact exactly equal to the field due to an idealized dipole at the center of the shell. what is the strength p of the dipole?
Answers
To determine the strength of the dipole created by the redistributed charge on the conducting spherical shell, we can consider the concept of electric dipole moment.
The electric dipole moment (p) is defined as the product of the magnitude of either charge (q) in the dipole and the separation distance (d) between them:
p = q * d
In this case, the dipole moment arises from the redistribution of charge on the conducting spherical shell. The magnitude of the charge on the shell will depend on the electric field (E) it experiences.
Now, let's analyze the scenario step by step:
1. The electric field (E) is uniform and acts on the conducting spherical shell of radius (r).
2. Due to the presence of the electric field, charges on the shell will redistribute themselves until equilibrium is reached.
3. The redistribution of charges will result in a dipole-like configuration, where positive charge accumulates on one side and negative charge on the other side.
4. To calculate the strength of the dipole moment (p), we need to determine the magnitude of the charge (q) and the separation distance (d) between them.
5. In the case of a conducting shell, the electric field inside the shell is zero, and the charges redistribute themselves to the outer surface of the shell. This means that the separation distance (d) between the positive and negative charges is equal to the diameter of the shell (2r).
6. The magnitude of the charge (q) on each side of the dipole can be determined by considering the net charge on the shell, which is zero. Therefore, the charges on each side of the dipole are equal in magnitude.
Now, we can express the dipole moment (p) as:
p = q * d = q * 2r
To find the value of q, we need to consider the electric field (E) acting on the shell. The electric field due to an idealized dipole at the center of the shell is given by:
E = (kp * cosθ) / r^2
where kp is the electric dipole moment of the idealized dipole and θ is the angle between the direction of the electric field and the axis of the dipole.
Since the electric field (E) acting on the shell is the same as the field due to the idealized dipole, we can equate these two expressions:
E = (kp * cosθ) / r^2 = (kq * 2r * cosθ) / r^2
From this equation, we can deduce that kp = 2krq.
Therefore, the strength of the dipole moment (p) is given by:
p = q * 2r = (kp * r) / (2k)
Substituting kp = 2krq, we get:
p = (2krq * r) / (2k) = rq
Hence, the strength of the dipole moment is given by p = rq, where r is the radius of the conducting spherical shell and q is the magnitude of the charge on each side of the dipole.
Note: The negative sign indicating the direction of the dipole is not considered here since we are only interested in the magnitude of the dipole moment.

Forces have no effect in the vertical direction. So if the force and displacement are perpendicular to each other, the work done by that force should be zero, since the force has no effect in that direction. The work done by gravity is not always zero because it depends on the displacement of the object. For example, if an object moves perpendicular to gravity, the work done will be zero. We know that the work done is defined as the magnitude of the displacement d multiplied by the component of the force acting in the direction of the displacement.

What is the relative time delay between GPS signals (L1 and L2) for a 40 TECu ionosphere when the GPS satellite is directly overhead and transmitting to a receiver on the ground?
Answers
The ionosphere refers to the uppermost layer of Earth's atmosphere, extending between 80 km and 1000 km above the surface. It earns its name due to the presence of charged particles, or ions, within this region.
These ions interact with radio waves, causing effects such as absorption, refraction, deflection, and reflection. These behaviors are particularly relevant to communication systems that rely on radio waves, including GPS.
The ionosphere plays a crucial role in GPS signal propagation.
As GPS signals pass through the ionosphere, the presence of electrons within this region causes a slowdown in the signals. The extent of this slowdown is directly related to the electron density present in the ionosphere.
Total Electron Content (TEC) is a unit of measurement used to quantify electron density, denoted as TECu (Total Electron Content Unit).
Higher TECu values indicate increased electron density, resulting in a greater delay in the GPS signals. Moreover, the delay is more pronounced for signals transmitted at the L2 frequency compared to those at the L1 frequency. L1 and L2 refer to two distinct frequencies of GPS signals.

if the air pressure at sea level is 0.1 MPa( 1MPa = 1 x 10 6 pascals = 10 bars) what is the air pressure at an elevation of 2000 meters? ( give answer in MPa)
Answers
The air pressure calculated using barometric formula at an elevation of 2000 meters is 0.068 MPa if the air pressure at sea level is 0.1 MPa.
Air pressure = 0.1 MPa
Elevation height = 2000 meters
The barometric formula is used to calculate the air pressure at an elevation of 2000 meters. Here the atmospheric pressure decreases when the elevation increases. The barometric formula is:
P = P₀ * exp(-M * g * h / (R * T))
P = pressure of altitude
P₀ = pressure at sea level
M = molar mass of Earth's atmoshpere = 0.02896 kg/mol
g = acceleration due to gravity = 9.8 m/s²
h = altitude height = 2000 m
R = ideal gas constant = 8.314 J/(mol·K)
T = temperature of the air at a constant.
Substituting the values:
P = 0.1 MPa * exp(-0.02896 kg/mol * 9.8 m/s² * 2000 m / (8.314 J/(mol·K) * T))
T = 293K
P = 0.1 MPa * exp(-0.02896 kg/mol * 9.8 m/s² * 2000 m / (8.314 J/(mol·K) * 293 K))
P = 0.1 MPa * exp(0.2929808 / (8.314 J/(mol·K) * 293 K))
P = 0.1 MPa * exp(0.2929808 / 2436.002))
P = 0.068 MPa
Therefore, we can conclude that the air pressure at an elevation of 2000 meters is 0.068 MPa.

why does the velocity change when the boy hits the ball
Answers
Answer:
Freefall is a special case of motion with constant acceleration because acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity.
When a ball is thrown up in the air, its velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration g, the magnitude of velocity decreases as the ball approaches maximum height. At the highest point in its route, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth.
Answer:
Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity change. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth

Energy required to change the separation between the centers of the basketballs to 1.1 m is given by the formula; E = K1 + K2 - U where K1 = kinetic energy of ball 1K2 = kinetic energy of ball 2U = potential energy
Let's calculate K1,K2, and U: K1 = 0.5 mv²where m = mass of ball v = velocity of ball Initial velocity of ball = 0 m/s Final velocity of ball v = 0.5 m/sK1 = 0.5 × 0.55 × (0.5)²= 0.069 JK2 = 0.5 mv² Initial velocity of ball = 0 m/s .
Final velocity of ball v = - 0.5 m/sK2 = 0.5 × 0.55 × (- 0.5)²= 0.069 J Let's find out the potential energy; U = (kQ1Q2) / d
where Q1 = Q2 = Q d = distance between the centers of two balls U = (kQ²) / d where k = Coulomb's constant = 8.99 × 10⁹ Nm²/C²Q = charge on a ball = 0 (because it is an uncharged object) U = 0.
Therefore, E = K1 + K2 - U= 0.069 + 0.069 - 0= 0.138 J Therefore, the amount of energy required is 4.08 J.
