The speed of the rocket would be  1,607.6 m/s.

Let's start by calculating the mass of the rocket at any given time t:

m(t) = 5,000 kg - (200 kg/s) t

The net force on the rocket is given by:

F = (u - v(t)) dm/dt

where v(t) is the velocity of the rocket at time t, and u is the velocity of the ejected gas relative to the rocket.

At the moment when the rocket reaches the ejection velocity of the gas, the net force is zero. So we can set F to zero and solve for v(t):

0 = (2,000 kg/s - v(t)) (200 kg/s)

v(t) = 2,000 kg/s

Now we can use Newton's second law of motion to relate the net force on the rocket to its acceleration:

F = m(t) a(t)

a(t) = F / m(t)

At the moment when the rocket reaches the ejection velocity of the gas, the acceleration of the rocket is:

a(t) = (2,000 kg/s) / (5,000 kg - (200 kg/s) t)

We can integrate this expression with respect to time to find the velocity of the rocket as a function of time:

v(t) = (2,000 m/s) ln(5,000 kg / (5,000 kg - (200 kg/s) t)) + C

where C is a constant of integration that we can determine from the initial condition v(0) = 0:

0 = (2,000 m/s) ln(5,000 kg / 5,000 kg) + C

C = 0

Therefore, the velocity of the rocket as a function of time is:

v(t) = (2,000 m/s) ln(5,000 kg / (5,000 kg - (200 kg/s) t))

We can now find the velocity of the rocket after 20 seconds:

v(20) = (2,000 m/s) ln(5,000 kg / (5,000 kg - (200 kg/s) (20 s)))

v(20) ≈ 1,607.6 m/s

So the speed of the rocket after 20 seconds of launching is approximately 1,607.6 m/s.

Explanation:

(a)

F = (GM1M2)/r²

F = (6.7 X 10^-11 x 30.3 x 40.17)/0.5²

F = 326.197 x 10^-⁹N

(b)

F =750N

G = 6.7 x 10^-11

M1 = 2050kg

r = 70.3m

M2 = ?

F = (GM1M2)/r²

F x r² = GM1M2

(F x r²)/GM1 = M2

M2 = (750 x 70.3²)/(6.7 x 10^-11 x 2050)

M2 = 26.99kg

a) Z = 58.0 Ω - j66.35 Ω ;  b) Imax = 0.515 A  ; c) i = 0.515 sin(200πt + 42.5°) ; d) i = 0.515 sin(200πt + 0.741 rad)  ; e)  If the inductance of circuit is 0.0969 H, then current will lag the voltage by same angle as in part (d).  ;f) |Z| = 60.

Measure of the opposition that electrical circuit presents to the flow of alternating current is called impedance.

(a) Impedance (Z) of the circuit is : Z = R + j(XL - XC)

Inductive reactance and capacitive reactance are : XL = 2πfL

XC = 1/(2πfC)

XL = 2π(100 Hz)(150 mH) = 94.25 Ω

XC = 1/(2π(100 Hz)(99.0 µF)) = 160.6 Ω

Therefore,  impedance of the circuit is: Z = 58.0 Ω + j(94.25 Ω - 160.6 Ω) = 58.0 Ω - j66.35 Ω

(b) Maximum current (Imax) in the circuit is : Imax = Δv / |Z|

Δv is amplitude of the voltage

|Z| = √((58.0 Ω)² + (-66.35 Ω)²) = 87.4 Ω

Therefore, maximum current in the circuit is: Imax = (45.0 V) / (87.4 Ω) = 0.515 A

(c) The phase angle (θ) between the voltage and current is : tan(θ) = (XL - XC) / R

tan(θ) = (94.25 Ω - 160.6 Ω) / 58.0 Ω = -0.959

Therefore, phase angle is: θ = -42.5°

Equation for the current is: i = Imax sin(ωt - θ)

ω is angular frequency in radians per second. Angular frequency is : ω = 2πf = 2π(100 Hz) = 200π rad/s

i = 0.515 sin(200πt + 42.5°)

(d) Phase angle in radians is: θ = -42.5° = -0.741 rad

i = 0.515 sin(200πt + 0.741 rad)

(e) The condition for the current to lag the voltage by the same angle as in part (d) is: ωL - 1/(ωC) = tan(θ)R

L = (tan(θ)R + 1/(ωC)) / ω

L = (tan(-42.5°)(58.0 Ω) + 1/(2π(100 Hz)(99.0 µF))) / (2π(100 Hz))

L = 0.0969 H

Therefore, if the inductance of circuit is 0.0969 H, the current will lag the voltage by the same angle as in part (d).

(f) The maximum current in the circuit is given by the same formula as in part (b), with the impedance |Z| calculated using the inductance found in part (e).  |Z| = √((58.0 Ω)² + (-18.99 Ω)²) = 60.

For this exercise we must use the condition for interference and diffraction so that these phenomena are relevant the wavelength must be comparable to the gap spacing

                λ> = a

Lam when the spacing is much greater than the wavelength, the description of geometric optics is more and more exact

let's analyze each situation

a) let's find the wavelength

                v = λ f

                λ= v / f

                λ= 343/1000

                λ = 0.343 m

                 0.343 << 1m

therefore the description of the geometric optics of

         a = 8 mm 10⁻³

longitudinal is much less therefore the geometric optics is correct

c) luz azul lam = 450 nm = 450 10⁻⁹ m = 4.5 10⁻⁷ m

again the wavelength is much less than the diameter of the pupil, for which the description with the optics is generally sufficient

d) a radio A transmits up to a maximum of f = 1400 Khz = 1,400 10⁶ Hz

let's find the wavelength

          c = λf

          λ = c / f

           λ= 3 108 / 1,400 106

          λ= 2.14 102 m

in this case the wavelength is greater than the width of the gate, so the description of diffraction should be used to explain the phenomenon

Answer:

Carbon dioxide and water vapour

Explanation:

So the products of a combustion reaction are primarily:

carbon dioxide + water vapour, however other gases such as nitrogen, methane, and sulphur dioxide are also produced in smaller concentrations.

Carbon dioxide and water vapour are the main byproducts

Answer:

Carbon dioxide

Explanation:

The major byproduct of fossil fuel combustion is carbon dioxide. When fossil fuels such as coal, oil, and natural gas are burned, they release carbon dioxide into the atmosphere. This is because fossil fuels are made up of hydrocarbons, which are compounds made up of carbon and hydrogen. When these compounds are burned, they react with oxygen in the air to produce carbon dioxide \(\rm (CO_2)\) and water vapor \(\rm (H_2O)\).

Methane is also produced during fossil fuel combustion, but in smaller amounts compared to carbon dioxide. Sulfuric acid is not a byproduct of fossil fuel combustion, but rather a product of the reaction between sulfur dioxide \(\rm (SO_2)\) and water vapor in the atmosphere. While water vapor is also produced during fossil fuel combustion, it is not considered a major byproduct, as it is a natural component of the air and atmosphere.

Answer:

The total number of Cl atoms in 150mL of liquid CCl4 is 3.73*10²⁴.

Explanation:

First you must determine the mass of CCL4 present in 150mL of CCl4. Density is a quantity that allows us to measure the amount of mass in a certain volume of a substance, whose expression for its calculation is the quotient between the mass of a body and the volume it occupies:

\(density=\frac{mass}{volume}\)

In this case, the density value of d = 1.589 g/mL. Then, being the volume equal to 150 mL, the value of the mass can be calculated as:

mass= density*volume

mass=1.589 g/mL * 150 mL

mass= 238.35 g

Now, being the molar mass of CCl4 154 g/mol, the number of moles that 238.35 g represents is calculated as:

\(moles=\frac{238.35 g}{154 \frac{g}{mol} }\)

moles= 1.55

1 mole of the compound CCl4 contains 4 moles of Cl. Then, using a simple rule of three, it is possible to calculate the number of moles of Cl that 1.55 moles of CCl4 contain:

\(moles of Cl=\frac{1.55 moles of CCl_{4} *4 moles of Cl}{1 mole of CCl_{4} }\)

moles of Cl= 6.2

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number applies to any substance.  In this case it can be applied as follows: if 1 mole of Cl contains 6.023*10²³ atoms, 6.2 moles of Cl how many atoms does it contain?

\(atoms of Cl=\frac{6.2 moles*6.023*10^{23} atoms}{1 mole}\)

atoms of Cl= 3.73*10²⁴

The total number of Cl atoms in 150mL of liquid CCl4 is 3.73*10²⁴.

To increase force on the door

The magnetic force per unit length of the wire is (C) (0.49i - 0.51j - 1.37k) N/m.

To calculate the magnetic force per unit length of the wire, we can use the formula:

F = I * (L x B),

where F is the force, I is the current, L is the length vector of the wire, and B is the magnetic field.

Given:

Current, I = 3A

Length vector, L = √√3 * (i + j + k)

Magnetic field, B = 0.75i + 0.4k

Let's calculate the cross product of L and B:

L x B = | i j k |

|√√3 √√3 √√3|

|0.75 0 0.4|

To evaluate this cross product, we calculate the determinants:

(i) component: (√√3 * 0 - √√3 * 0.4) = -0.4√√3

(j) component: (-√√3 * 0.75 - √√3 * 0) = -0.75√√3

(k) component: (√√3 * 0.75 - √√3 * 0) = 0.75√√3

Now, multiply the cross product by the current:

F = 3A * (-0.4√√3i - 0.75√√3j + 0.75√√3k)

Simplifying this expression gives:

F = (-1.2√√3i - 2.25√√3j + 2.25√√3k) N

Therefore, the magnetic force per unit length of the wire is approximately (-1.2√√3i - 2.25√√3j + 2.25√√3k) N/m.

It would require 28618.56 J of heat to raise the temperature of 90 g of water from 12°C to 88°C.

Given that:

Mass of water m = 90g

Initial temperature = 12°C

Final temperature = 88°C,

The amount of heat required to raise the temperature of a substance is given by:

Q = mCΔT

Where Q is the amount of heat, m is the mass of the substance, C is the specific heat capacity of the substance, and ΔT is the change in temperature.

Note that: the specific heat capacity of water is 4.184 J/g°C.

So, for raising the temperature of 90 g of water from 12°C to 88°C, we have:

Q = mCΔT

Q = (90 g) × (4.184 J/g°C) × (88°C - 12°C)

Q = (90 g) × (4.184 J/g°C) × (76°C)

Effects of Electric Current:

Electric current is the flow of electric charges in a conductor. When a current passes through a conductor, it produces several effects, some of which include:

1. Heating effect: The heating effect of electric current occurs when the current passes through a conductor, and the resistance of the conductor converts some of the electrical energy into heat. This effect is utilized in electric heaters, electric stoves, and incandescent light bulbs.

2. Magnetic effect: When an electric current passes through a conductor, it produces a magnetic field around the conductor. This effect is utilized in devices like motors and generators.

3. Chemical effect: Electric current can also cause chemical reactions to occur. This effect is utilized in batteries and electrolysis.

4. Electric shock: When electric current passes through the human body, it can cause an electric shock, which can be fatal.

Factors Affecting the Heat Produced in a Conductor:

When an electric current flows through a conductor, some of the electrical energy is converted into heat due to the resistance of the conductor. The amount of heat produced in the conductor is dependent on several factors, including:

1. Current: The higher the current flowing through the conductor, the greater the amount of heat produced.

2. Resistance: The higher the resistance of the conductor, the greater the amount of heat produced.

3. Time: The longer the current flows through the conductor, the greater the amount of heat produced.

4. Material: Different materials have different resistances and will therefore produce different amounts of heat for the same current flowing through them.

5. Cross-sectional area: The larger the cross-sectional area of the conductor, the less the amount of heat produced for the same current flowing through it.

6. Temperature: The temperature of the conductor also affects the amount of heat produced. As the temperature of the conductor increases, its resistance also increases, and more heat is produced for the same current flowing through it.

The most likely true statement about asynchronous communication is that it is helpful when employees work across multiple time zones.

Asynchronous communication refers to a mode of communication where participants do not need to be present or engaged simultaneously. Instead, they can send and receive messages at their convenience.In today's globalized society, businesses often have teams distributed across different geographical locations and time zones.
