If it takes 5. 0 years for juno to reach jupiter, what is its average speed in mi/hr over this period?.

73 miles per hour speed will the car average 15 miles per gallon.

Velocity, as opposed to speed, refers to the pace and direction of such an object's travel as it moves down a path. Alternatively, velocity is a vector while speed is a scalar quantity.

The pace at which distance and time change is what is meant by speed. It has the aspect of temporal and spatial remoteness. The combination of the fundamental units of distance and time is what is described as the SI unit of speed. As a result, the SI unit of speed is the meter per second.

Given that,

When going more than 38 miles per hour, the gas mileage of a certain car fits the model: y = 43.81 - 0.395x

let, suppose y = 15

now, 15 = 43.81 - 0.395x

or, -28.81= - 0.395x

or, x = 72.9367 = 73 miles per hour to get 15 miles per gallon.

Answer: The longer the lever, the greater the force on the load will be.

Explanation:

The speed of a sound wave in air is 341.33 m/s when the temperature of the air is 17.3 °C.

In terms of physics, sound is a vibration that travels through a transmission medium like a gas, liquid, or solid as an acoustic wave. Sound is the reception of these waves and the brain's perception of them in terms of human physiology and psychology.

At 0° C,  speed of sound in air is  = 331 m/s

speed of sound ∝ √T

Hence, at 17.3°C, the speed of sound in air is = 331 m/s ×√{(273+17.3)/273}

Answer:

lightning conductors/rods protect buildings by intercepting lightning strikes that may hit these structures.

Air conditioners pass air over cold coils known as evaporator pipes

Explanation:

Lightning rods are made of highly conductive metal, and offer a path of least resistance for any lightning strikes and are connected to longer wires that ground the charge.

air conditioners use a chemical compound called a refrigerant. the most common refrigerant used is r-134a also know as 1,1,1,2-Tetrafluoroethane.  cooling systems use the low boiling points of these refrigerants to constantly cool and compress the chemical to continually move heat from the inside of the system to an external area.

2.15 s time  it take the can to hit the floor when a can of bean rolls off a horizontal table with a velocity of 0.44 m/s

velocity=distance/time

time=distance/velocity

time=0.95/0.44

time=2.15 s

A vector number called velocity can be used to express "the speed at which an object changes its location." Imagine someone moving quickly while taking two steps forward and two steps back, all while remaining in the same place. A vector quantity is velocity. As a result, velocity is aware of direction. When calculating an object's velocity, the direction must be taken into consideration. A speed of 55 miles per hour is insufficient detail. The velocity of the item must be properly described in terms of the direction. Simply explained, the velocity vector's direction shows how an item is moving.

The de Broglie wavelength of the electron is 2.212 x 10-11 m.

The de Broglie wavelength is a concept in quantum mechanics which states that all matter has a wave-like nature, and can thus be described as a wave.

(a) The de Broglie wavelength (λ) of a particle is given by the equation: λ = h/p, where h is Planck's constant (6.626 x 10-34 J.s) and p is the momentum of the particle.
The momentum of an electron with a 1000-V potential drop is given by the equation p = eV/c,
where e is the electron charge (1.602 x 10-19 C) and c is the speed of light (2.998 x 108 m/s).
Therefore, the de Broglie wavelength of the electron is:
λ = h/(eV/c) = (6.626 x 10-34 J.s) / (1.602 x 10-19 C x 1000 V/2.998 x 108 m/s) = 2.212 x 10-11 m.

(b) X-rays are produced when high-energy electrons strike a solid.
The wavelength of the x-ray is inversely proportional to the energy of the electron.
The energy of the electron is equal to the potential drop, i.e. 1000 eV. Therefore,
the wavelength of the x-ray produced is: λ = hc/eV = (6.626 x 10-34 J.s x 2.998 x 108 m/s)/(1.602 x 10-19 C x 1000 eV) = 1.246 x 10-10 m.

The charge is q1 = 9.4 nC

The charge q2 = -2.31 nC

The distance between them is r = 4.94 cm

To find the electric field strength at the midpoint between two charges.

Explanation:

The electric field strength at the midpoint will be the sum of electric field strength due to q1 and q2.

The electric field strength can be calculated by the formula

Here, k is the electrostatic constant whose value is

The electric field strength due to the charge q1 is

The electric field strength due to the charge q2 is

The electric field strength at the midpoint will be

Thus, the electric field strength at the midpoint between the two charges is 173000 V/m

Answer:

La fuerza resultante sobre q₃ es  -1.2245 × 10⁻¹⁵ i  + -0.24 × 10⁻¹⁵ j

La magnitud de la fuerza resultante sobre q₃ es aproximadamente 1.25 × 10⁻¹⁵ N

Explanation:

q₁ = -45 μC = -45 × 10⁻⁶ C

r₁₂ = 30 mm = 30 × 10⁻³ m

q₂ = 25 μC = 25 × 10⁻⁶ C

r₂₃ = 50 mm = 50 × 10⁻³ m

q₃ = 20 μC = 20 × 10⁻⁶ C

k = 9×10⁻⁹ N·m²/C²

Por lo tanto;

r₁₃ = √(50² + 30²) = 10·√(34)

F₁₂ = 9×10⁻⁹ × (-45 × 10⁻⁶)×(25 × 10⁻⁶)/(30 × 10⁻³)² = -1.125 × 10⁻¹⁴

F₁₂ = -1.125 × 10⁻¹⁴ N

F₂₃ = 9×10⁻⁹ × (20 × 10⁻⁶)×(25 × 10⁻⁶)/(50 × 10⁻³)² = 1.8 × 10⁻¹⁵ j

F₁₃ = 9×10⁻⁹ × (-45 × 10⁻⁶)×(20 × 10⁻⁶)/(10·√34 × 10⁻³)² = -2.38× 10⁻¹⁵

Los componentes de F₁₃ son;

-2,38 × 10⁻¹⁵ × cos (arctan (30/50)) = -2,04 × 10⁻¹⁵ j

-2,38 × 10⁻¹⁵ × sin (arctan (30/50)) = -1,2245 × 10⁻¹⁵ i

La fuerza resultante sobre la carga q₃, \(\left | \underset {F_3} \rightarrow \right |\) = \(\underset{F_{13}}{\rightarrow}\) + \(\underset{F_{23}}{\rightarrow}\)

∴ \(\left | \underset {F_3} \rightarrow \right |\) = 1.8 × 10⁻¹⁵ j + -1.2245 × 10⁻¹⁵ i + -2.04 × 10⁻¹⁵ j

La fuerza resultante sobre q₃ es \(\left | \underset {F_3} \rightarrow \right |\)  = -1.2245 × 10⁻¹⁵ i  + -0.24 × 10⁻¹⁵ j

La magnitud de la fuerza resultante sobre q₃,

\(\left | F_3 \right |\) = √((-1.2245 × 10⁻¹⁵)² + (-0.24 × 10⁻¹⁵)²) ≈ 1.25 × 10⁻¹⁵

Explanation:

Heat transfer across the walls due to conduction is given by:

\(q = -KA\frac{\Delta T}{L}\)

where,

q = heat transfer rate

K = thermal conductivity

A = Area

ΔT = change in temperature

L = thickness

For wall A:

\(q_A = -K_AA\frac{\Delta T}{L_A}\)

For wall B:

\(q_B = -K_BA\frac{\Delta T}{L_B}\)

Because the change of temperature and area of walls are the same. Dividing both terms:

\(\frac{q_A}{q_B} = \frac{\frac{K_A}{L_A} }{\frac{K_B}{L_B}}\\\\ \frac{q_A}{q_B} =\frac{\frac{K_A}{K_B} }{\frac{L_A}{L_B}}\)

The linear coefficient of thermal expansion for steel is 11 ×10⁻⁶ /°C. Then the temperature change between the days if the railroad tracks are 3 m long is 30.3 °C.

Thermal expansion is the change in length of a material with respect to change in temperature. The measure of expansion by an increase of 1°C is called its linear coefficient of thermal expansion.

We have the relation between change in length ΔL and change in temperature ΔT with linear coefficient α as follows:

ΔL = α L ΔT

Given ΔL1 = 3 - 0.0012 m = 2.998

ΔL2 = 3 - 0.0027m = 2.997

then ΔL1 - ΔL2 = α L ΔT = 0.001

α for steel = 11 ×10⁻⁶ /°C

ΔT  = 0.001/ (11 ×10⁻⁶ /°C × 3)

      = 30.3 °C

From the given situation we conclude that the plant with the smooth seeds is homozygous for the dominant trait.

There is no possibility of having children with wrinkly seeds. Only when the parent plant with smooth seeds is homozygous for the dominant characteristic is this conceivable. As a result, the parents plants' offspring will only exhibit the smooth characteristic, and there won't be any possibility of wrinkled seeds.

Gregor Mendel, an Austrian monk, developed a novel theory of inheritance based on his experimental work with pea plants in the 1860s. Most people thought heredity resulted through the blending of parental "essences" before Mendel, much as how combining blue and yellow paint will yield a green hue. Mendel, on the other hand, thought that each distinct unit (or gene) in an individual's genome acted independently to produce heredity, which is the product of discrete units of inheritance. This Mendelian idea holds that it is through the transmission of these units that a characteristic is passed on. An individual receives one gene for every parent, resulting in a pair of two genes for any given trait.

Answer:

It is not still true that the average velocity of the particle is equal to half the sum of the initial and final velocities when the acceleration of the particle is not constant

Explanation:

The motion of a particle under constant acceleration, 'a', is be given by the following kinematic equations;

v² = u² + 2·a·s

v = u + a·t

Where;

v = The final velocity of the particle

u = The initial velocity of the particle

a = The acceleration of the particle

s = The distance through which the particle travels

t = The time of motion of the particle

By simplifying the above equation, we have;

v² - u² = 2·a·s

(v² - u²)/(2·a) = s

(v - u) × (v + u)/(2 × a) = s

((v - u)/a) × ((v + u)/2) = s

From v = u + a·t, we have;

t = (v - u)/a

∴ ((v - u)/a) × ((v + u)/2) = t × ((v + u)/2) = s

∴ ((v + u)/2) = s/t

The average velocity = (Total distance traveled by the particle) ÷ (The time of travel of the particle)

∴ The average velocity = s/t = ((v + u)/2) = Half the sum of the initial and final velocity

However, it is not still true that the average velocity of the particle is equal to half the sum of the initial and final velocities when the acceleration of the particle, 'a', is not constant, as the velocity time graph is no longer a straight line graph and the distance traveled by the particle, 's', which is the area under the velocity time graph, 'A', (given by the sum of area of the triangle and the rectangle given by the area under straight line graph for constant velocity) cannot be given directly by the product of the time and the average velocity.

The statement is TRUE.

"Displacement" means the distance and direction from the start-point to the end-point, NO MATTER how you got there.

If you go out cycling and go back home when you're done, your displacement is zero.  it doesn't matter how far you cycled, or what streets or woods you cycled through, or whether your route was a circle, a square, an ellipse, a triangle, or a jumble, or whether you cycled around and around the same path 27 times.  You ended right where you started.  The distance from your start-point to your end-point is zero, so your displacement is zero.

Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible.

Explanation:

or it could be this

The type of energy that travels to Earth from the sun in the form of electromagnetic waves is called solar energy or solar radiation. This energy is generated by the sun's fusion reactions in its core and travels to Earth through space at the speed of light in the form of electromagnetic waves, which include visible light, ultraviolet (UV) radiation, and infrared (IR) radiation.The sun emits energy in the form of electromagnetic radiation which is transferred through space until it reaches the Earth's atmosphere. When this energy reaches the Earth, some of it is absorbed by the atmosphere, while the rest reaches the Earth's surface and is absorbed by the land, oceans, and atmosphere. This energy is essential for life on Earth as it drives the Earth's climate and weather patterns, and is also the primary source of energy for photosynthesis, which is the process by which plants convert sunlight into chemical energy.

Thus, the correct option is B.

Answer:

In the same way that velocity is the rate of change of displacement, acceleration is the rate of change of velocity. In other words, whenever a car increases its velocity, it is said to be accelerating and whenever it is slowing down, it is said to be decelerating.

Acceleration is a measure of how quickly the velocity of an object changes. So, the acceleration is the change in the velocity, divided by the time. ... The units for acceleration are meters per second squared (m/s2).

When two identical masses are attached by a light string that passes over a frictionless pulley, the system is in equilibrium. The tension in the string on each side of the pulley is equal to the weight of each mass.

Based on the given information, we have two identical masses connected by a light string that passes over a small pulley. The table and pulley are both frictionless.

Since the masses are moving, we can assume that there is some force acting on them. In this case, the force is provided by the difference in tension in the string on either side of the pulley.

To solve the problem, we need to consider the forces acting on the masses. The weight of each mass is acting downward, and we can denote it as mg, where m is the mass and g is the acceleration due to gravity.

Since the masses are identical, the weight of each mass is the same, so the tension in the string on each side of the pulley is also the same.

Let's assume that mass 1 is on the left and mass 2 is on the right. The force of tension in the string on the left side of the pulley is equal to the weight of mass 1, which is mg.

The force of tension in the string on the right side of the pulley is equal to the weight of mass 2, which is also mg.

Now, since the masses are identical, the forces of tension are equal in magnitude but opposite in direction. Therefore, the net force acting on the system is zero, resulting in a balanced system.
