The moon remains in orbit around earth because of gravitational energy

Data;

Moon and other centripetal bodies maintain a state of constant orbit or centripetal acceleration because of gravitational energy.

The gravitational energy acting on the moon keeps the body rotating. This is further elaborated by Einstein's theory of relativity.

Answer:

12V

Explanation:

from the formula, I=V/R

V=IR

V=24x0.50

Voltage difference in a circuit = 12V

Answer:

S = 1/2 Vo t + 1/2 a t^2 = d      time for particle to travel distance d

F = E q         force acting on particle

a = F / m = E q / m

d = Vo t + E q / (2 m) t^2

One would need to solve the quadratic equation shown to find the time t

t^2 + (2 m) / E q * V0 t - (2 m) / E q * d = 0

or t^2 + A V0 t - A d = 0 where A =  (2 m) / E q

Answer:

Personally I say the yellow truck but...

Explanation:

It's heavily based on the object's mass...

If you know which object has the most mass than I would choose that one, but personally I think the yellow one has the most mass...

The energy to the position is known as potential energy. The maximum potential energy is in case 2. Hence the maximum height will be in case 2.

The energy of the body by the virtue of its motion is known as the kinetic energy of the body. It is defined as the product of half of mass and square of the velocity.

According to the law of conservation of energy, the total energy is defined as the sum of kinetic energy and potential energy.

Mechanical energy = kinetic energy+potential energy

Potential Energy = Mechanical Energy - Kinetic Energy

As a result, if an object has greater potential energy, it will have a higher height.

The formula for the kinetic energy is given by;

The potential energy for the different cases will be;

Case-1;

[tex]\rm KE_1=\frac{1}{2}mv^2 \\\\ \rm KE_1=\frac{1}{2}\times2.4(7)^2 \\\\ \rm KE_1=58.8 J[/tex]

[tex]\rm PE_1 = 32 - 58.8 = -26.8 J[/tex]

Case-2;

[tex]\rm KE_2=\frac{1}{2}mv^2 \\\\ \rm KE_2=\frac{1}{2}\times2.4(2)^2 \\\\ \rm KE_2=4.8 J[/tex]

[tex]\rm PE_2 = 34 - 4.8 = 29.2 J[/tex]

Case-3;

[tex]\rm KE_3=\frac{1}{2}mv^2 \\\\ \rm KE_3=\frac{1}{2}\times2.4(6)^2 \\\\ \rm KE_2=43.2 J[/tex]

[tex]\rm PE = 35 - 43.2 = -8.2 J[/tex]

Case-4;

[tex]\rm KE_3=\frac{1}{2}mv^2 \\\\ \rm KE_3=\frac{1}{2}\times2.4(3)^2 \\\\ \rm KE_2=10.8 J[/tex]

[tex]\rm PE_2 = 31 - 10.8 = 20.2 J[/tex]

The maximum potential energy is in case 2. Hence the maximum height will be in case 2.

f is the focal length =  -4. 5 cm

u is the object distance=12. 0 cm

v is the image distance =?

[tex]\rm \frac{1}{v} +\frac{1}{12.} =\frac{1}{-4.5} \\\\ \rm \frac{1}{v}= \frac{1}{-3} \\\\ \rm v= -3cm[/tex]

Answer:

D. Wavelength

Explanation:

Explanation: the colour of visible light depends on the wavelength of the wave. The visible light spectrum goes approximately from wavelength of 380 nm (corresponding to violet light) to 750 nm (corresponding to red light), and the different colours in between correspond to different wavelengths.

Answer:

b) Potential energy decreases

Explanation:

The reason why Potential energy decreases here is because you know that if you bounce a ball without applying any force to it, then it falls, and then comes back up, but does it come all the way up to where it was fallen from? NO! So that's why, each time the ball bounces, the potential energy goes down.

True; Destructive occurs for two interfering waves that are 180 degrees out of phase

Answer:

5 times as much

Explanation:

the equation for momentum is p=mv

p(momentum)=m(mass)xv(velocity)

So if the velocity is the same, but the mass is multiplied by 5 the total momentum would be 5 times greater than the previous scenario.

L = r x p = rmv = mr²ω

L = 0.25 x 0.75² x 12.5 = 1.758

Angular momentum of a 0.25 kg mass rotating on the end of a piece of rope in a circle of radius 0.75 m at an angular speed of 12.5 rad/s is 1.758.

The meaning of MOMENTUM is a property of a moving body that the body has by virtue of its mass and motion and that is equal to the product of the body's mass and velocity. Momentum is a vector quantity.

Angular momentum is momentum in angular motion,

L = r x p = rmv = mr²ω

L = 0.25 x 0.75² x 12.5 = 1.758

Angular momentum of a 0.25 kg mass rotating on the end of a piece of rope in a circle of radius 0.75m at an angular speed of 12.5 rad/s is 1.758.

Answer:I added my whole lab report into here let me know if this the what you need

Explanation:

Answer: There is two event that needs to be made: 1. blue eyes, and 2. brown eyes. A spinner is made with a circle. A full circle has 360 degrees and it would be divided based on the probability of the event.

Blue eyes have 25% chance, so the angle of the spinner would be 25%*360°= 90°

Brown eyes have 75% chance, so the angle of the spinner would be 25%*360°= 270°

So, the 90° of the circle would be written as 1(blue eyes) and 270° of the circle will be written as 2(brown eyes).

Answer:

B and D

Explanation:

Both a CD and alarm clock have magnetic properties of metal alloys and polymers.

We know that,

Heat lost by the sphere = Heat gained by H₂O & Calorimeter

=> m₁ x c₁ x ∆T₁ = m₂ x c₂ x ∆T₂ + c₃ x m₃ x ∆T₂

=> 0.047 kg x c₁ x 77°C = 0.25 kg x 4.18 x 3°C+0.14 x 0.386 x 3°C

=> c₁ = ( 0.25 kg x 4.18 kg^-1 k^-1 x 3°C + 0.14kg x 0.386 kg^-1 k^-1 x 3°C ) / 0.047 kg x 77°C

=> c₁ = 3.30/ 0.047 x 77

=> c₁ = 0.913 KJ kg^-1 k^-1

Hence , the specific heat capacity of aluminum would be 0.913 KJ kg^-1 k^-1

Answer:

F = M a    where F is in lbs, M in slugs and a in ft/s^2

Apparently this system is motionless so

T + 15 is the downward force on the mass of 15 lbs

1 slug * 32 ft/s^2 is 32 lbs the weight of the other block

It takes a force of 32 / 2 = 16 lbs on the cable to support this weight

16 lbs = T + 15 lbs

T = 1 lbs

Answer: Experimental design means creating a set of procedures to test a hypothesis. A good experimental design requires a strong understanding of the system you are studying. By first considering the variables and how they are related ( Step 1 ), you can make predictions that are specific and testable

Explanation:

A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used interchangeably, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research, in a process beginning with an educated guess or thought.
