The earths rotation makes the sky "move" and this rotates the view of the stars above.
The force on the box is:
F = mgsin∅
If we multiply by this with the distance it traveled, we will know the work done by the box.
W = dmgsin∅
This work will be converted to elastic potential energy in the spring which is:
1/2 kx². Equating these and substituting values:
1/2 * 170 * x² = 4 * 13 * 9.81 * sin(30)
x = 1.73 m
The box's maximum speed will at the point right before contact with the spring, when the compression is 0.
Answer:
The answer is they utilized light in a few spots to enlighten the subjects and to demonstrate their volume as masses.
Explanation:
That is the reason every one of the particles that move at the speed of light (e.g. photons) have zero rest mass. As a molecule with mass methodologies the speed of light, its vitality increments and winds up unbounded at the speed of light, which is the motivation behind why it can never be quickened to achieve that speed. However, you can state that the photon has relativistic mass on the off chance that you truly need to. In current wording, the mass of a protest is its invariant mass, which is zero for a photon.
Answer:
27 m/s²
Explanation:
Traveling in uniform circular motion will cause a centripetal acceleration, an acceleration towards the center of the circle.
The acceleration of an object in circular motion is defined as a = v²/r.
Let's set the radius to be 5 m, since it is always unchanging. Solving for the velocity using a = 3 m/s² and r = 3 m gives us:
The velocity is 3 m/s when the acceleration is 3 m/s² and the radius of the circular path is 3 m.
Now let's triple the velocity: 3 m/s → 9 m/s.
Let's solve for the acceleration using v = 9 m/s and r = 3 m.
- a = (9)²/3
- a = 81/3
- a = 27
The acceleration is 27 m/s² if you triple your speed.
This makes sense because a is directly proportional to v², meaning that if you triple your speed, you increase the acceleration a by a factor of 3², which is a 9 times increase.
As a sidenote, doubling your speed would increase the acceleration by a factor of 2² - a 4 times increase.
