Answer: Potential energy is energy stored in an object due to its position or arrangement. Kinetic energy is the energy of an object due to its movement its motion. Potential energy can be converted into kinetic energy, and kinetic energy can be converted into potential energy.
Answer:
The duration of the movie is longer than 2 hrs.
Explanation:
Given:
The duration of the movie observed by the crew on the spacecraft is 2 hrs.
According to time-dilation formula:
Here, is the required time, is the original time, is the velocity of the spacecraft and is the velocity of light.
Since , so .
So the time required will be large.
Explanation:
You can solve for volume using radius or diameter.
Sphere Volume = 4/3 • π • r³ = ( π •d³)/6
We're given the diameter so let's use that.
Volume = PI * d^3 / 6
Volume = 3.14159 * 3.0^3 / 6
Volume = 3.14159 * 9 / 2
Volume = 14.137 cubic centimeters
