Work
Explanation:
Energy can do work or bring about change.
Energy is simply the ability to do work. When work is done, changes occur in a body.
- There are different forms of energy and they are all related to work done.
- When work is done on a body, a force causes a change in that body.
- Both potential and kinetic energy are the same as work done.
- Energy is needed to do work.
- Work is done when a body changes energy.

Answer:
the metamorphic rock converts into other rock types under different conditions
Answer:
10 m/s
Explanation:
Given:
Amplitude of atomic vibrations (λ) = 10⁻⁹ cm = 10⁻⁹ × 10⁻² m = 10⁻¹¹ m [1 cm = 10⁻² m]
Frequency of the vibrations (f) = 10¹² Hz
In order to find the atom's maximum speed, we need to make use of the formula that relates speed, frequency and wavelength of the vibration.
Therefore, the formula for maximum speed is given as:
Now, plug in the values given and solve for speed 'v'. This gives,
Therefore, the atom's maximum speed due to thermal energy provided is 10 m/s.
