Answer:
Thermal energy
Explanation:
The thermal energy associated with the random motions of the atoms or molecules.
When the temperature of the substances rise then their molecule starts to vibrate within the system and the energy associated with the vibration of the molecule is known as thermal energy.The responsible factor for the rise in temperature is thermal energy.
Therefore answer is --
Thermal energy

Answer:
a. 0.01 C
b. dissipated to outside environment
Explanation:
Let the specific heat of copper be 0.3846 kJ/kg-K or 384.6 J/kg-C
(a)The original kinetic energy of the block is:
As 85% of this kinetic energy is converted to block internal heat energy, with specific heat we can calculate the rise in temperature:
(b) the remaining 15% energy would probably be dissipated to outside environment as heat energy
3. C: Heavily populated with trees.
4. A: Tundra has the lowest humidity
Answer:
We know that the time period of the vibration of the second's pendulum is T=2s. Hence, the length of the second's pendulum is 99.3 cm
