Answer:
<u>Option-(D):</u>Thermal energy unchanged, temperature decreased.
Explanation:
<u>Thermal energy and Temperature,T:</u>
Thermal energy of the system is remained unchanged while the temperature,T of the objects present inside the system is more associated with the objects fundamental properties which each matter shows or exhibits in nature.
While the thermal energy is the flow or exchange of thermal or heat energy between the different objects in interaction to each other.
Because gravity and it's force pushes an object down
Answer:
it transfers energy as it moves

Answer:
0.0231 m/s
Explanation:
Given the question :
A small toddler is playing in his yard. Over the course of 29.01 s, he walks 2.099 m S before turning N and walking 1.429 m. What is his average velocity?
Distance walked south = 2.099 metre
Time taken = 29.01s
Distance walked north = 1.429 metre
Average Velocity = Displacement / time
The Displacement is hence,
(2.099 m - 1.429m) = 0.67m
Average Velocity = 0.67m / 29.01s
Average Velocity = 0.02309 m/s
Average Velocity = 0.0231 m/s
