Answer:
5 seconds
Explanation:
Data provided in the question as per the question is as follows
Distance = 1,650 meter
Speed of the sound is 330 m/s
Based on the given information, the time taken is
As we know that
So,
= 5 seconds
We simply divided the total distance from the speed so that the time taken could be come and the same is to be considered
Answer:

Answer:
2. kinetic energy = total energy - potential energy
Explanation:
The total energy of a system is the addition of kinetic and potential energy of the system. Kinetic energy can be regarded as form of energy posses by an object when it's in motion
Total energy = kinetic energy + potential energy
(If we make Kinectic energy the subject of the formula, we have)
kinetic energy = total energy - potential energy
