Answer:
a) 245 N
b) 392 J
c) 196 W
Explanation:
a) Force needed to lift the 25 kg object is the same as the weight of the object:

b) Work is the force exerted times the distance moved:

c) The power exerted is the quotient of the work done over the amount of time it took to move the object:
Inertia is the name. Inertia is when a moving object stays in motion unless stopped by an outside force. This is Newton’s first law of motion
Answer:
Science can only answer inquiries about effects and events that are discovered, defined, and studied in the material realm. It cannot answer questions about the one basic cause of all effects and events.
Answer: The correct answer is "same frequency".
Explanation:
Resonance occurs when the natural frequency of the object matches with the applied frequency.
Standing wave is the stationary wave in which there is an interference of the wave moving in an opposite direction each having same frequency and same amplitude.
Resonance is the response of a standing wave to another wave when the frequency of the both waves are same.
Therefore, the answer is "Same frequency".
