Explain the difference between Longitudinal and Transverse waves.

The measured value of mass M in an experiment is M = 0.743 ± 0.005kg. The error in 2M is

omeli [17]

Given the measured value of mass M in the experiment the error in 2M is ; dM

<u>Given data :</u>

Measured value of mass M = ( 0.743 ± 0.005 ) kg

<h3>The error in 2M in the measured value </h3>

The error in 2M in the measured value M = 0.743 ± 0.005 kg is dM while the error in M² will be 2dM

Hence we can conclude that the measured value of mass M in the experiment the error in 2M is ; dM.

A man stands on a scale and holds a heavy object in his hands. What happens to the scale reading if the man quickly lifts the ob

Novosadov [1.4K]

Answer:

Explanation:

When he accelerates the heavy object up , the reading increases because an extra downward normal force acts on it, then scale reading returns to the same reading as when standing stationary, and then decreases as although he is lifting the heavy object , the acceleration is decreasing ,so the extra upward normal force acts.
