Answer: 5.71kg and 10.33N
Explanation:
Recall,
Weight =mass × g
Where w = 56.0 N , g = 9.8 m/s2
56= m × 9.8
M = 56/9.8
M = 5.71 kg
At the surface of the moon, the mass still remains 5.71kg because it is a fundamental quantity it does not change irrespective of position.
Weight at the moon surface will change as a result of change in gravity. Hence, weight = mg
Where g=1.81m/s2, m= 5.71
W = 5.71×1.81
W = 10.33N

As more resistors are added in parallel across a constant voltage source, there are more paths for current to take. So more current dribbles out of the source, and the total current supplied by the source increases.
The power supplied by the battery is (voltage) x (current). So if the voltage is constant and the current increases, the power being supplied must also increase.

The net force that is applied to the passenger during the elevator acceleration is 218.75 N.
<h3>What is net force?</h3>
This is the single force obtained from the combinatiion of two or more forces
To calculate the net force that is applied to the passenger during the elevator's acceleration, we use the formula below.
Formula:
- F = m(v-u)/t............ Equation 1
Where:
- F = force
- m = mass
- v = Final velocity
- u = initial velocity
- t = time.
From the question,
Given:
- m = 70 kg
- u = 0 m/s
- v = 12.5 m/s
- t = 4 s
Substitute these values into equation 1
Hence, The net force that is applied to the passenger during the elevator acceleration is 218.75 N.
