Answer 2

To find the value of N, we can use the formula N = M * g * h / t, where M is the mass, g is the acceleration due to gravity, h is the height, and t is the time.

Given: M = 20 kg h = 10 m g = 9.8 N/kg t = 30 min

First, let's convert the time from minutes to seconds since the unit of time in the formula is seconds. 30 minutes = 30 * 60 seconds = 1800 seconds

Now, we can substitute the given values into the formula to find N: N = 20 kg * 9.8 N/kg * 10 m / 1800 s

Calculating this expression, we find that N is equal to 0.1088 N.

Please note that the value of N is rounded to four decimal places.
