Answer:
27 N
Explanation:
It will be the force of the book 1.2 kg * 9.81 m/s^2 PLUS the force of your hand 15.3 N ..... it will be in the OPPOSITE direction
1.2 * 9.81 + 15.3 = ~27.1 N
It would be yes, once they pull the parachute they start to accelerate upwards
The suns energy is probably produced by <u>nuclear fusion</u>

Wavelength = (speed) / (frequency) = (460 m/s) / (230/sec) = <em>2 meters</em>
We will first convert all units to meters and then solve the problem.
We are given that:
1000 mm = 1 m
120 mm = ?? meters
using cross multiplication:
120 mm = (120*1) / 1000 = 0.12 m
Now, when the two objects are placed over each other, their total height is the result of summation of both heights, therefore:
total height = 0.12 + 1.5 = 1.62 m
Based on the above calculations, the correct choice is:
