They lower the average density of their body; because of the air it feels like a slight decrease in the weight.
Answer:
the moment of force is 25 Nm.
Explanation:
Given;
weight of the book, F = 50 N
distance through which his hand was stretched, d = 50 cm = 0.5 m
The moment of force is calculated as;
moment of force = F x r
moment of force = 50 N x 0.5 m
moment of force = 25 Nm
Therefore, the moment of force is 25 Nm.

Answer and Explanation:
The estimation of the mass of the objects is as follows
Given that
The mass of an apple is about 100 g
Just like that, we do some estimation of different objects
A dime is around 1 g
A smartphone is about 100 g
An adult male is approx 100 kg
A college physics textbook is around 1 kg
A ripe banana is around 100 g
A small car is around 1,000 kg
