Answer:
32.4 N
Explanation:
The force of gravity acting on the dog is equal to its weight on the Moon, which is given by

where:
m is the mass of the dog
g is the acceleration of gravity on the moon
In this problem, we have:
m = 20 kg
g = 1.62 m/s^2 (acceleration due to gravity on the moon)
Substituting numbers into the equation, we find

The second statement is correct : Gravity is a force that pulls objects towards Earth's centre.
Answer:
"12.4 g/mL" would be the right solution.
Explanation:
The given values are:
Mass of the object,
= 149.8 g
Volume of the object,
= 12.1 mL
Now,
The Density will be:
⇒ 
On substituting the given values in the above formula, we get
⇒ 
⇒
