Answer:
a)115 N
b)For father acceleration = 1.69 m/s²
For son acceleration = 3.28 m/s²
Explanation:
Given that
Mass of man(M)= 68 kg
Mass of son (m)= 34 kg
F= 115 N
As we know that from third law of Newtons ,It sates that every action have it reaction in opposite direction but same in magnitude.
So the force exerted by boy on father = 115 N
From Newtons second law of motion
F= m a
F=Force
m= mass
a=acceleration
For father
115 = 68 x a
a=1.69 m/s²
For son
115 = 35 x a'
a'=3.28 m/s²
Answer:
10 km
Explanation:
You can draw your problem out. You can use the pathagoran theorem to figure it out. So 
+ 
and then square root the answer which will be 
which equals to 10.
The best answer would be C.
The mass of an element depends on the number of particles found in the nucleus of the atom. Atomic mass can be computed by adding the number of protons and the number of neutrons. Protons and neutrons are found in the nucleus of an atom. So the answer must be letter C.
Explanation:
The ball, for example, will feel gravity pulling it downward and the ground pushing it upward in the direction it is rolling. (Add this if the ball is rolling on the floor.) Friction is the force that causes the ball to slow down because it acts in the opposite direction that it is moving.

Answer:
Explanation:
The index of refraction is equal to the speed of light c in vacuum divided by its speed v in a substance, or 
. For our case we want to use 
, which for our values is equal to:
Which we will express with 3 significant figures (since a product or quotient must contain the same number of significant figures as the measurement with the <em>least</em> number of significant figures):
