<span>Satellite in a circular orbit of radius r around planet x has an orbital period t. if planet x had one-fourth as much mass, the orbital period of this satellite in an orbit of the same radius would be 2t</span>
Answer:
2.74 N-s
Explanation:
m = mass of the basketball thrown towards the floor = 0.60 kg
v₀ = initial speed of the ball before hitting the floor = 5.4 m/s
θ = angle made by the direction of motion of the ball with the vertical before and after the collision = 65°
I = Impulse delivered to it by the floor
Impulse delivered to the ball by the floor is given as
I = 2 m v₀ Cosθ
Inserting the values
I = 2 (0.60) (5.4) Cos65
I = 2.74 N-s
The diagram represents a chain reaction that is caused by nuclear fission.
<h3>What is a nuclear fission reaction?</h3>
A nuclear fission reaction is a reaction in which the nucleus of a larger atom is split into two or more smaller nucleus of atoms.
Nuclear fission can proceed in the form of a chain reaction in which the products of the first fission reaction are used to initiate further fission reactions.
Therefore, the diagram represents a chain reaction that is caused by nuclear fission.

Answer:
N = 19.6 N
Explanation:
Given that,
Mass of a block, m = 2000 g
1 kg = 1000 g
It means, 2000 g = 2kg
We need to find the value of normal force on the block on a table. Normal force is balanced by the weight of the block as follows :
N = mg, g is acceleration due to gravity
N = 2 kg × 9.8 m/s²
N = 19.6 N
So, the normal force acting on the block is 19.6 N.
