The answer is B.
More mass means more gravitational force.
Hope it helps!
Answer:
Pressure, 
Explanation:
It is given that,
Combined mass of the man and the chair, m = 95 kg
Radius of the leg of chair, r = 0.5 cm = 0.005 m
A large man sits on a four-legged chair with his feet off the floor. The force acting per unit area is called the pressure exerted.
Area of 4 legs, A = 4 A
So, the pressure each leg exert on the floor is 
. Hence, this is the required solution.
<span>Electromagnetic waves differ fundamentally from either water or sound waves because they does not require any medium, they can travel in free space (vacuum)

option B open system
because in open system energy and mass can escape from the system or can be added to it.
The centripetal acceleration is 27.692 kg m / s^2.
The mass of the ball is 7.94 kg.
<u>Explanation:</u>
- The curved path of an object experience a force known as centripetal force. Its direction is always pointing to the motion of the body towards the center of curvature of the path.
centripetal force Fc = (mass * square of velocity) / radius
where m represents mass in kg
v represents velocity
r represents radius in a meter.
- The acceleration experienced in uniform circular motion is called as centripetal acceleration.It always points toward the center of rotation and is perpendicular to the linear velocity.
- centripetal acceleration = v^2 / r
= (6 * 6) / 1.3
= 27.692 kg m / s^2.
The mass of the ball is found by using the centripetal force formula,
- centripetal force Fc = m v^2 / r
m = (F * r) / v^2
= (220 * 1.3) / 36
mass of the ball m = 7.94 kg.
