What happens as a bungee jumper gets closer to Earth's surface?
A. Gravity decreases
B. His mass increases
C. Air resistance decreases
D. His velocity increases
Answers
Answer:
Velocity increases
Explanation:
Gravity is constant, except when discussing "apparent weight"
Mass is constant here
Air resistance would actually increase
Velocity DOES increase, because Earth is pulling the jumper downwards with an unbalanced force. The unbalanced force creates acceleration (-9.81 m/s^2), which means his velocity is increasing constantly.
Solve for the gravitational potential energy at point B.

GPE = m*g*h
Answers
Answer:
GPEb=67.86% of initial GPE at point a
Explanation:
It depends on how massive the ball is, but I can still give an answer comparing original GPE at point A to new GPE at B
GPEa=m*9.8*140
GPEa=1372(m)
GPEb=m*9.8*95
GPEb=931(m)
GPEb=0.6786*GPEa

Newton's second law states that the acceleration of an object is directly related to the force on it, and inversely related to the mass of the object. You need more force to move or stop an object with a lot of mass (or inertia) than you need for an object with less mass. .

Calculating net force
Answers
Answer:
0N.
Explanation:
Net force is the sum total of forces acting on an object.
The Fn which is the net force is
450+ (-250) + (-600)+ 600+ 0 + 250 + (-450)
= 450-250+(-600)+ 600+0+250-450
= 0N
The net force is 0

Newton’s Second Law of motion says that the acceleration of an object is related to the force and mass of the object. This equation is used to describe the relationship: F=ma, where f is the force, a is the acceleration, and m is the mass for the object in motion.

Why is ultraviolet radiation considered more dangerous to humans than infrared radiation?
ANSWER:Ultraviolet radiation has a shorter wavelength than infrared radiation, and thus, the waves have higher energy. This allows them to penetrate the first layers of skin on humans and can mutate the DNA in the cells of the skin. This can result in cancer because of the mutations caused by the ultraviolet radiation.

What is the velocity of a 24 kg object with 108 kg m/s of momentum?
A) 3 m/s
B) 4.5 m/s
C) 6 m/s
D) 84 m/s
Answers
Answer:
The velocity of the object is 4.5 m/s
Explanation:
Momentum is equal to mass times velocity. We can rearrange that relationship to say that velocity is equal to momentum divided by mass. With that we can say:
v = 108 kg m/s / 24kg
v = (108 / 24) m/s
v = 4.5 m/s

a force of 25N acts on an object. The work done by the force is 400J. How far dose the object move in the direction of the force?
A. 6.3cm
B. 16cm
C. 16m
D. 10km
Answers
C
Explanation:
d=w/f
d=400/25
d= 16
The distance moved by the object in the direction of the force is equal to 16 m. Therefore, option (B) is correct.
What is the work?Work can be demonstrated as the energy employed when a force is exerted to move an object through a specific distance. The work done depends upon both the exerted force on the object and the displacement.
The action of the force when the object is moving in a straight line in the direction of the exerted force over a distance 'd'.
W= F ×d
Where 'd' is the displacement, 'F' is the applied force and W is the work done.
Given, the work done by the applied force, W = 400 J
The force applied on the object, F = 25 N
The distance moved by the object, d = W/F
d = 400/25
d = 16 m
Therefore, the object moves a distance of 16 m in the direction of the force.
