Question

@theredhead1617
Which is true about the dependence of an object's weight upon its location in the universe?

Answer 1

A. Because gravitational force is the magnitude of weight acting on an object's mass and weight varies in different places in the universe, both the gravitational force on an object and its mass also vary.

B. Because weight is the amount of matter in an object and gravitational force is indirectly proportional to weight, both gravity and weight vary in different places in the universe.

C. Because weight is the magnitude of gravitational force acting on an object and gravitational force varies in different places in the universe, the weight of an object also varies.

D. Because gravitational force is the magnitude of weight acting on an object and weight varies in different places in the universe, the gravitational force on an object also varies.

Answer 2

Mass almost never changes
gravity, thus weight, depends on the presence of other massive bodies nearby

So, it's C

"Because weight is the magnitude of gravitational force acting on an object and gravitational force varies in different places in the universe, the weight of an object also varies. "

@theredhead1617 Thanks! :)

During a golf game, the ball is hit forward with 500 N of force using a golf club. According to Newton's Third Law of Motion, what is the force of the golf ball on the club?

A. To determine the force on the golf ball, the force of 500 N by the golf club must be multiplied by gravity to get 4900 N.

B. The golf club exerted a forward force of 500 N on the golf ball. This activated a 500 N force of inertia from the golf ball to the golf club.

C. The golf club exerted a forward force of 500 N on the golf ball, so the golf ball exerted a backward force of 500 N on the golf club.

D. The golf club exerted an attractive force of 500 N on the golf ball, so the golf ball exerted a repulsive force of 500 N on the golf club.

Answer 4

I'm not quite sure on that and I don't wanna get it wrong. Any other questions tho?

A handball player hit a ball with a mass of 0.25 kg. The ball travels at a velocity of 15 m/s for 0.75 s until it hits the wall.

What was the average acceleration of the handball?

A. 20 m/s²

B.0.05 m/s

C.0.05 m/s²

D.20m/s

Answer 6

Is this all the info they give?

Answer 7

Yeah, they're not very good at wording the questions.

Answer 8

Acceleration is Change in velocity over time.
Change in velocity is form 0 to 15m/s and time is 0.75sec
15/0.75= 20m/s^2
