The weight of an object isa. the force of gravity on its mass.
b. the amount of matter in an object.
c. the tendency of an object to resist motion.
d. the tendency of an object to continue moving in a straight line.

Answers

Answer 1
Answer:

The weight of an object is the force of gravity on its mass. The answer is letter A. The acceleration due to gravity is the acceleration on an object caused by force of gravitation. It means that the earth has a gravitational field that projects all bodies on earth towards its center. The gravity of an object or body of an object is high on earth than at the atmosphere. It has an average of gravitational constant equal to 9.8066 or 9.8 meters per second. In truth, the acceleration of the object depend upon its location, the latitude and altitude, on earth.

If a ball with an original velocity of zero is dropped from a tall structure and it takes 7 seconds to hit the ground, what velocity does the ball have when it reaches the ground? A. 34.3 m/s B. 68.6 m/s C. 156.8 m/s D. 240.1 m/s

Answers

The velocity of the ball when it reaches the ground is equal to B. 68.6 m/s. This value was obtained from the formula Vf = Vi + at. Vf is the final velocity. Vi is the initial velocity. The acceleration is "a", while the time of travel is "t". The solution is:

Vf = Vi + at
Vf = 0 + (-9.8 m/s^2) (7 s)
Vf = -68.6 m/s

The negative sign denotes the direction of the ball.

Radiation transfers energy by moving matter. Please select the best answer from the choices provideda. True
b. False

Answers

The answer is b. False because radiation transfers energy by the propagation of waves within the electromagnetic spectrum and the travel of photons. Therefore, no matter is moved within this process.

False

A stone is dropped from a bridge and hits the pavement below in two seconds. What is the velocity of the stone when it hits the pavement?A. 0.20 m/s
B. 19.6 m/s
C. 4.9 m/s
D. 9.8 m/s

Answers

We have: a = v/t
Here, t = 2 s  [ Given ]
a = 9.8 m/s²  [constant value for earth system ]

Substitute their values into the expression:
9.8 = v/2
v = 9.8 × 2
v = 19.6 m/s

In short, Your Answer would be Option B

Hope this helps!

i just did the quiz and so the only 2 options that made logical sense would be B (19.6 m/s) or D (9.8 m/s) the reason someone could get confused between these two is because 19.6 divided by 2 is 9.8 m/s so for each second it will go down 9.8 m/s but since it wants to know the velocity it would be 19.6 m/s

hope this helps
