B. energy conservation
C. energy transformation
D. Other:

Answers

Answer 1
Answer: Energy Transformation
Answer 2
Answer:

Answer:

Energy transfer is the movement of energy from one location to another. Energy transformation is when energy changes from one type to another. While energy can be transferred or transformed, the total energy always remains the same.

Which statement best compares the accelerations of two objects in free fall? A) The heavier object has a greater acceleration.
B) The object that has the greater surface area has the lower acceleration
C) The object that has the smaller mass has the greater acceleration
D) The objects have the same acceleration

Answers

Answer: option D). The objects have the same acceleration.

The acceleration of both objects is g (acceleration of gravity).

In freefall the only force acting is the attraction of the earth (gravity). There is not air resistance.The acceleration is not dependent either of the mass or the surface area of the object.

The answer is: D) The objects have the same acceleration.

If a car travels 60 mi. north for one-half hour, 100 mi. west for one hour, and 60 mi. south for 30 minutes, what is the total displacement of the car?100

220

0

Is The direction N, S, E, W, or N/A

Answers


The first and the last segment ... 60 mi north and 60 mi south ... canceled
each other. The only segment left is the 100 mi west, so that's the overall
displacement ... 100 miles west.  The times don't matter at all.
I would say that the total displacement of the car would have to be in the Westward direction.

A truck accelerates 2 m/s2 when it is empty. If the truck is filled so that it has twice the mass and the same amount of net force is applied, how much will the truck accelerate?8 m/s2
1 m/s2
4 m/s2
2 m/s2

Answers

Answer :

a = 1 m/s^2

Explanation:

Given information

Net force is a constant

The mass of the truck is m_(o)

Initial acceleration a_(o)= 2 m/s^(2)

The mass of the truck is increased twice as much

F_(net)= m_(o) a_(o) = ma

F_(net)= m_(o) a_(o) = 2m_(o)a

a=\frac{a_(o) } {2}

a = 2/2

a = 1 m/s^(2)
