Carla pushes a toy car and lets it go. The toy car rolls and gradually comes to a stop. What would make the car stop?A. A force must be applied to the car in the direction opposite to that in which it is moving.
B. A force must be applied pushing the car forward in the same direction as the moving car.
C. A force must be applied in a direction pushing the car upward to make the car stop.
D. A force must be applied in a direction pulling the car downward causing the car to stop.

Answers

Answer 1

Answer: A is correct :) If you push up or down on a toy car it won't nessicarily stop. If you push it in the same direction, it will probably go faster. If you push it in the opposite direction, it will stop. (Or go backwards depending on how hard you push)

Answer 2

Answer: A is correct because this creates friction so the car stops.

What acceleration does a 9 N force produce in a 3 kg object? Make sure to show your work. (The 4 steps)

Answers

Answer: 3m/s^2

Explanation:

Given that:

Acceleration of object = ?

Force = 9 N

Mass of object = 3 kg

Since force is the product of the mass of an object and the acceleration by which it moves i.e Force = mass x acceleration

9N = 3kg x acceleration

Acceleration = 9N/3kg

Acceleration = 3m/s^2 (3 metres per second square)

Thus, an acceleration of 3m/s^2 is produced.

Well,

Logically, the deeper we go, the hotter it will get.

It turns out that the innermost part of the lithosphere is the hottest, while the outermost part of the lithosphere is the hottest (suprise!).

A particle is moving in a circular path of radius r . The displacement after half a circle would be

Answers

Answer:

Explanation:

As we know that

The displacement is the total distance measured between the initial or start and final or destination point

If particle cover half path of the circle, the displacement can easily find out by considering the distance between the start and destination point

We attached the diagram for better understanding

As per the diagram.

The displacement after half-circle is

AB = OA + OB

= r + r

= 2r
