What do you think a black hole is

Answers

Answer 1

Answer:
A black hole is a object with a gravitational pull so strong, you have to reach the speed of light to escape. Since nobody can, when it happens, we are gone.

Answer 2

Answer: A black hole contains a large amount of gravitational force, which pulls everything near it inside.

A 0.09 kg marble sits at rest on the top of a sloping, frictionless track.a. If the slope has a height of 1.5 m, calculate the velocity of the marble at the bottom of
the slope.

Answers

Answer:

Explanation:

Notice that nothing but the mass and height are given, and the mass is not really necessary. It will cancel when we do the problem.

So the potential energy at the top equals the Kinetic energy at the bottom.

PE_top = Ke_bottom

mgh = 1/2 m v^2 Divide by m

mgh/m =1/2 mv^2/m

gh = 1/2 v^2 Multiply both sides by 2

2gh = v^2

g = 9.81

h = 1.5

Solution

2*9.81 * 1.5 = v^2

29.43 = v^2

v = sqrt(29.43)

v = 5.425

Sudhi is studying the motion of a toy car. she places the car in the middle of a ramp and releases it. which best describes the reference point in this scenario?

Answers

From the motion of the toy car, the reference point of this scenario is the starting position of the car.

What is reference point?

The reference point of an object is defined as the position through the measurement of an object is taken.

In studying the motion of a toy car, if she places the car in the middle of a ramp and releases it, we can conclude that the reference point of this scenario is the starting position of the car.

The starting position of the car will serve as point of reference because, the distance, speed, and time of motion of the car can be obtained with respect to the starting point.

Thank you for posting your question here. Below are the choices that can be found elsewhere:

a. the top of the ramp
b. the bottom of the ramp
c. the ending position of the car
d. the starting position of the car

I think the answer is D which is the starting position of the car. I hope it helps.

Julian stands on his toes to lift his body high enough so that he can reach a book. In this example, Julian's toes are aA) pulley
B) load
C) wedge
D) fulcrum
**its actual a physical science question**

Answers

Answer : (D) Fulcrum.

Explanation :

It is given that Julian stands on his toes to lift his body high enough so that he can reach a book. This is the example of a second class lever.

In the second class lever, the load is between the effort and the fulcrum.

In this case, the muscles provide the input force. His weight of the foot that is lifted up is the output force and toes act as a fulcrum.

So, the correct option is (D) Fulcrum.

Why do objects move at constant speed

Answers

Most objects move at a constant speed because of friction and acceleration. The constant speed keeps them in place, and keeps a balance.
