Answer:

In standard GR, nothing exists at the center of a black hole. The center of a black hole is a singularity, and because GR fails at that point it is simply removed from the manifold. That means that the singularity is not part of spacetime.

To answer your question more realistically, we believe that GR is an approximate theory that fails well before you reach the center. Unfortunately, we have no good alternative theory with which to answer the question in the region where GR fails. We simply don’t have any data from that regime and it is very hard to formulate a good theory without data. So there very well could be time at the center, but we simply don’t have a good way to even guess.

Answer:

Black hole is a region of space having a gravitational field so intense that no matter or radiation can escape

Actually time can't be stop.

although black hole slower a time

Explanation:

Time never cannot be stop totally.

Skateboard A Force: 33 N Time: 0. 12 s Skateboard B Force: 33 N Time: 0. 57 s Skateboard C Force: 33 N Time: 0. 78 s Which skate

Snowcat [4.5K]

The skateboard that has the greatest impulse is Skateboard C (Impulse = 25.74 Ns)

From the question,

We are to determine which skateboard has the greatest impulse. To do this, we will calculate the impulse of each skate board.

Impulse can be calculated by using the formula

I = Ft

Where I is the impulse

F is the force

and t is the time

For Skateboard A

Force = 33 N

Time = 0. 12 s

∴ Impulse = 33 × 0.12

Impulse = 3.96 Ns

For Skateboard B

Force = 33 N

Time = 0. 57 s

∴ Impulse = 33 × 0.57

Impulse = 18.81 Ns

For Skateboard C

Force = 33 N

Time = 0. 78 s

∴ Impulse = 33 × 0.78

Impulse = 25.74 Ns

Hence, the skateboard that has the greatest impulse is Skateboard C (Impulse = 25.74 Ns)

2 spheres are made from the same material. One is smaller and one is larger. Is the smaller sphere made up of smaller atoms than

motikmotik

No because because they are made up of the same material so that means same size of atoms! I hope this helps

How to find the frictional force acting on an object (not the friction coefficient)? ...?

Dovator [93]

One can simply find the frictional force acting on an object using this equation:

(Ffrict = μ•Fnorm)

The process of determining the value of the individual forces acting upon an object involve an application of Newton's second law (Fnet=m•a) and an application of the meaning of the net force. If mass (m) and acceleration (a) are known, then the net force (Fnet) can be determined by use of the equation.

Fnet = m • a

If the numerical value for the net force and the direction of the net force is known, then the value of all individual forces can be determined.
