Why the light can't escape black hole?​

Physics

NISA [10]3 years ago

Black holes affect the causal structure of spacetime in such a manner that all future light cones within a black hole lie within the event horizon of it.

Although photons are massless they have energy and have to obey the geometry of a curved spacetime. Since all future lies within the event horizon, photons are trapped inside the black hole.

Consider three drinking glasses. All three have thesame area base, and all three are filled to the same depth withwater. Glass A
Sergio [31]

Answer:

The correct answer is C.  All three have equal non-zero pressure

Explanation:

Pressure is the relationship between the force and the area of ​​a body, when the bodies are liquid the formula that

         P = rho g h

Where rho is the density and h the height of the liquid

We see that for this expression the pressure does not depend on the shape of the container, but on its height, as the three vessels have the same height, the pressure at the bottom is the same.

The correct answer is C   All three have equal non-zero pressure

Distant galaxies appear to be much larger than those nearby. true or false
jonny [76]

Answer:True

Explanation: Distant galaxies appear to be larger than those close by because of cosmic expansion. light from nearer galaxies travel farther and makes the other to be billions of years away. The farther it takes to get to another galaxy, the bigger it appears

In an evaporation of water experiment, the initial mass of water in a beaker was 10.5775 +/- 0.0002 g. After some time, the mass
muminat

Answer:

Explanation:

The theory of  propagation of error in case of addition and subtraction states that maximum errors are added in absolute terms in both the operation of addition and subtraction . So in this case the subtracted value will be

10.5775 - 10.3005

= .2770 g

errors will be added ie in subtracted value we can find error to the tune of

.0002 + .0002 = .0004 g

So the subtracted value will be written as

.2770 ± .0004

Two ideal solenoids of radii R and 4 R , respectively, have n turns per meter, and each carries a current of I . Both currents f
telo118 [61]

Answer:

The formula for the calculation of the magnetic field inside a solenoid is

B = μo*n*I

where

μo: vacuum permeability

n: turns per meter

I: current

The magnetic field inside de solenoid is constant. In the case of a small-radius solenoid inside a large-radius solenoid, the magnetic field inside the small-radius solenoid is the magnetic field generated by itself plus the magnetic field generated by the large-radius solenoid. (The radius of the solenoids does not have to be with the instensity of the magnetic field):

BT = Bs + Bl

Bs: magnetic fiel of the small-radius solenoid

Bl: magnetic fiel of the large-radius solenoid

Hence:

BT = 2*μo*n*I
