What is inside a black hole ?​

Answer»

ANSWER:

A BLACK hole is a tremendous amount of matter crammed into a very small — in fact, zero — amount of space. The result is a powerful gravitational pull, from which not even light can escape — and, therefore, we have no information or INSIGHT as to what life is LIKE inside.

__________________________________

More to know about it :

What is at the center of a black hole? At the center of a black hole, it is often postulated there is something called a gravitational singularity, or singularity. This is where gravity and density are infinite and space-time extends into infinity.

• What would happen if you fell into a black hole? ☞It certainly wouldn't be good! But what we know about the interior of black holes comes from Albert Einstein's General Theory of Relativity. ... Fortunately, this has never happened to anyone — black holes are too far away to pull in any matter from our solar system.

One point of similarity between Primary cell and secondary cell

Answer»

Answer:

Primary cell

Primary CELLS have high density and GET DISCHARGED slowly. Since there is no fluid inside these cells they are also known as dry cells. The internal resistance is high and the chemical reaction is irreversible. Its initial cost is cheap and also primary cells are easy to use.

Secondary cell

Secondary cells have low ENERGY density and are made of molten salts and wet cells. The internal resistance is low and the chemical reaction is reversible. Its initial cost is high and is a little complicated to use when COMPARED to the primary cell.

Calculate the amount of work done,when a force of 398.45 N displace a body through 25.25 m, in its own direction​

Answer»

Answer :-

Given :-

  • Force = 398.45 N
  • Displacement = 25.25 m

To Find :-

Solution :-

We know that,

Work done = Force × Displacement

Here, we have both force and displacement. So, by SIMPLE substituting the value in formula, we can find work done -

W = F × S

→ W = 398.45 × 25.25

→ W ≈ 10060.86

Amount of work done, when a force of 398.45 N displace a body through 25.25 m is 10060.86 J.

Length,breadth and height of a cuboid are 5 cm 3cm and 2 respectively Calculate the density of the cuboid if its mass is 90 gmPlz ans fast​

Answer»

ANSWER:

3gm/cm³

Explanation:

Dimensions of the cuboid :

  • 5cm, 3CM, and 2cm.

Volume of the cuboid :

  • (5 × 3 × 2)cm³
  • 30cm³

Density of the cuboid is GIVEN by :

★ p = m/v

Where,

  • m(mass) = 90gm
  • v(volume) = 30cm³
  • 'p' denotes the density.

On substituting the values :

→ 90/30

→ 3gm/cm³

Required answer : 3gm/cm³

-----------------------------------------

Formula used :

★ Density -

  • p = m/v

★ Volume of a cuboid -

  • length × breadth × height.

The focal length of a concave mirror is 17cm. If an object is placed at a distance of 34cm from thepole, then its image will be formed at---​

Answer»

Answer:

Given,

TYPE of Mirror = Concave

Focal Length (f) = -17 cm

Object DISTANCE (u) = -34 cm

[These are negative values because of the CONVENTIONAL rule of concave mirror]

Let's take Image Distance as v cm.

According to the equation,

1/f = 1/u + 1/v

= -1/17 = -1/34 + 1/v

= -1/17 + 1/34 = 1/v

= (-2+1)/34 = 1/v

= -1/34 = 1/v

= -34 cm = v

So, it stands that Image is placed at 34 cm from the pole of concave mirror. It is a real image and is inverted in nature and is as same size as the object. It is formed at the centre of curvature of mirror.

I hope this helps.
