Two satellites orbit the earth in stable orbits. Satellite a is three times the mass of satellite b. Satellite a orbits with a s

aleksklad [387]

Answer:

Radius of satellite b will be smaller than the radius of satellite a.

Explanation:

m = Mass of satellite

v = Velocity of satellite

r = Radius of satellite orbit

Equating centripetal force and Gravitational force

$\frac{mv^2}{r}=\frac{GmM}{r^2}$

$\\\Rightarrow \frac{v^2}{r}=\frac{GM}{r^2}$

$\\\Rightarrow v^2=\frac{GM}{r}$

$\\\Rightarrow v=sqrt{GM/r}$

It can be seen that the velocity is inversely proportional to the radius and the mass of the satellite does not have any effect.

This means that in order for v to increase the radius has to decrease

Here, $v_b>v_a$

So, the radius of satellite b will be smaller than the radius of satellite a.

The electric field strength between a parralel plate is E. The separation of plate is doubled and potential difference between t

grin007 [14]

Answer:

The new electric field strength is 2E

Explanation:

The electric field between parallel plated can be calculated from the formula

E = V/d

Where E is the Electric field strength

V is the potential difference between the plates

and d is the separation between them

In the first instance where the electric field strength between the parallel plates is E. Let the potential difference (V) be V₁ and the separation between the plates (d) be d₁.

∴ E = V₁/d₁

Now, from the question

The separation of plate is doubled, that is, d = 2d₁

and potential difference between the plate is increased by factor of 4, that is, V = 4V₁

Then,

From E = V/d

Let the new electric field be E₂

Then,

E₂ = 4V₁/2d₁ = 2V₁/d₁

E₂ = 2(V₁/d₁)

E₂ = 2E

Hence, the new electric field strength is 2E.

A burning candle is covered by a jar as shown in the picture. The whole arrangement has a mass of 500 g. What will be the approx

Anna11 [10]

The law of conservation of matter is that the amount of matter you begin the reaction with is the amount you will end up with. So if you start with 500g of matter, when you burn the candle you will also have 500g of matter to end with. SO D is your answer
