Suppose that a conducting sphere is charged positively by some method. The charge is initially deposited on the left side of the

sphere. Yet because the object is conductive, the charge spreads uniformly throughout the surface of the sphere. The uniform distribution of charge is explained by the fact that ____.

Answer:

electrons will migrate untill there is uniform distribution of  charge .

and sphere became uniformly charged

Explanation:

as conducting sphere is charged positively it is given . the left side of sphere is charged positively . there is negative charge on the left side that will be attracted by positive charge of right side .

therefore electrons from left side will start migrate towards right side due to attraction of positive charge of right side .

therefore electron will start migrate uniformly .

electrons will migrate untill there is uniform distribution of  charge .

and sphere became uniformly charged

b) A satellite is in a circular orbit around the Earth at an altitude of 1600 km above the Earth's surface. Determine the orbita
asambeis [7]

Explanation:

The orbiting period of a satellite at a height h from earth' surface is

T=2πr32gR2

where r=R+h.

Then, T=2π(R+h)R(R+hg)−−−−−−−−√

Here, R=6400km,h=1600km=R/4

T=2πR+R4−−−−−−√R(R+R4g)−−−−−−−−−⎷=2π(1.25)32Rg−−√

Putting the given values,

T=2×3.14×(6.4×106m9.8ms−2)−−−−−−−−−−−−√(1.25)32=7092s=1.97h

Now, a satellite will appear stationary in the sky over a point on the earth's equator if its period of revolution around the earthh is equal to the period of revolution of the earth up around its own axis whichh is 24h. Let us find the height h of such a satellite above the earth's suface in terms of the earth,'s radius.

Let it be nR.Then

T=2π(R+nR)R(R+nRg)−−−−−−−−−−√

=2π(Rg)−−−−−√(1+n)32

=2×3.14(6.4×106m/s9.8m/s2)−−−−−−−−−−−−−−−⎷(1+n)32

(5075s)(1+n)32=(1.41h)(1+n)32

For T=24h, we have (24h)=(1.41h)(1+n)32

or (1+n)32=241.41=17

or 1+n(17)23=6.61

or n=5.61

The height of the geostationary satellite above the earth's surface is nR=5.61×6400km=6.59×104km.

Why 2 objects don't attract each other with gravitational force? Explain with newton's law of universal gravitation. PLS NO SEAR
Tema [17]

Answer:

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

Two pro baseball players of the same height are testing how far they can throw. One players throws the ball at a 40.0 degrees an
Viktor [21]

Answer:

The  distance traveled by the ball before it lands in the other player's glove is 130.96 m.

Explanation:

Given;

angle of projection of the ball, θ = 40⁰

initial velocity of the ball, u = 36.1 m/s

The distance traveled by the ball before it lands in the other player's glove is the range of the projectile, calculated as follows;

R = \frac{u^2 sin(2\theta)}{g} \\\\R= \frac{36.1^2 \times sin(2\times 40)}{9.8} \\\\R = \frac{36.1^2 \times sin(80)}{9.8} \\\\R = 130.96 \ m

Therefore, the  distance traveled by the ball before it lands in the other player's glove is 130.96 m.
