This is thus because voltage divided by distance determines how strong an electric field is. The field is inversely proportional to this spacing at constant voltage.

More charge can flow via a stronger field, increasing capacitance.

In the simplest terms, the closer two items are near one another, the greater the influence; conversely, the further apart they are, the lesser the influence. As a result, capacitance decreases as spacing increases.

The ratio of the quantity of electric charge held on a conductor to an electric potential difference is known as capacitance. Self-capacitance and mutual capacitance are two concepts that are related to one another.

With the help of Equations of Kinematics, we can say that, both the stones meet at a time t= 4 seconds and they meet at a height of 320 meters from the ground if the speed of the second stone was 100ms⁻¹.

When the body is thrown upwards or downwards it is influenced by gravity and it accelerates and deaccelerates accordingly and its magnitude is equal to the Acceleration due to gravity (g).

Based on this concept, if the body is thrown upwards a = - g (deacceleration), and if the body is dropped downwards a = g(acceleration).

Here in this question, the stone thrown upwards will deaccelerate and the one dropped downwards will accelerate.

So, the Height of the tower=400 meters.

Let the distance traveled by the stone dropped downwards from the top be s₁ and the distance traveled by the stone thrown upwards from the bottom be s₂.

Let the initial velocity of stone dropped downwards be u₁ and the stone is thrown upwards be u₂.

Let the time at which they meet together be t.

Now, using the equation of kinematics,

s=ut+ 1/2gt²

Here, acceleration = a will be equal to the acceleration due to gravity g.

(Take g=10m/s²).

We can write,

s₁=u₁t+1/2 gt²

s₂=u₂t-1/2 gt²

We know that,

s₁+s₂= 400

So, substituting the values of s₁ and s₂

u₁t+1/2 gt² + u₂t-1/2 gt² = 400

As the stone was dropped from rest u₁=0

On further solving,

u₂t=400

Given, u₂= 100ms⁻¹

Hence, t=4 s

Now, s₂= 100(4)-1/2(10)(4²)

=400 - 80

= 320 m

The distance is 320 m from the ground.

The position of an object changes when you move, and this is known as parallax. For instance, if you turn your head a little from side to side while looking at a nearby object, the object will appear to be moving back and forth. 

Sit steady and look at an object while covering your right and left eyes alternately to observe parallax. As you do that, the object will appear to "bounce back and forth." We are able to calculate the distance to surrounding objects thanks to parallax. We frequently employ it in straightforward acts like taking up a pencil. Because stars are so far away, the angle by which their positions change is quite small—only a few hundredths of a degree. The change is so slight that astronomers employ an even smaller measurement of angle called an arc-second, which is equivalent to a sixty-fifth of a sixty-fifth of a degree. So, one arc-second is equal to 1/60x1/60 or 1/3600 of a degree.

Mass is a tangible body in the form of volume of matter. Additionally, it is a measure of the body's inertial, or resistance to acceleration in the presence of a net force The intensity of an object's gravity field to other bodies is also affected by its mass. The kilogram acts as the SI's primary mass unit. Think about the situation where three different scales are holding a marble, a tennis ball, and a bowling ball. The bowling ball would undoubtedly get the highest reading on the scale out of these three. Different planets has different weights and it is because of their gravitational pull while mass is same everywhere in the universe. A body can have mass but still no weight. The formula of Weight is W = mg, where m represents the mass of the body and g is the acceleration due to gravity. Also g depends on the location and the mass of the planet.

We have to find the total time the ball is in the air.

By using the formula, we get,

t = v - u/a

Where t = time to reach the maximum height

v = final velocity of the ball = 0 m/s

u = initial velocity of ball = 18 m/s

a = acceleration due to gravity = -9.8

Acceleration of gravity is taken as negative because the ball is moving in the opposite direction.

t = 0 - 8/-9.8

t = 1.836 sec

Thus, time is taken by the ball to reach the ground again = time taken to reach the maximum height

So, the Total time required for the ball to reach the ground = 2t = 2 × 1.836
