Answer:
Following are the answer to this question:
Explanation:
In option (a):
- The principle of Snells informs us that as light travels from the less dense medium to a denser layer, like water to air or a thinner layer of the air to the thicker ones, it bent to usual — an abstract feature that would be on the surface of all objects. Mostly, on the contrary, glow shifts from a denser with a less dense medium. This angle between both the usual and the light conditions rays is referred to as the refractive angle.
- Throughout in scenario, the light from its stars in the upper orbit, the surface area of both the Earth tends to increase because as light flows from the outer atmosphere towards the Earth, it defined above, to a lesser angle.
In option (b):
- Rays of light, that go directly down wouldn't bend, whilst also sun source which joins the upper orbit was reflected light from either a thicker distance and flex to the usual, following roughly the direction of the curve of the earth.
- Throughout the zenith specific position earlier in this thread, astronomical bodies appear throughout the right position while those close to a horizon seem to have been brightest than any of those close to the sky, and please find the attachment of the diagram.
Answer:
Battery.
Explanation:
A battery is a device that stores chemical energy, and converts it to electricity. This is known as electrochemistry and the system that underpins a battery is called an electrochemical cell. A battery can be made up of one or several (like in Volta's original pile) electrochemical cells
Answer:
Explanation:
Sum all the forces that are acting on the object and what ever the sum is, is what the net force is.
For example if there is a piece of wood sitting on a table the net force would be the sum of the forces that are acting on it, so the force of gravity (which is negative) + the normal force which would equal zero because they are the same value.
Answer:
The acceleration is 
Explanation:
From the question we are told that
The radius is 
The magnitude of the magnetic field is 
The rate at which it decreases is 
The distance from the center of field is 
According to Faraday's law
and 
Where the magnetic flux 
E is the electric field
dl is a unit length
So
Now 
is the circumference of the circular loop formed by the magnetic field and it mathematically represented as 
A is the area of the circular loop formed by the magnetic field and it mathematically represented as 
So
![E = \frac{r}{2} [ - \frac{db}{dt} ]](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%7Br%7D%7B2%7D%20%5B%20-%20%5Cfrac%7Bdb%7D%7Bdt%7D%20%5D)
Substituting values
The negative signify the negative which is counterclockwise
The force acting on the proton is mathematically represented as
Also 
So
Where m is the mass of the the proton which has a value of 
So
