The electric field at any point in the region between the conductors is proportional to the magnitude Q of charge on each conductor. It follows that:
"The potential difference Vab between the conductors is also proportional to Q"
If we double the magnitude of charge on each conductor, the charge density at each point doubles, the electric field at each point doubles, and the potential difference between conductors doubles; however, the ratio of charge to potential difference does not change. This ratio is called the capacitance C of the capacitor:
Given that:
and
Lastly, the capacitance is given by:
Answer: Car collide with man
Explanation:
Given
Speed of car is 
Distance of the man from the car is 
Reaction time 
Rate of deceleration 
Distance traveled in the reaction time 
Net effective distance to cover 
Distance required to stop the car
Require distance is more than that of net effective distance. Hence, car collides with the man.
Any ride that oscillates back and forth or moves only in a complete circle utilizes periodic motion.
Hello!
We can use Faraday's Law of Electromagnetic Induction to solve.
ε = Induced emf (4.08 V)
N = Number of loops (?)
= Magnetic Flux (Wb)
t = time (s)
**Note: The negative sign can be disregarded for this situation. The sign simply shows how the induced emf OPPOSES the current.
Now, we know that 
is analogous to the change in magnetic flux over change in time, or 
, so:
Rearrange the equation to solve for 'N'.
Plug in the given values to solve.
**Rounding up because we cannot have a part of a loop.
Answer:
Beta particle
Explanation:
If an alpha particle and a beta particle have the same energy, beta particle will penetrate farther into an object than alpha particle because;
1. In air, beta particles can travel a few hundred times farther than alpha particles.
2. Beta particles have more penetrating power than alpha particles.
3. Alpha particle can be absorbed or stopped by an inch or less 1-2 centimeters of air or a thin piece of tissue while beta particles can be stopped or absorbed by a thin layer of Aluminium.
4. Alpha particles loose all of their energies in a small volume easily that beta particles.
5. Beta particles can traveled a longer distance between 2-3 meters at a speed nearly equal to that of light than alpha particles which travel a distance between 2-4 cm at a speed approximately five percent the speed of light.
