Base on the experiment, we can deduce that the working principle of most electric generators is based on spinning a permanent magnet near coils of wounded wire.
<h3>What is Faraday's law of electromagnetism?</h3>
Faraday's law of electromagnetism states that the negative rate of change of time (Δt) of the flux of the magnetic field (∅) through a surface is directly proportional to the flux (∅) of the electric field through a surface that has the loop as its boundary.
Electric generators are primarily designed and developed to use the properties of electromagnetism to convert kinetic energy (KE) that is possessed due to motion, into electrical energy. Thus, we can deduce that the mode of operation or working principle of most electric generators is based on spinning a permanent magnet near coils of wounded wire.

Answer:
- Here we use the conservation of momentum theorem.
- m stands for mass, and v stands for velocity. The numbers refer to the respective objects.
- m1v1 + m2v2 = m1vf1 + m2vf2
- Since the equation is perfectly inelastic, the final velocity of both masses is the same. Let’s account for this in our formula.
- m1v1 + m2v2 = vf(m1 + m2)
<u>Let’s substitute in our givens.</u>
(0.002 kg)(700 m/s) + (5 kg)(0 m/s) = vf(0.002 kg + 5 kg)
I assume you are proficient in algebra I, so I will not include the steps to simplify this equation.
Note that I have considered the bullet’s velocity to be in the positive direction,
The answer is vf = 0.280 m/s
Answer:
Power = 21[W]
Explanation:
Initial data:
F = 35[N]
d = 18[m]
In order to solve this problem we must remember the definition of work, which tells us that it is equal to the product of a force for a distance.
Therefore:
Work = W = F*d = 35*18 = 630 [J]
And power is defined as the amount of work performed in a time interval.
Power = Work / time
Time = t = 30[s]
Power = 630/30
Power = 21 [W]
Answer:
θ = 33°
Explanation:
Here, we can use the formula for the total time of flight of a projectile to calculate the launch angle of frog:
where,
θ = launch angle = ?
T = Total time of flight = 0.6 s
g = acceleration due to gravity = 9.81 m/s²
u = launch speed = 5.4 m/s
Therefore,
<u>θ = 33°</u>
Hello,
<span>Batteries have three parts, an anode (-),
a cathode (+), and the electrolyte. The cathode and anode (the positive
and negative sides at either end of a traditional battery) are hooked up to an electrical circuit. The chemical reactions in the battery causes a build up of electrons at the anode.
Hope this helps.
