''Joules'' are ''watt-seconds'', so divide the joules by the number of seconds to get the rate of power- i get 3,333 watts. Now divide that by the voltage to get the current- I get 15.15 amps
Hold on and let's discuss this realistically.
Because of gravity, there are two forces between the Earth and me. One draws me toward the Earth. The strength of that force is what I call my "weight". The other force draws the Earth toward me, and has the same strength.
The strength of these forces depends on the masses of the Earth and me. If the strength just tripled, that means that at least one of us just picked up a lot more mass. If the Earth suddenly became three times as massive, then the weight of everything and everybody on it would suddenly triple, and I'm pretty sure it would be the end of all of us before too long.
If it was only MY mass that suddenly tripled, that would mean that I had gone tearing through my house and the neighbour's house, eating everything in sight including the 2 couches, 3 dogs, and 6 TVs. Naturally, just as you would expect, my weight changed from 207 to 621, and my skin is stretched really tight.
ooohhh
The speed of the particle when it enters the magnetic-field region is 120,000 m/s.
<h3>
Speed of the particle</h3>
Magnetic force on the particle is given as;
F = qvB
where;
- q is magnitude of the charge
- v is speed of the particle
- B is magnetic field strength
From Newton's second law, force on an object is given as;
F = ma
where;
- m is mass of the particle
- a is acceleration
ma = qvB
v = ma/qB
v = (3 x 10⁻² x 12)/(3 x 10⁻⁶ x 1)
v = 120,000 m/s
Thus, the speed of the particle when it enters the magnetic-field region is 120,000 m/s.

Elastic energy is potential energy and mechanical energy is kinetic energy.
Many times, elastic energy is a consequence of mechanical energy. When energy is transferred to an object through mechanical energy, it can often displace or deform the object. This stored energy because of the deformation is called elastic energy.
Answer:
2.3687599 m/s
0.91106 m/s
0.617213012 J
Explanation:
f = Frequency =
A = Amplitude = 0.13 m
k = Spring constant
m = Mass of object = 0.22 kg
Angular velocity is given by
Velocity is given by
Speed when it passes the equilibrium point is 2.3687599 m/s
Frequency is given by
x = Displacement = 0.12 m
In this system the energies are conserved
The speed when it is 0.12 m from equilibrium is 0.91106 m/s
The energy in the system is given by
The total energy of the system is 0.617213012 J
