I think it's potassium, but i'm not sure
Call the capacitance C.
<span>Note the energy in a capacitor with voltage V is E =½CV². </span>
<span>Initial energy = ½C(12)² = 72C </span>
<span>40% of energy is delivered, so 60% remains.in the capacitor. </span>
<span>Remaining energy = (60/100) x 72C =43.2C </span>
<span>If the final potential difference is X, the energy stored is ½CX² </span>
<span>½CX² = 43.2C </span>
<span>X² = 2 x 43.2 = 86.4 </span>
<span>X = 9.3V</span>
Answer:600N/m
Explanation: Given ;
Applied force(F) = 180N
Total extension (l) = 30cm =0.30m
Spring constant(K) =?
From Hooke's law
F= kx
therefore k= F/x
k = 180N/0.3m
600N/m
Answer: faster
Explanation:
Given
hammer is dropped from a height of 12 ft on the surface of the moon
Here, the potential energy is converted into kinetic energy
That is velocity is a function of the square root of height. The more the height, greater is the velocity.
So, the hammer hits the ground faster .
The appropriate response is foreshortening. It is the visual impact or optical deception that makes a protest or separation seem shorter than it really is on account of it is calculated toward the watcher. Also, a question is regularly not scaled equitably: a circle frequently shows up as an oval and a square can show up as a trapezoid.
