A wave produced by an earthquake appears in the diagram below.
Wave motion
A second wave leaves the center of an earthquake at the same time. The second wave is a longitudinal wave. After 10 seconds, will the two waves travel the same distance?
Yes, because both waves are longitudinal waves.
Yes, because all waves travel at the same speed in similar mediums
No, because only one type of wave can travel through a medium at a time.
No, because transverse waves travel at different speeds than longitudinal waves,

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
