The student creates a symmetric wave pulse traveling to the right on the same string. The amplitude of the second pulse is half the amplitude of the original pulse. Which pulse, if either, travels at a higher speed?

a. The higher amplitude pulse.
b. The lower amplitude pulse.
c. Neither, both pulses travel at he sane speed.

Briefly explain your answer.

idk sorry i only needs point for apex

explanation:

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

well clustered together.

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.
