Ng seismic and translational waves we get the law of michio kaku.
Answer:
A horse pushes the ground in a backward direction. According to Newton’s third law of motion, a reaction force is exerted on the horse in the forward direction. When the horse walks in the forward direction (with the cart attached to it), it exerts a force in the backward direction on the Earth. An equal force in the opposite direction (forward direction) is applied on the horse by the Earth. This force moves the horse and the cart forward. As a result, the cart moves forward.
Answer:
Explanation:
The energy of a particle in one dimensional box is given by :
n is the quantum number
h is the Planck's constant
m is the mass of particle
L is the length of box
If L' = L/2
Energy level is given by :
So, if the same particle is placed in another box of length L/2, the energy should be four times the energy for the first box. Hence, this is the required solution.
