Answer:
B. 2. A baseball was hit by a bat and now flying through the air.
Explanation: A baseball that is hit by a bat has a larger velocity, due to this the amount of kinetic energy is high.
A wave period is the time it takes to complete one cycle

Answer:
Vrel_jon's = 15 [m/s] to the right
Explanation:
Relative velocity is defined as the relative motion between two bodies, taking into account the directions of motion.
Relative velocity is defined as the relative motion between two bodies, taking into account the directions of motion. The relative velocity is defined as the algebraic sum of the velocities, if the movements are opposite the vectors are subtracted, as will be done below.
Vrel = 20 - 5 = 15 [m/s]
A person watching Jon sees him moving to the right at a speed of 15 [m/s]
Solution :
Given data is :
Density of the milk in the tank, 
Length of the tank, x = 9 m
Height of the tank, z = 3 m
Acceleration of the tank, 
Therefore, the pressure difference between the two points is given by :

Since the tank is completely filled with milk, the vertical acceleration is 

Therefore substituting, we get




Therefore the maximum pressure difference in the tank is Δp = 47.87 kPa and is located at the bottom of the tank.
