Answer:
v=-30 m/s
Explanation:
Using the equation:
v=u+at
v=?
u means initial velocity=0
a=-10 since it is going down we make the acceleration due to gravity negative
t=3
v=0+(-10)(3)
v=-30 m/s
The answer should be all of the above

Answer:
A hydraulic press works on the principle of Pascal's law, which states that when pressure is applied to a confined fluid, the pressure change occurs throughout the entire fluid. Within the hydraulic press, there is a piston that works as a pump, that provides a modest mechanical force to a small area of the sample.
Explanation:
Answer:
A vibration is a repeated back-and-forth or up-and-down motion.
