The amplitude is equivalent to the coefficient of the sine function, so:
Amplitude = 1
The time period of a Sin(x) = 2π
The time period of Sin(4x) = 2π/4 = π/2
The period is π/2
If you are talking about gravitational potential energy, then the ONLY way to either increase OR decrease it is to raise or lower your height. The higher you are off the ground the greater your PE, the closer you are to the ground, the lower your PE
Pascal's principle
Explanation:
Pascal principle states that "a change in pressure at any point in a fluid in a closed container is transmitted equally and unchanged in all directions throughout the fluid".
Pascal principle is used to solve for the pressures in fluid.
- Hydraulic lift works on pascal principle.
- Pascal principle suggests that a pressure change in an enclosed fluid is transmitted uniformly to all of its parts.
- The principle was established by Mathematician Blaise Pascal

187500 Joules of work must be done to the 3000 kg car to change its speed from 10 m/s to 15 m/s.
Explanation:
Work is the measurement of the force on an object that overcomes a resisting force (such as friction or gravity) times the distance the object is moved. If there is no distance, there is no work, no matter what the effort.
Work done = Force * displacement
When you apply enough force on an object to overcome a resistive force, such that you move that object, you are doing work on that object. There is a relationship between that work and mechanical energy.
When an object is accelerated, you are doing work against inertia, such that the work equals the change in kinetic energy of the object.
Work done = Change in K.E
In the given case:
mass = m = 3000 kg
initial velocity = v₁ = 10 m/s
final velocity = v₂ = 10 m/s
Work = W = (1/2)m(v₂)² - (1/2)m(v₁)²
