Answer:
At the highest point and at the lowest point the velocity of the mass hung on a spring = 0
Explanation:
Simple Harmonic Motion ( S.H.M) : Simple harmonic motion can be defined as a type of motion were a body vibrates or moves to and fro along a straight line under the influence of a force, so that the acceleration of the body towards a fixed point (equilibrium position) is proportional to its distance or displacement from that point. Examples of bodies undergoing simple harmonic motion are
<em>⇒ The motion of a mass hung on a spring.</em>
<em>⇒ The motion of a simple pendulum</em>
<em>⇒ The motion of a loaded test - tube in a liquid.</em>
Motion of a mass hung on a spring:When a mass is hung to one end spring and other end is firmly clamped to a rigid support.(i)When the mass is in motion, (ii)it pulled down to its lowest point, passes through it equilibrium position (iii) goes to its highest point.
<em>(1) At the lowest and the highest point during the motion of a mass hung a spring, the velocity = 0</em>
<em>(2) At the equilibrium point or unstretched position the velocity is maximum</em>

The answer is , n<span>o, because there are not the same number of molecules in the product side as in the reactant side.
The law of conservation of matter says that the system remains the same throughout. The number of atoms, mass and energy must stay constant. If you look at your figure there are more white atoms on the left side than the right, this means that there was a loss and this should not be the case.

Answer:
velocity =displacement/time
and speed =distance/time
Answer:
2649600 Joules
Explanation:
Efficiency = 40%
m = Mass of air = 92000 kg
v = Velocity of wind = 12 m/s
Kinetic energy is given by
The kinetic energy of the wind is 6624000 Joules
The wind turbine extracts 40% of the kinetic energy of the wind
The energy extracted by the turbine every second is 2649600 Joules
