Answer:
Due to energy loss while collision ball will not reach to same height while if there is no energy loss then in that case ball will reach to same height
Explanation:
As we know that initially ball is held at height h = 40 cm
So here we can say that kinetic energy of the ball is zero and potential energy is given as

now when strike with the ground then its its fraction of kinetic energy is lost in form of other energies
So the ball will left rebound with smaller energy and hence it will reach to height less than the initial height
While if we assume that there is no energy loss during collision then in that case ball will reach to same height again
Answer:
1) The Newton's law the Hulk is most closely demonstrating is <em>the Third Law of motion</em>
Newton's third law of motion states that action and reaction are equal and opposite.
2) The reason why the Newton's Law the Hulk is most closely demonstrating is the Newton's Third Law of Motion is that according to Newton's Third Law of motion, forces exist in pairs, the action of the Hulk when he leaps upward by pushing against the the Earth (which can be assumed stationary in relation to the Hulk), is equal to the reaction of the Earth, which moves down slightly, away from its initial position.
However, due to the large mass of the Earth, compared to the mass of the Hulk, the downward motion of the Earth due to the reaction force (equal to the force with which the Hulk leaps) is negligibly small, such that the Earth can absorb the Hulk's leap force by reacting mainly locally, at the leap point by forming a crater, while the Earth in general, remains in the same place
Explanation:
Mass & Height above the ground
Answer: A. Frequency
B. Wavelength
Explanation: Electromagnetic waves are waves which can travel through the vacuum. Electromagnetic waves have electrical and magnetic component associated with them.
Electromagnetic waves are arranged in order of increasing frequencies or decreasing wavelengths.
Radio waves, X-rays, and gamma rays are all electromagnetic waves which have different wavelengths and thus have different frequencies. But they all travel with the speed of light.

The order of frequency of given waves : gamma rays > X rays> Radio waves.
The order of wavelength of given waves : gamma rays < X rays < Radio waves.
Answer: d = st
Explanation:
We know that the distance is equal to the rate (speed) times the time
d = st
