Answer:
The fraction of the ball's kinetic energy stored in the spring is 3.6KJoules
Explanation:
Given
Mass of ball =0.5kg
Velocity of ball =120m/s
The kinetic energy stored by the ball is expressed as
K.E=1/2(m*v²)
Substituting our data into the expression we have
K. E=(0.5*120²)/2
K. E=7200/2
K.E=3,600 JOULE
K.E=3.6KiloJoules
Answer:
The minimum difference between the lengths of the two tubes should be 0.385 meters.
Explanation:
As we known that for any two waves to arrive in phase at any point the difference in the path traveled by the waves should be an integral multiple of the wavelength of the wave.
Mathematically we can write:
For the given wave we have
Applying values we get
Thus the minimum difference in the lengths of the tubes can be obtained by putting the value of n = 1
Marine debris is any trash or litter that ends up in a marine environment. This harms wildlife through entanglement, ingestion, and disturbs the habitat of many species of animals. This becomes a global problem when it is a danger to human health. Nails, syringes, and glass can cause harm to people on the beach. On top of that, trash in the waterway increases the amount of chemicals destroying our water quality.
