Answer:
Option C
Explanation:
Kinetic energy is the energy that the body possesses by virtue of its motion.
The formula for Kinetic energy is given by 
Using this formula let us find kinetic energy for the bodies given and find out which is the greatest
A) KE = 
B) KE =
C) KE = 
D) KE = 
Comparing these we find that 9mv^2 is the highest.
Hence option C is the answer.
Answer: Globalization is the process of interaction and integration among people, companies, and governments worldwide.
Explanation:
Answer:
Explanation:
Yes she is doing work. With or without the groceries, she is still doing work. She does more work with the groceries than without because Work is defined by F which is defined by mass. The mass increases with the groceries.
The work done is against the force of gravity.
All the spheres interact with other spheres. For example, rain (hydrosphere) falls from clouds in the atmosphere to the lithosphere and forms streams and rivers that provide drinking water for wildlife and humans as well as water for plant growth (biosphere). ... Flooding rivers wash away soil.
Answer:
one-fourth of the wavelength
Explanation:
When any wave move form its equilibrium to level to the crest then it covers one-fourth of the wavelength. The waves goes twice to its extreme position, once at the crest and one at the trough.
The midway between the crest and trough is the equilibrium position of the wave. The wave in one cycle covers 360° phase. Here when the wave goes from equilibrium to the crest then the wave covers 90° of the phase.
The given time multiplied by 4 gives the time period of the wave.
