Answer:
B
Explanation:
Versatility is ability to adapt or be adapted to many different functions or activities.
Answer:
Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium. The human ear detects sound waves when vibrating air particles vibrate small parts within the ear.
In many ways, sound waves are similar to light waves. They both originate from a definite source and can be distributed or scattered using various means. Unlike light, sound waves can only travel through a medium, such as air, glass, or metal. This means there’s no sound in space!
Explanation:
Answer:
25 degrees
Explanation:
The angle of incidence equals the angle of reflection
For this case we have that by definition, the average power is given by:
Where:
W: It is the work done
t: It's time
According to the data we have to:
So:
Answer:
Answer:
400 N
Explanation:
Due to action-Reaction, the wall pushes back on the person with a force of equal magnitude and in opposite direction to the force exerted by the person.
So the magnitude must be also 400 N.
