Answer:
Sound energy is produced when an object vibrates. The sound vibrations cause waves of pressure that travel through a medium, such as air, water, wood or metal. Sound energy is a form of mechanical energy.
Explanation:
As we know that the formula of kinetic energy will be
![KE = \frac{1}{2} mv^2](https://tex.z-dn.net/?f=KE%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20mv%5E2)
now here we know that
m = 2 kg
v = 1 m/s
so from the above equation we have
![KE = \frac{1}{2}(2)(1^2)](https://tex.z-dn.net/?f=KE%20%3D%20%5Cfrac%7B1%7D%7B2%7D%282%29%281%5E2%29)
![KE = 1 J](https://tex.z-dn.net/?f=KE%20%3D%201%20J)
The acceleration due to gravity on Earth is 9.8 m/s per second.
Because although they cannot see it, they can see it's influence on objects that can be seen, and it's effects.
Answer:
e. The net magnetic flux in this case would be equal to zero.
Explanation:
As per Gauss law of magnetism we need to find the net magnetic flux through a closed loop
here we know that net magnetic flux is the scalar product of magnetic field vector and area vector
so here we have
= net magnetic flux
since we know that magnetic field always forms closed loop so if we find the integral over a closed loop
then in that case the value of the close integral must be zero
so correct answer would be
e. The net magnetic flux in this case would be equal to zero.
