Answer: The tidal forces exerted by the moon are directly associated with the earth's rotation. Due to the strong gravitational pull of the moon, the tidal bulging appears on both the sides on earth and these are region of high tide, and there is gradual rise and fall of sea level.
Because of these tidal effect, the earth is able to rotate only once in each of the orbital period.
Answer:
The phenomenon known as "tunneling" is one of the best-known predictions of quantum physics, because it so dramatically confounds our classical intuition for how objects ought to behave. If you create a narrow region of space that a particle would have to have a relatively high energy to enter, classical reasoning tells us that low-energy particles heading toward that region should reflect off the boundary with 100% probability. Instead, there is a tiny chance of finding those particles on the far side of the region, with no loss of energy. It's as if they simply evaded the "barrier" region by making a "tunnel" through it.
Explanation:
Answer:
I believe it's sound energy.
Explanation:
Sound can move through air, whereas electric and radiant energy don't have to.
The speed of an object at rest is 0 m/s. We can use logic to figure this out. Hope this helps!
Answer:
False.
Explanation:
Yes the magnitude of a vector is always positive , but a vector consists of
when two vectors are added their direction may be opposite to each other For example-
,
then their resultant
This resultant vector's x and y component equal to y and x component of vector b so its magnitude will be equal to magnitude of vector b.
Therefore, the resultant magnitude not necessary equal to the magnitude of either vector.
