I'm going to say that is it true because when electromagnetic waves occurs when a electric and magnetic field vibrates.
Hope this is correct and is what you are looking for!<span />
Answer:
Explanation:
As we know that area of the circle at any instant of time is given as
now in order to find the rate of change in area we will have
here we know that
rate of change of radius is given as
radius of the circle is given as
now we have
It is about density. The less dense object will tend to float when put into the water. For example, oil is denser than water so the result of the mixture would make oil float. Sinking objects would only mean that it has an equal or greater mass than water.
Answer:
'A ball is thrown straight up with an initial speed of 12 m/s_ What are the velocity and acceleration when it is at the top of its trajectory? Select all apply. v=12 mls a = 0 v =-12 mls a = 9.8 m/s2 Oa=-9.8 m/s2'
Explanation:
I look it up
Hope this helps
The net force on the object is zero, so it has no acceleration. It moves in a straight line and at a constant speed (which may be zero).
