Answer:
s(t)=7t
Explanation:
We are given that
Length of side of square initially=0 cm
Side of square increasing at the rate=7 cm/s
We have to find the formula to express the side length of the square s(in cm) in terms of the number of seconds t.
According to question
Taking integration on both sides then, we get
Substitute t=0 and s=0
Now, substitute the value of C then, we get
s(t)=7t
This is required formula that express the side length of the square s(in cm) in terms of the number of seconds t, since the square's side length began growing.
Use Fnet=ma. Apply it to the vertical components of all the forces acting on the ball and since tension is the same on both wires you should be able to factor it out and solve for it. Picture below

Answer:n contrast, an electromagnetic wave, such as light or radio waves, doesn't need a medium and can travel through empty space. While all electromagnetic waves are transverse, mechanical waves can be transverse or longitudinal, which brings us to our next type of wave.
