if it takes 1 second to move from x to y. You haven't specified if x and y are extreme point or x is extreme and y is equilibrium point
I.If both are extreme points the period is T=1*2=2s
f(frequency)=2π/T(period)
f=6.28/2=3.14Hz
II.If x is an extreme point and y is equilibrium
T=4*1=4s
f=6.28/4=1.57Hz
Force on left crate, right crate and truck we need to draw here
First we will write the equation for left crate


Now similarly for right crate

now for truck

Now we know that F = 200 N

now add all three equation



now we will find all tension using this value of acceleration



Answer:
(d) they are transmitted using digital signals
Explanation:
i just did the quiz an got it right
<span>Friction
can help us play tennis, knock down bowling pins, and cook dinner.</span>
Gravity decreases with the square of the distance, so the new force is (20)/(2*2) = 5N.
