Answer:
The horizontal force is 106.89 N.
Explanation:
Given that,
Work done = 310 J
Distance = 2.9 m
We need to calculate the horizontal force
Using formula of work done

Where, 

Put the value into the formula



Hence, The horizontal force is 106.89 N.
The correct answer is "3. Both increase"
In fact, the frequency of a vibrating string is given by

where L is the length of hte string, T the tension and

the linear mass density.
We can see that string is made shorter, L decreases, so the frequency f increases. And since the pitch has the same behaviour of the frequency, it increases as well.
Answer
given,
at time t = 10 s moving from left to right speed of particle = 5 m/s
at t = 20 s moving from right to left speed of particle is = 8 m/s
a) acceleration


a = -1.3 m/s²
b) using equation of motion
v = u + at
5 = u - 1.3 × 10
u = 5 + 13
u = 18 m/s
c) v = u + at
0 = 18 - 1.3t

t = 13.85 s
Answer:
No
Explanation:
Because Jupiter, the largest planet in the SS, is right in the middle, and moons like Titan are in the very middle, so it's basically small, then huge, and normal again.
Answer:
c. The magnitude of vertical velocity is at a maximum value.
Explanation:
I think this is correct I'm not entirely sure though
