Answer:
It decreases by a factor of 4
Explanation:
The gravitational force between two masses is given by

where
G is the gravitational constant
m1, m2 are the two masses
r is the separation between the two masses
In this problem, the distance between the masses is doubled, so
r' = 2r
Substituting into the equation, we see that the new force is

So, the force decreases by a factor of 4.
Answer:
0.000507 kg/m
Explanation:
L = Length of string
T = Tension
= Mass density of string
E denotes the E string
D denotes the D String
Frequency is given by

So


The mass density of the E string is 0.000507 kg/m
Answer:
1 Watt
Explanation:
Power (P) = w / Δt
w = work done
Δt = change in time
Power (P) = 60kg / 60 seconds
Power (P) = 1 Watt
<u><em>Answer:</em></u>
<u><em>Explanation:</em></u>
<em> </em><em> V= V* T</em>
<em>V= 116m /s * 10s</em>
<em>V= 1,160 m</em>
