Thanks for sharing. The density of the sample
is 5 g/cm³. Do you have a question to ask ?
Answer:
Part a)

Part b)

Part c)

Part d)

Explanation:
Part a)
As we know that the orbital speed of the satellite is given as

now we will have

now we have


now we have


Part b)
Here force between mars and satellite is the gravitational attraction force which is given as



Part c)
Acceleration of satellite is the ratio of gravitational force and mass of the satellite



Part d)
As we know by III law of kepler

here we know that T2 = 8 T1


so we have

as we know that speed is given as

so we can say since radius is orbit becomes 4 times so the orbital speed must be half

Complete question is The frequency of the fundamental of the guitar string is 320 Hz. At what speed c do waves move along that string? wavelength is 40 cm.
Answer:
128 m/s
Explanation:
In case where fundamental frequency is given, the speed with waves travel along the string can be calculated using the following formula:
v = f (2L) where L is the length of the string (L = λ/2)
⇒v= f λ
f = 320 Hz (given)
λ = 40 cm = 0.40 m
Substitute the values:
⇒ v = 320 Hz × 0.40 m= 128 m/s
Answer:
a
Explanation:
it explains the most, and it is the correct theorem
Because they are using all of there energy to apply the force
