Answer: Correct answer is B = 1.776933×
Explanation:
Given :
Moment of inertia I = 8.26×
kg
Mass of planet m = 6.54×
kg
Also, Planet is solid sphere so that, Moment of inertia is I = 
m
=0.4m
Where R is radius of planet
Putting into calculation
We get,
I = m
8.26× = 0.4×6.54××
8.26×
= 2.616
3.15749235× =
R = 1.776933×
Thus, Correct answer is B = 1.776933×
Answer: 0.16Hz
Explanation:
Given that:
wavelength (λ) = 125 meters
speed (V) = 20 m/s
frequency (F) = ?
Recall that frequency is the number of cycles the wave complete in one second. And its value depends on the wavelength and speed of the wave.
So, apply the formula V = F λ
Make F the subject formula
F = V / λ
F = 20 m/s / 125 meters
F = 0.16 Hz
Thus, the frequency of the wave is 0.16 Hertz.
KE = PE
1/2 m • v^2 = mgh
1/2 • v^2 = gh
V^2/2 = gh
2 • (v^2/2) = 2 • (gh)
V^2 = 2gh
V = sq root (2gh).
Hello there
the answer is hot pot
btw whats the point of haveing a black profile pic if someone else has it -_-
well hope this halps have a great day :p
<span>So we want to know the two main physical quantities that describe the wave. Those are frequency and wavelength. These two quantities are connected via the equation: v=f*L, where v is velocity of a wave, f is frequency of a wave and L is the wavelength of the wave. </span>
