Answer;
=32.15 meters
Explanation;
Use the formula
s= ut+ 0.5 a (t)^2 to find out 's'
where s= distance traveled
u=initial velocity which is zero in this case
t= time taken to travel 's' distance
a=acceleration (due to gravity on moon i.e 1.62 m/s^2 )
Therefore;
S = 0.5 * 1.62 * 6.3 * 6.3
= 32.1489 meters
Thus; the crater is 32.15 meters deep.
Answer:
quantity A is mass and quantity B is wright
Answer:
The phase difference between waves 31.7 rad
Explanation:
Given :
Wavelength 
m
Separation between two slit 
m
Angle 
25°
From the formula of phase difference,
Where 
phase difference
rad
Therefore, the phase difference between waves 31.7 rad
