Answer:
B) -1m/s^2
Explanation:
Final speed = 0 m/s
Initial speed = 5m/s
Time taken for it to come to rest(0m/s) = 5
then use the formula;
[v = u + at],where v is the final speed..u is the initial speed..t is time taken for it to come to rest and a is the acceleration
; 0 = 5 + 5a
; -5 = 5a
;Acceleration = -1 m/s^2
The pull of the moon on Earth's tidal bulge is causing The moon to slowly move farther away from the Earth. Hope that helps.
Answer:
it will be zero degree
the angle of reflection is zero on hemisphere sides and angle of i is equal to angle of r
Answer:
is in units of 
is in units of 
is in units of 
Explanation:
We have the following expression:
Where:
is the distance, hence its unit is (meters, assuming we are using the International System of Units)
is the time, hence its unit is 
(seconds)
So, the expression is rewritten as:
Since the left side of the equation is in meters, the right side must be in meters as well.
In addition, in the right side we have terms that have to added, this means each term must be in meters:
- For the first term must be in units of in order to have meters.
- For the second term must be in units of in order to have meters.
- For the third term must be in units of in order to have meters.
I could only tell you if i knew what the figure looked like
