Answer:
1) 0.51 seconds.
2) 1.45 m/s.
Explanation:
given, height from which cat falls = 1.3 m
we know that, s = ut +
at².
here if we consider cat moment only in downward direction,
intial velocity of cat in downward direction , u = 0.
so, time, t =
.
⇒ t =
= 0.51 seconds.
t = 0.51 seconds.
now, consider cat moment only in forward direction
s = ut , since acceleration is zero in forward direction
⇒ u =
.
so, u =
= 1.45 m/s .
I'm assuming we're applying the standard Integral form of the calculation of work. The solution is provided in the image.
Answer:
PE = (|accepted value – experimental value| \ accepted value) x 100%
Explanation:
B. is the answer.
C is not correct because the light is actually reflected off of an opaque object.
