Answer:
20.35m per minute
Or
1,221.43 per hour
100/5=20
200/7= 28.57
50/4= 12.5
20+28.57+12.5= 61.07
61.07/3= 20.35m per minute
Or
20.35 x 60= 1,221.43m per hour
You have learned your lesson well, Suhay. Your statement is correct.
The light rays from the fish BEND when they flow out of the water into the air. But our primitive brain still believes that the light rays flow STRAIGHT from the fish. The result is that the fish does not APPEAR to be at that place where it really is.
The correct choice is
A. III and IV only
according to newton's second law, force is directly proportional to the acceleration of the object and vice versa and is given as
F = ma
where F = net force on the object
m = mass of the object
a = acceleration of the object
when an unbalanced force acts on an object, the object experiences acceleration. we know that acceleration is nothing but the time rate of change of velocity. hence object experience change in velocity. The velocity can change either by a change in speed or by change in direction of motion.
Answer:
28 m/s
Explanation:
vf^2=vi^2+2a(delta y)
=sqrt(2* -9.8 m/s^2* -40 m)
=28 m/s
