Answer:
d = .076 m
Explanation:
The time for frog A can be calculated from equation of motion
where v_f is final velocity, a is acceleration due to gravity
so from given data we have
t = 0.112 sec
Now we will use that time for frog B
(Note its positive)
For the displacement
d = .076 m
The last one. Opposites attract while similar ones repulse each other so all forces are pushing them apart
That would be false
Hope this helps :)
Properly input current above 40 voltage or 100 for example elecrical fan machine is used to perform a task, work output is always more than work
Energy at top = U = mgh = 40 * 9.8 * 12 = 4704 J
Energy at bottom = 1/2 mv² = 1/2 * 40 * 10² = 4000 / 2 = 2000 J
Energy Lost = Final - Initial = 4704 - 2000 = 2704 J
In short, Your Answer would be 2704 Joules
Hope this helps!
