μ = F/N
Answer:
False. Its your body, you do what you want. Wanna lose weight? Then do some reasearch. Wanna keep how body how it is? Then keep it. Its your body
Explanation:
Since P=E/t,
where P=power (W),
E=energy (J) and
t=time (s).
Just rearrange this formula to obtain E=P*t=5400*640=3456000 J.
Energy and work are very related since energy is defined like the ability of doing work. Actually work is also measured in J so the answer is the one above.
Work = 3456000 J
Answer:
200 m
Explanation:
Path difference of waves from A and B = 100m
For destructive interference
Path diff = ( 2n+ 1 ) λ / 2
100 = ( 2n+ 1 ) λ / 2
λ = 200 / ( 2n+ 1 )
For maximum λ , denominator should be smallest which is possible for
n =0
λ = 200 / 1
= 200 m
ITS 20,000 from the test that i took and got it right.hope this helped..
