-- You and your partner both get the same job to do:
Each of you gets a pallet of bricks, and you have to
put the bricks up on the bed of a truck, by hand.
Both pallets have the same number of bricks.
The pallet is way too heavy to lift, so you both cut the bands
that hold the bricks, and you lift the bricks from the pallet onto
the truck, by hand, two or three or four bricks at a time.
-- You get your pallet of bricks onto the truck in 45 minutes.
-- Your partner gets his pallet of bricks onto the truck in 3 days.
-- Work = (force) times (distance).
You and your partner both lifted the same amount of weight
up to the same height. You both did the same amount of work.
-- Power = (work done) divided by (time it takes to do the work) .
Your partner took roughly 96 times as long as you took
to do the same amount of work.
You did it faster. He did it slower.
You produced more power. He produced less power.
I think it might just be c because that is the only reasonable option
Answer:
Explanation:
distance between two slit d = 
d = 18.15 x 10⁻⁷ m
Let wave length of light λ
formula for position of first pair of bright spot
Tanθ = λ / d , λ is wave length of light and d is distance between two slit .
Tan 15.4 = 
λ = Tan 15.4 x 18.15 x 10⁻⁷
=5 x 10⁻⁷ m
If θ be the position of next bright spot
Tanθ = 2 λ / d
= 
=
θ = 28.4 degree .
Eating. Your muscles in your arms and mouth use energy to feed itself. Then your body digest the food which also takes energy.
Sleep. When your tired, you don’t have much energy. It is said that you use more energy while your sleeping. But how do you become energized if you were using even more energy than before?
