Imagine that you're loading a pickup truck with bags of groceries. you notice that the smaller the weight you attempt to lift, the quicker you can lift it. however, you also notice that there is a limit to how quickly you can lift even very small weights, and that above a certain weight, you can no longer lift the weight at all. the detailed relationship between the contraction velocity of a muscle (the speed with which you can lift something) and the weight you are attempting to lift, is known as hill’s law.
based on this description, which of the following graphs of velocity vs. force is a possible representation of hill's law?
a. a
b. b
c. c
d. d
e. e

photocells convert light energy to electricity

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
