Which of the following statements regarding the motor unit is true:

a. each motor unit can consist of a different number of muscle fibers.
b. all muscle fibers of one particular motor unit are always the same fiber type.
c. a muscle can be composed of a different number of motor units.
d. each muscle fiber can be innervated by only one motor unit.
e. all are correct.

the largest known star in the universe is uy scuti, a hypergiant with a radius around 1,700 times larger than the

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.

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
