Adentist's drill starts from rest. after 3.00 s of constant angular acceleration it turns at a rate of 2.60 x 104 rev/min (a) find the drill's angular acceleration. rad/s (b) determine the angle (in radians) through which the drill rotates during this period rad

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

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
