Carole is very tired and makes coffee. why would newton say that she must use her hand to pick up the cup? a) the idiom that every action has an equal and opposite reaction applies. b) an object at rest will stay in at rest unless acted upon by an external force. c) acceleration of the object is indirectly proportional to the balanced forces. d) the coffee's inertia accelerates with the force due to the unbalanced forces

Carole is very tired and makes coffee. Newton would say that she must use her hand to pick up the cup, because an object at rest will stay at rest unless acted upon by an external force. (B)

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
