If F = force, which equation illustrates the Law of Conservation of Momentum? A) F1 = F2
B) F1 = - F2
C) - F1 = -F 2
D) F1 + - F2 = F3

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

we need to know the time interval during which the force acts. impulse of force = momentum change

connect the batteries in series and hope

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
