What is the temperature of a star (in kelvin) if its peak wavelength is 150 nm (that is, 150 x 10^-9 m)?

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?

If anyonee has done the momentum lab practical in physics can you give me the answers i am s lostt rnn : (

Why does a collision with an airbag cause less damage than a collision with a steering wheel
