Remember that work (J) = force (N) * displacement (m) An object is tossed 24.3 meters into the air. The applied force is 15.9 N. What is the resulting work?

A. 1.5 j
B. 386.4 j
C.40.2 j
D.8.4 j

What object a collides with object b and bounces back its final momentum is?

Hydrogen atoms are excited by a laser to the =4n=4 state and then allowed to emit. what is the maximum number of distinct emission spectral lines (lines of different wavelengths) that can be observed from this system? 8 6 2 7 4 5 1 3 calculate the wavelength of the 4⟶14⟶1 transition. =λ=

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