Abeam of π+ particles (mπ = 140 mev/c2) is accelerated to a momentum of pπ+ = 3.1 gev/c in the laboratory frame. a π+ particle decays into a positive muon (mμ = 105 mev/c2) and a muon neutrino (mνμ = 0 mev/c2).

a. what is the energy of the muon in the rest frame of the π+?
b. what is the energy of the muon in the laboratory frame if it is found traveling in the beam direction?
c. what is the energy of the muon in the laboratory frame if it is found traveling at and angle of 250 mrad with respect to the beam direction?

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
