(5 points) using the relation find (λ, t) using the planck formula for blackbody radiation energy density u(v, t) given on lecture. show that the maximum of the radiation energy density u(λ, t) is inversely proportional to the temperature amaxt determine the numerical value of constant b. this is usually called wien displacement law.

When a 5.0kg cart undergoes a 2.2m/s increase in speed, what is the impulse of the cart

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
