In this lab, you will use a dynamics track to generate collisions between two carts. If momentum is conserved, what variable change would result in a velocity change after a collision? In the space below, write a scientific question that you will answer by doing this experiment. E2020

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
