A body of mass 50kg explodes and splits into three pieces, the first piece has mass of 10kg and velocity of [ -18 23 ]m/s and the second piece has mass of 18kg and velocity of [ 25 -18 ]m/s what id is the velocity of the piece.

A1kg cart slams into a stationary 1kg cart at 2 m/s. the carts stick together and move forward at a speed of 1 m/sl. determine whether kinetic energy was conserved in the collision. use the law of conservation of energy to explain the collision

While listening to operatic solos, musicians process the lyrics and the tunes in separate brain areas. this most clearly illustrates the functioning of different

In which situation has the independent variable for the experiment been changed? check all that apply. changed from counting the number of duckweed at day 0 and day 14 to counting them every day changed from testing duckweed growth in beakers to testing duckweed growth in large outdoor tanks changed from testing the effect of ph on duckweed growth to testing the effect of light levels on duckweed growth changed from testing the effect of acid ph on duckweed growth to testing the effect of basic ph on duckweed growth
