Avery long stick ruled with meter markings is placed in empty space. a spaceship of rest length l = 100 m runs lengthwise alongside the stick. two space travelers equipped with knives and synchronized watches station themselves fore and aft. at a prearranged time, each reaches through a porthole and slices through the stick. if the relative velocity of the stick and ship is v = (4/5)c, how many meter marks are on the cut-off portion of the stick? do the calculation first in the frame of the ship, and then do the calculation over in the frame of the stick. in each case, draw careful pictures.

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?

What are similarities and differences between refraction, reflection, diffraction and absorption?

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
