A car of mass 1000 kg which has a velocity of 10 m/s east collides at a crossroads with a car of mass 800 kg which has a velocity of 5.0 m/s north. If the cars lock together after the collision,
calculate their velocity immediately after the collision. How much kinetic energy is converted to
other forms in the collision? Neglect external forces. (Calculate Total Kinetic energy before and
after)​

The plum pudding model of the atom state that ?

An initially unpolarized light if intensity 500 w/m^2 passes through four polarizers. the transmission axis between adjacent polarizers is 45∘. what percentage of the initial intensity is transmitted by the system?

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
