Two slits are 0.135 mm apart. A mixture of red light (λ= 445 nm) falls on two slits. If an interference pattern is produced on a screen 2.8 m away, find the distance between the 1st red fringe and the 1st blue- violet fringe.

If the speed of a particle triples ,by what factor does its kinetic energy increase?

A0.580-kg rock is tied to the end of a string and is swung in a circle with a radius of 0.500 meters. the velocity of the rock is 4.50 m/s. what is the centripetal force acting on the rock? 15.5 n 5.22 n 69.8 n 23.5 n

Refer to your lab guide and review the data in table b to complete each statement. the mass of g1 + g2 after the collision kg. the velocity of g1 + g2 after the collision m/s. the momentum of the combined gliders after the collision kg · m/s.
