1. All electromagnetic waves can undergo reflection. a. State three properties common to all electromagnetic waves. b. Microwaves produced by a source travel at a speed of 3.0 x 10^8 m/sec and frequency of 1.5 x 10^10 Hz in vacuum. Calculate the wavelength of these microwaves. Mark the position of the waves in the following fig:

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s. assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.

If you let go of the notebook after lifting it, will it move? how?

What are the differences and relationships between speed, velocity, and acceleration
