The Pilot of a plane measures an air velocity of 165Km/h south relative to the plane. An observer on the ground sees the plane pass overhead at a velocity of 145 Km/h toward the north.

4. How will you find the volume of an irregularly shaped object that would dissolve in water?

You are driving north on a highway. then, without changing speed, you round a curve and drive east. does your velocity change? do you accelerate? explain.

According to newtons second law of motion, the acceleration of an object equals the net force acting on the object divided by the objects

What is the frequency of a wave having a period Equal to 18 seconds
