What can we say about microwaves

waves on the electromagnetic spectrum?

if two people are pulling aganst each other with forces of 200 N and 230N it is called what kind of force?

A train slows down from 34 m/s to 4 m/s in 60 seconds. what is it's acceleration?

Consider a 4-mg raindrop that falls from a cloud at a height of 2 km. When the raindrop reaches the ground, it won't kill you or even bruise you because its terminal velocity is just 10 m/s.

What is the dimension of magnetic flux

A block lies on a horizontal frictionless surface. A horizontal force of 100 N is applied to the block giving rise to an acceleration of 3.0 m/s2. (a) Determine the mass of the block.

Part of the solar radiation entering the atmosphere about ___ actually reaches the earth's surface

A 36.5 kg box initially at rest is pushed 4.30 m along a rough, horizontal floor with a constant applied horizontal force of 150 N. If the coefficient of friction between box and floor is 0.300, find the following.

3 In a television tube, an electron starting from rest experiences a force of 4.0 * 10-15 N over a distance of 50 cm. The final speed of the electron is (do not worry about relativistic effects) :

Detail some of the anthropogenic changes to Earth's climate and their potential impact on life.

I have completed 40 minutes of exercise today and will enter a short description in the course Activity Log. True or False
