An object accelerates uniformly in a straight line at a rate of 0.250 m/s2 from 1.50 m/s to 4.00 m/s. How far did the object travel during this acceleration in units of meter? (don't write the unit

The girl has a speed of 7 m/s at the bottom of the ramp. Calculate the kinetic energy of the girl at the bottom of the ramp use the equation kinetic energy = 0.5 x mass x (speed)²

Calculate the number of Bohr magnetons per atom of iron, given that the saturation magnetization Ms=1.70×106 A/m, that

Create a short video demonstrating Newton’s third law, using an example not presented in this activity (for instance, you cannot use the example of a pop can sitting on a table). Be creative!

In your video:

Identify the two objects exerting the action and reaction forces.

Describe how the reaction force affects the first object, and how the reaction force affects the second object.

If your objects are in motion, demonstrate the motion.

While the video does not have to include you narrating, at some point, please show yourself in the video.

If your video features a friend or family member, or even a stranger, be sure to get their permission first, before using the video.

a) Two parallel plates with 0.025m width and 0.05m length are placed vertically such that the field intensity E between them is 11kN/C directed upward. Find the charge of each plate.

b) A metal sphere with radius 0.035m has a charge 5 x10^-6C at its surface. Find the electric field E at the surface, the field at 0.02m out of the surface and the field at 0.02m within the surface.
