Cody's car accelerates from 0m/s to 45 m/s northward in 15 seconds. What is the acceleration of the car?

An electron is placed at rest in the middle of this electric field (due to a parallel-plate capacitor). There is a vacuum between the plates. What can we say will happen to the electron while it is in this electric field

Two carts on a straight track collide head on. The first cart was moving at 3.6 m/s in the positive x direction and the second was moving at 2.4 m/s in the opposite direction.

Identify the type of force described (contact or noncontact): The force that is exerted when a shopping cart is pushed: The force that causes a metal ball to move toward a magnet:

An electron is held at a distance from a stationary, positively charged object. If the electron is released, what energy change will take place? A. Electric potential energy into kinetic energy ) B. Kinetic energy into electric potential energy C.

How is it that an electric bulb lights up as soon as we turn the switch on if the drift speed is 1mm / s^2

Nikolas, the fire extinguisher, and the skateboard have a combined mass of 50 kg. What force would the fire extinguisher have to produce to propel Nikolas if he wanted to accelerate at a rate of 1.

A set of data is collected from a simple circuit with a 20 resistor and is represented in the table

A skydiver of mass m jumps from a hot air balloon and falls a distance d before reaching a terminal velocity of magnitude v. Assume that the magnitude of the acceleration due to gravity is g. a.

8. What happens to force when mass is increased?

Give an example of ionic and covalent bond, and explain and make an example for each.
