Compare the collision between two baseballs and a catcher's mitt. Case A: A baseball pitched at 40 m/s collides with a catcher's mitt and is brought

to a stop. The catcher holds the mitt rather rigidly and retracts backwards very little

as the ball strikes the mitt

Case B: An identical baseball pitched at 40 m/s collides with a catcher's mitt and

is brought to a stop. The catcher holds the mitt with a relaxed arm and retracts

backwards 30 cm as the ball strikes the mitt.

What is the temperature in degrees celsius of a substance with a tempature of 49k

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
