PLEASE HELP AP PHYSICS QUESTION ON PENDULUMS Manipulate the collected data so that when graphed the slope of a linear regression line yields “g.” Use the two blank columns to display your data for your manipulated axes. Please show all work for your manipulated data in the space below. Once you’ve filled in your data, plot the manipulated data on the attached graph paper, calculate the slope as well as the r^2 value of the line. Make sure to label all the appropriate areas on your graph.
(Note: while the graph paper I’ve attached appears to have the origin in the middle, make sure to put your origin in the lower left corner as always.)

How can you increase the strength of an electromagnet?

Explain what happens at the saturation point when adding salt to water at room temperature.

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
