Patrick used the model of an aerial firecracker to demonstrate two different types of eruptions on the sun. he wrote the following observations when a firecracker was lit. the firecracker shot up. an explosion was seen when the firecracker reached a certain height. which statement is correct about the eruptions on the sun represented by patrick's observations? observation 1 represents a solar wind because the solar wind creates auroras in the sky near the poles. observation 1 represents a cme because a cme is a cloud of plasma which bursts out of the sun's atmosphere. observation 2 represents a solar wind because the solar wind travels at a very high speed in a specific direction. observation 2 represents a cme because a cme is a magnetic storm on the sun which produces high energy particles.

Work = force × a. work b. energy c. distance d. momentum

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.
