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.

100 ! make you brainliest! asap pleaze hurry 1. which scientific theory explains that the universe originated from a small, densely packed space? 2. observations of space show that galaxies are moving away from us as observers on earth. how is this related to how the universe formed? 3. one force is responsible for holding together stars with planets, planets with moons, and stars in galaxies. what is this force? 4. as the solar system formed, most of its mass became concentrated in one part of it. what is that that part? 5. using the law of gravitation, explain why the moon orbits the earth and the planets orbit the sun. 6. many people think that summer is warmer because the earth is closer to the sun at that time of year. your experience with seasons has taught you this is not true. explain why. 7. if earth rotated on an axis that was not tilted, how would this affect the seasons? 8. does this show the geocentric or heliocentric idea of the solar system? explain the difference. 10. as fast as you can, name the planets in order from the sun. 11. as fast as you can, name the planets in order from smallest to largest. 12. as fast as you can, name the planets in order from least mass to most mass. hint: check your notes about the gravitational force on each planet compared with earth. name a unique trait about each planet in our solar system.
