Quinn launches two projectiles, x and y, at two different speeds. which best compares the motion of the projectiles? the horizontal velocity of projectile x is changing, and the vertical velocity of projectile y is constant. the vertical velocity of projectile y is changing, and the horizontal velocity of projectile x is constant. the horizontal acceleration of projectile x is –9.8 m/s2, and the vertical acceleration of projectile y is 0 m/s2. the horizontal acceleration of projectile y is –9.8 m/s2, and the vertical acceleration of projectile y is 0 m/s2.

Automobile fuel efficiency is often measured in miles that the car can be driven per gallon of fuel (mpg). heavier cars tend to have lower fuel efficiencies (lower mpg ratings). which variable (weight or fuel efficiency) is most naturally considered the explanatory (predictor) variable in this context?

What does si stand for,when referring to a system of measurement

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.
