(a) steve exerts a steady force of magnitude 210n (about 47 lb.) on the stalled car in fig. 6.3 as he pushesit a distance of 18 m. the care also has a flat tire, so to make the car track straight steve must push at an angle of 30 degrees to the direction of motion. how much work does steve do? (b) refer to book.

In one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc

Earth has a mass of 5.97 x 1024kg, and a mean radius of 6.38 x 106m. what would be the orbital speed and period of a satellite in orbit 1.44 x 108 m above earth?
