A proton is moving in the positive x-direction as shown in Figure 2 with a speed of 1.25 × 106 m s

−1

. Then, the proton enters the region between the two plates.

The potential difference between the plates is 200 V. The electric potential of the upper

plate is higher than the electric potential of the lower plate. The separation distance

between the plates is 35.0 mm. Determine the direction and the magnitude of the

magnetic field that is required between the plates for the proton to continue traveling

in a straight line in the positive x-direction.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

wavelength divides in half and speed stays the same.

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
