A car of mass 850 kg rests on a slope at 25 to the horizontal. Calculate the magnitude of the component of the cars weight which acts parallel to the slope

Sort the images based on whether there's a force of attraction or repulsion between the magnets shown. attraction repulsion

Aphase diagram assumes is kept constant.

Abeam of electrons moves at right angles to a magnetic field of 4.5 × 10-2 tesla. if the electrons have a velocity of 6.5 × 106 meters/second, what is the force acting on the electrons? the value of q = -1.6 × 10-19 coulombs.
