In a TV set, an electron beam moves with horizontal velocity of 2.5 × 10^7 m/s across the cathode ray tube and strikes the screen, 40 cm away. The acceleration of gravity is 9.8 m/s^2 .

How far does the electron beam fall while traversing this distance?

Answer in units of m.

However, had it been a real sound, the sound's pitch would have been increased by the doppler effect, since the falcon was moving the source of the sound. perpendicular to away from towards at the same speed as

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples?
