A fighter aircraft lands with an initial velocity V0 and moves with a constant acceleration of a= -8m/s^2 for a time interval t=10s. If the velocity after 10 seconds of landing is v=10m/s then calculate the initial velocity.

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

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? ( be thorough on your answer)
