An airplane releases a ball as it flies parallel to the ground at a height of 165 m. if the ball lands on the ground exactly 165 m from the release point calculate teh speed (v) of the plane. neglect andy effects due to air resistance and use g = 9.18 m/s^2 for the acceleration due to gravity.

Describe how the fermi level changes with donor level, temperature and contact with p and n type semiconductors

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?
