What happens when a negatively charged object A is brought near a neutral object B? A. Object B gets a negative charge.
B. Object B gets a positive charge.
OC. Object B stays neutral but becomes polarized.
OD. Object A gets a positive charge.
OE. Object A loses all its charge.

Current 1 of 8.4 a runs for 240 seconds and then stops. current 2 is 10.5 a. how long does current 2 have to un to deliver the same amount of charge as current 1? 88.28 192 s 2016 s 21,000 s

What is the final velocity of the initial velocity of 25 and -50?

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.
