Four forces are acting on a hot-air balloon: F1 = 2280.0 N up, F2 = 2250.0 N down, F3 = 85.0 N west, and F4 = 12.0
N east. What is angle from the east or west direction of
the net external force on the balloon?

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.

Lightning is an example of what phenomenon? a release of a large amount of energy an absorption of a large amount of energy a natural electric circuit a natural electric current

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
