A jet aircraft is traveling at 255 m/s in horizontal flight. The engine takes in air at a rate of 116 kg/s and burns fuel at a rate of
1.69 kg/s. The exhaust gases are ejected at
651 m/s relative to the aircraft.
Find the thrust of the jet engine.

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
