A fighter jet takes-off from an aircraft carrier and climbs in the air with an angle of 42.1 degrees above the horizontal and a speed of 122 m/s.The speed and direction of the jet constitutes a vector quantity known as the velocity.What is the horizontal component of the plane's velocity?
An air bubble of volume 0.5cm3 when released at the bottom of a lake rise's to the surface of the lake.Explain why
Explain what infrared radiation is and answer the following questions: How is infrared radiation different from visible light? Why does the JWST observe infrared light, and what are the scientificadvantages for astronomers?
Why is the orbit of the telescope stable nonetheless? What otherforces need to be considered?
The centrifugalFω and gravitational forceFG are acting on objects orbiting the Sun: F = Fω−FG
(c) Based on this, how much should the telescope accelerate towards or away from the Sun?
Helium (He) gas initially at 2 bar, 200 K undergoes a polytropic process, with n = k, to a final
pressure of 14 bar. Determine the work and heat transfer for the process, each in kJ per kg of
helium. Assume ideal gas behavior.
