Answer:
A) 72° or 71.56°
Explanation:
We have two components on the X-axis and y-axis respectively. So we can use the tangent of the angle to be able to find the angle with respect to the horizontal component.
Ax = 2.5
Ay = 7.5
tan(α) = 7.5/2.5
α = 71.56°
QUESTION: A pure jet engine propels and aircraft at 340 m/s through air at 45 kPa and -13C. The inlet diameter of this engine is 1.6 m, the compressor pressure ratio is 13, and the temperature at the turbine inlet is 557C. Determine the velocity at the exit of this engines nozzle and the thrust produced.
ANSWER: Due to the propulsion from the inlet diameter of this engine bring 1.6 m allows the compressor rations to radiate allowing thrust propultion above all velocitic rebisomes.
Answer:
(a)
(b) h is the same
Explanation:
According to the law of conservation of energy:
The skier starts from rest, so 
and we choose the zero point of potential energy in the end of the ramp, so 
. We calculate the final speed, that is, the speed when the skier leaves the ramp:
Finally, we calculate the maximum height h above the end of the ramp:
The initial vertical speed is given by:
and the final speed is zero, solving for h:
(b) We can observe that the height reached does not depend on the mass of the skier
Answer:
empty space
Explanation:
Our solar system comprises of the sun as the star, the planets, the dwarf planets, various moons, and plenty of asteroids, comets, and meteoroids. However, the majority part of the solar system consists of a void or empty space. These empty spaces basically composed of planetary dust and gas.
Hence, it can be concluded that Most of our Solar system is composed of "Empty Spaces."
