Answer:
To make the lifting more efficient. It lets there be less taxing and saves a ton of energy!!
Explanation:
Answer: well if it isnt moving, then there would not be any potentiol energy. Sothe answer is 0. I hope this helps :) Thank you. Plz mark brainliest.
Explanation:
Have in mind: Energy is always conserved and, (...) be transferred between objects or systems, from one form to another.
Hence, the true relation is C, when a system gains kinetic energy, it loses potential energy.
Think about this,
K + P = constant
If K increases, then P need to decreases to holds the above relation.
Answer:
424.26 m/s
Explanation:
Given that Two air craft P and Q are flying at the same speed 300m/s. The direction along which P is flying is at right angles to the direction along which Q is flying. Find the magnitude of velocity of the air craft P relative to air craft Q
The relative speed will be calculated by using pythagorean theorem
Relative speed = sqrt(300^2 + 300^2)
Relative speed = sqrt( 180000 )
Relative speed = 424.26 m/s
Therefore, the magnitude of velocity of the air craft P relative to air craft Q is 424.26 m/s
