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
Answer:
O An increase in the temperature will increase the pressure.
Explanation:
Decrease in volume, more collisions, increase in temperature, more particles: all of these increase the pressure.
Answer: O An increase in the temperature will increase the pressure.
Answer:
0.025 m
0.059166 m
Explanation:
P = Pressure
A = Area
x = Compression of spring
Force is given by
From Hooke's law
The spring is compressed 0.025 m
In the second case
Net force would be
Compression would be
The compression of the spring is 0.059166 m
