Areceiver is in a jet flying alongside another jet that is emitting 2.0 x 106 hz radio waves. if the jets fly at 268 m/s, what is the change in frequency detected at the receiver?

0 Hz as there is no relative moving between jets so there is no shift in the frequency.

Explanation:

The jet in which the receiver is present and the jet which is emitting the radio waves of frequency 2.0×10⁶ Hz are moving at same speed. Hence, between the two jets, there is no relative motion and thus , for one of the system , the other is at rest. So, there will be no change in frequency as the radio waves receives the receiver with same frequency because there is no frequency shift.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
