Answer:
difference in flight time= 0.3023 hour
Explanation:
The question is incomplete, but I found it in your textbook.
Spped of aircraft = 850 km/h
Opposing speed of wind = 90km/h
Hence, the net speed when it's travelling west = 850 - 90 = 760 km/hr
The distance covered = 1200km
time taken = distance/ time = 1200/ 760 = 1.5789 hours
When coming back, the speed of the wind is complementary to the speed of the aircraft so
net speed when it's coming back = 850 +90 = 940 km/hr
time taken in this instance = 1200/ 940 = 1.2765 hours
Hence, the difference in flight time= 1.5789 - 1.2765 = 0.3023 hour
The choices can be found elsewhere and as follows:
A)There will not be a change.
<span>B)The voltage will decrease by a factor of two. </span>
<span>C)The voltage will increase by a factor of two. </span>
<span>D)The two coils of wire will cancel out the magnetic field. </span>
<span>E)The voltage will be zero.
</span>
I believe the answer is option C. If the magnet is put inside two coils of wire, then the voltage will increase by a factor of two. Hope this answers the question.
Go neutreal, turn blinkers on, then brake onto the side of the road.
Answer:
Because the bullet is smaller and has a sharp/pointy tip.
Explanation:
The bullet kinda puts the majority of kinetic energy in a small are, whereas the gun butt kinda spreads the energy evenly amongst a larger surface. If more explanation is needed add comment.
Answer:
Explanation:
Mechanical waves and electromagnetic waves are the types of waves we have. The major difference between this type of waves is that, while mechanical waves requires material medium for its propagation, electromagnetic waves does not require material medium for its propagation.
Example of mechanical waves are waves produced by a ripple tank.
Example of an electromagnetic waves are the electromagnetic spectrum which includes radio waves, infrared waves, visible light, ultraviolet rays etc... This waves are produced naturally without any medium compare to mechanical wave.
