Answer:
The path difference between the two waves should be one-half of a wavelength
Explanation:
When two beams of coherent light travel different paths, arriving at point P. If the maximum destructive interference is to occur at point P , then the condition for it is that the path difference of two beams must be odd multiple of half wavelength. Symbolically
path difference = ( 2n+1 ) λ / 2
So path difference may be λ/2 , 3λ/ 2, 5λ/ 2 etc .
Hence right option is
The path difference between the two waves should be one-half of a wavelength.
Reaction time will stay the same for each person however the faster the car is going the faster someones reaction time would need to be react to something that happened. therefore it might seem like someone had a slower reaction time when a car is moving faster because everything happens faster when you are moving faster

Answer:
<h2>39.15 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 14.5 × 2.7
We have the final answer as
<h3>39.15 N</h3>
Hope this helps you
Answer:
D) 5 W
Explanation:
Force=10N
Distance =5m
Time=10s
Power =?
But Power= Work done/Time taken
P= W/s
W= Fxd=10x5=50
P=50/10
P=5W
Answer:
|q1|/|q2| = 1/7
Explanation:
Particle 1 experiences a force F1 due to the magnetic field, B:
F1 = |q1|*v1*B
Particle 2 experiences a force F2 due to the magnetic field, B:
F2 = |q2|*v2*B
We're given that:
v1 = 7v2
Also, the force experience by both particles are equal:
F1 = F2
=> |q1|*v1*B = |q2|*v2*B
|q1|/|q2| = v2/v1
=> |q1|/|q2| = v2/7v2
=> |q1|/|q2| = 1/7
