Assuming constant acceleration, the goalie slows the ball from 18 m/s to rest in 0.035 s, so that the acceleration felt by the ball is

Answer:
The correct option is;
(b) The end A of the solenoid behaves like a north pole
Explanation:
According to Lenz's law we have that the induced emf direction in the solenoid due to the rapid introduction of the bar magnet will be such that the electric current induced will have a resultant magnet field that will oppose to the movement of the north pole of the bar magnet that resulted in the magnetic field
Therefore, the opposing magnetic pole to the north pole of a magnet is a north pole and the solenoid end A will act like the north pole.
Answer:

Explanation:
From the question we are told that:
Wavelength
m
Refraction Index 
Generally the equation for Destructive interference for Normal incidence is mathematically given by

Since Minimum Thickness occurs at
At 
Therefore



What would happen is that once the predators increase and start making the number of prey decrease, in the end there is not gonna be food because they have eaten it all. Then, the predators would start to die off due to the fault of prey for them to eat. Afterwards, the prey organisms are going to increase in number due to this and then the cycle begins again.
