B. Both of these types of lenses have the ability to produce real images.
Answer:
Part a)

Part b)

Part c)

Explanation:
Part a)
As we know that the diver will have zero velocity in vertical direction
so here we can say that



Part b)
as we know that


so we will have


Part c)
Distance covered by diver from the edge of the pool is given as



The relationship between the initial velocity, final velociy, distance, and deceleration can be expressed in the following equation.
2(a)(0.270 m) = 0² - (5.70 m/s)²
The value of a (which is the deceleration) is 0.06 m/s². Thus, the answer is that the deceleration value is approximately 0.06 m/s².
Answer:

Explanation:
According to Faraday-Newmann-Lenz, the induced emf in the loop is given by:
(1)
where
is the rate of variation of the magnetic flux through the loop.
We know that the magnetic flux through the loop is given by

where B is the magnetic field and A is the area of the loop. Since the magnetic field is constant, we can write the variation of flux as

So eq.(1) becomes

and the problem gives us:
is the magnetic field
is the rate at which the area changes
Substituting into the equation, we find

It moves backwards do to the impact. this is because force can not be created nor destroyed so it is transferred.<span />
