Answer:
a) Knowns, initial speed , final speed
and gravity due it is a constant
b) The maximum high reached by the dolphin is
c) Total time is
Explanation:
a) First of all the initial speed is given at the start of the problem, gravity is constant and final speed is known any object thrown straight up reaches its max high at speed.
b) Second, now that we know final speed we use , as we clear for
.
Then we use
c)Third, finally we can use , as we know
when the dolphin fall into the water again and
, then we have
is a quadratic form
so we have
and
Answer:
The wavelength is
Explanation:
From the question we are told that
The wavelength of the red laser is
The spacing between the fringe is
The spacing between the fringe for smaller laser point is
Generally the spacing between the fringe is mathematically represented as
Here is the distance to the screen
and d is the distance of the slit separation
Now for both laser red light light and small laser point D and d are same for this experiment
So
=>
Where is the wavelength produced by the small laser pointer
So
=>
