Explanation:
Given that:The brief pulses of energy absorbed by the retina welds the detached portion back into place. In one such procedure, a laser beam has a wavelength of 810 nm and delivers 250 mW of power spread over a circular spot 510 μm in diameter. The vitreous humor (the transparent fluid that fills most of the eye) has an index of refraction of 1.34.A) If the laser pulses are each 1.5 ms, long, how much energy is delivered to the retina with each pulse?B) What average pressure does the pulse of the laser beam exert on the retina as it is fully absorbed by the circular spot?C) What is the wavelength of the laser light inside the vitreous humor of the eye?D) What is the frequency of the laser light inside the vitreous humor of the eye?E) What is the maximum value of the electric field in the laser beam?F) What is the maximum value of the magnetic field in the laser beam.

1. F=ma
Here we have an acceleration = 2.3 and a mass = 14
So...
F = (14)(2.3)
F = 32.2 N
2. F = ma
Here we have an acceleration = 6.4 and a force = 1473
Rearrange your equation for m
F/a = m
1473 / 6.4 = m
m = 230.16 kg
3. F = ma
Here we have a force = 94 and a mass = 45
Rearrange for acceleration
F/m = a
94 / 45 = a
a = 2.09 m/s^2
Answer: not be able to stop in time to miss the object
Explanation:
The phrase "Over-driving your headlights" means that a person is driving at such a speed that the vehicle's stopping distance is greater than the maximum viewable distance with the headlights on.
When this occurs, it will be impossible for the vehicle to stop moving in time to avoid an object viewed by the driver in the range of his headlights.
This is a <u>dangerous driving practice</u> and can be avoided by driving at <u>reduced speeds</u>.
Answer:
Because the different waves will feel like to bounce off to different directions, and different items will do different actions.
According to Newton's first law, when the net force on the body is zero, the result will be that the body will have constant velocity. So when the force of friction on fireman's hands and the weight are equal, the fireman will slide down the pole with a constant velocity.
