As light waves enter the eye, which three structures do they pass through first?

What are Some of the Most Common Energy Sources?

A car has a mass of 12,000 kg. What is it's acceleration when the engine exerts a force of 600 N? (Formula: F=ma)

What are plants and animals that get their energy from eating other things? a. producers b. consumers c. decomposers d. herbivores

Two lightbulbs are wired in series and connected to a 12-volt battery. what happens to the current through the battery if a third bulb is wired in parallel with the other two bulbs? to the power?

What is the difference between speed and velocity

If an astronaut moved away from the earth towards the moon, how would the gravitational forces between the earth and the astronaut change? How would the gravitational forces between the moon and the astronaut change?

A race car starts from rest and speed up uniformly to the right until it reaches a maximum velocity of 60m/s in 15 sec

The magnitude of a velocity vector is called speed. suppose that a wind is blowing from the direction n45°w at a speed of 40 km/h. (this means that the direction from which the wind blows is 45° west of the northerly direction.

The y component of the electric field of an electromagnetic wave traveling in the + x direction through vacuum obeys the equation Ey = (375 N/C) cos[kx - (2.20 * 1014 rad/s) t]. What is the wavelength of this electromagnetic wave? (c = 3.
