Based on the information you provided, this means the wave is traveling 50 meters every ten seconds. Meaning it is traveling 50/10 meters per second.
When you simplify you get 5 meters per second.
Answer:
What part of the light wave is related to the brightness of the light?
Amplitude
The amplitude of a wave tells us about the intensity or brightness of the light relative to other light waves of the same wavelength
The brightness of light is related to intensity or the amount of light an object emits or reflects. Brightness depends on light wave amplitude, the height of light waves. Brightness is also somewhat influenced by wavelength.
Regardless of where the cars are in the loop, centripetal force is always directed toward the center of rotation. So even if a car you're riding in is at the top of a loop, upside-down, you will feel pressed into your seat.
Energy transfer is when a energy transfers from a body/object to another.
Energy transformation is when energy is transformed into another form.
There is an energy transfer from the heat lamp to the baby zebra.
Chemical equations can be written down in 3 steps:
As example I’ll using the rusting of iron (as given)
1) Write down the products that react on the left side of the arrow.
2) Write the products after the reaction on the right side of the arrow. If there are one or more of a different atom that isn’t on the other side of the equation, the reaction is missing something on either sides.
Fe -> Fe2O3
But as you can see there are no O on the left side. The right formula is:
Fe + O2 -> Fe2O3
Review to make sure you wrote down everything.
3) Count all the atoms of each elements on each side. Balance out the amount of atoms on both sides by adding coefficients to your compounds
Take note that you need to multiply all the elements in the compound times the number
Fe + O2 -> Fe2O3
We need at least 2 iron atoms to balance out on the iron.
2Fe + O2 -> Fe2O3
Now we see that we have 2 O atoms on the left and 3 on the right. The smallest number that is divisable by both 2 and 3 is 6. Add coefficients in front of O2 and Fe2O3.
2Fe + 3O2 -> 2Fe2O3
Now we see that on the right there are 4 iron atoms. Balance out by multiplying iron on the left by 2.
4Fe + 3O2 -> 2Fe2O3
This is the final equation.
