Explanation:
the enerfy of of one photon of this light is 4.85x10^-19 J
<h2>E= 6.63 x 10^-34 J/S x 7.32 x10^14 S ^-1</h2>
E= 4.85x10^-19 J
Answer:
love triangle?- orr they can figure something out
Answer:
0.0922 J/g°C
Explanation:
Use the formula Q=mc(delta)T. My teacher called it "M"cat to help my class remember it. Q-energy(560J) M-mass(130.6g) c(specific heat) is what you are solving for and delta T is the change in temperature(66.5-20.0). Put these values in the formula and solve for c.
The answer is labels on lead-based paint
Lead is highly toxic metal and it is very strong poison. Lead poising takes place when lead builds up in the body. A little amount of lead can also cause various health problems.
Labels on lead-based paint do not prevent lead poisoning as much as advised to not using such product.
Instead of using lead-based paint, people could use safer products such as titanium-white based paint, which is proved to be less toxic.
Thus, option (A) is correct answer i.e. labels on lead-based paint is not among the current strategies which is used to prevent lead poisoning.
Electromagnetic waves
Unlike mechanical waves, these waves can travel though vacuum because they do not need a medium of travel.
Explanation:
This is how sunlight reaches earth. Sunlight has many wavelengths if electromagnetic waves called an electromagnetic spectrum. The electromagnetic spectrum ranges from the high energy waves called gamma rays (they have the shortest wavelength and highest frequency). On the other end of the spectrum are the lowest energy waves called radio waves (they have the longest wavelength and lowest frequency).
