Answer:
You can pick any two from these:
- Visible light: red, orange, yellow, green, blue, violet.
Explanation:
Electromagnetic energy is the is the energy that travels in form of transverse waves produced by the perpendicular oscilations electrical and magnetic fields.
An important characteristic of electromagnetic energy (waves) is that they do not need a material medium to propagate (travel) but they can travel in vacuum. That is how the sun light gets to the Earth through space.
Depending of the wavelength and frequency (which are inversely related) each electromagnetic wave has different amount of energy, involves particular risks and finds different applications.
Among other uses, we can mention: radio waves and mcirowaves are useful for communications, in infrared transmits heat, visible light permits see the objects, ultraviolet may be used in security systems, x-rays and gamma rays have medical uses.
I think that the answer might be D beacuse if he body lacks calcuim thier DIET is low on calcium
Answer:
0.61
Explanation:
Flip the sign of the value which is most negative. This means that the metal is undergoing oxidation rather than reduction because it is more reactive. In this case -0.8 becomes 0.8.
Add the two values together
-0.19+0.8
=0.61
The shape of DNA is a double helix, which is like a twisted ladder. The sides of the ladder are made of alternating sugar and phosphate molecules. The sugar is deoxyribose. The rungs of the ladder are pairs of 4 types of nitrogen bases.
Answer:
Carbon dioxide is a chemical compound composed two oxygen atoms covalently bonded to one carbon atom. Carbon dioxide's molecular shape is linear. Also carbon dioxide exists in Earth's atmosphere as a gas. Carbon Dioxide- CO2 makes up one of the gases in our atmosphere.
