Answers
Household lightbulbs don't emit radio, microwave, X-rays or gamma rays, and only a smidgen of ultraviolet.
The sun emits everything on the list.
The Sun emits many types of light , the ultraviolet, X-ray, and even gamma-ray, radio and infrared parts of the spectrum.
The light bulb emits very small amounts of UV light.
The Sun emits many types of light , the ultraviolet, X-ray, and even gamma-ray parts of the spectrum.But most of the Sun's light is in the infrared, visible, and ultraviolet parts of the electromagnetic spectrum.The Incandescent light bulbs, the most commonly used light bulbs in homes, give off small amounts of UV light. The UV light emitted by these bulbs is so small that it's impossible for human health to be affected in any way.Learn more:

why does the fire snake weight less than it was when it was on fire
Answers
Answer:
When Zoe weighs the ingredients (sugar and baking soda), it weighs 25 grams in total. When she weighs the “snake” it weighs 23 grams. This is because some carbon dioxide gas produced during the chemical reaction escapes into the air.
Which graph accurately shows the relationship between kinetic energy and speed as speed increases?
Answers
Answer:
B
Explanation:
kinetic energy (KE) is the energy possessed by moving bodies. It can be expressed as:
KE = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]
Where: m is the mass of the object, and v its speed.
For example, a stone of mass 2kg was thrown and moves with a speed of 3 m/s. Determine the kinetic energy of the stone.
Thus,
KE = [tex]\frac{1}{2}[/tex] x 2 x [tex]3^{2}[/tex]
= 9
KE = 9.0 Joules
Assume that the speed of the stone was 4 m/s, then its KE would be:
KE = [tex]\frac{1}{2}[/tex] x 2 x [tex]4^{2}[/tex]
= 16
KE = 16.0 Joules
Therefore, it can be observed that as speed increases, the kinetic energy increases. Thus option B is appropriate.
