Temperature is a measure of how rapidly or slowly molecules move.<span />
The matter is a collection or composition of extremely small particles called "Atoms".
<u>Explanation</u>:
- The matter is anything that has mass and which utilizes space by having volume.
- Modern scientists describe the makeup of matter as a collection of tiny substances called atoms.
- Matter can either be in solid, liquid, or gaseous state and even appear in plasma form.
- Matter can neither be created nor be destroyed but only transferred from one form to the other.
- Atoms are composed protons, neutrons and electrons. The protons and neutrons are contained in the nucleus, while the electrons orbit around the nucleus of the atom.
- Protons are positively charged, neutrons are neutral and electrons are negative.
C. Transverse Waves. I'm pretty sure Particle and Medium Waves don't exist.
<span>m1 = 5g = 0.005kg
v1 = 0
m2 = 1.0 x 10^-7g = 1.0x10^-10kg
v2 = 7.5
v3 = ?
looks like you did the formula correctly
m1v1 + m2v2 = (m1+m2)v3
0 + m2v2 = (m1+m2)v3
m2v2 / (m1+m2) = v3
(1.0x10^-10)(7.5) / (0.005 + 1.0x10^-10) = v3
1.5x10^-7 = v3
However, it said the bee gets hit by 1000 pollen grains, so I would guess you have to multiply 1.0 x 10^-10 by 1000 first, unless the total mass of the 1000 grains really is 1.0 x 10^-10.</span>
