Mass and velocity I think
The car, because logically, a car is faster and if you do the math, 300 meters per minutes is about 17 kilometers per hour, and that is lower than the car’s 36 kilometers per hour. I would show you my work but im tired man, please mark me brainliest
Answer:
Gravitational, Electrical, Magnetic, elastic potential, and chemical energy
Explanation:
When I did some research, I found 5 types of potential energy, so list the four that either came up in your lesson or are familiar to you:
Gravitational, Electrical, Magnetic, elastic potential, and/or chemical energy.
Answer:
Ex1.
a) Carbon : atomic number Z = 6 and mass number A = 12
b) Protons = 6; electrons = 6 ; neutrons = 6.
Ex2.
Molar mass of H₂O₂ = 34 g; BaF = 156 g; CO = 28 g.
Explanation:
Ex1.
a) the element with atomic number 6 and mass number 12 is carbon
b) number of protons and electrons in a element is given by its atomic number; and for neutrons its mass number - atomic number (A-Z).
⇒ protons = Z = 6; electrons = Z = 6.; neutrons = A-Z = 12-6 = 6.
Ex2.
Molecular formula of hydrogen peroxide is given by H₂O₂.
⇒ molar mass = 2×mass of hydrogen + 2×mass of oxygen
⇒ molar mass = 2×1 + 2×16 = 34.g
molar mass of BaF = mass of barium + mass of fluoride.
= 137 + 19 = 156 g
molar mass of CO = mass of carbon + mass of oxygen
= 12 + 16 = 28 g
