Key differences between Mass and Weight
The weight may vary, but the mass is constant.
The mass is measured in kilograms (kg), while the weight is measured in newtons (N).
Mass refers to the amount of matter an object has, but the weight refers to the force of gravity acting on an object.
Answer:
Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles or photons.
Explanation:
I think its the mirror because condenser helps in allowing the amount of light to pass.
Answer:
Is an isotope of Cu (Copper)
Explanation:
Remember that the mass number will tell you the number of protons and neutrons. If you have the mass number(65) and the number of neutrons (36), you just need to subtract: 65 - 36 = 29 the number or protons.
As this is a neutral isotope, that means that is going to have the same number of protons and electrons, that is 29.
Alkynes are hydrocarbons with at least one triple covalent bond.
