    Mass
In summary, collective mass refers to the combined mass of a group of objects or individuals, calculated by adding together the individual masses of each object or individual in the group. It is important because it helps us understand the total amount of matter in a group and how it affects the environment and other objects. It can change if objects or individuals are added or removed from the group, or if there are changes in individual masses. It is different from individual mass, which focuses on the mass of a single object or individual.

On a dry day, your body can accumulate static charge from walking across a carpet or from brushing your hair.
If your body develops a charge of -10 (microcoulombs), how many excess electrons has it acquired?

N=6.2*10^13 electrons



What is their collective mass?
Express your answer using two significant figures.

FAQ: Mass of an electron: 9.11 x 10^-31 kg

What is their collective mass?

Their collective mass refers to the combined mass of a group of objects or individuals. It is the total amount of matter that makes up the group.

How is collective mass calculated?

Collective mass is calculated by adding together the individual masses of each object or individual in the group. This can be done by using a scale or by measuring the mass of each object and then adding them together.

Why is collective mass important?

Collective mass is important because it helps us understand the total amount of matter in a group and how it affects the environment and other objects. It can also be used to determine the strength of gravitational pull within the group.

Can collective mass change?

Yes, collective mass can change if objects or individuals are added or removed from the group. It can also change if there are changes in the individual masses, such as through weight loss or gain.

How is collective mass different from individual mass?

Collective mass is the combined mass of a group, while individual mass refers to the mass of a single object or individual. Collective mass takes into account the total amount of matter in the group, while individual mass focuses on one specific object or individual.
