Answer 1

Answer:

1 = The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. ... Velocity is a physical vector quantity; both magnitude and direction are needed to define it.

2 = Nepotism is a form of favoritism which is granted to relatives in various fields, including business, politics, entertainment, sports, religion and other activities. The term originated with the assignment of nephews to important positions by Catholic popes and bishops.

3 = Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration. The concept of diffusion is widely used in many fields, including physics, chemistry, biology, sociology, economics, and finance.

Answer 2

$\huge{1.ᴡʜᴀᴛ \: \: ɪs \: \: ᴠᴇʟᴏᴄɪᴛy ?}$

Your notion of velocity is probably similar to its scientific definition. You know that a large displacement in a small amount of time means a large velocity and that velocity has units of distance divided by time, such as miles per hour or kilometers per hour.

Average velocity is defined to be the change in position divided by the time of travel.

$\\ vavg= \frac{Δt}{Δx} = \frac{tf−t0}{xf−x0}$

$\large{2. ᴡʜᴀᴛ \: \: ɪs \: \: ɴᴇᴘᴏᴛɪsᴍ? }$

Nepotism is a form of favoritism shown to acquaintances and family members. Nepotism is the act of abusing one’s power or official position to offer a job or a favor to a family member while disregarding their merit and qualification.

$\large{❸ ᴡʜᴀᴛ \: \: ɪs \: \: ᴅɪffᴜsɪᴏɴ ?}$

Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. The material that diffuses could be a solid, liquid or gas. Similarly, the medium in which diffusion occurs could also be in one of the three physical states.

One of the main characteristics of diffusion is the movement of molecules along the concentration gradient. While this could be facilitated by other molecules, it does not directly involve high-energy molecules such as adenosine triphosphate (ATP) or guanosine triphosphate (GTP).

Good morning❤!(hope it's help)
