Answer:
for this i uploaded i screenshot
Explanation:
5.7 km/h north and 5.8 km/h west are instantaneous velocities, while 8.1 km/h northwest is the average velocity.<span>
The answer choice above is correct.
The instantaneous velocities are the actual </span>velocities while traveling ( the velocity during that instant ). The average velocity is the average of the instantaneous velocities ( the speed in one direction equivalent to the two speeds <span>in different directions ).
I used speed in the explanation because velocity is speed with direction.</span>

What is the smallest unit of a substance that keeps all of the physical and chemical properties of that substance?
Molecules is the smallest unit of a substance that keeps all of the physical and chemical properties of that substance. It is a group of atoms bounded together, and it can participate in a chemical reaction/

Argon come from the air. It is a noble gas present in atmosphere. The percentage of argon in air is about 0.93%. Naturally, it is a colorless and odorless gas. When electrifies it gives a blue-green glow. Argon laser is used in field of medicine and surgery.
Answer:
ω = B₀q/m
Explanation:
The centripetal force on the charge equal the magnetic force on the charge. (Since the trajectory is a circle). So, mrω² = B₀qv.
v = rω The speed of the charge and r = radius of path
mrω² = B₀qrω
ω = B₀q/m
The angular frequency ω = B₀q/m
