Speed is the time rate at which Sue covers the distance. It is derived by dividing the total distance covered by the total time taken to cover the distance . Usually SI unit for speed is km/h or mph or m/s.
Explanation:
Speed is also referred to as velocity- so the two are synonymous.
Acceleration is the rate at which speed is increasing. It is usually given by SI unit m/s². The opposite of acceleration is deceleration which is the rate at which speed is decreasing.
Distance is the measurement, in meters of kilometers or miles or yards..etc, that has been covered from one point to another.

<span>some elements would be Beryllium, Barium, Magnesium, and Strontium</span>
The number of moles of gas in the container would be 4.62 moles
<h3>Ideal gas law</h3>
According to the ideal gas law:
PV = nRT, where P = pressure, V, volume, n = mole number, and R = constant = 8.31
In this case, V = 58.953 L, P 467.81 kPa, and T = 719.11 K
Making n the subject:
n = PV/RT = 58.953 x 467.81/8.31 x 719.11 = 4.62 moles

Answer:
4200ml
Explanation:
Converting 3.1kg to g
3.1*1000= 3100g
Since density = mass/volume, then
volume = mass/ density
Therefore volume = 3100/0.74
= 4189.2ml
converting it to two significant figures
= 4200ml
