Why does the modern atomic theory today represent the best explanation scientists have to offer?
Modern technology supports the current atomic theory.
The math answer is:. The cheetah 'gains' (100-80)=20 km on the gazelle, so it takes (70/20)=3.5 hours to close the gap and catch its prey. ///// The real-world answer is:. Neither animal can keep up that speed for more than a few minutes. Either the gazelle totally runs out of gas and gets caught in a short time, or else the cheetah poops out and goes off to find some nearer prey.
<h3><u>Answer</u> :</h3>
◈ Average speed is measured as the ratio of total distance travelled to the total time taken.
<u>Given</u> : d = 10km and t = 40min
<u>To Find</u> : Vav

፨ <u>Conversion</u> :-
60 min = 1 h
40 min = 40/60 = 2/3 h
Answer:
simple, Volt =change in potential energy/Charge
the unit of energy is newton meter (Force*distance)
the unit of charge is coloumb
So, Volt/meter=newton* meter/coloumb*meter
=newton/coloumb (hence proved)
This unit is the potential drop per unit of length in a conductive wire with uniform resistance
