1. calculate agni's average speed during the race.
1 answer:
The formula to find the speed/velocity is :
v = Δx/Δt = (
B.
1. From the graph given, we can get an information such as the distance travelled, and the time given.
2. If the graph are horizontal, it means that the Agni's speed is zero because Agni doesn't move.
3. If the question ask the velocity during all time, we can say that the velocity is :
.
4. So, the final velocity can be found by looking the third part of the graph. So,..
Hope this will help you :)

Answer:
Because the object should shrink its volume to zero, which is impossible
Explanation:
Let's talk about gases for simplicity. Ideal gases are governed by the ideal gas equation:
where
p is the gas pressure
V is the volume of the gas
n is the number of moles
R is the gas constant
T is the absolute temperature
From the formula, we see that T and V are directly proportional: therefore, in order for a gas to have an absolute temperature of zero, it must also have a volume of zero, which is impossible.
