Explanation:
A catalyst i think is the answer
Answer:
relationship between four fundamental physical properties of gases: pressure PP, volume VV, number of moles nn, and the absolute temperature TT. The ideal gas constant is denoted by RR and its exact value depends on the units chosen for the other parameters. Note that the temperature is always in Kelvins (i.e., we use the absolute temperature). The relation is:
PV=nRT
Answer:
a = -2.4 ms⁻²
Explanation:
Given data:
Initial velocity of car = 37.1 m/s
Final velocity of car = 29.8 m/s
Time taken to change velocity = 3 sec
Acceleration of car = ?
Solution:
Formula:
a = Vf - V₀ / t
Vf = Final velocity
V₀ = Initial velocity
a = acceleration
t = time taken to change velocity
Now we will put the values in formula.
a = 29.8 m/s - 37.1 m/s / 3 s
a = -7.3 m/s/ 3s
a = -2.4 ms⁻²
Negative sign show that car is slowing down.
