Answer:
1you need too add the 3 and then multiply the answer by 3 answer 39? im not sure
Ca (NO3)2(s) ---> Ca2 + (aq) + 2NO3 -(aq)
Answer:
correct answer is 1.20 times too high
Explanation:
Let's analyze the relationship between linear and angular variables
v = w r
where w is the angular velocity of the car, which we will assume constant, r is the radius of the tire.
the normal tire has a radius ro
v₀ = w r₀
The tire with the new radius is r = 1.20 r₀\o
v = w r
v = 1.20 w r₀
v = 1.20 v₀
so the average speed is 1.20 times higher than the real speed
so the correct answer is 1.20 times too high
