Answer:
The answer to your question is: 15 pizzas
Explanation:
data
26 large pizzas ------ 66 students
? large pizzas -------- 38 students
Rule of three
x = 38 (26) / 66 = 14.96 ≈ 15 pizzas
Explanation:
initial velocity U = 20m/s
Final velocity V = 35m/s
time = 15.0 secs
change in velocity = 35 - 15
= 20m/s
acceleration a = change in velocity/time V/t
a = (35-20)/15
a= 15/15
Hence, your acceleration is 1m/s^2
The answer is: "nothing".
In fact, it's totally random. When there is a certain amount of atoms of a radioactive element, it's not possible to predict which atom will decay first and which one will decay later. We can only predict the amount of atoms that will be left after a certain time t (if we know the half-life of the element), but we can't predict which atom will decay first.
