If 10 grams of butane(C4H10), afuel in cigarrete lighter, react with 10 grams of O2, how many grams of the product will be formed
A train has a max speed of 20m/s w/c it can achieve at an acceleration of 0.25m/s². With its brake fully applied, the train has a deceleration of 0.5m/s². What’s the shortest time that the train can travel b/w stations 8k m apart if it stops at both?
An electric train develops a power of 1.0 MW when travelling at a constant speed of 50 ms-1. The net resistive force acting on the train is (Ans: 20 kN).
My work: P=FV, F=P/V, F=2x10-6

Reducing Fraction to Lowest Term
Create a Python script that will reduce an input fraction to its lowest term.
Program Requirements:
1. Define a function that will check first if the input fraction is a VALID fraction.
2. Define a function that will split a VALID fraction and return a list that consists the numerator and denominator.
3. Define a function that will accept two parameters (numerator and denominator to determine the greatest common divisor.
4. Define a function that will accept two parameters (numerator, denominator) and will return the reduced fraction.
Sample Output:
Input a fraction: 4/6
Reduced fraction is 2/3

A company makes parts for a machine. The lengths of the parts must be within certain limits or they will be rejected. A large number of parts were measured and the mean and standard deviation were calculated as 3.1 m and 0.005 m respectively. Assuming this data is normally distributed and 99.7% of the parts were accepted, what are the limits?
a 0.40-kilogram mass is sliding on a horizontal friction less air track with a speed of 6.0 meters per second when it instantaneously hits and sticks to a 2.6-kilogram mass initially at rest on the track. The 2.6-kilogram mass is connected to one end of a mass less spring, which has a spring constant of 200 newtons per meter. The other end of the spring is fixed.
