Answer:
dont have the answer but you cute
Explanation:
Okay. If a car takes 2 hours to go 80 miles, the car is going 40 miles an hour. All you have to do is 80/2 in order to get your answer, because you do distance divided by time to find the speed.
We know, m1v1 = m2v2
Here, m1, v1 = mass & velocity of cannon
m2, v2 = mass & velocity of shell
2100 * v1 = 31.5 * 500
v1 = 15750 / 2100
v1 = 7.5 m/s
In short, Your Answer would be 7.5 m/s
Hope this helps!
A general rule to help you remember the difference is that:
1) The independent variable is what you're changing in an experiment
2) The dependent variable is what you're measuring, and it's something whose measurement could change depending on whatever the independent variable is.
So in Ronald's experiment, he is changing the type of shower cleaner, making that your independent variable. He is hoping to measure the amount of soap build up that results from the change of shower cleaner, making that your dependent variable.
Independent Variable: Type of shower cleaner
Dependent Variable: Amount of soap build up
