Answer:
v2 = 12m/s
Explanation:
To find the velocity of water in the lower tube you use the following formula:
(1)
v1: velocity in the first tube
v2: velocity in the second tube
A1: area of the first tube
A2: area of the second tube
From the expression (1) you can obtain the velocity v2, that is the velocity of water in the second tube:
you replace the values of the parameter in order to calculate v2:
hence, the velocity of the water is 12m/s
Answer: Noah's speed is 20km/hr
Explanation:
Given;
Final Distance between them at 5pm =320km
Time of travel = 5pm - 1pm = 4 hours
Let x represent Noah's speed
The Ryan's speed = 3x
Total distance between them in 4hours given that they are traveling at opposite directions is.
Distance = speed × time
(x + 3x) × 4hours = 320km
4x × 4 hours = 320km
x = 320km/(4×4hours)
x = 20km/hr
Noah's speed is 20km/hr
That is wan an exothermic reaction. and that the reactants formed 1 or more different products
