Answer:
x = 400 [m]
Explanation:
To solve this problem we must use the following kinematics equations, first, we find the final speed, and then we proceed to find the distance traveled.
where:
Vf = final velocity [m/s]
Vi = initial velocity = 15 [m/s]
a = acceleration = 5 [m/s^2]
t = time = 10 [s]
Note: the positive sign in the Equation indicates that the car is accelerating, i.e. its speed is increasing.
<u>Now replacing</u>
Vf = 15 + (5*10)
Vf = 65 [m/s]
Now using the second equation:
where:
x = distance traveled [m]
x = (65^2 - 15^2)/ (2*5)
x = 400 [m]
In the same direction as the force
Answer:
Explanation:
the variations in riser height or tread depth should not be grater than that is equal to 9.5 mm but the maximum riser height should be the 
but variation in riser height should not exceed to . The minimum riser height should be 7 inches which is equal to the 178 mm
Adhesive.
Adhesive is the force of attraction between molecules of different kind. Liquid flows upward the wick because the adhesive force between the wick and the liquid is higher than cohesive forces in the liquid.
When the adhesive force between the wick and the liquid is high we have capillarity taking place. This cause the liquid to move up the wick.
