The net force is 300N since 600N - 300N = 300N. This is true because the forces are opposing each other. So the final answer would be 300N to the RIGHT.
Answer:
1.74 × 10^-3 m ( 1.74 mm)
Explanation:
Using Torricelli"s equation to calculate the speed of water at the surface of the hole and assuming that the speed of water at the surface of the tank is zero
v ( speed of water at the surface of the hole) = √ 2g(h1 - h2) where h1 - h2 is the difference in height which 16 m
v = √ 2×9.81×16 = 17.72 m/s
work done in ( m³/s) = 2.5 × 10^ -3 / 60 seconds = 4.2 × 10^-5 m³/s
work done = A × v
4.2 × 10^-5 = A × 17.72
4.2 × 10^-5 / 17.72 = A
2.37 × 10^-6 = A where A is assumed a circle ( πr²)
r = 2.37 × 10^-6 / π = √2.37 × 10^-6 / 3.142 = 0.869 × 10 ^ -3
diameter = 2r = 2 × 0.869 × 10^-7 = 1.74 × 10^-3 m
Answer:
C . All of the different types of electromagnetic waves
net force= the sum of all the forces acting on the object
the frictional force is opposite to the direction of motion of the object
If the object moves to the right (positive) then the friction force moves to the left (negative).
so the net force: 50 N - 5 N = 45 N (B)
