Given parameters:
Speed of car = 50m/s
Time of travel = 5minutes (300s)
Unknown;
Distance of travel = ?
To solve this problem, we need to understand how speed relates with distance and time.
Speed is a physical quantity. It is the distance traveled divided by time taken.
Speed =
So,
Distance = speed x time
Input the parameters and solve for the distance;
Distance = 50m/s x 300s
Distance = 15000m
The distance covered during this time interval and speed is 15000m
Answer:
So the repulsive force between the pith ball will be
Explanation:
We have given that the pith ball have the equal charge q = -40 nC =
Distance between the charges = 10 cm =0.1 m
According to coulombs law
So the repulsive force between the pith ball will be
Answer:
223.55 W
Explanation:
v = Velocity of wind = 10 m/s
r = Radius of circle = 5 m
S = Swept area
= Density of air = 1.2 kg/m³
= Power coefficient = 0.593
The maximum possible power that can be produced by the turbine is 223.55 W
