Which of the following would describe a length that is 2.0×10^-3 of a meter? a: 2.0 kilometers
1 answer:
Answer:
Option (c)
Explanation:
Here, it is required to describe the given length in a particular unit. Firstly, we need to see the following conversions as :
1 meter = 0.001 kilometers
1 meter = 10⁻⁶ megameters
1 meter = 1000 millimeters
1 meter = 1000000 micrometers
From the given option, the correct one is (c) because, 1 meter = 1000 millimeters
So,
Hence, the correct option is (c). Hence, this is the required solution.

The free-body diagram of the forces acting on the flag is in the picture in attachment.
We have: the weight, downward, with magnitude
the force of the wind F, acting horizontally, with intensity
and the tension T of the rope. To write the conditions of equilibrium, we must decompose T on both x- and y-axis (x-axis is taken horizontally whil y-axis is taken vertically):
By dividing the second equation by the first one, we get
From which we find
which is the angle of the rope with respect to the horizontal.
By replacing this value into the first equation, we can also find the tension of the rope:
