Answer:
B
Explanation:
Given:-
- The charge of the test particle q = 3.0 * 10^-9 C
- The force exerted by the metal sphere F = 6.0 * 10^-5 N
Find:-
The magnitude and direction of the electric field
strength at this location?
Solution:-
- The relationship between the electrostatic force F exerted by the metal sphere on the test-charge and the Electric Field strength E at the position of test charge is given by:
F = E*q
- Using the data given we can determine E:
E = F / q
E = (6.0 * 10^-5) / (3.0 * 10^-9)
E = 20,000 N/C
- The direction of electric field is given by the net charge of the source ( metal sphere). The metal sphere is negative charge hence the direction of Electric Field strength E is directed towards the metal sphere.
c. Wind power can turn turbines to generate electrical power.
Explanation:
The correct statement of all is that wind power can turn turbines to generate electrical power.
This is simply the way wind energy from waves are usually harnessed to produce electricity.
- When a metallic conductor passes in between magnetic fields, it induces and generates electricity as it turns.
- This is how electricity generating plants are fashioned.
- Geothermal energy is not generated from moving water. It is produced from heat within the earth brought to the surface. Power from moving water is hydroelectric power.
- Oil is a non-renewable resource
- Propane is a non-renewable resource

I need help on this to I have to get the answer fast
Answer:
Just as images are reflected from the surface of a mirror, light reflected from a smooth water surface also produced a clear image. ... Consequently, the outgoing rays are reflected at many different angles and the image is disrupted. Reflection from such a rough surface is called diffuse reflection and appears matte.
