James E. Hansen studied climate change
Electrons flow through a wire because THERE IS A DIFFERENCE IN THE POTENTIAL ENERGY. The correct option is B.
The potential difference that exist between the electrons in an electric wire is the major reason why electrons flow through electric wires. The potential difference can be negative or positive depending on the movement of the charges. The amount of work that is needed to move a charge between two point in an electric circuit is called electric potential difference and it is measured in Volts.
Answer:
5 N
Explanation:
From the question,
The magnitude of the force that would be required to just loosen the nut when the force is applied perpendicularly at the end of the handle is
Fy = Fsinθ................. Equation 1
Where Fy = force acting perpendicular at the end of the handle, F = Force applied to the handle, θ = angle of inclination of the force to the end of the handle.
Given: F = 10 N, θ = 30°
Substitute these values into equation 1
Fy = 10(sn30°)
Fy = 10(0.5)
Fy = 5 N.
Answer:
No, he won't be drowned.
Explanation:
We have given,
The height of the student = 5 feet,
Depth of the pool( in feet ) = x ( say ) < 5 feet,
Since, the depth of the pool < height of the student,
Thus, if the student went for swimming in a pool, however he does not know swimming, he will not be drowned until he is suffering from an injury or external force.
I think force is something to do with a force being applied to a movement or is just to pull but not sure sorry if this aint right
