Answer:
C. is always perpendicular to the surface of the conductor
Explanation:
On a charged conductor , electric charge is uniformly distributed on its surface . The lines of forces are also uniformly distributed on all directions . They repel each other so they emerge perpendicular to the surface so that they do nor cut each other and at the same time they remain at maximum distance from each other.
Light Independent Reactions
It depends on where the sun and earth is.
Option (B)is correct.
Alternating electric and magnetic fields has electromagnetic radiation that travel in the form of a wave.
The varying or alternating electric field produces the varying magnetic field.This varying magnetic field in turn produces varying electric field . Thus these varying electric and magnetic fields travel in the form of electromagnetic waves. These electromagnetic waves travel with the velocity of light.These are transverse in nature.
Answer: The perpendicular force to be used to tighten the bolt is
F=347.8N
Explanation:
Mathematically the torque is expressed as
T=F*L
Where T= torque in Nm
F= force in N
And L = perpendicular distance
Now given
T=63.3Nm
L=18.2cm to meter 18.2/100
0.182m
F=?
Making F the subject of the formula in our equation
F=T/L
F=63.3/0.182
F=347.8N
What is torque?
Torque is the product of force and perpendicular distance of the line of action.
