Answer: C
X = Displacement of the spring
Hooke's law: It states that the applied force F is proportional to the displacement of spring .
F ∝ x
Where, x = displacement of spring in meters
F = force, measured in Newtons
In another words The force F is equal to the constant K times the disparagement.
F = k.x
Where k is constant and it depends on elastic material.
Spring has restorative force.
If the spring moves in opposite direction then,
F = - k.x
A negative sign indicates that the spring resists and force is to the left. The compression of the spring is greater than the restoring force.
Example: A mass 'm' stretches a spring at a displacement x.
The answer is:
71.6 <span>°F</span>
In which it is the plane in which charges move. for example in electromagnetic waves polarization<span> means the plane in which electrons oscillate. ... it is the distribution of electric charges (electron) in an object. </span>induction<span> of charges takes place in some insulators just by some mechanical interaction such as rubbing</span>
Answer: Less than 4 ohms
Explanation:
We have three resistors with the following resistance:
Now, when the resistors are connected in parallel, the total resistance 
is calculated as follows:
Isolating :
Rewriting with th known values:
Finally:
Hence, the correct option is less than 4 ohms.
