Answer:
pressure on a given day
Explanation:
because you can't find pressure in a day
Answer:
The answer to this question is given below in the explanation section.
Explanation:
Give the relation of resistance of wire with the length and thickness:
Resistance:
There is a resistance to the flow of an electric current through most conductors.
The length of wire increases
The thickness of wire decreases
The resistance of a long wire is greater then the resistance of a short wire because electrons collide with more ions as they pass through.
The relationship between resistance and wire length is proportional. The resistance of thin wire is greater then the resistance of a thick wire because a thin wire has fewer electrons to carry the current.The relationship between resistance and the area of the cross section of wire is inversely proportional.
B Light waves travel faster than sound waves
Answer:
The correct option is (A).
Explanation:
The direction of electric force is in the direction of electric field. The electric force acting on a charged particle is given by :
F = qE, q is magnitude of charge
We have, a negative test charge experiences a force to the right as a result of an electric field. It would mean that the electric field points to the left because the force on a negative charge is opposite to the direction of the field.
Lydia is an example of an optimist. Optimists always look at the positive side of a particular situation. They believe in a positive result. Optimist always see "the bright side" as opposed to the pessimist. The word optimism comes from latin word "optimum" which means "the best".
