Answer:
Explanation:
<u>The Electric Potential</u>
The electric potential at a point is equal to the electric potential energy (measured in joules) of any charged particle at that location divided by the charge (measured in coulombs) of the particle.
To calculate the electric potential of a point charge Q at a distance r, we use the formula:
Where
We are given the following data:
r = 4.20 m
Calculating:
Answer:
C
Explanation:
From the question we are told that a vector on the x and y plane face their negative axis
Generally in the x and y plane thr negative y axis is made to face down opposite the positive y axis
Whilst the negative x axis faces the left which is also alternate to the positive x axis
Generally A vector pointing towards the x and y negative axis fro the origin (0) will definitely be in the third quadrant
Answer:
Explanation:
The magnetic field B inside long solenoid with current I is given as
where
N is number of turn of solenoids = 1140 turns
I is current that passes through solenoid
L is length along which current pass = 0.350 m
plugging value to get required value of current
Answer:
€0.98 per liter = 4.377 doller per gallon
Explanation:
It is given that, In Europe, gas cost approximately €0.98 per liter. We need to convert it into dollars($) per gallon.
We know that, 1 euro = 1.18 United States Dollar
1 litre = 0.264172 US gallon
Cost of gas in Europe is €0.98 per liter.
