Why the magnetic field line doesn't cross each other? ​
riadik2000 [5.3K]

Answer:

The main reason why the magnetic field lines do not cross each other is because of the resultant force (the single force) on a north or south pole at any one point on earth can only be in one direction...

Explanation:

This means that if you were to have a compass it needle cannot be showing two different directions. THIS MEANS THAT THE MAGNETIC FORCES ACTING FROM POLE TO POLE ACTS ONLY IN ONE DIRECTION, NOT 2

A 60 w (120 v) night light is turned on for an average 12 h a day year round. part a what is the annual cost of electricity at a
Zinaida [17]

The annual cost of electricity is $28.908 .

work done is equal to energy consumed

therefore total energy is calculated as power times the duration of operation .

W=P.t

where W= work done

            P=power

            t= time of operation

therefore,

total work done (W)=0.06×12×365 kw

=262.8 kw

so total annual electricity bill = 262.8×0.11

=$28.908

sashaice [31]

Complete Question

The barometer of a mountain hiker reads 980 mbars at the beginning of a hiking trip and 790 mbars at the end. Neglecting the effect of altitude on local gravitational acceleration, determine the vertical distance climbed. Assume an average air density of 1.20kg/m^2

Answer:

h=1614m

Explanation:

From the question we are told that:

Initial Pressure P_1=980mbar=>98000Pa

Final Pressure P_2=790mbar=>79000Pa

Density \rho=1.20kg/m^2

Generally the equation for Height climbed is mathematically given by

h=\frac{P_1-P_2}{\rho*g}

h=\frac{P_1-P_2}{1.20*9.81}

h=1614m
