In a specific city, electricity costs $ 0.13 per kW ⋅ h . What is the annual cost for electricity to strength a lamppost for 8.00 h

centregalilee.com:

37.96usd , 9.49usd

Explanation:

From the data given we have

cost the electricity= $0.13,

and yearly cost of power is express as

Annual cost= strength *hours*days*cost of electricity

note the unit that power have to be in kilowatt(Kw),

a. To recognize the price of running 100w we very first convert come kw

*

Hence the yearly cost of running it 8.00 hrs per day is calculated together

*

b. To identify the expense of to run 25w we very first convert to kw

*

Hence the annual cost of to run it 8.00 hrs per day is calculated as

*

Hence from the centregalilee.coms we can conclude that less amount of money compelled to run the 25w incandescent pear compare to the 100w

A spherical capacitor includes a charge of 3.50 nC when linked to a potential distinction of 230.0 V. That is plates room separated
Flura <38>

centregalilee.com:

(A). The capacitance is

*

(B). The radius that the inner sphere is 0.0327 m .

(C). The electric field just external the surface of the inner round is

*

Explanation:

Given that,

Charge = 3.50 nC

Potential difference = 230.0 V

Radius = 4.30 cm

(a). We should calculate the capacitance

Using formula the capacitance

*

*

*

(b). We have to calculate the radius of the within sphere

Using formula of capacitance

*

Put the value right into the formula

*

*

*

*

*

*

*

(c). We should calculate the electric field just exterior the surface of the inside sphere

Using formula of electrical filed

*

Put the value right into the formula

*

*

Hence, (A). The capacitance is

*

(B). The radius that the inner round is 0.0327 m .
