Where you get all the steps when you finally get a reaction . Ex, vinegar and baking soda you go step by step.
Hope this helps :)
Answer:
1341.03 V/m
Explanation:
The power output per unit area is the intensity and also the is the magnitude of the Poynting vector.
= cε₀
⇒
= cε₀
Where;
P is the power output
A is the area of the beam
c is speed of light
ε₀ is permittivity of free space 8.85 × 10⁻¹² F/m
is the average (rms) value of electric field
Making electricfield
the subject of the equation
= P / Acε₀
= √(P / Acε₀)
But area A = πr²
= √(P / πr²cε₀)
Given:
Output power, P = 15 mW = 0. 015 W
Diameter, d = 2 mm = 0.002 m
⇒ Radius,
Solving for average (rms) value of electric field;
= 1341.03 V/m
Answer:
B: precipitation seeping through pores and cracks in the ground
Explanation:
Man made wells aren't the main source because their isn't enough of them and morning dew doesn't go in to the ground in one main source.
Answer:
The electric bill for June is Rs198000
Explanation:
Convert volt to watt, but in order to do so I need to know the amps and since it is not provided I converted if the amps was 1.
I multiple 50 with 10 then with 30 so I know how much watt the fan takes at June.
Since there are 2 light bulb I multiple 10 with 2 than with 8 than with 30.
15000 watts for the fan,
4800 watts for light bulb,
add them and then times it by 10.
Rs198000
