<span>All electrical wires should clear eight for flat roofs and 12 for driveways. A complete electrical circuit must have a path, load, and voltage. Two wire service will only have 115V. Voltage itself is the measure of the driving force that drives the electricity in an electrical wire. Electricity in itself can be sold in quantities of kilowatt per hour. </span>
Answer:
B
Explanation:
B makes the most sense in my opinion. because different discoveries have influenced many factors of the world
Answer:
1.) Wavelength
2.) Number of fringes
Explanation:
1.) If we split a laser beam by using a diffraction grating slide, then we can
verify the wavelength by applying the formula λ = ds/l.
2) If we split light into its individual wavelengths using a diffraction grating,
then we can determine the number of fringes by multiplying the spacing of the gradient lines (d) times the distance to the central maxima of the color band (s) divided by the length distance from the grating slide to the screen (l).
The water is already at its boiling point
, therefore we don't need additional heat to increase its temperature. Instead, we have to give the heat necessary to make it evaporate. The energy needed is equal to
where
m is the mass of the water
Lv is the latent heat of evaporation
The latent heat of evaporation of water is
, and the mass of this sample of water is
, therefore the heat needed to vaporize the water is
