Answer:
572.85 v
Explanation:
V = IR
V = 100.5 * 5.7 = 572.85 v
The length of the wire used is 3.162 m
<h3>Resistivity of a material</h3>
The formula for calculating the power is expressed as;
P = V²/R
Determine th resistance
R = V²/P
Determine the resistance of the heating coil by substituting
R = (110²/500)
R = 12100/500
R = 24.2ohms
Determine the length of the wire
R = ρL/A such that;
L = RA/ρ
Substitute the given parameters
diameter = 0.5 mm = 0.0005m
radius = 0.0005/2 = 0.00025 m
Determine the area
A = πr²
A = π * 0.00025²
A = 1.96*10^-7 m²
Determine the length
L = (24.2 * 1.96*10^-7 / 1.50*10^-6) =
L = 3.162 m
Hence the length of the wire used is 3.162 m
The length of the wire used is 3.162 m

#SPJ4
It is force because work/distance= force
Answer:
0.0473m
Explanation:
345 ml = 0.000354 m3
6.5 cm = 0.065 m
20g = 0.02 kg
Since can is half filled with water, the water volume is 0.000354 / 2 = 0.000177 m cubed
Let water density be 1000kg/m3, the mass of this half-filled water is
1000*0.000177 = 0.177 kg
The total water-can system mass is 0.177 + 0.02 = 0.197 kg
For the system to stay balanced, this mass would be equal to the mass of the water displaced by the can submerged
The volume of water displaced, or submerged can is
0.197 / 1000 = 0.000197 m cubed
Then the volume of the can that is not submerged, aka above water level is
0.000354 - 0.000197 = 0.000157 m cubed
The base area of the can is
The length of the can that is above water is
0.000157 / 0.003318 = 0.0473 m
<span>The one that does not separate white light into the colors of the visible spectrum is A, rods in the retina of the human eye. The rod is a cells that can work in less extreme light than the other sort of visual photoreceptor, cone cells. Poles are generally discovered accumulated at the external edges of the retina and are utilized as a part of the fringe vision.</span>
