Answer:
755.7 seconds
Explanation:
Distance between Sun and Mars = 226.71 * 10^9 m
Speed of light = 3 * 10^8 m/s
Speed = distance/time
Time = distance/speed
Time = (226.71 * 10^9)/(3 * 10^8)
Time = 755.7 s
Answer:
the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. In electric circuits this charge is often carried by electrons moving through a wire. Aug 29 2019
Explanation:
Answer:
(a) R = 224.37 Ω
(b) ρ = 7.18 x 10⁻⁷ Ω.m
Explanation:
(a)
From Ohm's Law we have the following formula:
V = IR
where,
V = Voltage = 116 volts
I = Current Passing through bulb = 0.517 A
R = Resistance of light bulb = ?
Therefore,
116 volts = (0.517 A)R
R = 116 volts/0.517 A
<u>R = 224.37 Ω</u>
<u></u>
(b)
Now, the formula of resistance of a wire is:
R = ρL/A
where,
ρ = resistivity of bulb = ?
R = Resistance = 224.37 Ω
L = Length of Wire = 0.533 m
A = Cross Sectional Area of Wire = πr² = π(2.33 x 10⁻⁵ m)² = 1.7 x 10⁻⁹ m²
Therefore,
224.37 Ω = ρ(0.533 m)/(1.7 x 10⁻⁹ m²)
ρ = (224.37 Ω)(1.7 x 10⁻⁹ m²)/(0.533 m)
<u>ρ = 7.18 x 10⁻⁷ Ω.m</u>
Answer:
D) Report the problem to your supervisor.
Explanation:
This is probably the most efficient way get them to stop or to get them to follow the rules <3
