Answer:
Electron must be placed at a distance of 2.69 ×10^5 m in the direction of positive y-axis.
Explanation:
Charge on electron = e = -1.6 × 10^-19 C
Mass of electron = m = 9.1 × 10^-31 kg
Charge at origin = q = -0.45 nC
According to given condition in the question:
Fe = Fg
kq1q2/r^2 = mg
(9 × 10^9)( -1.6 × 10^-19)( -0.45n)/r^2 = (9.1 × 10^-31)(9.8)
r = √7.2 ×10^10
r = 2.69 ×10^5 m in the positive y-axis direction
Answer:
This is very hard bit I think 6.3 my, I'm not shure.
This would be the definition of a resistor. These components inhibit or “resist” the flow of a current.
Hope this helps!
Answer:
100°C
Explanation:
The heat gained by the ice equals the heat lost by the steam, so the total heat transfer equals 0.
Heat lost by the steam as it cools to 100°C:
q = mCΔT
q = (3 kg) (2.00 kJ/kg/K) (100°C − 120°C)
q = -120 kJ
Total heat so far is negative.
Heat lost by the steam as it condenses:
q = -mL
q = -(3 kg) (2256 kJ/kg)
q = -6768 kJ
Heat absorbed by the ice as it warms to 0°C:
q = mCΔT
q = (6 kg) (2.11 kJ/kg/K) (0°C − (-40°C))
q = 506.4 kJ
Heat absorbed by the ice as it melts:
q = mL
q = (6 kg) (335 kJ/kg)
q = 2010 kJ
Heat absorbed by the water as it warms to 100°C:
q = mCΔT
q = (6 kg) (4.18 kJ/kg/K) (100°C − 0°C)
q = 2508 kJ
The total heat absorbed by the ice by heating it to 100°C is 5024.4 kJ.
If the steam is fully condensed, it loses a total of -6888 kJ.
Therefore, the steam does not fully condense. The equilibrium temperature is therefore 100°C
