Answer:
The electric current through the resistor is: 7.66667 milliamps
Explanation:
Applying Ohm's law we have or solving to so now, we can replace the values given before in the equation, we need to know that the voltage across the resistor is which determine the current in the component, in this case, the resistor. After clear this topic, we get so 1 milliamps is 0,001 amps we get 7,66667 milliamps.
Answer:
What is Kinetic and Potential Energy? In Physics, energy is used to refer to an ability to do work. Energy exists in various forms. This includes Gravitational energy, Chemical energy, Radiant energy, Mechanical energy, Sonic energy, Thermal energy, Nuclear or atomic energy, Magnetic energy and Electrical energy amongst many others.
Explanation:
The answer for this problem is clarified through this, the
system is absorbing (+). And now see that it uses that the SURROUNDINGS are
doing 84 KJ of work. Any time a system is overshadowing work done on it by the
surroundings the sign will be +. So it's just 12.4 KJ + 4.2 = 16.6 KJ.
The answer is in the image.
Answer:
2.29e-9C/m²
Explanation:
Using E = σ/ε₀ means the force on the electron is F = eE = eσ/ε₀.
The work done on the electron is W = Fd = deσ/ε₀. This equals the kinetic energy lost, ½mv².
½mv² = deσ/ε₀
d = 75cm – 15cm = 60cm = 0.6m
σ = mv²ε₀/(2de)
. .= 9.11e-31 * (7.4e6)² * 8.85e-12 / (2 * 0.6 * 1.6e-19)
. .= 2.29e-9 C/m² (i.e. 2.29x10^-9 C/m²)
