<span>6.6 degrees C
Let's model the student as a 125 w furnace that's been operating for 11 minutes. So
125 w * 11 min = 125 kg*m^2/s^3 * 11 min * 60 s/min = 82500 kg*m^2/s^2 = 82500 Joule
So the average kinetic energy increase of each gas molecule is
82500 J / 6.0x10^26 = 1.38x10^-22 J
Now the equation that relates kinetic energy to temperature is:
E = (3/2)Kb*Tk
E = average kinetic energy of the gas particles
Kb = Boltzmann constant (1.3806504Ă—10^-23 J/K)
Tk = Kinetic temperature in Kelvins
Notice the the energy level of the gas particles is linear with respect to temperature. So we don't care what the original temperature is, we just need to know by how much the average energy of the gas particles has increased by.
So let's substitute the known values and solve for Tk
E = (3/2)Kb*Tk
1.38x10^-22 J = (3/2)1.3806504Ă—10^-23 J/K * Tk
1.38x10^-22 J = 2.0709756x10^-23 J/K * Tk
6.64 K = Tk
Rounding to 2 significant digits gives 6.6K. So the temperature in the room will increase by 6.6 degrees K or 6.6 degrees C, or 11.9 degrees F.</span>
Answer:A the two wire will attract each other
Explanation:
When current is flowing in a wire it is surrounded by magnetic field whose direction can be given by right hand thumb rule.
If current is in direction of your thumb then wrapping of fingers will give the direction of magnetic field.
If two wires with current in same direction flows then the combined magnetic field will be constructive in nature and thus they attract each other.
force on second wire due to first wire is
which will be towards the first wire
Let <em>v</em> denote the initial speed of the ball. The ball's position at time <em>t</em> is given by the vector

The ball reaches the goal 13 m away at time <em>t</em> such that
at which point it attains a height of 2.44 m, so that
That's a pretty good intuitive definition of a <em>theory </em>.
