The net force is 0 N.
To find the total net force, all you need to do is add the forces.
So 100 + -100 = 0
Most of these questions are trick questions, but if you know Newton's laws of forces, then you should know that all forces should cancel out with each other.
Hope this helps!!!
Contact and non contact forces are big factors to consider
in designing of different modes of transportation because this factors are
resistances for the mode of transportation. These contact and non- contact
forces should be minimized in order for the energy requirement to be also
minimum. But not the extent of risking the safety, for example a non contact
force is the wieght, the should be optimum, safety of the design should not be
compromised just to reduce weight, just like by removing essential parts,
support just to remove weight is not good.
<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:
C. Heat
Explanation:
HEAT is energy that is transferred due to a difference in temperatures.
I hope it helps! Have a great day!
