the answer would be B. the back emf increases, and the current drawn from the socket increases
more current is needed to make the motor move, like when you try to self crank a motor and the back wires are touching its harder to crank. and the emf increases since more current is being drawn in, strengthening the emf or increasing the emf
An additional 10ppm of methane will change the upward IR heat flux (in tropical
atmosphere) from 289.29 W/m2
to 286.211 W/m2
, which is a reduction of 3.08
W/m2
.
An additional 10ppm of CO2 will change the upward IR heat flux from 289.29 W/m2
to 289.29 W/m2
, which is a change of 0.13 W/m2
.
Therefore, an additional 10 ppm of methane would have a much larger impact on
the outgoing infrared flux than an additional 10 ppm of CO2 at current
concentrations
It equals 23.89.
Hope this helps!!
Answer:
In simple words, thermal equilibrium means that the two systems are at the same temperature.
Electromagnetic/Light waves travel at different speeds through different media.This results in refraction which gives the appearance of broken pencil to our eyes
