Question:
The surface temperature of the filament in an incandescent light bulb is 1400 ∘C. If we double the current flowing through the light bulb without changing its resistance, what will the surface temperature become?

I'm confused on how to solve this. I thought of using ohm's law but I don't know how it could relate to temperature. Thanks

The surface temperature become 2092.9793°C

Explanation:

Given data:

T₁ = surface temperature of the filament = 1400°C = 1673 K

Double the current flowing through the light bulb

Question: What will the surface temperature become, T = ?

Increases the current by the double, increases the heat by four, and the temperature by 4^1/4 too.

answer: i don't know the answer good luck

explanation:

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
