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.

the expression 15n + 2(3p) represents the amount isaiah spent buying gasoline and snacks, where n represents the price of each gallon of gasoline and p represents the cost of each snack that he bought. which statement is true about the amount isaiah spent?

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
