Q. T=277+4sThe temperature in kelvin, T, of a resistor in a circuit s seconds after connecting a battery is given by the equation. For how many seconds does the battery need to be connected for the temperature to increase by 1 kelvin?Choose 1 answer:(A) 0.25(B) 4(C) 69(D) 277
Given Equation: We are given the equation T=277+4s, where T is the temperature in kelvin and s is the time in seconds after connecting a battery. We want to find the value of s that corresponds to an increase of 1 kelvin in temperature.
Denote Initial Temperature: Let's denote the initial temperature as Tinitial. After an increase of 1 kelvin, the new temperature will be Tinitial+1. We can set up the equation Tinitial+1=277+4s to find the value of s that corresponds to this increase.
Set Up Equation: Since we are looking for the increase in temperature, we don't actually need to know the initial temperature. We can simply use the fact that the increase is 1 kelvin. So, we can write the equation as T+1=T+4s, where T is the initial temperature and T+1 is the temperature after the increase.
Subtract and Simplify: Subtracting T from both sides of the equation T+1=T+4s gives us 1=4s.
Find the Value: To find the value of s, we divide both sides of the equation 1=4s by 4, which gives us s=41 or s=0.25 seconds.
