Question

if X is the scale reading in a particular temperature scale , of x-lep by UFP-LEP= constant and s applicable​

Answer 1

Answer:

Given: LFP of the thermometer Y is 0

o

, UFP of the thermometer Y is 100

0

Solution:

Let us find the graph equation now, It is a straight line, so the equation will be of form y=mx+c.

The slope of the line is equal to m= tan45

0

, m = 1

The constant is the y coordinate when x is equal to 0.

Therefore, c=-10.

Now, the equation we get is,

y=x-10

Let us find the LFP of the thermometer X as Value of Y is given.,

y=mx+c

⟹0=x−10

⟹x=10

0

∴, the LFP of the thermometer X is 10 degrees.

Now, the UFP of the thermometer X can be founds similarly as,

y=x-10

⟹90=x−10

⟹x=100

0

Hence, the UFP of the thermometer X is 100 degrees.

Hence D is the correct option
