Answer:
44.85C
Explanation:
Let the specific heat of glass thermometer be 0.84 J/g°C
Let the specific heat of water be 4.186 j/g °C
Let the water density be 1kg/L
136 mL of water = 0.136L of water = 0.136 kg of water = 136 g of water
Since the change of temperature on the glass thermometer is 43.6 - 22 = 21.6 C. We can then calculate the heat energy absorbed to it:

Assume no energy is lost to outside, by the law of energy conservation, this heat energy would come from water




Answer:
C.) To indicate different versions of the same variable.
Explanation:
Variables in physics often include a subscript. These subscripts are used for indicating different versions of the same variable in physics.
Basically, subscripts are used to represent the beginning (initial) and ending (final) position or point of a variable in physics.
For example, we would look at Gay Lussac' Law of gases.
Gay Lussac law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Gay Lussac's law is given by;


Where;
represents the initial temperature.
represents the initial temperature.
represents the initial pressure.
represents the initial pressure.
Note: 1 and 2 are the subscript while T and P are the variables.
They start at 1 meter and after 10 seconds they've moved to 6 meters.
6 - 1 = 5 meters
Explanation:
It is given that,
The thinnest soap film appears black when illuminated with light with a wavelength of 535 nm, 
Refractive index, 
We need to find the thickness of soap film. The soap film appear black means there is an destructive interference. The condition for destructive interference is given by :

t = thickness of film
m = 0,1,2....
= refractive index


For thinnest thickness, m = 1


Hence, this is the required solution.
