Numa determinada escala X, arbitrária, um termômetro marca 0°X para o ponto de fusão do gelo e 50°X para o ponto de ebulição da água, ao nível do mar. Que temperatura esse termômetro marcaria se fosse mergulhado em um líquido cuja temperatura é de 50°C?

the temperature measured by the thermometer is 25 ° X

Explanation:

The computation of the temperature measured by the thermometer is shown below:

Here is the thermometric scale list

(X - 0) ÷  C - 0 = (50 - 0) ÷ (100 - 0)  

X ÷ C = 50 ÷100  

X = C ÷ 2  

Now if there is 50 degrees celcius

So, the x would be

= 50 ÷ 2

= 25 ° X

Hence, the temperature measured by the thermometer is 25 ° X

The same is to be considere d

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
