Hoochie [10]

Answer:

\frac{dy}{dt}=k(y_t-R)

Explanation:

According to Newton’s law of cooling, the rate of loss of heat from a body and the difference in the temperature of the body and its surroundings are proportional to each other.

\frac{dy}{dt}=k(y_t-R)

Here, y_t represents temperature at time t, R as the room temperature, t as the independent variable, y as the dependent variable.

12. An astronaut whose mass is 70 kg on Earth's surface 12 poi
Vadim26 [7]

Her mass is still 70 kg

Explanation:

The mass of an object is an intrinsec property of the object that gives a measure of the "amount of matter" inside the object.

Being an intrinsec property, it depends only on the object itself, not on its location: therefore, the mass of an object is always the same in different locations. Therefore, the mass of the astronaut in the spacecraft is still the same as if she was on the earth, 70 kg.

On the contrary, the weight of an object is the force of gravity acting on the object, and it is given by

F=mg

where

m is the mass

g is the acceleration of gravity

While m is always the same, the value of g changes based on the location: therefore, the weight of an object changes  depending on the location.

An experiment is designed to investigate the relation between the pressure and temperature in a tank that has a constant volume
viva [34]

Answer:

3rd order polynomial

Explanation:

Given that the increase in the order of the polynomial the error between the curve fit and measured data will decreases hence  :

The polynomial order that is best to use is the 3rd order polynomial, this is because using a 3rd order polynomial will produce a less variance and a low Bias
