According to the formula of KE.

KE = 1/2m • v^2.

Both of the variables of mass and energy m determines an object's kinetic energy. Assuming the mass of an object is held constant, the change in velocity, or velocity change will dictate the amount of kinetic energy that a particular object posses.

The unit conversion between rankine and kelvin is (linear, exponential, quadratic, none of the above)?

diamong [38]

Answer:

Unit conversion between Rankine and Kelvin is linear.

Unit conversion between degree Celsius and degree Fahrenheit is linear.

Explanation:

Relation between rankine and Kelvin is

$R\ =\ \dfrac{9}{5}\ K$

So, the plot between Rankine and Kelvin is a straight line with zero intercept and has a slope having value $\dfrac{9}{5}$ .

Relation between degrees Celsius and degrees Fahrenheit is given by

$^{\circ}C\ =\ \dfrac{5}{9}\ (^{\circ}F\ -\ 32)$

So, the plot between degrees Celsius and degrees Fahrenheit is a straight line with slope $\dfrac{5}{9}$ and negative intercept of $\dfrac{160}{9}$ .
