The formula to convert \ºC to \ºF is:

\ºF=\frac{9}{5}\ºC+32   (1)

and to convert \ºF to \ºC is:

\ºC=(\ºF-32)\frac{9}{5}(2)

Now, if we want to know at what temperature does the numerical value in \ºF match the numerical value in \ºC, we have to make \ºC=\ºF and solve any of both equations shown above.

Using (1):

\ºC=\frac{9}{5}\ºC+32

\ºC-\frac{9}{5}\ºC=32

-\frac{4}{5}\ºC=32

\ºC=-40

Using (2):

\ºC=(\ºC-32)\frac{9}{5}

\ºC-\frac{5}{9}\ºC=-\frac{160}{9}

\ºC=-40

1.67 N

Explanation:

Applying,

F = u(dm/dt)+m(du/dt) Equation 1

Where F = force, m = mass of the vehicle, u = speed.

Since u is constant,

Therefore, du/dt = 0

F = u(dm/dt) Equation 2

From the question,

Given: u = 10 m/s, dm/dt = 10 kg/min = (10/60) kg/s

Substitute these values into equation 2

F = 10(10/60)

F = 100/60

F = 1.67 N
