I'm not sure about the distance to the nearest star, but it's probably about        4 light-years (L-y).

1 L-y = 1.86 * 10E5 mi/sec * 3600 sec/hr * 24 hr/day * 365 day/yr

1 L-y = 5.9 *10E12 mi   and 4 L-y = 2.3 *10E13 mi    distance to star

2.3 * 10E13 mi / 900 mi/hr = 2.6 * 10E10 hr       hours to star

2.6 * 10E10 hr / (24 hr/day) = 1.1 * 10E9 day     days to star

1.1 * 10E9 day / 365 day/yr = 3 * 10E6 yr = 3 million years to star

2. A package with a heat sink and fan has a thermal resistance to the ambient of 8 °C/W. The thermal resistance from the die to
Ronch [10]

To solve this problem it is necessary to apply the concepts related to the Power depending on the temperature and the heat transferred.

By definition the power can be expressed as

P = \frac{\Delta T}{\Delta Q}

Where,

\Delta T = T_m - T_a = Change at the temperature, i.e, the maximum acceptable die temperature (T_m) with the allowable temperature in chassis (T_A)

\Delta Q = Q_A-Q_D = Change in the thermal resistance to ambient (Q_A) and the Thermal resistance from die to package (Q_D)

Our values are given as,

T_m=110\°C

T_a= 50\°C

Q_A= 8\°C/W

Q_D= 2\°C/W

Replacing we have,

P = \frac{110-50}{8-2}

P = 10W

The power that can dissipate the chip is 10W
