Pressure outside of a spacecraft is different from pressure inside the spacecraft. If it is not airtight. It will cause an explosion due to fast pressure change!

**Answer:**

7.6 %

**Explanation:**

As the first polarizer is oriented with a horizontal transmission axis so the light intensity passes through first polarizer is

The second filter has its transmission axis 25.7° from the horizontal so amount if light intensity passes through second polarizer is as so

Now the third polarizer is has vertical transmission axis so light intensity passes through third polarizer is as so

% so the 7.6 % of the light intensity passes through filter combination

With the information given, one can presume that:

Work = F • d (so W = 875,000 J)

The equation for power is:

P = W/t (so P = 19444.4 Watts)

1 Watt = 1000 Kilowatts

So the answer would be 19,444,444 kW

**Explanation:**

According to newton's second law of motion.

m is the mas of the sky diver = 93.4kg

a is the acceleration of the skydiver

From the formula above;

**Hence the acceleration of the sky diver is 1.563m/s²**
