Because your spaceship has an engine failure, you crash-land with an emergency capsule at the equator of a nearby planet. The planet is very small and the surface is a desert with some stones and small rocks laying around. You need water to survive. However, water is only available at the poles of the planet. You find the following items in your emergency capsule: • Stopwatch • Electronic scale • 2m yardstick • 1 Litre oil • Measuring cup Describe an experiment to determine your distance to the poles by using the available items. Hint: As the planet is very small, you can assume the same density everywhere.

Question

Because your spaceship has an engine failure, you crash-land with an emergency capsule at the equator of a nearby planet. The planet is very small and the surface is a desert with some stones and small rocks laying around. You need water to survive. However, water is only available at the poles of the planet. You find the following items in your emergency capsule:

• Stopwatch
• Electronic scale

• 2m yardstick
• 1 Litre oil
• Measuring cup

Describe an experiment to determine your distance to the poles by using the available items. Hint: As the planet is very small, you can assume the same density everywhere.
