Determine the relations between masses
2... remote research
points
It’s note easy to obtain precise astrometric data about Mercury. Many errors were rooted out just after radioastronomical measurement on the 60’s. Let’s follow this work. Radioastronomers emit a signal towards Mercury at
3... Pinoccio's hat
points
Papa Carlo made a hat for Pinoccio from a thin metallic plate in the form of cone of height 20 cm with top angle of 60 degrees. Will this decoration keep itself on his head that could be imaged as a perfectly smooth ball of 15 cm diameter?
4... refrigerator
points
A refrigerator stands in a thermally insulated room, plugged in and switched on. After one hour of work we turn it off and let the room temperature stabilize. Find the differ-ence of this temperature from the original temperature.
P... water pendulum
points
A box vessel of a negligible mass has a square base of side length
- the vessel is absolutely rigid and the water freezes from the bottom,
- the vessel is elastic enough and the water keeps its cube form after freezing. The ice slides along the sides of the vessel, the distance
remains constant.
E... gravitation
points
Try to measure the free fall acceleration in as many different ways as possible. Carry out 10–20 measurements for each method, compare their results and their errors.
