These are extremely rare and if you can find one which includes all parts and is in good working order, with the manual, then I would expect to pay around $US350 upwards. If it is in mint condition, or nearly so, then perhaps $US500.

Capacitance will block DC
Whats the job for a foam block

A transistor.
To effectively block microwaves from interfering with electronic devices, you can use materials that absorb or reflect microwaves, such as metal foils, metal mesh screens, or specialized shielding materials. Placing your electronic devices in a shielded enclosure or using a Faraday cage can also help block microwave interference.

The foam block is used to support the bell jar and create a seal with the baseplate. This helps to create a vacuum inside the bell jar by preventing air from entering or escaping during the experiment.
A bit is not a component of a PC, it is the building block of electronic programs.
Yes - even though there is an extremely small amount due to the block and air. In the experiment that is usually not taken into account even though strictly speaking it should be
To find the coefficient of dynamic friction, conduct an experiment by placing a block on a flat surface connected to a force sensor. Apply a horizontal force gradually to the block until it starts to slide, and note the force required for motion to begin. Use the formula: coefficient of dynamic friction = (force to start motion) / (weight of the block) to calculate the coefficient. Repeat the experiment multiple times to get an average value.
