A 120 gram egg moving at 17 m/s is stopped by catching it in a sheet. If the time to stop the egg is 0.18 seconds, what is the magnitude of the average force that stopped the egg? ​

Estimate the schwarzschild radius (in kilometers) for a mini-black hole formed when a superadvanced civilization decides to punish you (unfairly) by squeezing you until you become so small that you disappear inside your own event horizon. (assume that the your weight is 50 kg)

Smallest intensity of a stimulus that you can detect 50 percent of the time is
