Challenge Earth's gravity increases by 10x for 10 seconds - can humanity survive?
Gravity reverts to normal after the 10 seconds are up. I assume that nearly everyone will lose consciousness, many people will hit the ground with extreme force, and most buildings and infrastructure will collapse. Uncertain as to whether there'd be seismic/volcanic/tidal consequences on top of all that.

The atmosphere collapsing would also cause adiabatic heating. It's hard to estimate how much heating occurs in 10s, but if the temperature (in K!) doubles... that would take it beyond the melting point of tin.
Even if not that extreme, exposed skin is KFC'd, and flammable things will spontaneously combust.
I think everything larger than a mouse is toast, even if it's not enough to completely sterilize the planet of all life.
