what unseen or unheard or unfelt by humans{at least nobody i've ever met} do many animals ,cats and dogs particualuy, react to the coming of earthquakes before they actually happen.

So we all know no one knows what SHC is or works, but how can heat so intense it can vaporize flesh and turn bone be contained within a space so small that it somehow does not even burn up the extremeties of the body?

I've seen pics of SHC where a charred body would have vaporized while sitting on a couch, yet the couch is miracolously untouched and the limbs and head are unburned, even some clothing is intact. How can such an intense heat not spread so far that it combusts the entire room as well?

A small rock with a mass of 0.300 kg is released from rest at point A, which is at the top edge of a large, hemispherical bowl with a radius R = 0.560 m View Figure . Assume that the size of the rock is small compared to the radius of the bowl, so that the rock can be treated as a particle, and assume that the rock slides rather than rolling. The work done by friction on the rock when it moves from point A to point B at the bottom of the bowl is - 0.290 J.
What is the speed of the rock when it reaches point B? g = 9.81 m/s^2 for the acceleration due to gravity.

When its engine of power 75.0 kW is generating full power, a small single-engine airplane with mass 690 kg gains altitude at a rate of 2.10 m/s.
What fraction of the engine power is being used to make the airplane climb? (The remainder is used to overcome the effects of air resistance and of inefficiencies in the propeller and engine.)
g=9.80, express answer as a percentage

There is only theory available no hard evidence. I think that there is no black whole at the center of galaxies, I believe that the gravitational pull off all the stars at the center are pulling as well as pushing away. So stars are actually either being aborbed into bigger stars >> that's why its brighter toward the center >> or the more stars that are being pulled in toward the center of the galaxy are dancing around each other making the center of the galaxy spin faster >> from our perspective we cannot tell what's really going on at the center of the galaxy.

What do you think is really happening?

why is this? Unless I heard wrong. But there are instructions for earthquakes-stand in a doorway. Tornado-go to a basement or low area. Blizzards and hurricanes are relatively predictable. Lightning-if your hair starts to react-roll as tightly into a ball and remain low to the ground. If flash floods kill more people then why arent there any known precautions or emergency procedures for people to follow? I'm going to be looking for a place on a lake or river. I've been curious about this longer than plans to find waterfront. It just doesnt make sense to me.

Apparent Weight. A physics student weighing 600 N stands on a bathroom scale in an elevator. As the elevator starts moving, the scale reads 400 N.Find the magnitude of the acceleration of the elevator.
Take the free fall acceleration to be g = 9.80 m/s^2.

What is the magnitude of the acceleration if the scale reads 650 N? What direction is acceleration, down or up ?
