a super man I sitting on a tree 98m high with a he has rescued from a claws of a tiger. unfortunately the child shift and falls with an initial velocity of 0m/s supposed reached what was happened 2 second later and flow to catch the child at a speed of 39.2m/s find the time super man will fly before catching the child, and the distance super man fly to catch the child

What is the major limitation to the light microscope?

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c.m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
