The nucleus of a particular atom as a diameter of 4.2 x10-15 m. for an electron to be confined within this region, the de broglie wavelength for the electron would have to have to be smaller than this diameter. assuming that the de broglie wavelength was equal to the nucleus diameter, what would be the kinetic energy of the electron in kj/mol? reminder: to specify large values (e. g. a billion) use scientific notation like so: 1e9 note: required precision is 2%.

gravititional force is a force that is acting around you, it is non-contactable and it is a force that pulls you to the core of the earth.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
