The reason why the position of an electron cannot be measured with absolute precision is:

A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

Consider a hydrogen atom in the ground state. what is the energy of its electron? =e= jj now consider an excited‑state hydrogen atom. what is the energy of the electron in the =5n=5 level? =e5= j
