When the object is launched into the air it has a kinetic energy proportional to its velocity squared. As it travels its energy is converted into gravitational potential energy as it slows down due to the...
The gold leaf will diverge from the metal stem. This is because connecting the negative electrode to the zinc plate, causes an influx of electrons to flow into the electroscope. When the electrode is remo...
The relevant equation to use in solving this problem, from Newton's law of gravitation, is Force = ( universal constant of gravitation x mass of earth x mass of moon)/ (distance between earth and moon sq...
A point in a gravitational field has an associated gravitational potential. It is defined as the work done required to bring a unit mass from a point an infinite distance to that point in the field. At an...
1/Rt=1/R1+1/R2R1=3+5=8R2=4Rt=1/(1/8+1/4)=8/3 Ohms = 2.67 Ohms (2 D.P.)
