Asmall metal bead, labeled a, has a charge of 26 nc . it is touched to metal bead b, initially neutral, so that the two beads share the 26 nc charge, but not necessarily equally. when the two beads are then placed 5.0 cm apart, the force between them is 4.4×10−4 n . assume that a has a greater charge. part a what is the charge qa and qb on the beads?

Explanation:

Given:

Using coulombs law the force between two charged particle is

where r is the radial distance between them

According to question we have

Hence the charge on two metal beads is calculated.

which three statements are true about all alloys?

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
