A resin tube and a PVC rod are both rubbed against styrofoam. Do
Ivan

The concepts of electrostatics allow us to find the result for the question about the electric forces in the two tubes is:

  • The tubes are attracted by having charges of different signs.

<h3>Electrostatics</h3>

Electrostatics studies the transfer of charge between bodies when they rub together, in generating the charges of the insulating bodies they are not mobile, so to transfer them from one body to another they must be in contact.

The force electric between charges is of two types:

  • Attractive. If the charges are of different signs.
  • Repulsive.  If  the charges are of the same sign.

The transferred charge depends on the bodies involved in the tables showns that the resin is positively charged when rubbed, the PVC acquires very little charge and polystyrene acquires a negative charge due to rubbing.

They indicate that the resin is rubbed with polystyrene, therefore the resin must acquire a positive charge and the polystyrene a negative charge.

Then the PVC is rubbed with the polystyrene, which initially we will assume neutral, the PVC does not acquire a charge and the polystyrenes acquires a negative charge, if the polystyrene is isolated from the ground, it shares this negative charge with the PVC, therefore the two materials remain with half of the negative charge.

Finally, we bring the resin, which is positively charged, closer to the PVC, which has a slight negative charge, therefore the two bodies must attract each other.

In conclusion using the concepts of electrostatics we can find the result for the question about the electric forces in the two tubes is:

  • The tubes are attracted by having charges of different signs.

A lion accelerates from 1.5 m/s to 1.0 m/s in 18.4 s. How far does the lion run during this time?
Lesechka [4]

Answer:

23 m

Explanation:

If acceleration is uniform then

distance = ( average velocity ) × time

              = ( (initial velocity +final velocity )/2 ) × time

              = (( 1.5 + 1.0) /2 ) × 18.4

              = ( 2.5/2 ) × 18.4

              = 1.25× 18.4

              =  23 m

The mass of the sun is 2*10^30 kg and its radius is
Marta_Voda [28]

Explanation:

Distance d=1.5×108 km=1.5×1011 m

Mass of the sun, m=2×1030 kg

Mass of the earth, M=6×1024 kg

Force of gravitation, F=G×d2m×M

F=6.7×10−11×(1.5×1011)22×1030×6×1024=3.57×1022 N
