Differences between concave and convex meniscus​
BARSIC [14]

Explanation:

A concave meniscus,(normally seen) occurs when the molecules of the liquid are attracted to those of the container. This occurs with water and a glass tube. A convex meniscus occurs when the molecules have a stronger attraction to each other than to the container, as with mercury and glass.

If you start with a substance as a solid, what will happen to the molecules as you add thermal energy (heat)?
AveGali [126]

Answer:

C. molecules speed up as more thermal energy is added

Explanation:

The molecules will simply speed up as more thermal energy is added to the solid.

Thermal energy is a form of kinetic energy which is set in motion.

  • Heat causes kinetic energy build up in a body.
  • As the molecules of the solid gains heat, they will continue to increase in thermal energy.
  • They are forced to start vibrating about their fixed point.
  • Thereafter, when they have enough energy, they break free from the forces holding them.
  • Therefore, they move from a state of rest to one with a very high kinetic energy where the molecules moves rapidly.
  • This is why a solid will change to liquid and sometimes eventually gas

A large sheet of charge has a uniform charge density of 9  μCm2. What is the electric field due to this charge at a point just
Alex73 [517]

Answer:

Explanation:

Surface charge density, σ = 9 μC/m² = 9 x 10^-6 C/m²

According to the Gauss theorem,

Electric field due to the sheet is given by

E = \frac {\sigma }{2\epsilon _{0}}

E = \frac{9\times 10^{-6}}{2\times 8.854\times 10^{-12}}

E = 5.08 x 10^5 N/C
