The SI base units have the dimensions of: length, mass and time.

<h3>What are SI base units?</h3>

The SI base units are the internationally accepted system of units of fundamental quantities.

These SI base units consist of system of units of measurement starting with seven base units, which are as follows:

  • second (s): the unit of time
  • metre (m): The unit of length kilogram (kg): the unit of mass
  • ampere (A): the unit of electric current
  • kelvin (K): the unit oftemperature
  • mole (mol.): the unit of amount of substance
  • candela (cd):the unit of luminous intensity

Ask Your Teacher In the air over a particular region at an altitude of 500 m above the ground, the electric field is 120 N/C dir
strojnjashka [21]

Answer:

1.475\times 10^{-13}\ C/m^3

Explanation:

\epsilon_0 = Permittivity of free space = 8.85\times 10^{-12}\ F/m

A = Area

h = Altitude = 600 m

Electric flux through the top would be

-110A (negative as the electric field is going into the volume)

At the bottom

120A

Total flux through the volume

\phi=120-110\\\Rightarrow \phi=10A

Electric flux is given by

\phi=\dfrac{q}{\epsilon_0}\\\Rightarrow q=\phi\epsilon_0\\\Rightarrow q=10A\epsilon_0

Charge per volume is given by

\rho=\dfrac{q}{v}\\\Rightarrow \rho=\dfrac{10A\epsilon_0}{Ah}\\\Rightarrow \rho=dfrac{10\epsilon_0}{h}\\\Rightarrow \rho=\dfrac{10\times 8.85\times 10^{-12}}{600}\\\Rightarrow \rho=1.475\times 10^{-13}\ C/m^3

The volume charge density is 1.475\times 10^{-13}\ C/m^3

How is force useful as well as harmful.<br>Comment with the statement.​
vladimir1956 [14]

No, we can't say force is useful or harmful. All else being equal, force is either not harmful or useful depending on the body that is applying it and where it is applying it.

Given how it affects motion, force is a crucial idea. It is a relationship that, in the absence of an opposing force, modifies an object's motion. However, a push or a pull that any object feels is the simplest definition of force. Due to the fact that force is a vector quantity, it possesses both a magnitude and a direction.

How force is useful

A body at rest can move with enough force.A body in motion may be slowed down or stopped by it.It has the power to quicken the pace of an object in motion.Along with its shape and size, it can also alter the direction of a moving body.

How force is harmful

  • Force has the power to alter an object's state of motion.
  • Moving objects can shift direction due to force.
  • Moving things' speeds can be increased by force.
  • Moving items can become slower due to force.
  • Force has the power to alter an object's shape.
