Answer:
Option c) are perpendicular to the electric field
Explanation:
Equipotential surfaces are perpendicular to the electric field. the electric field lines are projected outwards from the equipotential surface, i.e., the lines of the electric field are at 90
to the equipotential surface.
Equipotential surface are those surfaces that have the same potential at any point on the surface. Thus the potential difference at any point on the surface is zero due to same potential.
Any charge particle on this surface will move in a perpendicular direction to the Coulombian force. No work is done by the force on a particle moving on an equipotential surface.
Answer:
Energy density will be 14.73 ![J/m^3](https://tex.z-dn.net/?f=J%2Fm%5E3)
Explanation:
We have given capacitance ![C=225\mu F=225\times 10^{-6}F](https://tex.z-dn.net/?f=C%3D225%5Cmu%20F%3D225%5Ctimes%2010%5E%7B-6%7DF)
Potential difference between the plates = 365 V
Plate separation d = 0.200 mm ![0.2\times 10^{-3}m](https://tex.z-dn.net/?f=0.2%5Ctimes%2010%5E%7B-3%7Dm)
We know that there is relation between electric field and potential
, here E is electric field, V is potential and d is separation between the plates
So ![E=\frac{V}{d}=\frac{365}{0.2\times 10^{-3}}=1825000N/C](https://tex.z-dn.net/?f=E%3D%5Cfrac%7BV%7D%7Bd%7D%3D%5Cfrac%7B365%7D%7B0.2%5Ctimes%2010%5E%7B-3%7D%7D%3D1825000N%2FC)
Energy density is given by
As an object falls from rest, its gravitational energy is converted to kinetic energy
G.P.E = K.E = mgh
K.E = (80 Kg)(9.8 m/s²)(30 m)
K.E. = 23,520 J
Answer:
Mass is the amount of matter in a object.
Explanation:
Answer:
small amounts of mass are converted to large amounts of energy
Explanation:
According to the mass-energy equivalence, which Albert Einstein initially proposed as a general principle. It was revealed that mass and energy are connected and that a "small amount of mass can be converted into enormous amounts of energy."
Using the formula E=mc^2. This means Energy equals mass times the speed of light squared.
Hence, it is true that "small amounts of mass are converted to large amounts of energy."
