Gravitational field can also be shown by lines of force. This is same in several ways as that of electric lines of forces. With one dissimilarity, electric charges are negative and positive which causes force of attraction among dislike charges and repulsion among like charges. While in phase of gravitation the force is always of attraction.
A line of force is drawn in such a way that at every point the direction of field is tangent to line that passes by the point. Thus tangent to any point on a line of force gives the direction of gravitational field at that position. Lines of forces are given in such a way that their density is proportional to the strength of field.
How a CPH does stop or its speed decreases? Answer; it is a principle that Vc is stable thus that; gradV c =0 Thus, never V c increases or decreases.
The current induced in the conductor due change in magnetic field is called eddy current.we study more about this in electro magnetic laws.
as flux = E.A and flux density is equal to flux/A then why A/A cannot e cancelled ?
#question.A tortoise can run with a speed of 0.12 m/s, and a hare can run 20 times as fast. In a race, they both start at the same time, but the hare stops to rest for 4.0 minutes.
what are unlike parallel forces with example?
The equation of reflected wave for soft boundary: y(x.t)=A cos[(wt-kx)] The equation of reflected wave for rigid boundary: y(x.t)=A cos[(wt+kx)] where A=amplitude of the wave
Draw the electric field figure as viewed by a person positioned on the positive x-axis who is looking back toward the origin for the case of an electric field characterized by the
Steel: Steel contains iron with a small percentage of carbon added it. Iron itself is not very strong but the additions of small percentage of carbon in it decrease the ductility
