No. of e- at a instant through given area is = total charge passing per
unit time/charge of e-
using i=q/t=(no.of e-(n))(1.6*10^-19)= 10
n=6.3*10^19 </span>
Answer. the curved speed time graph represents the non-uniform accelerated motion.
Answer:
a. push
Explanation:
Voltage is the force or pressure that is responsible for pushing the charge or electrons to flow in a closed-looped electrical circuit. This flow of electrons (charge) is called the electric current. It is also defined as the difference in electric potential per unit charge between two points in an electric field.
Answer:
Statement 1 and statement 2 are correct and statement 2 is the correct explanation of statement 1
Explanation:
Both the velocity and kinetic energy of a gas molecule depends on its relative molecular mass according to Graham's law of diffusion in gases. Hence, the greater the relative molecular mass of the gas, the lesser its average velocity and kinetic energy.
Hence we can see that statement 2 vividly explains the postulation of statement 1 and makes the points more easily comprehensible.
Answer:
613373.65233 m/s
Explanation:
M = Mass of Sun = 
m = Mass of Earth
v = Velocity of Earth
r = Distance between Earth and Sun = 
= Radius of Earth = 
= Radius of Sun = 
In this system it is assumed that the potential and kinetic energies are conserved
The velocity of Earth would be 613373.65233 m/s
