A curved line on a position/time graph shows that the speed is changing.
So right there, we know there is acceleration.
The atomic model has changed over time Scientists used the model to make predictions . Sometimes the results of their experiments were a surprise and they did not fit with the existing model Scientists changed the model so that it could explain the new evidence
Answer:
Explanation:
= Permittivity of free space =
A = Area =
d = Thickness =
k = Dielectric constant = 5.4
V = Voltage = 86.2 mV
Charge is given by
The charge on the outer surface is
Answer:True
Explanation:
By applying Gauss law Electric field is zero everywhere inside the conductor.
According to Gauss law the net flux of an electric field in a closed surface is directly proportional to the enclosed electric charge.
For example
For a Gaussian surface inside a conductor all the points have zero electric field as the system is in equilibrium. This implies net flux is zero and net charge inside is zero . So all the charge must be at surface on conductor.
Answer:
a variable (often denoted by x ) whose variation does not depend on that of another.
