<h2>Answer: decreasing</h2>
An RC circuit is an electrical circuit composed of resistors and capacitors, where the charging time 
of the circuit is proportional to the magnitude of the electrical resistance 
and the capacity 
of the capacitor.
As shown below:
In this context, the electrical resistance is the opposition to the flow of electrons when moving through a conductor.
Therefore:
<h2>When a capacitor is being charged in an RC circuit, the current flowing through a resistor <u>decreases</u>.</h2>
And the correct option is b.
I think the correct answer from the choices listed above is option D. The model of the universe that suggests that the sun is the center of the universe was first brought by Copernicus. His model is known as the "Sun centered model".
A.Positive as work=force×distance (assuming that distance is always a constant) the work will always be positive as the force is always positive(this is because force=mass×acceleration where the acceleration is always positive unless the mass is being slowed down)
The speed of sound, c, is given by the Newton-Laplace formula
where
K = bulk modulus
ρ = density
Because the density is constant, the speed of sound is proportional to the square root of the bulk modulus.
Therefore when the bulk modulus increases, the speed of sound increases by the square root of the bulk modulus.
For example, if K is doubled, then
Answer:
If the bulk modulus increases by a factor of n, then c increases by a factor of √n.
I calculated on a sheet and used differentiation to solve the problems.
