As a result of doubled resistance, current will be halved.

As we know, Ohm's law inversely relates current and resistance to each other. The equation is as follows -

V = I*R, where V is voltage, I is current and R is resistance.

As the question mentions no change in any other parameter, let's assume I₁ and I₂ be initial and final current and R₁ and R₂ initial and final resistance.

So, R₂ will be 2R₁ as it is doubled.

Now, equating the values and finding out the value of final current.

I₁R₁ =  I₂R₂

Keep the value of R₂

I₁R₁ =  I₂2R₁

Cancelling R₁ as it is common on both sides of equation.

So, we get - I₁ =  2I₂

I₂ = I₁/2

Thus, as can be seen above, final current will be half of initial current.

The first law of thermodynamics describes how the heat added to a system is conserved. Heat the internal energy of the system or
worty [1.4K]

Answer: The first law of thermodynamics describes how the heat added to a system is conserved.

Explanation:

According to the first law of thermodynamics:  

<em />

<em>"Energy is not created, nor destroyed, but it is conserved."  </em>

Therefore, this law relates the work and the transferred heat exchanged in a system through the internal energy, which is neither created nor destroyed, <u>it is only transformed.  </u>

In other words: The change in the internal energy of a system is equal to the net heat that is transferred to it plus the net work done on it.

A wave has a wave length of 2 m and a frequency of 500 Hz, what is its speed?
Tomtit [17]
The wavelength, λ tells us how long one segment of the wave is.  The frequency, f tells us how often one whole segment goes by.  So the speed is the wavelength (in meters), times the frequency (in Hz)
v=λ f=1000m/s

Jake calculates that the frequency of a wave is 230 hertz, and its wave is moving at 460 m/s. What is the wavelength of the wave
Nesterboy [21]

Wavelength = (speed) / (frequency) = (460 m/s) / (230/sec) = <em>2 meters</em>
