The Law of Biot-Savart shows that the magnetic field of an infinitesimal current element decreases as 1/r2. Is there anyway you
Aleks04 [339]

Answer and Explanation:

There is no probability of obtaining such a circuit of closed track current carrying wire whose field of magnitude displays i.e.  B \alpha \frac{1}{r^2}

The magnetic field is a volume of vectors

And \phi\ bds = 0. This ensures isolated magnetic poles or magnetic charges would not exit

Therefore for a closed path,  we never received magnetic field that followed the B \alpha \frac{1}{r^2} it is only for the simple current-carrying wire for both finite or infinite length.

Binding of a signaling molecule to which type of receptor leads directly to a change in the distribution of ions on opposite sid
aalyn [17]

Binding of a signaling molecule to ligand-gated ion channel leads directly to a change in the distribution of ions on opposite sides of the membrane

<u>Explanation:</u>

The ligand-gated-ion-channel is trans membrane protein buildings that conduction course through the channel pores in light of the official of a neurotransmitter. They are not quite the same as voltage - gated - ion - channels, which are delicate to film possibilities, and G-protein coupled receptors (GPCR's), which utilize second messengers.

These ion channels, additionally ordinarily referred to as ionotropic receptors, are a gathering of trans membrane -ion-channel proteins which open to permit ions, for example, N a^{+}, K^{+} and potentially c l^{-} to go through the layer in light of the official of a synthetic errand person, for example, a neurotransmitter.

Find the period of a wave with a frequency 40 kHz​
Burka [1]

We know that frequency is an inverse value of time f=\dfrac{1}{t} this implies that time is the inverse value of frequency t=\dfrac{1}{f}.

Now since <em>f</em> is <em>40kHz</em><em>,</em><em> </em>we can calculate period or duration for that matter time.

t=\dfrac{1}{40\mathbf{kHz}}=0.000025\mathbf{s}=25\mathbf{\mu s}

Hope this helps.
