Its most likely a combination of the bright lights and the air vents. It may also be just because you get tired or drowsy in stores.

When a nerve cell fires, charge is transferred across the cell membrane to change the cell's potential from negative to positive
goldenfox [79]

Answer:

The average current will be "17.69 nA".

Explanation:

The given values are:

Charge,

q = 9.2 pC

Time,

t = 0.52ms

The equivalent circuit of the cell surface is provided by:

⇒  i_{avg}=\frac{charge}{t}

Or,

⇒  i_{avg}=\frac{q}{t}

On substituting the given values, we get

⇒         =\frac{9.2\times 10^{-12}}{0.52\times 10^{-3}}

⇒         =17.69^{-9}

⇒         =17.69 \ nA

Your goal is to accelerate the particles to kinetic energy k. what minimum radius r of the cyclotron is required?
densk [106]
Considering the magnetic force is providing the centripetal force,
we get, mv^2/r = qvB
so, r = mv/qB

as the Kinetic energy, K of the particle is given by.5mv^2
so, v = sqrt(2K/m)
substituting the in radius equation,
<span>r = m*sqrt(2K/m)/qB

r = sqrt(2Km)/qB

A square coil, enclosing an area with sides 3.2 cm long, is wrapped with 2,720 turns of wire. A uniform magnetic field perpendic
marishachu [46]

Answer

\epsilon = -0.74\ V

Explanation:

given,                          

Side of square coil = 3.2 cm            

Number of turns = 2720                  

magnetic field in the coil increases to = 0.45 T

time interval = 1.7 s                  

average induced voltage in the coil = ?

length = 0.032 m                      

Area = 0.032² = 0.001024 m²

induced voltage                  

\epsilon = -NA \dfrac{dB}{dt}

\epsilon = -2720 \times 0.001024 \times \dfrac{0.45}{1.7}

\epsilon = -0.74\ V                          

The average voltage induced in the coil is equal to \epsilon = -0.74\ V
