A constant magnetic field of 0.50 T is applied to a rectangular loop of area 3.0 × 10-3 m2. If the area of this loop changes fro
Nonamiya [84]

Answer:

e= 0.440 mV(millivolt)

Explanation:

Given Magnetic field B= 0.50T

A_{1}=3\times10^{-3}

A_{2}=1.6\times10^{-3}\\

Δt= 1.6sec

induced emf e=\frac{\mathrm{d} \phi }{\mathrm{d} t}

⇒e=B\frac{\mathrm{d} A}{\mathrm{d} t}

e=0.50\times\frac{3\times10^{-3}-1.6\times10^{-3}}{1.6}

e=0.440\times10^{-3} volt

e= 0.440 mV(millivolt)

9. From this lab, we learn that the electric field and electric potential depend on both, the magnitude of the source charge (q)
VARVARA [1.3K]

Answer:

the electric field and the electric potential increase 5 times

Explanation:

The electric field created by a point charge is

         E = k q / r²

in this case the charge changes from q₁ = 1 10⁺⁰ C to q₂ = 5 10⁻⁹ C

with the electric field is proportional to the charge

         E₅ = 5 E₁

the electrical power for a point charge is

         V = k q / r

as the electric power is proportional to the charge

         V₅ = 5 V₁

consequently both the electric field and the electric potential increase 5 times

How much did the pressure drop in the storm's center from November 9, 1200z, until November 11, 0000z
o-na [289]

The pressure dropped by 24 MB in the storm's center from November 9, 1200z, until November 11, 0000z.

Using the attached map below, in the morning of November 9, the pressure situated at the storm's center = 1000 MB isobar located at the center.

Meanwhile, on November 11, 0000z the pressure situated at the storm's center = 976 MB isobar  

The difference in this pressure is regarded as the pressure drop in the storm's center and it is determined as follows;

= 1000 MB - 976 MB

= 24 MB

Therefore, we can conclude that the pressure drop by 24 MB in the storm's center from November 9, 1200z, until November 11, 0000z.
