One hundred turns of (insulated) copper wire are wrapped around a wooden cylindrical core of cross-sectional area 5.87 × 10-3 m2

Grace [21]

Answer:

The amount of charge that flow through a point is $\Delta q = 0.126 \ C$

Explanation:

From the question we are told that

The number of turns is $N = 100$

The area is $A = 5.87 *10^{-3} m^2$

The total resistance is $R = 14.9 \ \Omega$

The magnetic field in first direction is $B_1 = 1.93 \ T$

The magnetic field in second direction is $B_2 = -1.93 \ T$

The change in magnetic field is evaluated as

$\Delta B = B_1 - B_2$

substituting values

$\Delta B = 1.93 - [- 1.93]$

$\Delta B =3.2 \ T$

The induced emf due to the change is mathematically evaluated as

$e = NA \frac{\Delta B }{\Delta t }$

This can also be mathematically represented as

$e = IR$

Where I can be mathematically represented as

$I = \frac{\Delta q }{\Delta t}$

So

$e = \frac{\Delta q}{\Delta t } R$

Now

$\frac{\Delta q}{\Delta t } R = NA \frac{\Delta B }{\Delta t }$

=> $\Delta q = \frac{N A (\Delta B)}{R}$

substituting values

$\Delta q = \frac{100 * 5.87 *10^{-3} (3.2}{14.9}$

$\Delta q = 0.126 \ C$

A weather balloon has a volume of 90.0 l when it is released from sea level. What

frozen [14]

The final atmospheric pressure is $5.19\cdot 10^4 Pa$

Explanation:

Assuming that the temperature of the air does not change, we can use Boyle's law, which states that for a gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume. In formula,

$pV=const.$

where

p is the gas pressure

V is the volume

The equation can also be rewritten as

$p_1 V_1 = p_2 V_2$

where in our problem we have:

$p_1= 1.03\cdot 10^5 Pa$ is the initial pressure (the atmospheric pressure at sea level)

$V_1 = 90.0 L$ is the initial volume

$p_2$ is the final pressure

$V_2 = 175.0 L$ is the final volume

Solving the equation for p2, we find the final pressure:

$p_2 = \frac{p_1 V_1}{V_2}=\frac{(1.01\cdot 10^5)(90.0)}{175.0}=5.19\cdot 10^4 Pa$
