Answer:

E=0.848

Explanation:

Given that

q= (94-p)²

where p is the price per case of tissues and q is the demand in weekly sales

As we know that price elasticity of demand given as

E=-\dfrac{dq}{dp}.\dfrac{p}{q}

q= (94-p)²

\dfrac{dq}{dp}=- 2 (94-p)

E=2 (94-p)\dfrac{p}{(94-p)^2}.

When p =  $28

E=2 \dfrac{p}{(94-p)}.

E=2\times \dfrac{28}{(94-28)}.

E=0.848

Two long parallel wires separated by 4.0 mm each carry a current of 24 A. These two currents are in the same direction. What is
lesya [120]

Answer:

Explanation:

Magnetic field at a a point R distance away

B = μ₀ / 4π X 2I / R where I is current

Magnetic field due to one current

=  10⁻⁷ x 2 x 24 / 1 x 10⁻³

48 x 10⁻⁴ T

Magnetic field due to other current

=  10⁻⁷ x 2 x 24 / 3x 10⁻³

16 x 10⁻⁴ T

Total magnetic field , as they act in opposite direction, is

= (48 - 16 ) x 10⁻⁴

32 x 10⁻⁴ T .

Two capacitors, C1 = 25.0 μF and C2 = 31.0 μF, are connected in series, and a 6.0-V battery is connected across them.a. Find the
Brrunno [24]

Answer:

13.83928\times 10^{-6}\ F

249.10704\times 10^{-6}\ J

137.89848\times 10^{-6}\ J

111.20842\times 10^{-6}\ J

2.98273 V

Explanation:

C_1=25\ mu F

C_2=31\ mu F

V = Voltage = 6 V

Equivalent capacitance is given by

\dfrac{1}{C}=\dfrac{1}{C_1}+\dfrac{1}{C_2}\\\Rightarrow C=\dfrac{C_1C_2}{C_1+C_2}\\\Rightarrow C=\dfrac{25\times 10^{-6}\times 31\times 10^{-6}}{(25+31)\times 10^{-6}}\\\Rightarrow C=13.83928\times 10^{-6}\ F

Equivalent capacitance is 13.83928\times 10^{-6}\ F

Energy stored is given by

E=\dfrac{1}{2}CV^2\\\Rightarrow E=\dfrac{1}{2}\times 13.83928\times 10^{-6}\times 6^2\\\Rightarrow E=249.10704\times 10^{-6}\ J

Total energy stored is 249.10704\times 10^{-6}\ J

Charge is given by

Q=CV\\\Rightarrow Q=13.83928\times 10^{-6}\times 6\\\Rightarrow Q=83.03568\times 10^{-6}\ C

Voltage is given by

V_1=\dfrac{Q}{C_1}\\\Rightarrow V_1=\dfrac{83.03568\times 10^{-6}}{25\times 10^{-6}}\\\Rightarrow V_1=3.3214272\ V

E_1=\dfrac{1}{2}C_1V_1^2\\\Rightarrow E_1=\dfrac{1}{2}\times 25\times 10^{-6}\times 3.3214272^2\\\Rightarrow E_1=137.89848\times 10^{-6}\ J

Energy strored in C1 is 137.89848\times 10^{-6}\ J

V_2=\dfrac{Q}{C_2}\\\Rightarrow V_2=\dfrac{83.03568\times 10^{-6}}{31\times 10^{-6}}\\\Rightarrow V_2=2.67857\ V

E_2=\dfrac{1}{2}C_2V_2^2\\\Rightarrow E_2=\dfrac{1}{2}\times 31\times 10^{-6}\times2.67857^2\\\Rightarrow E_2=111.20842\times 10^{-6}\ J

Energy stored in C2 is 111.20842\times 10^{-6}\ J

E=E_1+E_2\\\Rightarrow E=137.89848\times 10^{-6}+111.20842\times 10^{-6}\\\Rightarrow E=249.107\times 10^{-6}\ J

So, the energy is equivalent

Equivalent capacitance

C=C_1+C_2\\\Rightarrow C=25+31\\\Rightarrow C=56\times 10^{-6}\ F

E=\dfrac{1}{2}CV^2\\\Rightarrow V=\sqrt{\dfrac{2E}{C}}\\\Rightarrow V=\sqrt{\dfrac{2\times 249.107\times 10^{-6}}{56\times 10^{-6}}}\\\Rightarrow V=2.98273\ V

The voltage would be 2.98273 V
