A certain parallel-plate capacitor is filled with a dielectric for which κ = 5.0. The area of each plate is 0.027 m2, and the pl

alexdok [17]

Answer:

Energy will be $4.776\times 10^{-5}J$

Explanation:

We have given that dielectric constant k = 5

Area of the plate $A=0.027m^2$

Distance between the plates $d=2mm=2\times 10^{-3}m$

Electric field E = 200 kN/C

We know that capacitance is given by $C=\frac{K\epsilon _0A}{d}=\frac{5\times 8.85\times 10^{-12}\times 0.027}{2\times 10^{-3}}=0.597\times 10^{-9}F$

We know that electric field is given by $E=\frac{V}{d}$

So $V=Ed=200\times 10^3\times 2\times 10^{-3}=400volt$

So energy will be $E=\frac{1}{2}CV^2=\frac{1}{2}\times 0.597\times 10^{-9}\times 400^2=4.776\times 10^{-5}J$

A 57-gram tennis ball moving at 70 miles per hour is hit with a 110-gram tennis racquet moving at 60 miles per hour. Which state

Whitepunk [10]

Answer:

D. Because mass and energy are both conserved, the total amounts of mass and energy are the same before and after impact.

Explanation:

As we know that, the energy in motion is Kinetic Energy mathematically given as:

$KE=\frac{1}{2} m.v^2$

<u>Now, according to the law of conservation of energy:</u>

$\frac{1}{2} m_1.u_1^2+\frac{1}{2} m_2.u_2^2=\frac{1}{2} m_1.v_1^2+\frac{1}{2} m_2.v_2^2$

where:

$m_1\ \&\ m_2$ mass of racquet and ball respectively and $u_1\ \&\ u_2$ are their respective initial velocities.

$v_1\ \&\ v_2$ are the respective final velocities.

<u>Also the law of conservation of momentum is applicable in this case:</u>

$m_1.u_1+ m_2.u_2= m_1.v_1+m_2.v_2$

In this case the velocity of the lighter mass will get increases in the final condition.
