How would you find the total energy stored in the

Physics
1 answer:
likoan [24]2 years ago
6 0

Answer:

The energy of the capacitors connected in parallel is 0.27 J

Given:

C = 2.0\micro F = 2.0\times 10^{- 6} F

C' = 4.0\micro F = 4.0\times 10^{- 6} F

Potential difference, V = 300 V

Solution:

Now, we know that the equivalent capacitance of the two parallel connected capacitors is given by:

C_{eq} = C + C' = 2.0 + 4.0 = 6.0\micro F = 6.0\times 10^{- 6} F

The energy of the capacitor, E is given by;

E = \frac{1}{2}C_{eq}V^{2}

E = \frac{1}{2}\times 6.0\times 10^{- 6}\times 300^{2} = 0.27 J

<h3>What is Quadratic equation ?</h3>

A quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2. The standard form of a quadratic equation is y = ax^{2} + bx + c, where a, b, and c are numbers and a cannot be 0

P(A) = 0.006 a^{2} - 0.02a + 120

123 = 0.006- 0.02a + 120

0=0.006 a^{2} - 0.02a - 3

you can use the quadratic equation  formula to solve for the man's age.

A = (-b ± (\sqrt{b^{2} - 4*a*c})  ) / (2a)

A = (0.02 ±  \sqrt{(-0.02)^{2} - 4*0.006*(-3)}/ (2*0.006)

A = (0.02 ± \sqrt{0.0076}) / 0.012

A = 9 , -5.67

Age of the man will be 9 years

A bucket that weighs 6 lb and a rope of negligible weight are used to draw water from a well that is 80 ft deep. The bucket is f
Tpy6a [65]

Answer:

The work done in pulling the bucket to the top of the well is 3,360 ft-lb

Explanation:

Given

Weight = 6 lb

Depth = 80ft

Weight of Water = 40lb

Rate = 2ft/s

Leak Rate = 0.2ft/s

Calculating Workdone to lift the bucket

Work = Force * Distance

Work = 6 * 80

Work = 480ft-lb

At time t, the bucket is xi = 2t above the original depth of 80ft.

t = ½xi

But it now holds 40lb - 0.2t lb of water

= 40 - 0.2(½xi)

= 40 - 0.1xi.

This is the size of the water when it is x ft above the original depth.

To move this amount of water, we need (40 - 0.1xi)∆x

So, W = ∫(40 - 0.1xi)∆x {1,n}

Where n = 80

W = ∫(40 - 0.1x)dx {0,80}

W = 40x - ½(0.1x²) {0,80}

W = 40x - x²/20 {0,80}

W = 40(80) - 80²/20

W = 3200 - 320

W = 2880 ft-lb

The work done in pulling the bucket to the top of the well = 2880 + 480

= 3,360 ft-lb
