(3x^3-2x^2+4x-8)-(5x^3+12x^2-3x-4)

n200080 [17]

Answer: $-2x^3-14x^2+7x-4$

Step-by-step explanation:

$(3x^3-2x^2+4x-8)-(5x^3+12x^2-3x-4)$

Distribute the negative sign.

$(3x^3-2x^2+4x-8)-5x^3-12x^2+3x+4$

Remove the other parentheses.

$3x^3-2x^2+4x-8-5x^3-12x^2+3x+4$

Combine like terms.

$-2x^3-14x^2+7x-4$

Alla [95]

Answer: (a) Magnetic flux before rotation is 7.2 × 10^-8 Wb and magnetic flux after rotation is 0

(b) The average emf induced in the coil is 3.6×10^-4 V

Step-by-step explanation:

Here is the complete question:

In a physics laboratory experiment, a coil with 200 turns en-closing an area of 12 cm2 is rotated in 0.040 s from a position where its plane is perpendicular to the earth’s magnetic field to a position where its plane is parallel to the field. The earth’s magnetic field at the lab location is 6.0×10^−5T. (a) What is the total magnetic flux through the coil before it is rotated? After it is rotated? (b) What is the average emf induced in the coil?

Before the industrial revolution in 1800 the concentration of carbon in Earth’s atmo- sphere was 280 ppm. The concentration in 2

slega [8]

Answer: There is increase of 4.255 in the amount of carbon in the atmosphere.

Step-by-step explanation:

Since we have given that

Concentration of carbon in Earth's atmosphere in 1800 = 280 ppm

Concentration of carbon in Earth's atmosphere in 2015 = 399 ppm

We need to find the percentage increase in the amount of carbon in the atmosphere.

So, Difference = 399-280 = 119 ppm

so, percentage increase in the amount of carbon is given by

$\dfrac{Difference}{Original}\times 100\\\\=\dfrac{119}{280}\times 100\\\\=\dfrac{11900}{280}\\\\=42.5\%$

Hence, there is increase of 4.255 in the amount of carbon in the atmosphere.
