Answer:

−1.9 × 10−5 Wb

Explanation:

Magnetic flux is the product of average magnetic field times the perpendicular area that is crosses times the angle between planar area and magnetic flux

Finding the area

Area = πr² = 3.14*0.075*0.075

Area=0.01767 m²

Magnetic flux = 0.01767*0.00110*cos 0

Magnetic flux =0.000019 = −1.9 × 10−5 Wb

Fittoniya [83]

Answer:

Q=7.9\times 10^{-10}\ C

Explanation:

Given that

V= 12 V

K=3

d= 2 mm

Area=5.00 $ 10#3 m2

Assume that

$ = Multiple sign

# = Negative sign

A=5\times 10^{-3}\ m^2

We Capacitance given as

For air

C_1=\dfrac{\varepsilon _oA}{d}

C_1=\dfrac{\varepsilon _oA}{d}

C_1=\dfrac{8.85\times 10^{-12}\times 5\times 10^{-3}}{2\times 10^{-3}}

C_1=2.2\times 10^{-11}\ F

C_2=\dfrac{K\varepsilon _oA}{d}

C_2=\dfrac{3\times 8.85\times 10^{-12}\times 5\times 10^{-3}}{2\times 10^{-3}}\ F

C_2=6.6\times 10^{-11}\ F

Net capacitance

C=C₁+C₂

C=8.8\times 10^{-11}\ F

We know that charge Q given as

Q= C V

Q=12\times 6.6\times 10^{-11}\ C

Q=7.9\times 10^{-10}\ C

mel-nik [20]

Answer:

Part a)

v = 0.0105 m/s

Part b)

E = 1.82 \times 10^8 J

Explanation:

As per momentum conservation we know that

P_1 = P_2

P_1 = m_1 v_1

P_2 = m_2v_2

here we know

m_1 = 6.00 \times 10^7 kg

v_1 =  ?

m_2 = 1100 kg

v_2 = 575 m/s

Part a)

now from above expression we can say

m_1v_1 = m_2v_2

(6.00 \times 10^7)(v) = (1100)(575)

v = 0.0105 m/s

Part b)

Now increase in the internal energy of the system

E = \frac{1}{2}m_1v_1^2 + \frac{1}{2}m_2v_2^2

E = \frac{1}{2}(6.00 \times 10^7)(0.0105)^2 + \frac{1}{2}(1100)(575^2)

E = 1.82 \times 10^8 J

The red shift of light from distant galaxies provides evidence that these galaxies are A.) decreasing in size B.) increasing in
ale4655 [162]

Answer: D.) increasing in distance from the earth

Explanation:

The <u>Doppler shift</u> is related to the Doppler effect and refers to the change in a wave perceived frequency (or <u>wavelength=color</u>) when the emitter of the waves, and the observer move relative to each other.

From there, it is deduced that the farther the object is, the more redshifted it is in its spectrum. For example, <u>as a galaxy moves away from the Earth, its espectrum turns towards the red and as the galaxy moves toward the Earth, its espectrum turns towards the blue. </u>

It should be noted that this effect bears its name in honor of the Austrian physicist Christian Andreas Doppler, who in 1842 proposed the existence of this effect for the case of light in the stars.
