Gauss’s law of magnetism states that the net magnetic flux through any closed surface is zero.

vesna_86 [32]

Answer:

True

Explanation:

Gauss's law:

It is one of the Maxwell's equations which are the foundation of Electrodynamics. According to this law magnetic field has zero divergence and magnetic monopole can't exist. Inside a closed surface, the magnetic flux inward at the south pole will be exactly equal to the outward magnetic flux at the north pole of the magnetic dipole. Thus, the net magnetic flux will be zero.

Which statements describe elliptical galaxies? *Select the two correct answers.*

Alecsey [184]

Elliptical galaxies are galaxies that are shaped like an ellipse. An ellipse is oval in shape, which means elliptical galaxies are oval in shape.

The two correct statements that describe elliptical galaxies are:

B. They are the most common galaxy type.

C. They typically contain very little gas and dust.

Elliptical galaxies are galaxies where you will find little or no gas and dust. The galaxies that are numerous in number are the elliptical galaxies.

In the elliptical galaxy, you can't find any spiral component in it.

Therefore, from the above explanation, we can see that option B and C is the correct option.

The difference in potential between the accelerating plates of a TV set is about 24 kV. The distance between these plates is 1.5

ryzh [129]

Answer:

So electric field between the plates will be equal to $1600\times 10^3KN/C$

Explanation:

We have given potential difference between accelerating plates = 24 KV = 24000 volt

Distance between the plates d = 1.5 cm = 0.015 m

We know that potential difference is given by V = Ed, here E is electric field and d is distance between plates

So $24000=E\times 0.015$

E = 1600000 N/C = $1600\times 10^3KN/C$

So electric field between plates will be equal to $1600\times 10^3KN/C$

Three liquids are at temperatures of 6 ◦C, 23◦C, and 38◦C, respectively. Equal masses of the first two liquids are mixed, and th

kupik [55]

The equilibrium temperature is T13=3.12 ◦C

Explanation:

Given

The temperature of liquids: T1=6◦C, T2=23◦C, T3=38◦C

The temperature of 1+2 liquids mix: T12= 13◦C.

The temperature of 2+3 liquids mix: T23=26.8 ◦C.

The temperature of 1+3 liquids mix: T13= ??

1.When the first two liquids are mixed:

mC1(T1-T12)+mC2(T2-T12)=0
C1(6-13)=C2(23-13)=0
7C1=10C2
C1=1.42C2

2.When the second and third liquids are mixed:

mC2(T2-T23)+mC3(T3-T23)=0
C2(23-26.8)=C3(38-26.8)=0
3.8C2=12.8C3
C2=3.36C3

3.When the first and third liquids are mixed:

mC1(T1-T13)+mC3(T3-T13)=0
C1(6-T13)+C3(38-T13)=0
C1=1.42C2 C2=3.36C3
C1=1.42C2(3.36C3)
C1=4.77C3
C1(6-T13)+C3(38-T13)=0
4.77C3(6-T13)+C3(38-T13)=0
By solving the equation we get,
T13=3.12 ◦C
The equilibrium temperature is T13=3.12 ◦C
