all white dwarfs have masses in a small range—from about 0.5 to almost 1.4 malchemist sun symbol. why? (select all that apply.)

1 answer:

7 0

A white dwarf cannot support its own weight by its degenerate pressure if its mass is greater than 1.4 solar masses.

<h3>What are white dwarfs?</h3>

White dwarfs are stellar core remnant composed mostly of electron-degenerate matter.

White dwarf is very dense due to its large mass and smaller volume.

<h3>Reasons for comparable mass of white dwarfs and Sun</h3>

Stars with main sequence masses less than about 0.5 solar masses cannot ignite the helium fusion required to become white dwarfs.
A white dwarf cannot support its own weight by its degenerate pressure if its mass is greater than 1.4 solar masses.

A circuit is built based on this circuit diagram. What is the equivalent resistance of the circuit?

Dmitry_Shevchenko [17]

The three resistors are connected to the same points of the circuit, so they are in parallel configuration. The equivalent resistance of 3 resistors in parallel is given by:
$\frac{1}{R_{eq}}= \frac{1}{R_1}+ \frac{1}{R_2}+ \frac{1}{R_3}$
If we plug the values of the resistances into the formula, we find
$\frac{1}{R_{eq}}= \frac{1}{3.0 \Omega}+ \frac{1}{6.0 \Omega}+ \frac{1}{9.0 \Omega}= \frac{6+3+2}{18.0 \Omega} = \frac{11}{18.0 \Omega}$
From which we find the equivalent resistance:
$R_{eq} = \frac{18.0}{11} \Omega =1.6 \Omega$

So, the correct answer is B.

When the plutonium bomb was tested in New Mexico in 1945, approximately 1 gram of matter was converted into energy. Suppose anot

gayaneshka [121]

Answer:

The value is $E = 1.35 *10^{14} \ J$

Explanation:

From the question we are told that

The mass of matter converted to energy on first test is $m = 1 \ g = 0.001 \ kg$

The mass of matter converted to energy on second test $m_1 = 1.5 \ g = 1.5 *10^{-3} \ kg$

Generally the amount of energy that was released by the explosion is mathematically represented as

$E = m * c^2$

=> $E = 1.5 *10^{-3} * [ 3.0 *10^{8}]^2$

=> $E = 1.35 *10^{14} \ J$

On the 1-to-10-billion scale, about how far is it to the nearest stars besides the sun? on the 1-to-10-billion scale, about how

aliina [53]

Not sure what your question means but the nearest star is Alpha Centauri which is about 4.2 light years (ly) away. This is roughly 4x10¹³ km away. A billion is 10⁹ so this is 4x10⁴ larger than a billion. I'd say the last one then...

Which type of mirror causes light rays to refract away from each other?

Vikentia [17]

Mirrors don't cause refraction.

A convex mirror could cause parallel rays to REFLECT away from each other.
