In the real universe, no black holes contain singularities. In general, singularities are the non-physical mathematical result of a flawed physical theory.

Answer:

All black holes contain singularities, however not all singularities involve black holes. A neutron star may be dense, matter the size of a pinhead can weigh as much as the earth, but there seems to be a mathematical cut-off point beyond which a black hole is formed.

What homemade things could I use for wheels on a small balloon powered car?
Fantom [35]

You can use mostly anything as long as it is circular. Depending on how big it is, you could use sturdy paper plates and use a stick/rod and tape to hold it together, or you could use bottle caps if the car you are trying to make is really small.

Which of these galaxies would you most likely find at the center of a large cluster of galaxies?
Arada [10]

Answer:

b. a large elliptical galaxy

Explanation:

In elliptical galaxies the stars are grouped in an elliptical shape, it has a low quantity of gas and dust in comparison to spiral galaxies, and its stars belong to an old population, there is not new stellar formation in it.

The stars orbit in a messy way which made to believe that they form from the merger of galaxies.

They are also really massive (around 10^{4} solar masses).

The most massive and luminous can be found in the center of cluster of galaxies.

Calculate how much work is done when a force of 1600 N pulls a car through a distance of 40 m in the direction of the force.
Ulleksa [173]

Answer: work done = 64,000J or 64KJ.

Explanation:

Work is said to be done if a force applied makes the object to move through a distance in the direction of the applied force. Work is the product of force and perpendicular distance in the direction of the applied force. It is represented by W, measured in Joules(J) and a scalar quantity.

Thus, work done(J)= force(N) × distance(m)

From the the question,

applied force= 1600N

distance=40m

Therefore, work= 1600 × 40

W= 64,000J

But, 1 kilojoules = 1000J

Therefore, 64,000J = 64,000 ÷ 1000

= 64KJ

Work done is 64KJ
