In cosmology, a view that the universe is always expanding but maintaining a constant average density, with matter being continuously created to form new stars and galaxies at the same rate that old ones become unobservable as a consequence of their increasing distance and velocity of recession.

Answer:

A theory explaining the model of the Universe.

Explanation:

Steady State theory, proposed in 1948 by Sir Hermann Bondi, Thomas Gold, and Sir Fred Hoyle, suggests that the universe is always expanding while maintaining a constant average density. This is achieved as matter is continuously created to form new stars and galaxies at the same rate as that of old ones becoming non-observable. This occurs as a consequence of increasing distance and velocity of recession of old stars and galaxies.

As per this theory, Universe has no beginning and no end in time. If looked at it from a grand scale, the arrangement of galaxies and average density remain same.

Later observation of the Universe gave results contradictory to <em>Steady State Theory</em>. This has led to increase in support of <em>Big Bang Model</em> of the Universe.

Describe the benefits and risks associated with nuclear energy.
Ulleksa [173]

Producing nuclear energy is far more environmentally friendly than burning fossil fuels. That is the main benefit.

The main risk is radiation. If the nuclear waste is not properly disposed of, it can leak radiation into the environment. Fortunately, this is not an issue since there are ways to deal with it. There is also the risk of a disaster like the Chernobyl incident, however that was mostly due to faulty reactor construction. However, reactors today are built to avoid such issues.

Scientists usually write reports about their investigations. Why do they do this?
worty [1.4K]
As for me, the reson why scientists usually write reports about their investigations is because they want to <span>d. to communicate their work to other scientist. As far as I am concerned in this sphere they have to get many other opnions besides their own in order to complete or expand one that they have made up. Hope it helps :)</span>

23. A pogo stick has a spring with a force constant of 2.50×104N/m , which can be compressed 12.0 cm. To what maximum height can
tensa zangetsu [6.8K]

Answer:

The maximum height the child can jump on the stick

h=0.459m

Explanation:

Energy conservation

Energy kinetic = Work

The energy the child do get the height jump is proportional at the distance and the consta can be compressed so:

\frac{1}{2}*k*x^{2} =m*g*h\\k=2.50x10^{4} \frac{N}{m}\\x=12cm*\frac{1m}{100cm}=0.12m\\h=\frac{k*x^{2} }{2*m*g}\\h=\frac{2.50x10^{4}\frac{N}{m}*(0.12m)^{2} }{2*40kg*9.8\frac{m}{s^{2}}}\\h=\frac{360\frac{N}{m}m^{2} }{784N}\\h=0.459m

When you lift an object, you add the energy of lifting to the object.<br> Tor F
PtichkaEL [24]

It's true, when we lift an object we add energy to it.

because, when we lift an object by applying force , the object attains a height and hence the energy gets stored in it, in the form gravitational potential energy .
