A piece of amber is charged by rubbing with a piece of fur. If the net excess charge on the fur is +8.0 nC (+8.0 10-9 C), how ma
Ann [662]

Answer:

Number of electron on the fur will be 5\times 10^{10}electron

Explanation:

We have given net charge on the fur q=8nC=8\times 10^{-9}C

Charge on one electron e=1.6\times 10^{-19}C

Let there are n number of electrons

So ne=8\times 10^{-9}

n\times 1.6\times 10^{-19}=8\times 10^{-9}

n=5\times 10^{10}electron

So number of electron on the fur will be 5\times 10^{10}electron

If an otherwise empty pressure cooker is filled with air of room temperature and then placed on a hot stove, what would be the m
Xelga [282]

Answer:

The magnitude of the net force F₁₂₀ on the lid when the air inside the cooker has been heated to 120 °C is \frac{135.9}{A}N

Explanation:

Here we have

Initial temperature of air T₁ = 20 °C = ‪293.15 K

Final temperature of air T₁ = 120 °C = 393.15 K

Initial pressure P₁ = 1 atm = ‪101325 Pa

Final pressure P₂ = Required

Area = A

Therefore we have for the pressure cooker, the volume is constant that is does not change

By Chales law

P₁/T₁ = P₂/T₂

P₂ = T₂×P₁/T₁ = 393.15 K× (‪101325 Pa/‪293.15 K) = ‭135,889.22 Pa

∴ P₂ = 135.88922 KPa = 135.9 kPa

Where Force = \frac{Pressure}{Area} we have

Force = F_{120}=\frac{135.9}{A}N.

The singularity at the center of a black hole is predicted to be a region of zero volume and infinite density that contains all
Reika [66]

Answer:

Yes

Explanation:

Science is a quest to find answers and patterns in the universe which can then be relied on for predicting future occurrence. Finding these singular points or at least to some extent, the cause and formation of this point will help with our further and deeper understanding of the universe, and we can then be able to predict when, where or when this singularities occurs.

Answer:

No

Explanation:

Spending a lot of time on these singularities that are hidden from view behind an event horizon that prevents any knowledge about the singularity reaching the outside universe is an absolute waste of time. This reflects no practice of science, since science is all about finding answers. If these answers we seek to find no matter how much we probe, cannot be gotten from further studies of these occurrences then it will be best to leave what can't be found. The fact that all known laws of physics breaks down at these point is a pointer that any physical means that will be employed to probe these singularities will yield no result within our known physical laws.

I will go with yes, with hope that advance in science will someday break these barriers or reconcile our known laws of physics with whatever physical law prevails within these singularities.
