hodyreva [135]3 years ago
5 0

Explanation:

It's possible that before the Big Bang, the universe was an infinite stretch of an ultrahot, dense material, persisting in a steady state until, for some reason, the Big Bang occured. This extra-dense universe may have been governed by quantum mechanics, the physics of the extremely small scale, Carroll said.

Which two rocks are primarily composed of a mineral that bubbles with acid?
Marianna [84]
To most geologists, the term "acid test" means placing a drop of dilute (5% to 10%) hydrochloric acid on a rock or mineral and watching for bubbles of carbon<span> dioxide gas to be released. The bubbles signal the presence of carbonate minerals such as</span>calcite<span>, </span>dolomite<span>, or one of the minerals listed in Table 1.</span>

A brine is used to measure the absolute permeability of a core plug. The rock sample is 4 cm long and 3 cm 2 in cross section. T
nydimaria [60]

Answer : The absolute permeability is, 0.111 darcys.

Explanation : Given,

Volumetric constant rate = 0.5cm^3/s

Cross section area = 3cm^2

Pressure = 2 atm

Viscosity = 1.0 cp

Length of rock = 4 cm

From the Darcy equation  we conclude that,

\text{Volumetric constant rate}=\frac{(\text{Absolute permeability}\times A\times P)}{\eta \times l}

where,

A = cross section area

P = pressure

\eta = viscosity

l = length of rock

Now put all the given values in the above formula, we get:

0.5cm^3/s=\frac{(\text{Absolute permeability}\times 3cm^2\times 2\text{ atm})}{1.0cp \times 4cm}

\text{Absolute permeability}=0.111\text{ darcys}

Therefore, the absolute permeability is, 0.111 darcys.

If you had 1.00 kg of each kind of hardware, how many boxes of each would you<br> have?
dusya [7]

The number of boxes is calculated by dividing the

total mass of hardware boxes by 1.00 kg

<h3>What is a hardware?</h3>

A hardware is a physical component of a system that can be touched and felt.

Because hardware are physical components, they always have a given mass.

Assuming, several hardware each of mass 1.00 kg is available to be chosen from.

Also, assuming that the sum total of the mass of all the hardware is known.

The number of boxes can be calculated as follows:

  • total mass of hardware/1.00 kg

Therefore, the number of boxes is obtained by dividing the sum of the mass of the boxes by 1.00 kg.
