Physics
1 answer:
mestny [16]3 years ago
7 0

Answer:

Physical conditions like temperature and pressure affect state of matter. ... When the pressure exerted on a substance increases, it can cause the substance to condense. Decreasing pressure can cause it to vaporize. For some types of rock, decreasing pressure can also cause them to melt.

The chemical equation below shows the reaction of methane (CH4) and oxygen gas (O2) to form carbon dioxide (CO2) and water (H2O)
Nuetrik [128]
<h2>Answer </h2>

Option C - Carbon Dioxide and Water

<u>Explanation </u>

The chemical equation reaction of methane (CH4) and oxygen gas (O2) to form carbon dioxide (CO2) and water (H2O).

CH4 + 2O2 → CO2 + 2H2O.

In this equation, carbon dioxide and water are products. Products are substances which are formed after a chemical reaction so in this case carbon dioxide and water are formed as a result after a chemical reaction. Therefore, these are products of reaction of methane and oxygen gas.

Ask Your Teacher A circular wire loop whose radius is 10.0 cm carries a current of 3.60 A. It is placed so that the normal to it
e-lub [12.9K]

Answer:

M=0.113\ Am^2

Explanation:

Given that,

Radius of the circular loop, r = 10 cm = 0.1 m

Current flowing in the loop, I = 3.6 A

Uniform magnetic field, B = 12 T

To find,

The magnetic dipole moment of the loop.

Solution,

Let M is the magnitude of magnetic dipole moment of the loop. We know that the product of current flowing and the area of cross section. Its formula is given by :

M=I\times A

A is the area of circular wire

M=I\times \pi r^2

M=3.6\ A \times \pi (0.1\ m)^2

M=0.113\ Am^2

Therefore, the magnetic dipole moment of the loop is 0.113\ Am^2. Hence, this is the required solution.

Fluid Dynamics links the concept of viscosity to the fluid flow. Mention how the contact angle, surface tension, capillarity gov
Elanso [62]

Fluid Dynamics is an area of ​​research that started a long time ago, along with Calculus. It combines techniques of Mathematical Analysis and of Dynamical Systems, such as Bifurcation Theory, among others.

<h3>What is surface tension?</h3>

Surface Tension is a phenomenon that occurs in all liquids, it is characterized by the formation of a kind of elastic membrane at its ends.

<h3>How to calculate the contact angle?</h3>

Contact angles in powders can be measured using the sessile drop measurement in the compressed powder or using the force tensiometer with the Washburn method.

In fluid dynamics, the variables of surface tension, viscosity and contact angle are treated. When dealing with viscosity we have  fluid can be viscous or a real fluid. In general, fluids are viscous.
