The main morphological types of galaxies are elliptical, spiral, and irregular.

Based on their morphology , galaxies have been classified into 3 types namely elliptical, spiral, and irregular.

These galaxies have various sizes and shapes ranging from dwarf galaxies to giant galaxies.

Elliptical Galaxy:

The shape of it is generally circular
These are the largest among all the types of galaxies because according to astronomers, it is formed by the merger of other small galaxies.
Their rotational pattern is symmetric.

Spiral Galaxy:

A spiral galaxy consists of a bright nucleus surrounded by a thin outer disk forming a spiral shape.
This type of galaxy is the most common in our universe.
It is divided into three classes: Spiral a, Spiral b, and Spiral c.
Their rotational pattern has circular symmetry.

Irregular Galaxy:

These types of galaxies have no central nucleus and irregular arms which are bluish.
They don’t have any rotational symmetry.

Answer:

rotating movement on itself, it creates the phenomenon of day and night.

Explanation:

When a body that rotates around a star (translational movement), rotates on itself (rotational movement), the light from the star cannot reach the opposite part of the object, so at these points it is NIGHT and when in the rotation movement the point is in front of the star it is DAY.

Therefore, in rotating movement on itself, it creates the phenomenon of day and night.

The rate at which a metal alloy oxidizes in an oxygen-containing atmosphere is a typical example of the practical utility of the

Ray Of Light [21]

Answer:

The activation energy is $Q = 328.31 \ K J/mol$

Explanation:

From the question we are told that

The rate constant is k

at the temperature $T_1 = 300 = 300 + 273 = 573 \ K$

The value of k is $k_1 = 1.05 *10^{-8} \ kg /m^4 \cdot s$

at temperature $T_2 = 400 ^oC = 400 + 273 = 673 \ K$

The value of k is $k_2 = 2.95 *10^{-4} \ kg /m^4 \cdot s$

The rate constant is mathematically represented as

$k = Ce^{- \frac{Q}{RT} }$

Where Q is the activation energy

R is the ideal gas constant with a value of $R = 8.314 \ J /mol \cdot K$

C is a constant

T is the temperature

For the first rate constant

$k_1 = Ce ^{-\frac{Q}{RT_1} }$

For the second rate constant

$k_2 = Ce ^{-\frac{Q}{RT_2} }$

Now the ratio between the two given rate constant is

$\frac{k_1 }{k_2} = e^{(\frac{Q}{R} [\frac{1}{\frac{T_2 - 1}{T_1} } ] )}$

=> $ln [\frac{k_1}{k_2} ] = \frac{Q}{R} * [\frac{1}{\frac{T_2 -1}{T_1} } ]$

substituting values

$ln [\frac{1.05 *10^{-8}}{2.95 *10^{-4}} ] = \frac{Q}{8.314} * [\frac{1}{\frac{673 -1}{573} } ]$

=> $Q = 328.31 \ K J/mol$

Which of the following is an example of benefits?

dangina [55]

Insurance would be a example of benefits because you don’t receive insurance like you would salary, salary is a base thing you receive when you get a job while insurance you only get as a benefit with certain jobs

The answer would be “B” because humans would need water, protection from radiation so we don’t melt or burn to death lol, and a gaseous atmosphere because we would need oxygen.
