<span>When it comes to size Betelgeuse has the radius of 820.9 million KM where as Barnard is a smaller than Betelgeuse with 136,400 KM radius. In terms of color Betelgeuse is orange red and Barnard’s star is red in color. Lifetime wise Barnard’s star is one of the oldest stars, older than sun that is 7.12 billion years where as Betelgeuse is less than 10 million years.</span>

Betelgeuse is a class of Supergiant stars and they are 1000 times bigger than our own sun, they typically had 1000 radii. Barnard's stars  belongs to Main Sequence Star in which our sun belong. Our Sun is almost seven time larger than a Barnard's star. Barnard's star typically has only 0.15 Solar radii. Our Sun has 1.0 solar radii.

Which of the following affects the rate constant of a reaction?
Dennis_Churaev [7]
Arrhenius' equation relates the dependence of rate constant of a chemical reaction to the temperature. The equation below is the Arrhenius equation
k = Ae ^{{ \frac{-Ea}{RT} } } where k is the rate constant, T is the absolute temperature. As the temperature of the system increases, the rate constant also increases and vice versa.

Can anyone please tell me the properties of image formed in a spherical mirror?
notsponge [240]

Answer:

The two rays, CY and DM are diverging rays and when extended behind the mirror, they appear to intersect each other at point M'. Therefore, the properties of the images formed here are formed behind the mirror, between the pole and principal focus (f), the images are diminished and are virtual and erect.

Explanation:

<h2>Spherical Mirrors</h2>

  • There are two kinds of spherical mirrors, concave and convex.

  • The focal point (F) of a concave mirror is the point at which a parallel beam of light is "focussed" after reflection in the mirror. ...

  • The focal length (f) and radius of curvature (R) are defined in the diagram at the right.

How many moles of gas are in a 34.2 L container at 1 atm of pressure and 123℉?
slega [8]

Answer:

1.29 moles

0.753 moles

0.745 moles

Explanation:

PV=nRT

n=PV/RT

n=(1)(34.2)/(0.0821)(323.7)

n=1.29

n=PV/RT

n=(1)(22.4)=(0.0821)(362.15)

n=0.753

n=PV/RT

n=(1)(16.7)/(0.0821)(273.15)

n=0.745

In the ideal gas equation, T is measured in Kelvin.
