Answer:
its point Y because the dot that represents Y is cose to s and can make a chan reaction
Your options are:
A) It is located at a distance of 2.6 million light years from Earth.
B) It has to travel a distance of 2.6 million kilometers to reach Earth.
C) It can be photographed by a space telescope in 2.6 million years.
<span>D) It has to move at the rate of 2.6 million kilometers per hour to reach Earth
You need to remember the definition of lightyear: one lightyear is the distance that light can travel in one year through space. It is a measure of astronomical distances and it is equal to 9.5×10¹²km.
Therefore, if light takes 2.6 million years to reach Earth, it means that the Andromeda Galaxy is at a distance of 2.6 million lightyears from Earth.
Hence, the correct answer is A) </span><span>It is located at a distance of 2.6 million light years from Earth.</span>
Answer:
Explanation:
As we know that at isochoric conditions if pressure of the gas is tripled then the temperature also becomes 3 times
So heat given in this process is given as
Now it is expanded to initial pressure again by adiabatic process
So in this part there is no heat exchange
Also we know that
Now in the last process we compressed the gas to original volume
Now total heat in the process is given as
Answer:
Explanation:
To solve this problem we will use the Ideal Gas Law, which forms the following formula
Where
= Pressure of Gas
= Volume of Gas
= Moles of Gas
= Constant = 0.0821 atm L/mol K
= Temperature of Gas
There are two states to consider
State 1 is given
= 0.741 atm
= 112 mL
= unknown
= 0.0821 atm L/mol K
= 300K
State 2 is based on Standard Room Temperature Pressure (STP) which are fixed values
= 1 atm
= unknown
= unknown
= 0.0821 atm L/mol K
= 273.15K
Since this is the same mass of gas it can be reasoned that the moles of gas are the same. We rearrange the Gas Law Formula to the following
We input the values and equate the formulas for both states by substituting the value of n
