Answer:
Explanation:
Initial volume v₁ =46 x 10⁻⁶ m³
Initial temperature T₁ = 438.28 + 273 = 711.28 K
Initial pressure P₁ = nRT₁ / v₁
= 30.4 x8.3 x 711.28 / (46 x 10⁻⁶ )
= 3901.5 x 10⁶ Pa
Final temperature T₂ = 824 + 273 = 1097 K
Final volume V₂ =?
For isobaric process
v₁ / T₁ = V₂ / T₂
V₂ = V₁ X T₂ /T₁
= 46 X 10⁻⁶ X 1097/ 711.28
= 70.94 X 10⁻⁶ m³ = 70.94 cm³
b ) For isothermal change
P₁ V₁ = P₂V₂
P₂ = P₁V₁ / V₂
= 3901.5 X 10⁶ X 46 / 24.3
7385.55 X 10⁶ Pa.
Answer:
66.98 db
Explanation:
We know that
L_T= Total signal level in db
n= number of sources
L_S= signal level from signal source.
= 66.98 db
Answer:
The average density of the rod is 1.605 kg/m.
Explanation:
The average density of the rod is given by:
To find the average density we need to integrate the linear density from x₁ = 0 to x₂ = 3, as follows:
(1)
Using u = x+1 → du = dx → u₁= x₁+1 = 0+1 = 1 and u₂ = x₂+1 = 3+1 = 4
By entering the values above into (1), we have:
Therefore, the average density of the rod is 1.605 kg/m.
I hope it helps you!
Objects 1 and 2 attract each other with an electrostatic force of 72.0 units. if the charge of object 1 is halved, then the electrostatic force is 36.0 units
Let's understand the answer
The electrostatic force is the force that exists between two charged particles which is given by:
where
k is the Coulomb's constant
q1 and q2 are the two charges
r is the distance between the charges
In this problem, the charge of object 2 is doubled, so
So, the electrostatic force will be halved.
Since as the initial electrostatic force is
F = 72.0 units
the new force will be
72/2 = 36 units

Dry air adjacent to the cloud is entrained air is drier than the air within a cloud. The evaporation occurs in the cloud which cools the air. The cooling of air increases its density and creates a downdraft.
<h3>How clouds are formed?</h3>
A cloud can be described as a mass of ice crystals or water drops suspended in the atmosphere. Clouds can be formed when the water condenses in the atmosphere. The sky possesses some quantity of water vapours and it is invisible to us.
Clouds can be formed when an area of air gets cooler until the water vapour there condenses to liquid form. At this point, the air gets saturated with water vapours.
A cloud can never be perfectly adiabatic. Therefore, after mixing the environmental air with the clouds, its boundaries will not stay well defined and this process is called entrainment.
