Answer:
P = 359.8 atm
Explanation:
The van der Waals' equation relates the properties of a gas, introducing constants "a" and "b" in order to consider gases as real gases. The equation is:
where,
P: pressure
a: correction factor for intermolecular forces
V: volume
b: correction factor for molecules' volume
n: moles
R: ideal gas constant
T: absolute temperature
The image distance is 59.2 cm and the image is real and small.
<h3>
Image distance</h3>
The distance of the image formed by the convex or converging lens is determined by applying the following lens equation.
1/f = 1/u + 1/v
where;
- f is the focal length = 34 cm
- u is the object distance = 80 cm
- v is the image distance = ?
1/v = 1/f - 1/u
1/v = 1/34 - 1/80
1/v = 0.0294 - 0.0125
1/v = 0.0169
v = 1/0.0169
v = 59.2 cm
Thus, the image distance is 59.2 cm and the image is real and small.

The concept of a black hole seem reasonable to me because of its valid and authentic evidences.
<h3>What are the causes, characteristics, and major features of black holes?</h3>
A black hole is a region in space where light is unable to escape due to strong gravitation force. The strong gravity is formed because matter has been pressed into a tiny space. This compression occurs at the end of a star's life. Some black holes are formed when a stars die.
So we can conclude that the concept of a black hole seem reasonable to me because of its valid and authentic evidences.

The power output is 6500 J - ( 12% of 6500 J)
= 5460 J .
Is the first question complete? Because the work done by the river would be equal to work done by the axle of the wheel.
Answer:
<h2>B. 980 joules</h2>
Explanation:
Given the following data
initial temperature T1= 150 °C
final temperature T2= 250 °C
specific heat of gold c= 0.13 J/g°C
mass of gold m= 75.0 grams
we can use the expression stated below to solve for the quantity of heat
Substituting our known data into the expression we can solve for the value of Q
<em><u>The quantity of heat need to raise the temperature from 150°C to 250°C is 975 J</u></em>
