Part 1 of 2: An ideal gas, initially at a volume of 6.22222 L and pressure of 9 kPa, undergoes isothermal expansion until its volume is 8 L and its pressure is 7 kPa. Calculate the work done by the gas during this process. Answer in units of J.
Part 2 of 2: Find the heat added to the gas during this process. Answer in units of J.
(a) The work done by the ideal gas during the isothermal exapnsion process is -3.556 J.
(b) The heat added to the gas during this process is 3.556 J.
Work done by the ideal gas
The work done by an ideal gas in isothermal expansion is change in pressure and volume of the gas. The change in the internal energy of the gas is zero.
The work done by the given ideal gas is calculated as follows;
W = ΔPV
where;
ΔP is change in pressure of the gasΔV is change in volume of the gasW = (P₂ - P₁)(V₂ - V₁)
W = (7kPa - 9kPa)(8L - 6.222L)
W = -3.556 kPa.L
1 kPa.L = 1 J
W = -3.556 J
Heat added to the processΔU = q + w
where;
ΔU is change in internal energy = 00 = q + (-3.556)
q = 3.556 J

a 65 kg climber on top of Mount Everest (8800 m high). what is the gravitational potential energy?
Answer:
He has 5,609,404 J of potential energy
Explanation:
P.E. = M*G*H
65 * 9.8^2 * 8800
The potential energy of the climber whos weight is 65 kg at a height of 8800 m is 5.6 × 10⁶ Joules.
What is Potential energy?The potential energy of a body is defined as that generated by virtue of its position which is the form of energy stored in an object when it is at rest. When a body stops its motion, its kinetic energy is converted into potential energy.
Potential energy is related to the mass 'm' and height 'h' of the object from the ground and the acceleration due to gravity g is expressed as:
PE = m g h.
For above given information, mass of the climber = 65 Kg
Height of the mountain = 8800 m
g = 9.8 m/s²
Thus, PE = 65 kg × 8800 m × 9.8 m/s² = 5.6 × 10⁶ Joules.
Thus, the potential energy of the climber will be 5.6 × 10⁶ Joules.

Which is an example of measurement that considers velocity? A the size of a standard basketball B the speed of baseball pitch C the placement of players on a field D the study of how records get broken
Answer: B, the speed of baseball pitch
Explanation:
The speed of a baseball pitch is an example of a measurement that considers velocity, therefore the correct answer is option B.
What is speed?The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is a meter/second.
average speed = total distance /Total time
The speed of the baseball pitch is an example of the measurement of velocity.
The size of a standard basketball is an example of the measurement of length.
similarly, option C and option d are unrelated to the measurement of the velocity.
The correct response is option B since a baseball pitch's speed is an example of a measurement that takes velocity into account.

A sample of helium behaves as an ideal gas as it is heated at constant pressure from 273 K to 388 K. If 80 J of work is done by the gas during this process, what is the mass of the helium sample? The universal gas constant is 8.31451 J/mol · K. Answer in units of g
The mass of the helium gas sample after the work is done by the gas during the process is 0.099 g.
Number of moles of the helium gasThe number of moles of the helium gas is calculated as follows;
W = nRT
where;
n is the number of molesW is the work doneR is universal gas constant = 8.31451 J/mol · KT is the final temperature = 388 K273 K = 0⁰C and 388 K = 115⁰ C
from 0⁰C to 115⁰C = 115 - 0 = 115⁰ C
115⁰ C = 388 K
The number of moles is calculated as follows;
n = W/RT
[tex]n = \frac{80}{8.315 \times 388} \\\\n = 0.0248 \ mol[/tex].
Mass of the helium sampleMass of the helium sample is calculated as follows;
m = Mn
where;
M is the molar mass of helium gas = 4 g/molm = 4 g/mol x 0.0248 mol
m = 0.099 g
Thus, the mass of the helium gas sample after the work is done by the gas during the process is 0.099 g.

Light can be passed through two slits and projected onto a screen. The light from the two light sources produces a pattern of dark and light spots on the screen. The spots can be the result of interference, which happens with waves but not particles. This shows that the wave explanation is best for explaining the spots.
What is the reasoning in this passage?
(1 point)
Light can be passed through two slits and projected onto a screen.
The light from the two light sources produces a pattern of dark and light spots on the screen.
The spots are the result of interference, which happens with waves but not particles.
This shows that the wave particle is best for explaining the spots.
The reasoning in the passage is : ( C ) The spots are the result of interference, which happens with waves but not particles
Light wavesLight passed through a slit and projected onto a screen will form a pattern which is very visible and the pattern might have dark spots if there is some form of interference. Interference is present in waves and not particles.

Without using a micrometer screw gauge, how do I find the average diameter of a long piece of thin wire using a metre rule and a uniform glass rod?
Answer:
Wind the long piece of thin wire around the uniform glass rod multiple times, find the length of the total diameters using the metre ruler, and divide by the number of times you wound it around the rod.
Explanation:
Since the diameter of one long piece of thin wire is too thin to be measured by a metre ruler, you can wind it multiple times and push it side by side to get a length you can measure.
For example, if you wound it around 20 times and the total length of 20 diameters of the wire side-by-side is 2.0 cm, one winding, which is the diameter would be 2.0cm ÷ 20 = 0.10cm or 1mm.

A particle moves in the xy plane in a circle centered on the origin. at a certain instant the velocity and acceleration of the particle are 6. 0 m/s and (3. 0 + 4. 0) m/s2. what are the x and y coordinates of the particle at this moment?
The x and y coordinates of the particle at this moment is (6x + 4.5y) m.
Position of the particleThe position of the particle at any instant is determined from the velocity and acceleration of the particle as shown below.
v² = u² + 2as
