Question
Chapter 15, Problem 1FC
To determine
What positive value of Q and positive value of W represents in the first law of
Expert Solution & Answer
Answer to Problem 1FC
Positive value of Q represents the (c) system gains heat and positive value of W represents the work is done by the system.
Explanation of Solution
The expression of the first law of thermodynamics is,
Whenever the system gains the heat, the value of Q is positive. Similarly, the value of Q is negative whenever the system loses the heat.
If the work is done by the system, the value of W is positive. Similarly, the value of W is negative when the work is done on the system.
Conclusion:
Hence, the positive value of Q represents the (c) system gains heat and positive value of W represents the work is done by the system.

Hi,
Does Quantum physics theory means all branches for example quantum relativity, Quantum mechanics, Quantum field theory, and string theory? Can you explain each one of them?

Dear Scientist in physics , How are doing, my name is Yahya from Saudi Arabia and currently in my first semester to pursue Master's degree in physics. I have been watching all interviews of some scientists in physics on YouTube Channel and somthing has got my mind. I studied my bachelor 's degree in biology and I have been contacting Professor's Bruce Lipton many times and he explained epigenatic well. He was talking about physics many times. He said if you want to understand who we are and how we think, you need to understand Physics well. So I have decided to study physics. I have some questions : Why is the community of physics are divided? What is the difference between Quantum physics, quantum field theory, Quantim theory, and classical physics? What is quantum consciousness theory as well. What do they mean by wave function collapse? Why professor Roger's always has another opinions in quantum consciousness theory??
Best Regards,
Yahya
Given water's mass of 18g/mole and the value of the fundamental charge (charge magnitude of the electron and proton), use the largest charge density from the article to determine what fraction of water molecules became ionized (charged) due to triboelectric effects when it flows through the material that causes the largest charge transfer. Give your answer in e/molecule, or electrons transferred per molecule of water. For instance, a value of 0.2 means only one in five molecules of water loses an electron, or that 0.2=20% of water molecules become charged

- = A hanging weight, with a mass of m₁ = 0.365 kg, is attached by a rope to a block with mass m₂ 0.835 kg as shown in the figure below. The rope goes over a pulley with a mass of M = 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R₁ = 0.0200 m, and an outer radius of R2 = 0.0300 m; the mass of the spokes is negligible. As the weight falls, the block slides on the table, and the coefficient of kinetic friction between the block and the table is μk = 0.250. At the instant shown, the block is moving with a velocity of v; = 0.820 m/s toward the pulley.

A feedback mechanism senses the angular speed of the disk, and a drive motor at A ensures that the angular speed remain constant while a m = 1.20 kg block on top of the disk slides outward in a radial slot. The block starts at the center of the disk at time t = 0 and moves outward with constant speed v = 1.25 cm/s relative to the disk until it reaches the edge at t = 360 s. The sliding block experiences no friction. Its motion is constrained to have constant radial speed by a brake at B, producing tension in a light string tied to the block.

- (a) A planet is in an elliptical orbit around a distant star. At its closest approach, the planet is 0.670 AU from the star and has a speed of 54.0 km/s. When the planet is at its farthest distance from the star of 36.0 AU, what is its speed (in km/s)? (1 AU is the average distance from the Earth to the Sun and is equal to 1.496 × 1011 m.

While walking around the fairgrounds, you discover a new game of skill. A thin rod of mass M = 0.505 kg and length = 2.70 m hangs from a friction-free pivot at its upper end as shown in the figure. Pivot Velcro M Incoming Velcro-covered ball m The front surface of the rod is covered with Velcro. You are to throw a Velcro-covered ball of mass m = 1.25 kg at the rod in an attempt to make it swing backward and rotate all the way across the top. The ball must stick to the rod at all times after striking it. If you cause the rod to rotate over the top position (that is, rotate 180° opposite of its starting position), you win a stuffed animal. Your friend volunteers to try his luck. He feels that the most torque would be applied to the rod by striking it at its lowest end. While he prepares to aim at the lowest point on the rod, you calculate how fast he must throw the ball to win the stuffed animal with this…arrow_forward56 is not the correct answer!arrow_forward
