Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be create…

Chapter 11.5, Problem 11.CQ10P

A child walks across merry go-round A with a constant speed u relative to A. The merry-go-round undergoes fixed-axis rotation about its center with a constant angular velocity ω counterclockwise. when the child is at the center of A, as shown, what is the direction of his acceleration when viewed from above?
a. → b. ← c. ↑ d. ↓ e. The acceleration is zero.

The two disks A and B have a mass of 4 kg and 6 kg, respectively. They collide with the initial velocities shown. The coefficient of restitution is e = 0.75. Suppose that (VA)1 = 6 m/s, (VB)₁ = 7 m/s. (Figure 1) Determine the magnitude of the velocity of A just after impact. Determine the angle between the x axis and the velocity of A just after impact, measured clockwise from the negative x axis. Determine the magnitude of the velocity of B just after impact. Determine the angle between the x axis and the velocity of B just after impact, measured clockwise from the positive x axis. (VB)1 B (VA)1 60° Line of impact

A hot plane surface is maintained at 100°C, and it is exposed to air at 25°C.The combined heat transfer coefficient between the surface and the air is 25W/m²·K. (same as above). In this task, you are asked to design fins to cool asurface by attaching 3 cm-long, 0.25 cm-diameter aluminum pin fins (thermalconductivity, k = 237 W/m·K) with a center-to-center distance of 0.6 cm. (Tip:do not correct the length). Determine the rate of heat transfer from thefinned structure to the air for a 1 m x 1 m section of the plate.
