(a)
The energy source for the motion of gas in the atmosphere.

Explanation of Solution
Introduction:
In atmosphere there are number of gases present. These gas molecules are in continuous motion.
Sun is the biggest source of energy for the motion of gases in atmosphere. If sunlight is not there, temperature of gas molecules decreases. Gas molecules may get converted into solid and liquid. It will get settle down on earth's surface.
Conclusion:
Solar energy is the source of energy due to which molecules of gas are in motion.

- The polar ice caps have a combined mass of about 2.65 × 1019 kg. If all of the ice in the polar ice caps melted, by how much time would the length of a day (Earth's rotational period) change? For simplicity, assume each ice cap is an identical thin solid disk with a radius of 7.20 x 105 m. Find the change both in seconds and as a percentage of duration of a day. change in time percent change (No Response) s (No Response) %arrow_forward. A space probe in outer space has a gyroscope within it used for rotation and stabilization. The moment of inertia of the gyroscope is I = 17.5 kg m² about the axis of the gyroscope, and the moment of inertia of the rest of the space probe is I = 5.00 × 105 kg • m² about the same axis. Initially both the space probe and gyroscope are not rotating. The gyroscope is then switched on and it nearly instantly starts rotating at an angular speed of 110 rad/s. How long (in s) should the gyroscope operate at this speed in order to change the space probe's orientation by 24.0°? (No Response) sarrow_forwardSolve thisarrow_forward
- Walking with a steady cadence is very important for covering long distances efficiently. How we place our feet, and how quickly we walk, also depends on the roughness of the surface we are walking upon and on the slope of the surface: we walk carefully on slippery surfaces, and take smaller steps when hiking up a hill. When we are walking at constant speed in a fixed direction, the horizontal and vertical components of the acceleration of our center of mass must be zero. In addition, the sum of torques about the body's center of mass must also be zero. Consider the situation shown in the figure below. ALMA XCM Х СМ XCM XCM XCM We can model the walking gait of a person as a swing of the front leg and torso about the point where the front foot is planted (shown with a red circle in the figure) and a rotation of the trailing leg about the center of mass (CM) of the person. If each leg of this 78.0 kg person is 85.0 cm long and has a mass of 13.8 kg, and 0; = 0₁ = 20.0°, what is the…arrow_forwardYou are attending a county fair with your friend from your physics class. While walking around the fairgrounds, you discover a new game of skill. A thin rod of mass M = 0.550 kg and length l = 2.80 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 = 1.20 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_forwardA 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 μ = 0.250. At the instant shown, the block is moving with a velocity of v; = 0.820 m/s toward the pulley. Assume that the pulley is free to spin without friction, that the rope does not stretch and does not slip on the pulley, and that the mass of the rope is negligible.

Two of the four quadriceps muscles, the vastis intermedius and the rectus femoris, terminate at the patellar tendon which is attached to the top of the tibia in the lower leg. The distance from the point of attachment of the patellar tendon to the rotation axis of the tibia relative to the femur is 4.10 cm in this athlete. a b (a) The two quadriceps muscles can exert a maximum force of 225 N through the patellar tendon.

- The angular momentum vector of a precessing gyroscope sweeps out a cone as shown in the figure below. The angular speed of the tip of the angular momentum vector, called its precessional frequency, is given by @p = t/L, where is the magnitude of the torque on the gyroscope and L is the magnitude of its angular momentum. In the motion called precession of the equinoxes, the Earth's axis of rotation precesses about the perpendicular to its orbital plane with a period of 2.58 × 104 yr. Model the Earth as a uniform sphere and calculate the torque on the Earth that is causing this precession.
