Which of the following represents the order (first to last In which they reach the bottom of the incline? Hoop, solid cylinder, solid sphere. solid cylinder, hoop, solid sphere. solid sphere, hoop solid cylinder. Solid cylinder, solid sphere, hoop. solid sphere, solid cylinder hoop. Which of the following has a speed of approximately 343 m/s? A sound wave traveling through air at room temperature. A world class sprinter at top speed. A car traveling at normal highway speed. A satellite in Low Earth Orbit (LEO). None of the Above. Which of the Moving parameters is conserved in an elastic collision between two objects?. Momentum Total Energy. Kinetic Energy. All of the above are conserved. None of the above are conserved. Which of the following quantities is not matched with its appropriate SI unit symbol? acceleration - m/s^2. angular velocity - rad/s work. - J force - W. All of the above are matched with their SI Units. An automobile tire is inflated to a gauge pressure of 32 0 psi (2.20 times 10^5 Pa). Which of the following quantities would have the highest value? Absolute pressure of the air within the tire. Gauge pressure of the air within the tire. Standard atmospheric pressure. All of the above have the same value. There is not enough information provided to determine the highest value.

Explanation / Answer

6] d is correct.

It is because solid sphere has least moment of inertia, so its rotational KE at bottom will be less, consequently translational KE will be more which causes higher speed.

So lower moment of inertia objects will reach first.
