Borgan's bicycle wheel has a raidus of 38 cm and is given an angular acceleration of 2.67 rad/s2 by applying a force of 0.35 n on the edge of the wheel. what is the wheel's moment of inertia

Why do scientists prefer the moment magnitude scale to the richter scale?

Light from the sun reaches Earth in 8.3min. The speed of light is 3.00 x 10^8 m/s. How far is the Earth from the sun?

Two identical massless springs of constant k = 200N/m are fixed at opposite ends of a level track, as shown. A 5 kg block is pressed against the left spring, compressing it by 0.15m. The block is then released from rest.

Which statements describe vectors? Check all that apply. - Vectors have magnitude only. - Vectors have direction only. - Vectors have both magnitude and direction. - Vectors are drawn using a curved line. - Vectors are drawn using an arrow.

Airplane releases a ball as it flies parallel to the ground at a height of 195m, the ball lands on the ground at exactly 195m from the release piont, calculate the speed v of the plane
