A molecule is shown schematically. The distance from the center of the larger atom to the center of the smaller atom is d = 0.96, and the angle between the smaller atoms is θ = 105.6°. Find out the center-to-center distance between the smaller ato..
The minimum distance required to stop a car moving at 42.0 mi/h is 39.0 ft. What is the minimum stopping distance for the same car moving at 67.0 mi/h, assuming the similar rate of acceleration.
An Atwood machine consists of two masses, = 6.5 and = 8.5 , linked by a cord that passes over a pulley free to rotate about a fixed axis. The pulley is a solid cylinder of radius = 0.40 and mass 0.80 .
