Physics and Computer Technology Quiz

The statement is false. When a bus moves at constant velocity, the penny would return to your hand due to inertia. However, if the bus accelerates or decelerates, the penny would NOT return to your hand because of inertia - it would continue at the original velocity while you and the bus change velocity. The penny's motion depends on whether the bus maintains constant velocity or accelerates.

Inertia is the tendency of objects to maintain their state of motion. This property is quantified by mass - mass is a measure of an object's resistance to changes in its motion. Objects with more mass have more inertia.

For an object moving in a straight line at constant speed, both the magnitude and direction of velocity remain unchanged. Acceleration is the rate of change of velocity, so zero change means zero acceleration.

To move at constant velocity (zero acceleration), the applied force must exactly balance the friction force. Since friction = 10 N, the applied force must also be 10 N to achieve net force = 0 (Newton's First Law).

Planets orbit the Sun due to gravity providing the centripetal force. If gravity disappeared, Newton's First Law states they would continue moving in a straight line (tangent to their orbit at that instant) with whatever velocity they had.

The first Celeron processors lacked L2 cache memory, which significantly reduced performance compared to Pentium II processors. This made them slower despite running at similar clock speeds. Later Celeron models added L2 cache and became much more popular.

The Windows Registry stored configuration data in two hidden files: USER.DAT (for user-specific settings) and SYSTEM.DAT (for system-wide settings). These files were located in the Windows directory. Autoexec.bat and config.sys were DOS-era files, while win.ini was a Windows 3.x configuration file.
