Why is it important to understand size, function and structure of the universe?

Two different MOS capacitors, with different gate-oxide thicknesses (3 nm and 15 nm), have the same density of positive oxide charge (Noc = 5 x 1010 cm-2) close to the oxide-semiconductor interface.

A runner generates 1260 W of thermal energy. If this heat has to be removed only by evaporation, how much water does this runner lose in 15 minutes of running? The latent heat of vaporization of water is 22.6 * 105J/kg.

StarsA. begin as protostars, which fire up when they collapse and become denser and hotter. B. create elements by splitting the nuclei of small atoms into the nuclei of larger atoms. C. have unlimited amounts of fuel and therefore exist indefinitely.

The units of electromotive force are

State the equation of momentum impulse theorem.

If the rock has a mass of 1 kg which is the speed of the rock after it has fallen for two seconds

2 Cars A and B both at rest are to set of from a town to a common destination along the same route. Car A was the first to take off and travelled at 2.

In an experiment to measure the acceleration due to gravity, g two values, 9.72 m/s2 and 9.67 m/s2, as determined. if the accepted value of g is: 9.8 m/s2 find the followings: i) the percentage difference of the measurements?

If momentum is conserved in a collision, does this indicate conclusively that the collision is elastic?

The acceleration of gravity means that for each second that passes, falling objects move 9.8 meters. A. True B. False
