igor_vitrenko [27]
The periodic table is arranged in a way that trends are present in columns and rows. Elements belonging to the same column belongs to the same family which means they have the same properties. Elements belonging to the same row have the same number of electron shells. Example of elements with the same chemical properties are Na, Li, and K all belonging to the same group.

A railroad car of 2000 kg coasting at 3.0 m/s overtakes and locks with an identical car coasting on the same track in the same d
serg [7]
The key is in "they lock together". This tells you this is a complete inelastic collision and therefore you can use the formula:
m1*v1+m2*v2=v(m1+m2)
Plug in numbers:
2000*3+2000*2=v(2000+2000)
so v=2 m/s, obviously in the same direction of motion in which they were both moving.

An engine extracts 452.8kJ of heat from the burning of fuel each cycle, but rejects 266.7 kJ of heat (exhaust, friction,etc) dur
Svetlanka [38]

Answer: The thermal efficiency of the engine is 41.09 %.

Explanation:

Efficiency is the ratio of the useful work performed to the total energy expended or heat taken in.

Formula for thermal efficiency of engine is

\eta=1- \frac{Q_2}{Q_1}\times 100

\eta = efficiency

{Q_2} = heat rejected = 266.7 kJ

{Q_1} = heat extracted = 452.8 kJ

Putting in the values we get:

\eta=1- \frac{266.7 kJ}{452.8 kJ }\times 100

\eta=0.41\times 100

\eta =41.09\%

The thermal efficiency of the engine is 41.09 %.
