Answer 1 - The average kinetic energy of the particles of two pieces of iron at the same temperature and mass would be the same

Answer 2 - The particles of an object move FASTER when the temperature increases

Answer 3 - When a tight fitting lid is run under hot water, the lid

E/X/P/A/N/D/S as the temperature increases.

Answer 4 - I dont know sorry!

Answer 5 - What happens when something reaches absolute zero?

A student walks 30 feet to the right. Then walks 10 feet to the left. Then walks 20 feet to the right. It took 20 seconds to do

Harrizon [31]

Answer:

The students velocity is 3 ft/s

Explanation:

Velocity (ft/s)

Velocity is the Total distance covered over time taken to cover the distance. D/t

Overall movement to the right is the distance covered.

Total distance covered = 30 ft - 10 ft + 20 ft

= 40 ft

Time taken = 20 s

Students velocity = 40 ft / 20 s

Students velocity = 2 ft/s

It is desired to lay off certain horizontal distances for building layouts. The length of the tapes are not 100.00 ft. Determine

Elodia [21]

Answer:

725.44 by 180.11

Explanation:

If a 100-ft tape was used, the number of such tapes in 725 ft would be $\dfrac{725}{100}=7.25$

And in 180 ft would be $\dfrac{180}{100}=1.8$

The same number of tapes would be used for the incorrect tape to give the false dimension. This would be

$100.06\times7.25$ by $100.06\times1.8$ =

$725.44$ by $180.11$
