Yuri [45]

Answer:

Nonmetals

Explanation:

Nonmetals typically lacks the metallic bonding which allows substances to exhibit metallic properties that confers special properties on them.

  • Metals are malleable and ductile
  • They are also able to conduct electricity due to the sea of electrons present within their structure.

Answer:

total disance covered by car=2858.11 meters

Explanation:

First calculate the time for which the given energy can be used

total energy=52700 joules;

756 joules used in every second;

Total time=\frac{52700joules}{756joules/sec}

total time=69.71 sec;

speed of car=41 m/s;

Number of meters the car travels= totaltime\times speed of the car

number of meters the car travels=69.71 \times 41

number of meers the car travel=2858.11 meters
