current = charges / times (sec)
if a current of 2A flows for 8 hours(28800sec), then 2 * 28800 = 57600 coulombs of electrical charge move through the phone
I): Speed=Distance/Time
=65-30 km/12:30-12:00 hrs
=35 km/00:30hrs
=3500 m/1800 s
=1.94m/s
ii): Average Speed=Total Distance/Total Time
=100000 m/7200 s
=13.88 m/s
iii):No because it has different speeds at
different time intervals
Answer:
Conduction
Conduction is the movement of heat through a substance by the collision of molecules. At the place where the two object touch, the faster-moving molecules of the warmer object collide with the slower moving molecules of the cooler object.
