An example of conductors of heat would be iron pans. a example of electric insulators would be copper, gold and silver. to contrast conductors and insulators, insulators let electricity pass through them while conductors restricts electricity. both conductors and insulators can work with lithium and sodium.
The power rating on the motor is the maximum power it's ABLE to deliver. It can run with LESS power output than the rating, but if you try to run it with MORE than it's rated, the motor will overheat and eventually burn out.
" 10 watts " means " 10 Joules of enrgy per second ".
If the motor is operated at its full maximum rated capacity, then
(500 joules) / (10 joules/sec) = <em>50 seconds</em>
Speed equals distance divided by time (Speed=Distance/Time).
For example if it takes someone three minutes to go three miles their speed is one mile a minute.
Answer:
Explanation:
electrical field strength = potential diff / distance
= ( 450 - 0 ) / 8 x 10⁻²
= 5625 V/m
b )
potential difference = electric field x distance
= 5625 x .10
= 562.5 V
Liquid to a gas hence the name water vapor
