The work done by the battery is equal to the charge transferred during the process times the potential difference between the two terminals of the battery:
where q is the charge and
is the potential difference.
In our problem, the work done is W=39 J while the potential difference of the battery is
, so we can find the charge transferred by the battery:
where q is the charge and
In our problem, the work done is W=39 J while the potential difference of the battery is
The distance from Buzău to Iaşi is 72 km. Find out the time a vehicle travels this distance if it has a speed of 72 km per hour. Expresses the speed in the unit of measurement in SI. I give the crown! Thank you
Answer:
3600seconds
Explanation:
Given parameters:
Distance = 72km
Speed = 72km/hr
Unknown:
Time it takes for the vehicle to travel the distance = ?
Solution:
Speed is the distance divided by time;
Speed =
time =
Insert the parameters;
time = = 1hr
The SI unit of time is in seconds;
3600 seconds is 1hr
The time is 3600seconds
