Answer:
3,333.33 /sec
Explanation:
frequency = 1/period
= 1/0.0003 = 3,333.33 /sec
Answer:
True
Explanation:
It is possible to reduce/lessen the force that is acting on an object. For example, if you were pushing on a box and wanted to push less on the box, that would be possible.
Answer:
Quantity of charge = 1800 Coulombs
Explanation:
Given the following data;
Current = 1 A
Time = 0.5 hours
Conversion:
1 hour = 60 * 60 = 3600 seconds
0.5 hour = 0.5 * 3600 = 1800 seconds
To find the charge passing through the wire;
Mathematically, the quantity of charge passing through a conductor is given by the formula;
Quantity of charge = current * time
Substituting into the formula, we have;
Quantity of charge = 1 * 1800
Quantity of charge = 1800 Coulombs
Answer:
0.5 hours or 30 minutes
Explanation:
each hour travels 80km
so, time taken= 40/80 hours
= 0.5 hours
= 30 minutes
