Explanation:
Since compasses work by pointing along magnetic field lines, this means that there must be a magnetic field near the wire through which the current is flowing.
Answer:
Explanation:
Truck velocity=50 km/hr
police car velocity =45 km/hr
Let they start at t=0 s
After one hour
truck displacement
In vector Form
For Police car displacement
in vector form
Human activities is the main reason of global warming such as factories and cars that causes carbon dioxide , carbon monoxide and other toxic gases
The resistance is 4 times the resistance of the first wire. the formula is R = p*l/A with p being resistivity, l length and A area. So if you double length and half area, which botv result in more resistance, you get p*2/0.5 or 4 (p can be abandoned because it is the same. We take standard length and area as 1)
Answer:
analize the levels of kinetic and potential energy and look up a guide to graph it and follow that
