Diamond and graphite are both composed entirely of carbon yet graphite is soft and diamond is one of the hardest substances know

Explanation:

This difference is because of the difference in arrangement of carbon atoms both graphite and Diamond.

Carbon atoms in graphite are arranged in layered form in an infinite array of layers. These layers are held together by a weaker force of attraction called vander waal's force of attraction such that layer's can slip over one another. Whereas in diamond carbon atoms are arranged tetrahedrally. Each carbon atom is attached to four carbon atoms with a bond angle of 109.5°. It is strong rigid three dimensional structure that results in infinite array atoms. This accounts for hardness of the diamond.

In a given circuit, the supplied voltage is 1.5 volts. One resistor is 3 ohms and the other is 2 ohms. Use Ohm's law to determin
ozzi

You haven't said whether the two resistors are connected
in series or in parallel.  It makes a difference.

--  If they are in series, then their combined effective resistance is

                 (3 + 2) = 5 ohms.

Current in the circuit is    (voltage)/(resistance) = 1.5/5 = 0.3 Amp.


--  If they are in parallel, then their combined effective resistance is

               (3 x 2) / (3 + 2) = (6/5) = 1.2 ohms.

Current in the circuit is  (voltage)/(resistance) =  1.5/1.2 = 1.25 Amp.

Keep your lane position, and sound your horn while braking in a controlled manner. Sudden panic stops are not a good idea, as they could spook the animal, causing it to suddenly dart into the path of another vehicle.
