Answer:
reactants are needed to start a chemical reaction
Explanation:
am I correct
sense the time shown is increasing but the velocity is neither increasing or decreasing then the answer would have to be D.
<span>For this, you need a compass needle, an empty matchbox, two electric cells, some wires, a plastic bottle cap and the liquid which is to be tested. Keep the compass needle inside the empty tray of matchbox and wrap a couple of rubber bands around it. Connect the wires to the battery and insert two wires in the liquid which is kept in the plastic bottle cap. You will observe that when the current flows through the wire, there is deflection in the compass needle. This shows that the given liquid conducts electricity. In fact, magnetic compass needle can detect even feeble current. LED can also be used in place of compass needle.</span>
Answer:
Distance between two point charges, r = 0.336 meters
Explanation:
Given that,
Charge 1,
Charge 2,
Electric potential energy, U = -0.5 J
The electric potential energy at a point r is given by :
r = 0.336 meters
So, the distance between two point charges is 0.336 meters. Hence, this is the required solution.
