Answer:
power=400Watt
Explanation:
work done =12kJ=12×10³=12000j
time taken=30s
power=?
as we know that
power=work done/time taken
power=12000J/30s
power=400Watt
i hope this will help you :)
Answer:
Direction of the electric force acting on the proton after it enters the electric field is along the positive y-axis.
Explanation:
In an electrical field electrical field lines goes from positive to negative. Therefore, electrical force vector is on exactly the same way with electrical field lines for a proton. Which means if the electrical field directed along the positive y-axis, electrical force for proton will be on the same way.
Some commonly used techniques might be distillation and magnetism.
Distillation is basically a method of separating liquid mixture by basically boiling and condensing the different liquids. Since liquids don't have the same boiling points. one will evaporate first, and the other liquid or liquds will remaim.
Magnetism is a method of separating solid mixtures. One or some solids will get atracted to the magnet and the others will remain. Note that this only works if one of the solids has a magnetical property.
