Now, balance the equation:
in gaseous state exist as a diatomic molecule.
According to the formula you have given us to work with . . .
1). The airplane's acceleration is
(80 m/s north - zero) / (20 sec) = 4 m/sec^2 north
2). For the cyclist:
(V-final - zero) / 20sec = 0.5 m/s^2 south
Multiply each side by 20s : V-final = 0.5 m/s^2 south x (20sec) =
10 m/s south
Scandium lost 3 electrons and gave them to oxygen the formula would be Sc2O3
The answer is (3). The number of Sr is the same so if the compound has the smallest gram formula mass, it has the highest percent composition by mass of strontium. So the answer is (3).
Answer:
Solenoid having iron core.
Explanation:
Solenoid having iron core will pick up more paperclips because this solenoid will produce more electromagnetism. Solenoid having no iron core produces lower magnetic field as compared to solenoid having iron core. The presence of iron in the core of solenoid increases magnetic field which leads to increase in electromagnetism so that's why the solenoid with iron core attract more paperclips as compared to no iron core solenoid.
