Answer:
Electromagnetism is the study of the electromagnetic force, one of the four fundamental forces of nature. It includes the electric force, which pushes all charged particles, and the magnetic force, which only pushes moving charges.It is used in many electrical appliances to generate desired magnetic fields. It is even used in a electric generator to produce magnetic fields for electromagnetic induction to occur.

Answer:
2.9 grams.
Explanation:
- From the balanced reaction:
<em>Mg + 1/2O₂ → MgO,</em>
1.0 mole of Mg reacts with 0.5 mole of oxygen to produce 1.0 mole of MgO.
- We need to calculate the no. of moles of (1.8 g) of Mg and (6.0 g) of oxygen:
no. of moles of Mg = mass/molar mass = (1.8 g)/(24.3 g/mol) = 0.074 mol.
no. of moles of O₂ = mass/molar mass = (6.0 g)/(16.0 g/mol) = 0.375 mol.
<em>So. 0.074 mol of Mg reacts completely with (0.074/2 = 0.037 mol) of O₂ which be in excess.</em>
<em></em>
<em><u>Using cross multiplication:</u></em>
1.0 mole of Mg produce → 1.0 mol of MgO.
∴ 0.074 mol of Mg produce → 0.074 mol of MgO.
<em>∴ The amount of MgO produced = no. of moles x molar mass </em>= (0.074 mol)(40.3 g/mol) = <em>2.98 g.</em>
Answer:
The sentences which are made by the given sentences are as :
Wind speeds are below 38 miles per hour, this feature represents the tropical depression.
Explanation:
Here in the question it has been mentioned to form the sentences with the given one:
- Wind speeds are below 38 miles per hour, this feature represents the tropical depression.
- A tropical disturbance leads to an array of clouds which are disorganized also there are thunderstorms with no rotation or little rotation with it.
- When the winds are blowing at a speed of 38 and 74 miles per hour then it is called as a tropical disturbance.
- 74 miles per hour should be the blowing speed of storm in order to consider it to be a Hurricane.
- When the storm reaches a tropical storm stage it gets its name.
- All of the storms which get occurred from time to time, among them half or even all get converted into a Hurricane.
These are the sentences which are made by exploring the whole process and by which a storm becomes a Hurricane.
