Answer: The angle of resolution =47.05°
Explanation:
The angle of resolution represents the resolve power and precision of optical instruments such as the eye, camera and e en a microscope. It is given by the equation:
Sin A = 1.220(W÷D)
Sin A= 1.220(300÷500)
Sin A = 1.220(0.6)
Sin A = 0.732
A= Sin^-1 0.732
A= 47.05°
<u>Answer</u>
80 coils
<u>Explanation</u>
The turn rule of a transformer says that, the amount of voltage induced in the secondary coil is proportional to the number of coil. It is simplified by the ratio:
N<em>p/</em><em>N</em><em>s = </em><em>V</em><em>p/</em><em>V</em><em>s</em>
200/Ns = 25,000/10,000
200 × 10,000 = 25,000Ns
2,000,000 = 25000Ns
Dividing both sides by 25,000,
Ns = 2,000,000/25,000
= 80 coils
Cooking takes longer because water and other liquids evaporate faster and boil at lower temperatures.At sea level water boils at 212degrees Fahrenheit but at an altitude of 7,500 feet, it boils at about 198 degrees. Foods that are prepared by boiling or simmering will cook at a lower temperature and it will take longer to cook them. Hope this helps!! ; )
Answer:
P = 0.0644 atm
Explanation:
Given that,
The pressure of a sample of gas is measured as 49 torr.
We need to convert this temperature to atmosphere.
The relation between torr and atmosphere is as follow :
1 atm = 760 torr
1 torr = (1/760) atm
49 torr = (49/760) atm
= 0.0644 atm
Hence, the presssure of the sample of gas is equal to 0.0644 atm.
