Answer:
A full moon occurs when the Moon appears as a complete circle in the sky.
Explanation:
- We see it as a full orb because the whole of the side of the Moon facing the Earth is lit up by the Sun's rays.
- The moon shows no visible light of its own, so we only see the parts of the moon that are lit up by other objects.
Balance and graduate cylinder
The volume of the drum after chilled quickly is 3.6 L.
<u>Explanation:</u>
As per the Charles Law, for any gas at constant pressure, volume of the gas is in direct proportion with the temperature measured in Kelvin. As the temperature increases, the gas expands and vice versa.
![$\frac{V1}{T1} = \frac{V2}{T2} \\](https://tex.z-dn.net/?f=%24%5Cfrac%7BV1%7D%7BT1%7D%20%3D%20%5Cfrac%7BV2%7D%7BT2%7D%20%5C%5C)
After chilling the drum, the volume will get reduced and it can be found as,
V2 =
= ![$\frac{7.7 L \times 282 K}{598 K}](https://tex.z-dn.net/?f=%24%5Cfrac%7B7.7%20L%20%5Ctimes%20282%20K%7D%7B598%20K%7D)
= 3.6 L
Here the drum is chilled quickly, that is temperature is reduced and so the volume also decreases.
The properties of alloys most resemble metal. Copper, tin, fiberglass.
Answer:
91 millilitres
Explanation:
Recommended application = 65mg / Kg
This means 65 mg of dicyclanil per kg (1 kg of body mass).
Concentration = 50 mg / mL
How many millilitres required to treat 70kg adult?
If 65mg = 1 kg
x = 70 mg
x = 70 * 65 = 4550 mg
Concentration = Mass / Volume
50 mg/mL = 4550 / volume
volume = 4550 / 50 = 91 mL
