Answer:
The melting point of a substance referst to the temperature at which it changes state from solid to liquid. Therefore, the statement "The melting point of glycerine is 13 degree celsius" means that when the temperature at which glycerine is subjected is equal or higher than 13 degree celsius, it changes state from solid to liquid.
For example, the melting point of water is 0 °C. It means that when the temperature is higher than 0°C water goes from solid (Ice) to liquid. We all have seen that, right? ✔️
Answer: 0.09 m
Explanation:
Centripetal acceleration in terms of tangential speed is:
where r is the radius.
It is given that,
centripetal acceleration of the mouse,
tangential speed ,
Radius of salami is:
Thus, the radius of the salami is 0.09 m.
Answer:
I think the answer must be A.
<span>Answer:
Using 1/f = 1/d' + 1/d ...(where d' object distance and d is image distance)
1/4 = 1/7 + 1/d
1/4 - 1/7 = 1/d
3/28 = 1/d
d = 28/3
d = 9.33 cm</span>
Answer:
V₂ = 2 L
Explanation:
given,
P₁ = 203 kPa
V₁ = 0.5 L
Now, volume is expanded
P₂ = 50.8 kPa
V₂ = ?
Using Boyle's law
P₁V₁ = P₂ V₂
inserting all the values
V₂ = 2 L
Hence, new volume of air in the pump is equal to 2 L.
