Answer:
177.213 grams
Explanation:
Given:
Total amount of water = 364 grams
Latent heat of fusion = 333 kJ/kg
Heat transferred = 62.2 kJ
The amount of water frozen = 62.2/333 = 0.186786 kg = 186.786 grams
Hence, the amount of water remained unfrozen = Total water - Amount of water frozen
the amount of water remained unfrozen = 364 grams - 186.786 grams = 177.213 grams
Answer:
L = 2774.4 
Explanation:
Using the formula
L = mvr
Where L is angular momentum
m is mass
v is velocity
r is radius
m= 51kg , v=17m/s , r=3.2m
L = 51×17×3.2
L = 2774.4
A light-year is how astronomers measure distance in space.
-Light can travel 300,000 kilometres in one seconds!
Light year is the distance that light travel can travel in one year.
-Light can also travel 9,00,000,000,000 kilometers.
-One light is about 10 trillion km.
-Almost 300 years ago ,a Danish scientist named olaus roemer,was the fist man to estimate the distance light travels in a year -and using that he figure out the approximate speed of light!
