To solve this problem we just need to use the rule of three:
150g..................395.1J
450g................xJ
x = 450*395.1/150 = 1185,3J
450.0 g of the substance completely reacted with oxygen will produce 1.1853 kJ(<span>kiloJoule</span>)
Which fractions are equivalent to 0.875?
Answer: 3.06m/s
Explanation:
Distance covered by swimmer = 220 m
Time taken by swimmer = 72 s.
Velocity = ?
Recall that velocity is the rate of change of distance per unit time. it is measured in metres per second.
Velocity = Distance / time taken
Velocity = 220m / 72seconds
Velocity = 3.055 m/s (approximate to 3.06m/s)
This is a true statement because the author can then be further looked into and researched
