Ok I know this from other stuff potassium nitrate would completely dissolve in a 100 g on was at 30 c would be 60 but this is 40 so I’m not really sure and I don’t what to ok give you a bad grade but if I had to guess I would go with 65 grams
Answer:
Taking it was dropped with inital velocity of 0m/s.
v = u+at
v = 0 + 9.8*1.5
v = 14.7s
(a=9.8m/s^2 << That's the acceleration due to gravity)

Answer:
Explanation:
First ship starts at Noon with speed 20 Knots towards West
now we know that 2nd ship starts at 6 PM with speed 15 Knots towards North West
so after time "t" of 2nd ship motion the two ships positions are given as
now we can find the distance between two ships as
now we have
now we will differentiate it with respect to time
here we know that
so we have
now we have
Answer:
M. A change that causes the gene to increase the amount of lactase ir produces will increase a person's ability to break down lactose
Explanation:
Lactose is a sugar found in dairy products. Humans require an enzyme, called lactase, to break down the sugar in the body. This enzyme is produced by the lactase gene.
Some people have some variation in their gene that means they do not produce very much lactase. This means they do not produce sufficient amount of the enzyme to break down the sugar lactose found in milk. This causes them to feel ill and get abdominal pain when they eat dairy, because their body can't break down the sugar.
Therefore, a change in the gene that causes it to produce more lactase will make people more able to consume lactase. A change that decreases the amount of lactase enzyme will have the opposite effect.
The source of protein and minerals found in dairy are not processed by lactase, so R is not correct.
