The force of gravity is when the distance between two objects is d is:
F=(G*m1*m2)/d^2
Step-by-step explanation:
y = -9x - 45 -5
y = -9x - 50
slope = x coefficient = -9
we can use the point where
x = 0
y = -50
P1 (0, -50)
and when y = 0
-9x = 50
x = -50/9
P2 = (-50/9 , 0)
Answer:
a) Ans: 8.5 miles per hour
b) Ans: 46.75 miles
Step-by-step explanation:
a) Speed = Distance/Time
8.5/1h = 8.5 miles per hour
b) Distance = Speed x Time
8.5 miles per hour x 5.5h = 46.75 miles
She returned the bottle of 250 milliliter in lithium stock where another 175 milliliter of lithium was already present in the stock.
Quantity of lithium before return = 175 milliliter.
Quantity of lithium that she returned = 250 milliliter.
Total stock would be now = 175 + 250 = 425 milliliter.
So, there was 425 milliliter of lithium before she used any of it.
Hence, 425 milliliter is the final answer.
