Answer:
The distance the water is traveling and the time it took.
Step-by-step explanation:
The speed formula is s= d/t so I would guess that is what the question means.
(Sorry if I didn't take a lot of time to answer, it had caps so I would guess that you needed the answer fast. )
Te difference of 2 standard deviation of a population n1 & n2 is given by the formula:
sigma (difference)=√(sigma1/n1 + sigma2/n2), Plug:
sigma(d)= √(49/100 + 36/50)
Sigma(d=difference) =1.1
B^-2/ab^-3 = b^-2/b^-3 x 1/a = b^[-2-(-3)] x 1/a = b x 1/a = b/a
Answer:
2.41
Step-by-step explanation:
Magnifcation = Image distance/object distance
Given;
Image distance = -53cm
Object distance = 22cm
Substitute
Magnification = 53/22
Magnification = 2.41
Note that the negative sign is not used in calculating magnification
