Answer:
x=24
Step-by-step explanation:
Here, you need to make proportion and find x.
12:16=18:x
We multiply 12 by x and 16 by 18:
12x=288
Divide by 12 both sides :
x=24
The weight (or mass) is irrelevant.
The period t = sqrt(2*pi*sqrt(l/g) where g is the acceleration due to gravity.
so t = 2*pi*sqrt(5/9.8) = 4.49 seconds.
Frequency = 1/period = 0.223 Hertz.
Answer:
D
Step-by-step explanation:
The median is the middle value in the data distribution.
From 1 → 4 there are14 values ( count the blocks )
From 5 → 10 there are 14 values
Thus the middle value of the distribution is 5, that is
median is 5 → D
