Answer: The whole journey is 3,250km.
Step-by-step explanation:
20% = 650km
20 * 5 = 100%
650 * 5 = 3,250km
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:
y=1
Step-by-step explanation:
1. Isolate the variable
1+2y=3
-1 -1
2y=2
__ _
2 2
y=1
