Answer:
A. The speed of the wave increases four times.
An approximation used to measure building height is 10 feet per building level.
Converting from feet to meters using the equation:
1 ft = 0.3048m
10 ft = 3.048m
Multiplying that by 30 storeys, we get:
3 x 3.048m = 91.44m, which is near the answer of (3) 10^2 m or 100m.
The Results For Earth's Circumcised were quite accurate. the diameter of earth is 12,740 km, the length of the stadium would be 1,140 km.
Answer:
= 30N - 10N = 20N
