Answer:
48cm by the minus of difference of 32 CM length 20 CM because of the length of the building
Answer:
Explanation:
average velocity is 41.6/1.89 = 22.0 m/s
initial velocity u is
22.0 = (u + u - 9.81(1.89))/2
44.0 = 2u - 18.5
62.56 = 2u
u = 31.3 m/s
max height is
v² = u² + 2as
s = (v² - u²) / 2a
s = (0² - 31.3²) / (2(-9.81)) = 49.9 m
49.9 = 41.6 = 8.27 m higher

Answer:
6
Explanation:
The function which is inverse to exponentiation is called logarithm.
It is of the form

The 10 here is the base of the logarithm. The logarithm with base 10 is called common logarithm

So, log(1,000,000) = 6
