Human building a drainage system could affect the water cycle because :
C. water would be directed to a new location because of the drains
This could potentially changed the natural occurrence that usually happened within the water cycle
hope this helps
Answer:
Because from the atomic number of an element we can predict some of its properties; the properties of elements are a periodic function of their atomic numbers. That is the periodic law which is basically used to synthesize new and understand existing and undiscovered elements

Answer:
1) Measuring cylinder
2) Top Pan Balance
Explanation:
To find the density of the pebble Nabil should first accurately measure the mass of the pebble using the top pan balance
He should then fill the displacement can till the water reaches the outlet pipe at the to of the cylinder
He should then place the pebble into the cylinder carefully ans allow the water that would start coming out to stop
The volume of water in the displaced cylinder is then measured and the density is found by dividing the mass of the pebble by the volume of water in the measuring cylinder

Explanation:
Given that,
The initial velocity of an arrow is 23.4 m/s
We need to find the time taken by it to reach its maximum height. Let the maximum height is h.
Using third equation of motion to find height first.
At maximum height, v = 0
a = -g
Let t is the time to reach its maximum height. So, it can be calculated using second equation motion as follows :
Hence, it will take 2.35 seconds to reach its maximum height.
