Base on my research, as of 2004 The U.S. devours about 20 million barrels of oil a day, according to the CIA. But base on Wikipedia, it says that a normal large tanker can only carry around 2 million barrels of oil. So to supply the U.S with this oil per day, it needs 10 normal large oil tankers.
Answer:
= 6 cm/s
Explanation:
<u><em>Given:</em></u>
Acceleration = a = 2 cm/s²
Time = t = 3s
Initial Velocity =
= 0 cm/s
<u><em>Required:</em></u>
Velocity =
= ?
<u><em>Formula:</em></u>
a = 
<u><em>Solution:</em></u>
2 = 
=>
= 2*3
=>
= 6 cm/s
Answer:
dependent variable
Explanation: Because sand changes when water touches it therefore it would be considered a dependent variable
Answer:
The speed of sound for middle C is 345.01 m/s.
Explanation:
Given that,
The frequency of middle C is 261.63 Hz
The wavelength of middle C note used when playing or singing music, 
We need to find the speed of sound for middle C. We know that the relation between speed, frequency and wavelength is given by the formula as follows :

So, the speed of sound for middle C is 345.01 m/s. Hence, this is the required solution.
