The grand canyon is 884 m deep
<h3>Formula for velocity of echo</h3>
The velocity of an echo can be obtained by using the following formula
v = 2x / t
Where
- v is the velocity
- x is the distance
- t is the time
With the above formula, we can determine how depth the grand canyon. Details below:
<h3>How to determine the depth of the grand canyaon</h3>
- Velocity (v) = 340 m/s
- Time (t) = 5.2 s
- Depth (x) =?
v = 2x / t
340 = 2x / 5.2
Cross multiply
2x = 340 × 5.2
2x = 1768
Divide both sides by 2
x = 1768 / 2
x = 884 m
Thus, the grand canyon is 884 m deep

In 2 hours, it went 60 metres. 60 / 2 = 30 so true
Answer:
There is a couple different ways to determine if a bond is ionic or covalent. By definition, an ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals. So you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals.
