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

Answer:
0.085 moles of N₂O₅ are needed
Explanation:
Given data:
Mass of NO₂ produces = 7.90 g
Moles of N₂O₅ needed = ?
Solution:
2N₂O₅ → 4NO₂ + O₂
Number of moles of NO₂ produced :
Number of moles = mass/ molar mass
Number of moles = 7.90 g/ 46 g/mol
Number of moles = 0.17 mol
now we will compare the moles of NO₂ with N₂O₅.
NO₂ : N₂O₅
4 : 2
0.17 : 2/4×0.17 = 0.085 mol
Thus, 0.085 moles of N₂O₅ are needed.
Answer:
La Nina
Explanation:
La Nina -
The word La Nina means " the little girl " , in spanish language .
La Nina , is an ocean - atmospheric process , which occurs in the eastern equatorial Pacific Ocean .
It is exactly opposite of El Nino , which means " the little boy " .
In the phase of La Nina , the temperature of the eastern equatorial Pacific Ocean becomes lower than the usual temperature by around 3°C to 5°C .
This phase of La Nina is for around 5 months in an year .
Hence , from the given statement of the question ,
The correct term is La Nina .
Answer:
<h2>The answer is 870 miles</h2>
Explanation:
The distance covered by an object given it's velocity and time taken can be found by using the formula
<h3>distance = velocity × time </h3>
From the question
velocity = 290 miles/hour
time = 3 hours
The distance between the two cities is
distance = 290 × 3
We have the final answer as
<h3>870 miles</h3>
