omeli [17]

Answer:

<h3>The answer is 2 s</h3>

Explanation:

The time of flight can be found by using the formula

$t = \frac{d}{v} \\$

d is the distance covered

v is the velocity

From the question we have

$t = \frac{100}{50} = \frac{10}{5} \\$

We have the final answer as

You do a certain amount of work on an object initially at rest, and all the work goes into increasing the object’s speed. If you

EleoNora [17]

Answer:

$\sqrt{2}v$

Explanation:

The work done on the object at rest is all converted into kinetic energy, so we can write

$W=\frac{1}{2}mv^2$

Or, re-arranging for v,

$v=\sqrt{\frac{2W}{m}}$

where

v is the final speed of the object

W is the work done

m is the object's mass

If the work done on the object is doubled, we have W' = 2W. Substituting into the previous formula, we can find the new final speed of the object:

$v'=\sqrt{\frac{2W'}{m}}=\sqrt{\frac{2(2W)}{m}}=\sqrt{2}\sqrt{\frac{2W}{m}}=\sqrt{2}v$

So, the new speed of the object is $\sqrt{2}v$ .

How strong does an earthquake have to be to cause a tsunami

Vesnalui [34]

Answer:

An earthquake with the magnitude of more than 7.5 on the Richter scale can cause to a destructive Tsunami.

Explanation:

According to International Tsunami Information center, the cause of the most destructive tsunami is shallow and large earthquake with the epicenter or fault line on the ocean floor or near the ocean floor.
When the tectonic plates (are pieces of earth's crust and uppermost mantle) are collided with each other then the earthquake occurs. This results in the displacement of large area of ocean floor from few km to 1000 km or more. This displacement of ocean floor in the formation of tsunami waves.
Like in the 1960, the tsunami in Chile was resulted due to earthquake with the magnitude of 9.5 on Richter scale with rupture area of over 1000 km. This tsunami not only cause destruction in Chile but also affected the other countries like Japan.
