What speed would a fly with the mass of 0.55 g need in order to have the same kinetic energy as the automobile in the term 19
larisa86 [58]

<u>The question does not provide enough information to complete the answer, so I'll assume the needed data to help you to solve your own problem</u>

Answer:

<em>The fly should need to move at 9,534.6 m/s to have the same kinetic energy as the automobile</em>

Explanation:

<u>Kinetic Energy </u>

Is the capacity of a body to do work due to its speed and is computed by

\displaystyle K=\frac{mv^2}{2}

We are not given enough data to compare the kinetic energy of the fly with that of the automobile. We'll assume the following characteristics:  

m_a=500\ kg

v_a=10\ m/s

So its kinetic energy is

\displaystyle K_a=\frac{(500)10^2}{2}

\displaystyle K_a=25,000\ J

The mass of the fly is  

m_f=0.55\ gr=0.00055\ kg

To have the same kinetic as the automobile:

\displaystyle \frac{m_fv_f^2}{2}=25,000

Solving for v_f

\displaystyle v_f=\sqrt{\frac{2(25,000))}{m_f}}

\displaystyle v_f=\sqrt{\frac{50,000}{0.00055}}

v_f=9,534.6\ m/s

The fly should need to move at 9,534.6 m/s to have the same kinetic energy as the automobile

_________ are exchanged or shared during the formation of a chemical bond.
Thepotemich [5.8K]
<span>A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds; or through the sharing of electrons as in covalent bonds.

How do fossils provide evidence of continental drift?
Alex777 [14]
C explanation: There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined. If Continental Drift had not occurred, the alternative explanations would be: They swam to the other continent/s in breeding pairs to establish a second population. ...

It is said that a gas fills all the space available to it. Why then doesn't the atmosphere go off into space?
Alex777 [14]
Earth has its own atmosphere. That is one reason all the water that has been on Earth has been recycled through the water cycle. It never leaves Earth’s atmosphere.
