Because they know physics :)
higher amplitude => higher potential energy => more to transform into kinetic energy => higher speed => higher range (distance)

17. What speed must you toss a ball straight up so it takes 4 s to return to you? Be sure to show all work to support your answe
Darya [45]

If we tossed up a coin with some velocity then its acceleration in the air is due to gravity which we can take as a = - 9.8 m/s^2

Also it is given that coin returns to initial position after 4 s

So after 4 s its displacement will become ZERO

now in this process we can say that in whole motion of the coin the net displacement of coin is zero and its acceleration is due to gravity remains constant.

We can use kinematics here

\Delta y = v_i t + \frac{1}{2} at^2

0 = v_i (4) - \frac{1}{2}(9.8)(4)^2

v_i = 19.6 m/s

so approximate speed of the coin must be nearly 20 m/s

Ionic bonds happen in an oxidation-reduction reaction true or false?
Nesterboy [21]

Answer: I think it is true.

Explanation: Oxidation occurs when electrons are lost, while reduction occurs when electrons are gained. The two processes are linked, whenever one substance is oxidized another has to be reduced. The sodium ions (Na+) and chloride ions (Cl-) combine to form solid sodium chloride, which is an ionic compound.

Earth is the only planet able to support _____. a. an atmosphere b. a cryosphere c. a lithosphere d. a biosphere
Nat2105 [25]

The correct answer to the question is D.Biosphere


Every planet has it's own gravity.Hence, they have their own atmosphere.The concentration of particles and gases may vary from planet to planet depending on their force of gravity.

Every planet contains the lithosphere,the hard and  rigid outer layer which contains the crust and mantle.  

Earth is the only habitable planet which supports biosphere.Its atmosphere contains 20% of oxygen along with nitrogen which are responsible for sustaining various types of flora and fauna as well as evolution of new species.
