Answer:
230.4 s
Explanation:
The speed of car A is

and the distance travelled is

so the time taken for car A is

The speed of car B is

and the distance travelled is

so the time taken for car B is

So the difference in time is

Which corresponds to

so car B arrived 230.4 s before car A.
 
        
             
        
        
        
Let's cut through the weeds and the trash 
and get down to the real situation:
                  A stone is tossed straight up at  5.89 m/s .
                  Ignore air resistance.
Gravity slows down the speed of any rising object by  9.8 m/s every second.
So the stone (aka Billy-Bob-Joe) continues to rise for
                     (5.89 m/s / 9.8 m/s²)  =  0.6 seconds.
At that timer, he has run out of upward gas.  He is at the top 
of his rise, he stops rising, and begins to fall.
His average speed on the way up is  (1/2) (5.89 + 0) = 2.945 m/s .
Moving for 0.6 seconds at an average speed of  2.945 m/s, 
he topped out at
                    (2.945 m/s) (0.6 s) =  1.767 meters above the trampoline.
With no other forces other than gravity acting on him, it takes him
the same time to come down from the peak as it took to rise to it.
   (0.6 sec up) + (0.6 sec down)  =  1.2 seconds until he hits rubber again.

Answer : The frequency decreases by a factor of 2.
Explanation :
Given that the wave travels at a constant speed. The speed of the wave is given as :

Where
υ is the frequency of the wave 
and λ is the wavelength of the wave.
In this case, the speed is constant. So, the relation between the frequency and the wavelength is inverse.

If the wavelength increases by a factor of 2, its frequency will decrease by a factor of 2.
Hence, the correct option is (A) " The frequency decreases by a factor of 2 ".
 
        
                    
             
        
        
        
Hysical science is defined as the study of observable phenomena in the universe. 
<span>the main idea of physical science is known as the "scientific method". </span>
<span>this method states: </span>
<span>observe a "real" ( not imaginary ) phenomena. </span>
<span>make a hypothesis ( or theory / idea ) that EXPLAINS this phenomena. </span>
<span>conduct a real experiment to test this hyothesis. </span>
<span>confirm that the experiment validates the original hypothesis and if necessary amend the theory. </span>
<span>it has worked so well that the very communication you are having with me is a result of the wonders of physical science. </span>
