The length of daylight on the moon is about 29.5 days.</span>
From the earliest days, the Moon has been there in the Solar
System and there has never been a period when we couldn't gaze upward in the
night sky and either observe the Moon hanging there, or realize that it would
be back the precise one night from now (i.e. a New Moon). 
 A day on the Moon keeps going as long as 29.5 Earth days. We
can say that it would take 29.5 days for the Sun to move the distance over the
sky and come back to its unique position once more.
 
        
        
        
The electrical free path of electron is disturbed with vibrations not normal to normal / room temperature  because the electrical heater is agitating the conductor material. this causes the electrons to vibrate more creating more resistance to the flow.
        
             
        
        
        
Answer:
v = 75 m / 15 s = 5 m/s
Explanation:
Speed is equal to the distance traveled divided by the time.
v = d / t
 
        
             
        
        
        
The answer is; D
Cooking food kills bacteria. Putting it while still warm in the fridge gives a thermal shock to the remaining bacteria hence also acts towards positive food safety. Fridging food reduces reproduction rates of bacteria on the food hence their colonies cannot grow.  Allowing the food to cool before putting it in the fridge give time for bacteria colonies to settle on the food again.
