Answer:
Explanation:
given,
charge of two spherical drop = 0.1 nC
potential at the surface = 300 V
two drops merge to form a single drop
potential at the surface of new drop = ?
r = 0.003 m
volume = 
= 
= 2.612 × 10⁻⁷ m³
![R =\sqrt[3]{\dfrac{2.612 \times 10^{-7}\times 3}{4\times \pi}}](https://tex.z-dn.net/?f=R%20%3D%5Csqrt%5B3%5D%7B%5Cdfrac%7B2.612%20%5Ctimes%2010%5E%7B-7%7D%5Ctimes%203%7D%7B4%5Ctimes%20%5Cpi%7D%7D)
R = 0.00396 m
Answer:
Argument in favor of less total energy consumption if the store is kept at a low temperature
Explanation:
Have in mind that if the store has numerous refrigerators and freezers, the energy consumption of those machines have to be included into the analysis.
Recall that the efficiency (or Coefficient Of Performance - COP) of a frezzer or refrigerator is inversely proportional to the temperature difference between the inside of th machine and the environment where it is operation, therefore the smaller the difference, the highest their efficiency. Therefore, the cooler the environment (the temperature at which the store is kept) the better performance of the running refrigerators and freezers.
Answer:
433 mph
Explanation:
We know that
...Eq(1)
Here,
Distance =1,592 miles
Time=3.68 hours
Putting the value of distance and Time in the Eq(1) We get
Velocity =
therefore Average velocity is 433 mph
W = Fd = 4(2100) = 8400 J
So the answer is A) 8400 J
I was just rewriting my notes on the work lesson I did in class today, so I saw this question at the perfect time!! :)
Hope it helps!! :)
Atomic Mass Unit is the answer
