Answer:
The change in volume is
Solution:
As per the question:
Coefficient of linear expansion of Copper,
Initial Temperature, T = = 273 K
Final Temperature, T' = = 273 + 100 = 373 K
Now,
Initial Volume of the block, V =
where
V' = Final volume
Note that:
The electric field lines begin from the higher voltage to the lower, because the negative pole is lower voltage than the positive pole.
Thus, The lines go out the positive charges and go in the negative charges.
Also,
Like poles repel, unlike poles attract
<u>Then The correct figure is (A)</u>
Answer:
Silicon-32
Explanation:
Silicon-32 is the isotope of silicon. It's half life is 153 years. It means that it takes 153 years to decay for half of a sample of Silicon atom which has 14 proton, 14 electron and 18 neutrons.
So, answer is Silicon-32.
Explanation:
yusef adds all of the values in his data set and then divide by the number of values in the set. the actual density of iron is 7.874 g/ml .
