Answer:
this is violation of II law of thermodynamics
Explanation:
As per 2nd law of thermodynamics we know that heat always flows from high temperature to low temperature
If heat flows from low temperature to high temperature then it is only possible when some external work is done on the system
So here it says that initially two blocks are at 10 degree C and 20 degree C
Now the cool object will become cooler and hot object becomes hotter
which shows that heat is flowing from low temperature to high temperature
So this is violation of II law of thermodynamics
Answer:
Chargaff rule: The rule that in DNA there is always equality in quantity between the bases A and T and between the bases G and C. (A is adenine, T is thymine, G is guanine, and C is cytosine.) Named for the great Austrian-American biochemist Erwin Chargaff (1905-2002) at Columbia University who discovered this rule.
If you look below, we are using the centripetal acceleration formula. You just need to plug your numbers in and it should work!
Answer:
Number of electron on the fur will be 
Explanation:
We have given net charge on the fur 
Charge on one electron 
Let there are n number of electrons
So 


So number of electron on the fur will be
