Answer:
90 N
Explanation:
The electrostatic force between two charges is given by:

where
k is the Coulomb's constant
q1, q2 are the two charges
r is the separation between the charges
In this problem we have
q1 = q2 = 0.005 C
r = 50 m
So the electrostatic force is

Answer:
Adding a reducing agent
Explanation:
Homodimeric proteins are formed by non-covalent interactions between two identical proteins (monomers).
Some of these intermolecular interactions are mediated by disulphide bonds which can be broken by a reducing agent like beta-mercaptoethanol (2-ME).
By adding the reducing agent to the gel, it is probable that the dimer is broken and the band observed will correspond to the two identical 22.5-kDa monomers.
A storm surge which is when the winds of the hurricane pull water levels up and cause floods inland
Answer:
35.7 m
Explanation:
Let


We have to find the distance between Joe's and Karl'e tent.


Substitute the values then we get




Because vertical component of B lie in IV quadrant and y-inIV quadrant is negative.
By triangle addition of vector






Hence, the distance between Joe's and Karl's tent=35.7 m
