Comets orbit the sun just like planets do. Except a comet usually has a very elongated orbit. Thanks to the laws of gravity comets obey the same laws. A comets orbit takes it very close to the sun and then far away again.
Well, think about how the tides will be affected when the moon moves farther away. If the moon first started off very close the earth, we would have more tsunamis. (Scientists have found that the moon has possibly been closer to earth long ago.) While it moves away, soon there will no longer be many tides.

Find x
Since the triangle is a 45-45-90 triangle, the following relationship exists
--- i.e. the other legs are equal
So, we have:

Divide both sides by 2

Take square roots of both sides

Simplify

Answer:
At the dimer-dimer interface there might be acting non-covalent forces (van der waals, Hidrogene bridges, hydrophobic forces)
At the monomer-monomer interface there might be covalent forces acting (disulfide bridges).
Explanation:
On the SDS-PAGE application works by disrupting non-covalent bonds in the proteins, and so denaturing them. Therefore, the disulfide bridges won´t be disrupted, so the monomers will remain bounded.
Answer:
55.56 watt
Explanation:
Work (W) = 1000 J
time (T) = 18 sec
power (P) = ?
We know power is the rate of doing work so
p = w / t
= 1000 / 18
= 55. 56 watt
