kumpel [21]

Answer: Sally

If Harry's negligent act injures Sally, and Susan, while attempting to come to Sally's aid breaks her arm in the process then, Harry is liable for the harm to Sally.

Explanation:

As a mathematical expression, we can say the action of Harry H, is directly proportional to the injury to Sally S; while the mistake of Susan N is directly proportional to injury to Sally S.

So, if H = S and N = S, it is safe to say

H = N = S.

Thus, Harry negligence create room for Susan mistake, which eventually harmed Sally.

Why do phospholipid from a biliary in water ?
Bond [772]

Phospholipids have a hydrophilic(water-liking) ‘head’ and a hydrophobic ‘tail’ so they are amphipathic. They form a lipid bilayer because of their amphipathic properties. The tails get sandwiches between the hydrophilic heads that are able to interact with water.

Hope this helps:)

What’s the change in thermal energy and particle arrangement of molten steel after becoming completely solid
Ann [662]

<u>Change in thermal energy and particle arrangement of molten steel after becoming completely solid:</u>

Due to the rise in the temperature, the particles start moving speedily. Because of the achieving the kinetic energy, which helps in the higher collision rate and makes the diffusion rate high. In case of the solids the particles are strongly bound in sequential order. Even though we can’t see it, but the vibrations can be felt. During heating the internal energy increases and helps the particle to move faster.

The human eye can detect up to 700 nanometers but the range adjacent to the visible spectrum is called the near infrared and the longer wavelength part is called far infrared. The region just below the visible in wavelength is called the near ultraviolet. Hence the visible part of electromagnetic spectrum lies in between ultraviolet and infrared.
