Examples of Selectively Permeable Membranes. Selectively permeable membranes can be found around a variety of cells and places. The most common example is the phospholipid bilayer cell membrane that surrounds every cell in our bodies. Another example of a selectively permeable membrane is the inner membranes of an egg.Nov 5, 2014
Answer:
An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.
<span>Energy transferred to a machine equals energy transferred from it. It is because according to conservation of energy we can't create or destroy energy so, energy remains constant however, their form can be change by machine's
In short, Your Answer would be Option C
Hope this helps!</span>
Answer:
A) 
B) 
Explanation:
Given:
mass of car, 
A)
frequency of spring oscillation, 
We knkow the formula for spring oscillation frequency:
Now as we know that the springs are in parallel and their stiffness constant gets added up in parallel.
<u>So, the stiffness of each spring is (as they are identical):</u>
B)
given that 4 passengers of mass 70 kg each are in the car, then the oscillation frequency:
