Physics: A2.05-m-long rod, as measured in its rest frame, speeds by you longitudinally at 6.01 x 107 m/s. you measure its length as it passes. by how many millimeters do you determine the rod has contracted?

40 mm

Explanation:

L_o =Proper Length of rod = 2.05 m

Speed of rod = 6.01×10⁷ m/s

Length contraction

$L=\sqrt{1-\frac{v^2}{c^2}}L_o\\\Rightarrow L=\sqrt{1-\frac{(6.01\times 10^7)^2}{(3\times 10^8)^2}}\times 2.05=2.00844$

Final Length will be 2.01 m

So length that is contracted is 2.05-2.01 = 0.04 m

The length is contracted by 40 mm.

Carbohydrates attached to lipids and to proteins extend from the outward facing surface to the membrane. The second factor that leads to fluidity is the nature of the phospholipids themselves
