Answer:
Displacement = 4000 m
Explanation:
Given that,
Each lap is 1000 m.
David completes 4 laps of his complex
We need to find David's displacement. In n laps, the net displacement is n time of distance covered.
Displacement = 4 × 1000
= 4000 m
Hence, Davis's displacement is 4000 m.
Answer:
By binding to enzymes' active sites, inhibitors reduce the compatibility of substrate and enzyme and this leads to the inhibition of Enzyme-Substrate complexes' formation, preventing the catalyzation of reactions and decreasing (at times to zero) the amount of product produced by a reaction.
Explanation:
Answer:
There are 5 valence electrons
Explanation:
Valence electrons are electrons found in the outermost shell of an atom.
a) 1.57 m/s
The sock spins once every 2.0 seconds, so its period is
T = 2.0 s
Therefore, the angular velocity of the sock is

The linear speed of the sock is given by

where
is the angular velocity
r = 0.50 m is the radius of the circular path of the sock
Substituting, we find:

B) Faster
In this case, the drum is twice as wide, so the new radius of the circular path of the sock is twice the previous one:

At the same time, the drum spins at the same frequency as before, therefore the angular frequency as not changed:

Therefore, the new linear speed would be:

And substituting,

So, we see that the linear speed has doubled.
