Mariulka [41]

Answer:

current (I)=V/R

current (I)=9.0/56022

so I=1.607×10 in the power of negative four Amperes (A)

12345 [234]

Answer:B) The binding site with a kid of7.9uM is the low affinity site.

Explanation:

The rate at which macro molecules like protein bind together is called affinity. The higher the affinity site the more readily these macro molecules fuses together. 7.9uM is a low affinity value than 359uM.

Two forces and are applied to an object whose mass is 9.31 kg. The larger force is . When both forces point due east, the object
kondor19780726 [428]

Answer:

the magnitudes of the two forces are 45.N and 1.5 N

Explanation:

This in a problem of composition of forces, as the forces are on a single axis, East-West, we can work as a problem of a single dimension, write Newton's second law for each case n

   • Two forces to the east

        F1 + F2 = m a1

  • One force to the east and the other to the west

        F1 - F2 = m a2

We see that we have a system of two equations with two unknowns, we proceed to solve it

We add sides equations

        F1 + F2 = m a1

        F1 - F2 = m a2

       2F1 = m (a1 + a2)

       F1 = m (a1 + a2) / 2

       F1 = 9.31 (0.626 +0.340) / 2

       F1 = 4.5 N

We substitute in one of the two equations and find the other force

       F1 + F2 = m a1

       F2 = m a1 - F1

       F2 = 9.31 0.646 - 4.5

       F2 = 1.5 N

     These are the magnitudes of the two forces 45.N and 1.5 N

A 1.10-kg particle moves in the xy plane with a velocity of v with arrow = (3.80 î − 4.10 ĵ) m/s. Determine the angular momentum
nirvana33 [79]

Answer:

15.961 kgm^2 / s along negative z axis

Explanation:

m = 1.10 kg,

v = (3.80 i - 4.10 j) m/s

r = (1.50 i + 2.20 j) m

The formula for the angular momentum is given by

\overrightarrow{L}=m (\overrightarrow{r}\times \overrightarrow{v})

\overrightarrow{L}=1.10 (1.50 i +2.20j)\times (3.80i-4.10j)

\overrightarrow{L}=-15.961 \hat{k}

Magnitude of angular momentum is 15.961 kgm^2 / s
