A kinesin that is transporting a secretory vesicle uses approximately 80 ATP molecules/s. Each ATP provides a kinesin molecule w
1 answer:
Answer:
The force is
Explanation:
According to the inquiry, we understand that
The rate at which ATP molecules are utilized is
The energy yielded by a single ATP molecule is
The kinesin's velocity is
The power generated by the ATP in one second can be expressed mathematically as
After substituting the values
Now this power can be represented mathematically as
Where F indicates the force exerted by the kinesin
Therefore

Answer:
After a duration of 2.0 seconds, the angular momentum of the system is .
Explanation:
Let’s denote the forces acting on the rod as A, B, C, and D, and the distance between them as .
The torque produced by force A can be expressed as
,
for force B the torque is
,
the torque for force C is
,
and the torque due to force D is
.
This leads to a total torque on the stick as
Subsequently, this torque results in an angular acceleration in accordance with the formula
where represents the moment of inertia of the stick, which has a value of
.
Thus, the angular acceleration calculates to
.
Now, the angular momentum of the rod is given by
,
where is considered the angular velocity.
Given , we conclude that
Thus, , the angular momentum is
