Answer: F= 10⁻¹¹ N
Explanation:
We are given that a molecular motor moves in steps of 100 Å.
The energy change for ATP hydrolysis is –60 kJ•mol⁻¹
Now we have to find the maximum resistive force against which motor can move cargo.
So the force will be equal to the energy value divided by the distance in meters.
F= = −6000000000
Ignoring the minus sign.
And for one molecule of ATP per step, the value is divided by Avogadro's number.
F=
F= 10⁻¹¹ N
Given:
altitude, x = 1 mile
speed, v = 560 mi/h
distance from the station, x = 4 mi
Solution:
To find the rate,
Now, from the right angle triangle in fig 1.
Applying pythagoras theorem:
differentiating the above eqn w.r.t 't' :
(1)
Now, putting values in eqn (1):
The rate at which distance from plane to station is increasing is:
