A molecular motor moves along a microtubule track in steps of 100 Å displacements. The motor hydrolyzes one molecule of ATP per
1 answer:
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

The answer is 35.45 yds
Explanation:
You have to picture this to be able to understand it better (see attachment).
Start at the origin which is when the quarterback (QB) takes the ball. He runs backwards 12.1 yards, runs sideways for 19.8 yards (it doesn´t matter if he runs right or left), then he throws the ball forward 41.5 yards. If you look at the attachment, you can see I drew the path that the football followed. And then connected the dots from the origin and finish. The distance between those two points is the magnitude of the resultant displacement.
In order to calculate it, all you need to do is use the Pythagoream theorem, which says that the square of the hypotenuse equals the sum of the squares of the legs a and b of the triangle rectangle.
then solve for R
In this case, you know the length of leg a to be 19.8 yards which how much it moves sideways. And then, to get the length of leg b, all you need to do is substract how much it moved backwards from the 41.5yards forward displacement. This results in b leg being 29.4 yards long.
Now you have a triangle with:
- a = 19.8 yards
- b = 29.4 yards
Substituting this numbers in the equation:
- R = 35.45 yards
