Answer:
Shape of the object
Explanation:
This depends on the shape of the object. For a spherical object, a unitless value of 0.47 is typical. The magnitude of the velocity squared. The faster you go, the greater the air resistance force
1 The question asks for a certain quantity of examples in a list (Name 6 factors that contributed to the start of World War I, What 3 subatomic particles constitute an atom? etc).
2 The question is academically precise and, therefore, indecisive in the wording (What are the 2 kinds of loading most professional engineers and academics in the field of engineering today generally consider to be relevant in most cases when considering typical types of structure usually made of common materials using well-understand methods?)
3 The question challenges the answerer to defend a position as opposed to merely rattling off a list based on knowledge alone, thereby invoking higher levels of Bloom's Taxonomy. (What are 4 arguments that could be used to defend arguments made by the physicists of the day that electromagnetic waves must move through an illusive substance called 'the ether?)
The maximum speed of the donkey is 10.72m/s
The question is based on the principle of motion in one dimension and hence formulas of motion in one dimension can be applied.
It is given that donkey attains an acceleration of 1.6 m/s^2
The time taken to accelerate to given speed is 6.7 seconds
We use the formula v=u + at to find the fastest speed
v is the final or maximum speed
u is the initial speed which in this case is 0 as the donkey is at rest
a is the acceleration of the donkey
t is the time taken in seconds
v = u + at
v= 0 + 1.6 x 6.7
= 10.72 m/s
Hence the donkey obtains the speed of 10.72 m/s

Answer:
Any choices for the blank?
Answer:
Wheel A.
Explanation:
The lesser the moment of inertia, the greater the angular acceleration. Then, the moments of inertia of each wheel are described below:
Wheel A
![I_{A} = M\cdot R^{2}](https://tex.z-dn.net/?f=I_%7BA%7D%20%3D%20M%5Ccdot%20R%5E%7B2%7D)
Wheel B
![I_{B} = \frac{1}{2}\cdot M \cdot (2\cdot R)^{2}](https://tex.z-dn.net/?f=I_%7BB%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%5Ccdot%20M%20%5Ccdot%20%282%5Ccdot%20R%29%5E%7B2%7D)
![I_{B} = 2\cdot M\cdot R^{2}](https://tex.z-dn.net/?f=I_%7BB%7D%20%3D%202%5Ccdot%20M%5Ccdot%20R%5E%7B2%7D)
The wheel A accelerates faster in response to the torque.
