Answer:
Object 2 has the larger drag coefficient
Explanation:
The drag force, D, is given by the equation:
Object 1 has twice the diameter of object 2.
If
Area of object 2,
Area of object 1:
Since all other parameters are still the same except the drag coefficient:
For object 1:
For object 2:
Since the drag force for the two objects are the same:
Obviously from the equation above, c₂ is larger than c₁, this means that object 2 has the larger drag coefficient
Answer:
<h3>The answer is option B</h3>Explanation:
The frequency of a wave can be found by using the formula
where
c is the velocity
From the question
wavelength = 0.39 m
c = 86 m/s
We have
We have the final answer as
<h3>200 Hz</h3>Hope this helps you
Answer:
<h3>The answer is 2 m/s²</h3>Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
where
f is the force
m is the mass
From the question
f = 20 N
m = 10 kg
We have
We have the final answer as
<h3>2 m/s²</h3>Hope this helps you
