Answer:

Correct answer is

Pseudoscience is often based only on opinions.
Pseudoscience often involves explanations of beliefs.
Pseudoscience includes subjective ideas.

Explanation:

pseudoscience is a combination of two words pseudo(spurious or not genuine) and science. As the name pseudoscience indicate that its not genuine science or its fake science. pseudoscience is based on practices or opinions which are believed to be based on scientific method but actually these practices are not based on scientific method and these opinions or ideas cannot be proved by a scientific method.Pseudoscience often involves explanations of beliefs. Pseudoscience includes subjective ideas therefore it never changes.

for example astrology is pseudoscience because it is not based on scientific method but astronomy is a science because it is based on scientific method.

If the volume of an object is reported as 5.0 ft3 what is the volume in cubic meters

12345 [234]

The problem statement is simply asking us to convert units. We convert from units of ft^3 to units of m^3. To do this, we need a conversion factor. For this case, we use 1 m is equal to 3.28084 ft. We do as follows:

5.0 ft^3 ( 1 m / 3.28084 ft )^3 = 0.1416 m^3

Answer:

F = 0.535 N

Explanation:

Let's use the concepts of energy, at the highest and lowest point of the trajectory

Higher

Em₀ = U = mg y

Lower

$Em_{f}$ = K = ½ m v²

Emo = $Em_{f}$

mg y = ½ m v2

v = √ 2gy

y = L - L cos θ

v = √ (2g L (1-cos θ))

Now let's use Newton's second law n at the lowest point where the acceleration is centripetal

F = ma

a = v² / r

In turning radius is the cable length r = L

F = m 2g (1-cos θ)

Let's calculate

F = 2 1.25 9.8 (1 - cos 12)

F = 0.535 N

An 80.0-kg object is falling and experiences a drag force due to air resistance. The magnitude of this drag force depends on its

FromTheMoon [43]

Answer:

The terminal speed of this object is 12.6 m/s

Explanation:

It is given that,

Mass of the object, m = 80 kg

The magnitude of drag force is,

$F_{drag}=12v+4v^2$

The terminal speed of an object is attained when the gravitational force is balanced by the gravitational force.

$F_{drag}=mg$

$12v+4v^2=80\times 9.8$

$4v^2+12v=784$

On solving the above quadratic equation, we get two values of v as :

v = 12.58 m/s

v = -15.58 m/s (not possible)

So, the terminal speed of this object is 12.6 m/s. Hence, this is the required solution.
