Most of the currents identified have a circular shape. This is because as the air and water move between the equator to the pole

s, they are also affected by the Coriolis effect, which makes them follow a more circular path. Lesson 2.11 Question 10 options: True False

A person wants to make a metronome for music practice. He uses a 35-g object attached to a spring to serve as the time standard.

alukav5142 [94]

To develop this problem it will be necessary to apply the concepts related to the frequency of a spring mass system, for which it is necessary that its mathematical function is described as

$f = \frac{1}{2\pi} \sqrt{\frac{k}{m}}$

Here,

k = Spring constant

m = Mass

Our values are given as,

$m = 35g = 35*10^{-3}kg$

$f = 1 Hz$

Rearranging to find the spring constant we have that,

$k = (2\pi f \sqrt{m})^2$

$k = 4\pi^2 f^2 m$

$k = (4) (\pi)^2 (1) (35*10^{-3})$

$k = 1.38N/m$

Therefore the spring constant is 1.38N/m

Answer:

7.5 x 10⁻⁸N

Explanation:

Given parameters:

Mass 1 = 60kg

Mass 2 = 75kg

Distance between the bodies = 2m

Unknown:

Gravitational fore = ?

Solution:

The gravitational force between the two bodies can be derived using;

F = $\frac{G mass 1 x mass 2}{distance^{2} }$

G is the universal gravitation constant = 6.67 x 10⁻¹¹m³kg⁻¹s⁻²

Insert the parameters and solve;

F = $\frac{6.67 x 10^{-11} x 60 x 75}{2^{2} }$ = 7.5 x 10⁻⁸N

Briefly describe the difference between the CPC, COC, and CIC certifications. Can you work in a hospital or outpatient facility

madreJ [45]

Answer : the difference between the CPC, COC, and CIC Certified Professional Coder , Certified Outpatient Coder ,Certified Inpatient Coder

Explanation :

CPC - Certified Professional Coder is the gold standerd for medical coding in a physician.

COC - Certified Outpatient Coder is the only standalone outpatient coding credential in the healthcare .

CIC - Certified Inpatient Coder is the only standalone inpatient coding credential in the healthcare .

Yes, we can work in hospital and outpatient facility in COC.

If we have a professional certifications in coding then we can make a best physician.

Yes, credential is important because we can recognize that the doctor works in which field.

A baseball of radius r = 5.2 cm is at room temperature T = 20.8 C. The baseball has emissivity of ε = 0.86 and the Stefan-Boltzm

Marrrta [24]

Answer:

$P = 12.37 \frac{J}{s} = 12.37 Watts$

Explanation:

Previous concepts

The Thermal radiation is one of "3 mechanisms who allows to bodies exchange energy".

The thermal radiation formula is given by:

$\frac{P}{A} = \epsilon \sigma T^4$

Where $\sigma = 5.67 x10^{-8} \frac{J}{sm^2 K^4}$

If we solve for P we got:

$P = A \epsilon \sigma T^4$

Since we have a baseball ball considered as a sphere the superficial area is given by:

$A = 4\pi r^2$

Solution to the problem

And if we replace this into our equation of P we got:

$P = (4\pi r^2) \epsilon \sigma T^4$

And we can reorder this like that:

$P = 4 \epsilon \pi \sigma r^2 T^4$

We can convert the radius to meters and we got:

$r= 5.2 cm*\frac{1m}{100 cm}=0.052 m$

Now we can convert the temperature to Kelvin and we got:

$T = 20.8 +273.15 = 293.95 K$

$\epsilon = 0.86$ the emissivity given

And now we can replace into the formula for P and we got:

$P = 4*0.86*\pi *(5.67x10^{-8} \frac{J}{s m^2 K^4}) (0.052m)^2 (293.95 K)^4$

$P = 12.37 \frac{J}{s} = 12.37 Watts$
