PLEASE HELP ME WITH THIS ONE QUESTION
adoni [48]

Answer:

B) R1 = 6 V and R2 = 6V

Explanation:

In series, both resistors will carry the same current.

that current will be I = V/R = 12 / (10 + 10) = 0.6 A

The voltage drop across each resistor is V = IR = 0.6(10) = 6 V

What is the wavelength of a radiowave that has a frequency of 9.650 x10^7 Hz (cycles per second)?h = 6.6261 x10^-34 J/sc = 2.998
slava [35]

Hello!!

For this, we only need frequency and speed, so for calculate we applicate formula:

\boxed{\lambda = V/f}

\textbf{Being:}

\sqrt{} \lambda = Wavelength = \   ?

\sqrt{} V = Velocity = 2.998*10^{8} \ m/s

\sqrt{} f = Frequency = 9,650*10^{7} \ Hz

\text{Then let's \textbf{replace it according} we information:}

\lambda = 2,998*10^{8} \ m /s  / 9,650*10^{7} \ Hz

\lambda  =  3.106 \ m

\textbf{Result:}\\\text{The wavelength of the radiowave is \textbf{3.106 meters}}

In a random sample of 200 students from Northern State University, 150 said that they own an Therefore, probably at least 50% of
kirza4 [7]

Answer:

No fallacy

Explanation:

The statement that at least  50% of the students at Northern State own an iPod is best categorized as no fallacy.

This statement is very true and consistent with the facts presented in the passage.

A fallacy is a mistaken belief usually based on biased arguments.

Total number of students sampled = 200

Number of iPod owners = 150

Percentage of iPod owners = \frac{number of iPod owners}{Number of sample} x 100

Percentage of iPod owners = \frac{150}{200} x 100 = 75%

We see that it is consistent to say that at least, 50% of the students in the sample are iPod owners.

Uniform solid sphere of mass M and radius R rotates with an angular speed w about an axis through is center A uniform solid cyli
Maru [420]

Answer:

e. 2ωs / √5

Explanation:

The rotational kinetic energy of any rigid body, like an extension of the translational kinetic energy, is defined as follows:

Krot = 1/2 *I * ω²

For a solid sphere of mass M and radius R, the moment of inertia regarding any axis through its center, is as follows:

I =2/5 M*R²⇒ Krot(sp) = 1/2 (2/5 M*R²)*ωs² (1)

For a solid cylinder, rotating through an axis running through the central axis of the cylinder, the moment of inertia can be calculated as follows:

I = 1/2 M*R² ⇒ Krot(c) = 1/2 (1/2*M*R²)*ωc² (2)

As both rotational kinetic energies must be equal each other, we can equate (1) and (2), as follows:

1/2 (2/5 M*R²)*ωs² = 1/2 (1/2*M*R²)*ωc²

Simplifying common terms, and solving for ωc, we have:

ωc = 2*ωs /√5
