Explanation:

ohm found that current, voltage, and resistance in a circuit are always related in the same day.

ohms obersivations

ohms found that if the factors that affect resistance are held constant, the resistance of most conductors does not depend on the voltage across them charging the voltage in a circuit changes the current but does not change the resistance regardless of the applied voltage. the ohms law resistance in a circuit is equal to voltage divided by current

(Unit = Hz)
please help me guys will give brainliest and lots of points

Answers

Answer: The 180-Hz sinusoid is called the third harmonic, since its frequency is three times that of the fundamental frequency.

Explanation: Harmonics are integer multiples of the fundamental frequency. For example, if the fundamental frequency is 50 Hz (also known as the first harmonic) then the second harmonic will be 100 Hz (50 * 2 = 100 Hz), the third harmonic will be 150 Hz (50 * 3 = 150 Hz), and so on.

A mustang, has an average velocity of 33 m/s while covering a course that is 21 miles long. (1 mile = 1609 m). How long did it take the driver to complete the course?

Answers

Answer:

t = 1023.9 seconds

Explanation:

Given that,

The average velocity of a Mustang, v = 33m/s

Distance, d = 21 miles = 33789 m

Let the driver takes t seconds. So,

Speed = distance/time

[tex]t=\dfrac{d}{v}\\\\t=\dfrac{33789}{33}\\\\t=1023.9\ s[/tex]

So, it will take 1023.9 seconds to complete the course.

The speed of light in air is 3.00 x 10^8 m/s. If a light wave has a wavelength of 5.80 x 10^-7m, what is its frequency?

Answers

Answer:

5.17 x 10^14 1/s

Explanation:

Equation:

c = λ f

c = speed of light

λ = wavelength

f = frequency

Solve:

3.00 x 10^8 m/s = (5.80 x 10^-7m) * f

f = (3.00 x 10^8 m/s) / (5.80 x 10^-7m)

f = 5.17 x 10^14 1/s

Which of Mendel principles would apply to mating two organisms that have two different alleles for three different traits

Answers

Answer:

Law of independent assortment

Explanation:

This is because law of independent assortment state that alleles of two or more genes when two organisms mate will be inherited or pass down to gametes which are in one way or the other independent of each other or each of the alleles. Therefore parent can have up to three different traits and the alleles can be inherited by the gametes.

What are the properties of scientists?

The properties of scientists are as follows:

They must be curious about their work.They must have a lot of patience as they are required to repeat experiments multiple times. Their courageous behavior motivates them to perform consistently.They are open-minded and free from any type of cultural and religious bias. They are creative, persistent, communicative, and detail-orientated individuals.

If scientists have properties of bias and discrimination, they never work consistently and are focused because their biased behavior ruins their interest, talent, and future perspectives.

Therefore, when conducting an experiment, a scientist should exhibit all of these traits except bias. Thus, the correct option for this question is A.

a person walks 750m due north then 250 m due east of the entire walk takes 12 min find the person average velocity​

Answers

Answer:

v = 1.098 m/s

Explanation:

Given that,

A person walks 750m due north then 250 m due east of the entire walk takes 12 min.

We need to find the average velocity of the person.

Displacement,

[tex]d=\sqrt{750^2+250^2} \\\\d=790.56\ m[/tex]

Average velocity = displacement/time

[tex]v=\dfrac{790.56\ m}{12\times 60\ s}\\\\v=1.098\ m/s[/tex]

So, the average velocity of the person is 1.098 m/s.

While at the county fair, you decide to ride the Ferris wheel. Having eaten too many candy apples and elephant ears, you find the motion somewhat unpleasant. To take your mind off your stomach, you wonder about the motion of the ride. You estimate the radius of the big wheel to be 15 m, and you use your watch to find that each loop around takes 23 s.A. What is your speed?
B. What is the magnitude of your acceleration?
C. What is the ratio of your weight at the top of the ride to yourweight while standing on the ground?
D. What is the ratio of your weight at the bottom of the ride toyour weight while standing on the ground?

Answers

Answer:

Explanation:

From the given information:

radius = 15 m

Time T = 23 s

a) Speed (v) = [tex]\dfrac{2 \pi r}{T}[/tex]

[tex]v = \dfrac{2\times \pi \times 15}{23}[/tex]

v = 4.10 m/s

b) The magnitude of the acceleration is:

[tex]a = \dfrac{v^2}{r} \\ \\ a = \dfrac{(4.10)^2}{15}[/tex]

a = 1.12 m/s²

c) True weight = mg

Apparent weight = normal force

From the top;

the normal force = upward direction,

weight is downward as well as the acceleration.

true weight - normal force = ma  

apparent weight =mg - ma  

[tex]\dfrac{apparent \ weight}{true \ weight} = \dfrac{(mg - ma)}{(mg)}[/tex]

[tex]=1- \dfrac{1.12}{9.8}[/tex]

= 0.886 m/s²

d)

From the bottom;

acceleration is upward, so:

apparent weight - true weight = ma

apparent weight = true weight + ma

[tex]\dfrac{apparent \ weight }{true \ weight} =\dfrac{ mg + ma}{mg}[/tex]

[tex]\dfrac{apparent \ weight }{true \ weight} =1+ \dfrac{a}{g} \\ \\ = 1 + \dfrac{1.12}{9.8}[/tex]

[tex]= 1 + \dfrac{1.12}{9.8} \\ \\[/tex]

= 1.114 m/s²
