Answer:

Base units are defined units based on specific objects or events in the physical world. Derived units are defined by combining base units.

Base units are defined by a particular process of measuring a base quantity whereas derived units are defined as algebraic combinations of base units. For example, length is a base quantity in both SI and the English system, but the meter is a base unit in the SI system only.

Answer:

Mass number is the sum of the protons and neutrons in the atomic nucleus.

The mass number (A) is the sum of the atomic number (Z), which is the number of protons, and the number of neutrons (N) in the atomic nucleus of an isotope of an element. A=Z+N

Answer: c is the correct answer

Explanation:

Option C is the correct answer.

Definition of Science: A way of discovering and knowing about the world.

Science

Science can be defined as the knowledge and understanding of the natural and social world following a systematic methodology based on evidence.

The scientific methodology includes objective observation, measurement and data evidence.

Science is a system of observations and experiments used to gain knowledge about how the universe works. Observations describe how and why things happen the way they do. Experiments are investigations used to explain how the world works.

Hence option C represents the best definition.

The solar system is very large with the boundaries located around the Orth cloud 100,000 Astronomical Units away

The correct option for, the distance to the nearest star if the solar system were the size of a campus is the option;

About a mile away

The reason the above selection is correct is as follows:

The ratio of the area of the solar system to the area of a campus = (π × (10⁵ × 149.6 × 10⁶)²)/(109.2651) = 6.4347487 × 10²⁴

Therefore, the linear scale factor ≈ √(6.4347487 × 10²⁴) ≈ 2.5366807 × 10¹²

Therefore, the corresponding distance to the distance of the nearest star to the solar system, X is given as follows;

X = (40,208,000,000,000 km)/(2.5366807 × 10¹²) ≈ 15.85 km ≈ 9.85 miles

Given that compared with the largest campus the distance is at most approximately 9.85 mile, if the solar system is taken to be a much smaller campus, the distance of the closest star Proxima Centauri will be about a mile away

The average speed of the ant is 0.276 cm/s and the average velocity is 0.136 cm/s.

The correct answer is option D.

In the given graph, we can deduce the following;

The average speed of the ant is calculated as;

[tex]average \ speed = \frac{total \ distance }{total \ time }[/tex]

The total distance from the graph is calculated as follows;

The total distance = (6 + 2 + 2 + 7 + 7 + 3 + 2) cm = 29 cm

[tex]average \ speed = \frac{total \ distance }{total \ time } = \frac{29 \ cm}{105 \ s} = 0.276 \ cm/s[/tex]

The average velocity is calculated as the change in displacement per change in time.

The displacement is the shortest distance between the start and end positions.

Notice, you have a right triangle, now calculate the length of  line P.

                                                ↓end

                                                ↓

                                                ↓

  start -------------13 cm------------

Use Pythagoras theorem to solve for P.

[tex]P^2 = 6^2 + 13^2\\\\P^2 = 36 + 169\\\\P^2 = 205\\\\P= \sqrt{205} \\\\P = 14.318 \ cm[/tex]

The average velocity of the ant is calculated as;

[tex]average \ velocity= \frac{\Delta displacemnt }{total\ time }= \frac{14.318 \ cm}{105 \ s} = 0.136 \ cm/s \\\\[/tex]

Thus, the average speed of the ant is 0.276 cm/s and the average velocity is 0.136 cm/s.

One must drive [tex]$41 \cdot 8\,miles$[/tex] north and [tex]$68 \cdot 24\,miles$[/tex] south, in order to travel from Atlanta to Macon.

Explanation:

• The distance of an object can be defined as the complete path travelled by an object.

• To find the distance, find its north component.

• For reference see the below graph:

[tex]$$\[\begin{align}& D_{south} = 80\sin \left( {58 \cdot {5^ \circ }} \right) \\& D_{north} = 80\cos \left( {58 \cdot {5^ \circ }} \right) \\\end{align}\]$$Since, $\sin \left( {58 \cdot {5^ \circ }} \right) = \cdot 853$ and $\cos \left( {58 \cdot {5^ \circ }} \right) = \cdot 5224$: therefore,$$\[\begin{align} D_{south} &= 80 \times \left( { \cdot {{853}^ \circ }} \right) \\ \Rightarrow {D_{south}} &= 68 \cdot 24\,miles \\ \end{align}\]$$[/tex]

And

[tex]$$\[\begin{align} D_{north}& = 80 \times \cdot 5224 \\ \Rightarrow D_{north}& = 41 \cdot 8\,miles \\ \end{align}\]$$[/tex]

• Hence, one must drive [tex]$41 \cdot 8\,miles$[/tex] north and [tex]$68 \cdot 24\,miles$[/tex] south, in order to travel from Atlanta to Macon.

Answer:

a) Object X is positively charged

Explanation:

Unlike charges attract each other

Like charges repel each other

The object X will be positively charged through charging by conduction.

The given parameters:

A charge can be produced by conduction. This method of charge generation involves charging a neutral body by placing it in contact charged body.

When object X is placed in contact with object Y, which is negatively charged, the negative charges of object Y repels negative charges of object X. This leaves object X with excess protons, thereby becoming positively charged.

Thus, the object X will be positively charged through charging by conduction.

0.5 = sin(0.5πf)

take arcsine of both sides in radians

0.52359 = 0.5πf

f = 0.52359 / 0.5π = 0.33333...

The frequency of the oscillator is 0.33 Hz.

We have an equation of SHM.

We have to identify the frequency of the oscillator.

The conditions are -

According to the question, we have -

x = 0.5 sin(2πft)

Substituting the values -

0.25 = 0.5 sin(2πft)

sin(2πft) = 0.5

sin(2πft) = 1/2

sin(2πft) = sin(π/6)

2πft = π/6

2ft = 1/6

f = [tex]\frac{1}{12t}[/tex] = [tex]\frac{1}{12\times 0.25}[/tex] = 0.33 Hz

f = 0.33 Hz

Hence, the frequency of the oscillator is 0.33 Hz

The heating element of an electric oven is designed to produce 3.9 kW of heat when connected to a 240-V source. Then the resistance of the element is 14.7Ω

When A 120-V hair dryer has two settings: 950 W and 1400 W then the resistance at 950 W is 15.15Ω and at 1400 W is 10.28Ω.

The pace at which electrical energy is transmitted by an electric circuit is referred to as its power. The watt is the SI unit of power, equal to one joule per second. Watts, like other SI units, have standard prefixes: thousands, millions, and billions of watts are referred to as kilowatts, megawatts, and gigawatts, respectively.

It is a popular misperception that electric power is purchased and sold, whereas electrical energy is. Electricity, for example, is sold to users in kilowatt-hours (kilowatts multiplied by hours), because energy is defined as power multiplied by time.

In this problem,

Given,

Power P = 3.9 KW

Voltage V = 240 V

P = V²/R

3.9 × 10³ = 240²/R

R = 240²/3.9 × 10³

R = 14.7Ω

For hair dryer,

given,

P = 950 W or 1400 W

V = 120 V

P = V²/R

950 = 120²/R

R = 120²/950

R = 15.15Ω

P = V²/R

1400= 120²/R

R = 120²/1400

R = 10.28Ω
