The unit represents a value that is one order of magnitude larger than a decimeter is a meter

<h3>Further explanation </h3>

Magnitude is something that can be measured or counted

The principal amount is the amount that has been determined based on the agreement of the scientists

Derivative magnitude is a quantity derived from the principal amount

There are 7 main quantities that have been determined based on international standards, namely:

1. Length, meters (m)
2. Time, second (s)
3. Mass, kilograms (kg)
4. Temperature, kelvin (K)
5. Light intensity, candela (cd)
6. Electric current, amperage (A)
7. Amount of substance, mol (m)

The length of the principal is to indicate the distance between two points in a place

The symbol is usually expressed in l, length

Length measurements can be used by several measuring instruments such as ruler, caliper length, meter, screw micrometer

The main length unit consists of 7 units other than other units of length such as inches, miles, yards, feet:

Kilometers, km
Hectometer, hm
Dekameter, dam
Meters, m
Decimeter, dm
centimeters, cm
millimeters, mm

Each one unit descends then multiplied by 10, and if one unit increases then divided by 10

Conversion of other mass units:

mm millimeters = 10⁻³ m

km kilometers = 10³ m

µm micrometers (mcm) = 10µm

nm nanometers = 10⁻⁹ m

Gm gigameters = 10⁹ m

ρm picometers = 10⁻¹² m

An order of magnitude used base ten number.

If numbers differ by one order of magnitude, so the number is about 10 times different in quantity . If values differ by two orders of magnitude, they differ about 100.

The decimeter unit is located between the centimeter and meter.

Decimeter value = 10⁻¹m, centimeter = 10⁻² m, so that the unit represents a value that is one order of magnitude larger than a decimeter is meter

<u>The unit that represents the value of one order higher than the decimetre is </u><u>meter. </u>

Further Explanation:

The units are the ways of representation of the physical quantities and the amount of magnitude contained by the particular physical quantity.

For example: the length is a measure of the distance between the two points. The standard quantity to measure the length is metre. There are several other magnitudes that can measure the smaller and larger order of magnitudes.

The different magnitudes that are used to measure lengths of different order are:

• Kilometre $\left( {{{10}^3}\,{\text{m}}} \right)$

• Hectometre $\left( {{{10}^2}\,{\text{m}}} \right)$

• Decametre $\left( {{{10}^1}\,{\text{m}}} \right)$

• Metre $\left( {1\,{\text{m}}} \right)$

• Decimetre $\left( {{{10}^{ - 1}}\,{\text{m}}} \right)$

• Centimetre $\left( {{{10}^{ - 2}}\,{\text{m}}} \right)$

• Millimetre $\left( {{{10}^{ - 3}}\,{\text{m}}} \right)$

<u>Thus, the quantity that has the magnitude of one order larger than the decimetre is </u><u>metre. </u>

svlad2 [7]

Answer:

Acceleration → Change in velocity divided by time.

Proportional → Net force and acceleration

Inversely Proportional → Mass and acceleration

Net force Not Equal to zero → Driving a car up the on-ramp of the freeway

Net force Equal to zero → Driving a car with cruise control on, straight down.

Acceleration → Net force divided by mass

Force → Mass times acceleration.

Explanation:

Below we will explain each choice.

A) Acceleration by means of the following expression of kinematics is defined as the change of velocities in a given time.

$a=\frac{v_{f}-v_{o}}{t}$

where:

a = acceleration [m/s²]

Vf = final velocity [m/s]

Vo = initial velocity [m/s]

t = time [s]

Newton's Second Law tells us that the sum of forces in a body is equal to the product of mass by acceleration so we have the following expression.

F = m*a

where:

F = force [N] (units of Newtons)

m = mass [kg]

a = acceleration [m/s²]

As we can see in the previous equation The Force is proportional to the acceleration, that is to say, every time the acceleration increases or decreases this same will happen with the force, increases or decreases.

In Newton's second law we see an inversely proportional relationship, which is best seen if we clear the term of acceleration.

$a=\frac{F}{m}$

In any mathematical expression where a term is in the denominator, we can say that this is inversely proportional to the term to the left of the equal sign.

When a vehicle climbs a hill or climbs a slope, forces such as the weight of the vehicle act in the opposite direction to the movement, so the sum of the forces cannot be equal to zero.

When a vehicle moves on a track at a constant speed that is to say at cruising speed, we say that its acceleration is zero, therefore the sum of the forces acting on the moving vehicle is equal to zero.

Acceleration is defined as the relationship between Force and mass

$a =\frac{F}{m}$

Force is defined as the product of mass by acceleration.

F = m*a

1) A car accelerates uniformly from rest and reaches a speed of 19.8 m/s in 7 s. The diameter of a tire is 38.5 cm. Find the num

andre [41]

Answer:

1) 57 revolutions.

2) 4.52 m

3) 1531.2 m

Explanation:

Question 1:

Given:

Initial velocity, $u = 0$

Final velocity, $v = 19.8\ m/s$

Time, $t = 7\ s$

Acceleration, $a = \frac{\textrm{Final velocity-Initial velocity}}{Time}=\frac{19.8}{7}=2.83\ m/s^2$

Now, displacement of the tire is given as:

$S=ut+\frac{a}{2}t^2\\S=0+\frac{2.83}{2}7^2=69.335\ m$

Displacement of tire in 1 revolution is equal to its circumference.

Therefore, displacement in 1 revolution = $\pi\times(Diameter)=\pi \times 38.5\times 10^{-2}=1.2095\ m$

Now, number of revolutions is given as:

$N=\frac{Total\ displacement}{Displacement\ per\ revolution}\\N=\frac{69.335}{1.2095}=57$

Therefore, the number of revolutions are 57.

Question 2:

Given:

Radius of the wheel is, $R=4.8\ m$

Angle of rotation is, $\theta=54$ °

Converting degree to radians, we get:

$\theta=54\times \frac{\pi}{180}=0.3\pi$

Now, path length is given as:

$L=R\theta=(4.8)(0.3\pi)=1531.2\ m$

Therefore, the path length of a point on the wheel is 4.52 m

Question 3:

Radius of the wheel is, $R=4.8\ m$

Angle of rotation is, $\theta=319$ radians

Now, path length is given as:

$L=R\theta=(4.8)(319)=4.52\ m$

Therefore, the path length of a point on the wheel is 1531.2 m.

Exercise 2.4.6: Suppose you wish to measure the friction a mass of 0.1 kg experiences as it slides along a floor (you wish to fi

JulijaS [17]

Answer:

b = 0.6487 kg / s

Explanation:

In an oscillatory motion, friction is proportional to speed,

fr = - b v

where b is the coefficient of friction

when solving the equation the angular velocity has the form

w² = k / m - (b / 2m)²

In this exercise we are given the angular velocity w = 1Hz, the mass of the body m = 0.1 kg, and the spring constant k = 5 N / m. Therefore we can disperse the coefficient of friction

let's call

w₀² = k / m

w² = w₀² - b² / 4m²

b² = (w₀² -w²) 4 m²

Let's find the angular velocities

w₀² = 5 / 0.1

w₀² = 50

w = 2π f

w = 2π 1

w = 6.2832 rad / s

we subtitute

b² = (50 - 6.2832²) 4 0.1²

b = √ 0.42086

b = 0.6487 kg / s

How far can a bike rider traveling at 5.2 m/s go in 15 seconds

frez [133]

If he's traveling at 5.2 m/s, then he covers
5.2 meters in the 1st second
5.2 meters in the 2nd second
5.2 meters in the 3rd second
5.2 meters in the 4th second
.
.
.
.
5.2 meters in the 14th second, and
5.2 meters in the 15th second.

He covers 5.2 meters 15 times in 15 seconds.
To find the total distance, you could write down 5.2 meters
15 times and add them all up. Or you could use the newly-
discovered, labor-saving process called 'multiplication' to do
the same thing. With multiplication, it can be done in one line:

(5.2 m/s) x (15 sec) = 78 meters .
