The first formant of your vocal system can be modeled as the resonance of an open-closed tube, the closed end being your vocal cords and the open end your lips. Estimate the frequency of the first formant from the graph in (Figure 1).

Answer:

Friction drag force causes objects to slow down as they move through a fluid, such as air or water. ... As an object's speed increases, the drag force from the fluid increases exponentially. • For example, when you drive at high speeds, the frictional force of air on the car increases, and fuel economy decreases.

Hi there!

Given the values for α and β, we can plug these into the given equation:

[tex]v(t) = 4t - 2t^2[/tex]

Begin by solving for the velocity at t = 0 and t = 3:

At t = 0:
[tex]v(0) = 4(0) - 2(0^2) = 0 \frac{m}{s}[/tex]

At t = 3:
[tex]v(3) = 4(3) - 2(3^2) = 12 - 18 = -6 \frac{m}{s}[/tex]

Acceleration is the SLOPE of the velocity graph (its derivative), so we can use the kinematic equation:

[tex]a = \frac{v_f - v_i}{\Delta t}[/tex]

Plug in the knowns:

[tex]a = \frac{-6-0}{3 - 0} = \boxed{-2 \frac{m}{s^2}}[/tex]

[tex] \frac{4577}{7 \times (80 - ( - 12))} \\ \frac{4577}{7 \times92 } \\ \frac{4577}{644} \\ = 8.5g[/tex]

The width of the printer is 0.4572 meters.

The metric conversion system is a standardized system of measurement based on the International System of Units (SI). It is used by scientists, engineers, and many others around the world to ensure consistency and accuracy in measurement.

The system is based on a series of prefixes that can be added to a base unit of measurement to create multiples or fractions of that unit. For example, the prefix "kilo-" means "thousand," so one kilometer is equal to 1,000 meters. The metric system is widely used in scientific and technical fields and is also the official system of measurement for many countries.

To convert inches to meters, we can use the conversion factor 1 inch = 0.0254 meters.

So, the width of the printer in meters is:

18 inches x 0.0254 meters/inch = 0.4572 meters

Explanation:

Here it's given that the weight of the box is 4N and it slides across a rough table for a distance of 2m . And we are interested in finding out the work done by the weight of the block. Firstly we know that , Work done is ,

[tex]\rm\longrightarrow \pink{ Work\ = \ F.s = |F||s|cos\theta} [/tex]

where

Therefore ,

[tex]\rm\longrightarrow Work = (4N)(2m)(cos\theta) [/tex]

Here the angle between the displacement and force is 90° , and value of cos90° is 0 , therefore,

[tex]\rm\longrightarrow Work = 8N-m (0)\\[/tex]

[tex]\rm\longrightarrow \underline{\boxed{\rm\blue{Work = 0 }}}[/tex]

The work done by the weight of the box is zero. The correct answer is zero. The correct option is (E).

Given:

Weight of the box = 4.00 N (acting downward)

Distance = 2.00 m

The angle between force and displacement, θ = 90°

Using the formula for work:

Work (W) = Force × Distance × cos(θ)

Since the angle θ is 90 degrees and cos(90 degrees) = 0.

The work done by the weight of the box is:

W = Force × Distance × cos(90)

W = 4.00 × 2.00 × 0

W = 0 J

Therefore, the work done by the weight of the box is zero. The correct option is (E).

Based on the data provided;

The formula for calculating density is given as:

From the formula above;

mass = density × volume

also, volume = area × height

Therefore,

mass = density × area × height

Calculating for the height of the liquid:

Height, L = 90.8 / (0.86 × 6.08)

L = 17.2 cm

The pressure due to a liquid is calculated using the formula below:

where;

h is height = 17.2 cm = 0.172 m

P is density = 0.86 g/cm^3 = 860 kg/m^3

g is acceleration due to gravity = 9.8 m/s^2

Pressure = 860 kg/m^3 × 0.172 m × 9.8 m/s^2

You walk from chisale to st Francis a distance of 6km/h and 50minutes,  the average speed in m/s​ will be 2m/s

The average speed of a moving object is defined as the total distance covered by it divided by the total time taken.

The S.I unit of speed is meter per second. Speed is also measured in kilometer per hour.

Average speed is a scaler quantity

Average speed is the total distance travelled by an object to the total time taken. However, average velocity is the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs. No matter how many times the speed has been changed to travel the entire distance , average speed is that constant speed value with which one can travel by and reach the same distance in same amount of time .

It can be calculated with a formula average speed = distance / time

given

distance = 6 km = 6000 m

time = 50 minutes = 50 * 60 = 3000 sec

average speed = distance / time

                          = 6000 / 3000 = 2m/s

Answer: The resultant displacement vector is 5.6km

The resultant displacement vector of the hiker is equal to 5.6 km.

The distance can be described as the total length traveled by an object and is a scalar quantity with only magnitude. The distance should be always positive.

The displacement of an object can be described as the shortest length between two points. The displacement can be considered as a vector quantity with direction & magnitude. The displacement can be +ve, -ve, or zero and can be changed with time.

Given, a hiker moves 5.0 km along AB in the North and then 2.5 km west along BC.

The length (AC) is the resultant displacement that can be calculated by using Pythagoras' theorem:

AC² = AB² + BC²

AC² = (5.0)² + (2.5)²

AC² = 25 + 6.25

AC = 5.59 km ≈ 5.6 km

Therefore, the displacement of the hiker is 5.6 Km.

Explanation:

The radius of each jawbreaker is approximately 0.68 cm.

where

r = radius

Therefore,

23 g  = 32.3 cm³

0.94 g  = ?

cross multiply

volume of a single jawbreaker = 32.3 × 0.94 / 23 = 30.362 / 23 = 1.32 cm³

Therefore,

volume of each jawbreaker = 4 /3 πr³

1.32 = 4 / 3 × 3.14 × r³

r³ = 1.32 /4.18666666667

r³ = 0.31533683707

Explanation:

The advantage of protecting entire ecosystems is the most effective way to save species because species confined to a small area could be wiped out by a single natural disaster. Some species require a large range to find adequate food or mate. Therefore, protecting the habitats of endangered and threatened species often means preserving or managing large areas (entire ecosystem).
