What’s a transverse? (Definition)

No. Since the people selected were randomly, the responders constituted  random sample from the population.

Voluntary response sample is a sample which is made up of individuals who can volunteer to be included in response sample.

For example, If a radio host asks her listeners to conduct an online survey on her website about peoples opinion of her show. Each individual listener is voluntarily deciding to take part in survey or not.

The major drawback of sampling method is that these individuals who voluntarily respond is likely to have a stronger opinion which can be positive or negative from the rest of the population which eventually makes them an un-representative sample.

Total distance traveled by an object traveling at an average speed of

0.0470 km/h for 2min 33s is 1.99 m.

Distance is defined as an object's entire movement without regard for direction. Distance may be defined as how much ground an item has traversed regardless of its starting or finishing place.

The following equation can be used to determine the distance traveled by an object traveling at an average speed:

distance traveled = average speed * time

When is this:

Given,

average speed = 0.0470 km/h

converting average speed from km/h to m/s

                           = 0.01305556 m/s

time = 2min 33s

converting time in seconds

       = 153s

thus, we know that

distance traveled = average speed * time

                              = 0.01305556 * 153

                              = 1.99 m

Therefore, the Total distance traveled by the object is 1.99m.

When Fez engages in team activities such as running or passing the ball, they are maintaining tension with an equal force on all sides.

Any physical object that is in contact with another one can apply forces to that object. The pulling force transmitted axially by a string, cable, chain, or other similar object, or by each end of a rod, truss member, or other similar three-dimensional object is referred to as tension. The action-reaction pair of forces acting at each end of said elements can also be referred to as tension.

The force produced when a load is applied at one or more of the ends of a material in a direction away from the material's cross-section is known as the tension force. It's common to describe a tension force as a "pulling" force. To exert a tension force on the material, the load must be applied axially.

The magnitude of the unit vector of the forces is 182.92 N and the direction is 56.87⁰.

A unit vector is a type of quantity that has both magnitude and direction.

A unit vector can also be described as a single vector that can represent two vectors in terms of magnitude and direction.

A resultant vector is defined as a single vector that produces the same effect as is produced by a number of vectors collectively.

The unit vector of the two forces is calculated as follows;

R² = Fx² + Fy²

where;

R = √( Fx² + Fy²)

R = √( 100² + 153.2²)

R = 182.95 N

The direction of the vector is calculated as follows;

θ = arc tan (Fy/Fx)

θ = arc tan (153.2 / 100)

The effect after the current is tripled is changing the drift velocity by a factor 3.

We need to know about drift velocity of electrons to solve this problem. The drift velocity can be determined as

v = I / (n . A . q)

where v is drift velocity, I is current, n is atom number density, A is surface area and q is the charge.

From the question above, we know that

I2 = 3 . I1

According to drift velocity formula, the drift velocity is proportional to current

v ~ I

Hence, the ratio of drift velocity and current is

v1 / v2 = I1 / I2

substitute the final current (I2)

v1 / v2 = I1 / (3.I1)

v1 / v2 = 1 / 3

v2 = 3v1

The rate of change of the area of the triangle if the height is 7cm is 38.5 cm/s

What is Rate of change?

A rate is anything that can be measured over time. Common rates include velocity (which is the rate of distance traveled), power (rate of work being done), etc. All these have one thing in common which is that they are all divided by the amount of time it took to obtain a certain measurement.

Let the base of the triangle be b,

the height of the triangle = h

and the area of the triangle = A

Area of a triangle, A is = bh/2

Rate of change of the area, A is :

dA/dt = d(1/2(bh))/dt = 1/2 (db/dt)h + 1/2(bdh/dt)

At constant height, dh/dt = 0

that is

dA/dt = 1/2(db/dt)h

It is given that :

db/dt = 11 cm/s

h = 7cm

dA/dt = (11x7)/2  = 38.5 cm/s

If the sound intensity goes up by 40 db, the amplitude of wave as measured gets increases by a factor of 100.

The sound level in decibels can be formulates as

[tex]\beta[/tex] = (10dB) log (I/Io)

Here Io = 10⁻¹²W/m² is specified as the reference intensity

If we assume β₁ as initial sound intensity and β₂ as final sound intensity. Therefore, change in sound intensity can be formulated as

β₁-β₂=40 dB

(10dB) log (I2/Io) - (10dB) log (I1/Io) = 40 dB

(10dB) [log (I2/Io) - log (I1/Io)] = 40dB

log( (I2/Io) / (I1/Io) ) = 40/10 dB

log (I2/I1) = 4dB

I2/I1 = 10^4

The intensity of sound is said as directly proportional to the amplitude of wave squared.

Therefore,

I ∝ A²

I1/I2 = (A1/A2)^2

A2/A1 = [tex]\sqrt{I2/I1}[/tex]

A2/A1 = 100

Therefore, the amplitude of wave increases by a factor of 100.

A sound wave’s amplitude measures the height of the wave. When a sound is made, the maximum displacement of the medium’s vibrating particles from their mean position determines the amplitude of the sound wave.

In physics, amplitude refers to the greatest displacement or distance that a point on a vibrating body or wave can move relative to its equilibrium location. It is equivalent to the vibration paths half-length.

The maximum displacement of a sound wave’s constituent particles is its amplitude. The number of vibrations a sound wave makes per second is known as frequency.

The explanation on how the rudders turn the boat​ is by redirecting the fluid  which results in an opposite force aiding the motion of the boat.

This law was coined by Isaac Newton and it states that when object X exerts a force on another object Y, the object Y must exert a form of counter force which has the same magnitude but opposite in direction.

In the case of the rudder, it redirects the fluid which then exerts an equal force of the same magnitude and an opposite direction. This thereby results in the motion of the boat and is therefore the most appropriate choice.

The frequency of electromagnetic waves is 22.32 x 10⁹ Hz or 22.32 GHz.

We need to know about electromagnetic waves to solve this problem. Electromagnetic waves can propagate without media. The speed of electromagnetic in vacuum media is equal to the speed of light. Hence, the wavelength and frequency can be determined as

c = λ . f

where c is the speed of light (3 x 10⁸ m/s), λ is wavelength and f is frequency.

From the question above, we know that

λ = 13.44 mm = 0.01344 m

By substituting the given parameter, we can calculate the frequency of microwaves

c = λ . f

f = c / λ

f = 3 x 10⁸ / 0.01344

f = 22.32 x 10⁹ Hz
