λ = 3.125 m

λ = 2.83 m

<h3>Further explanation</h3>

Given

Frequency of radio : 96 MHz and 106 MHz

Required

The wavelength

Solution

Wavelength : from the crest to the crest of the next wave or the trough to the trough

Frequency (f): number of waves in one second

v = λ x f

λ = v : f

Input the value :

f = 96 MHz = 96 x 10⁶ Hz

λ = v : f

λ = 3 x 10⁸ :  96 x 10⁶

λ = 3.125 m

f = 106 MHz = 106 x 10⁶ Hz

λ = v : f

λ = 3 x 10⁸ :  106 x 10⁶

λ = 2.83 m

A) Draw a pie chart that represents the two types of lung cancer. Show your working.
Sphinxa [80]

Answer:

<em>Please, check the image provided</em>

Explanation:

<u>Pie Charts</u>

They are graphic representations of quantitative results from experimental or theoretical experiences. Instead of showing a table, it's usually preferred to show a graph where the viewer can easily understand the relative relations between the parameters under study.

The chart pie is a circular shape divided into sectors whose areas are proportional to the proportions between each parameter and the total. Since the whole sector of a circle has 360°, each sector will be a proportion or ratio of that angle.

The outcome shown in the table gives us these statistics:

Small Cell Carcinoma : 15%

Non-Small Cell Carcinoma : 85%

Each category has the following angles in the chart pie

Small Cell Carcinoma : 15%*360°=54°

Non-Small Cell Carcinoma : 85%*360°=306°

The first category is shown in blue and the second in green. Please check the image below.

A resistor, an inductor, and a switch are all connected in series to an ideal battery of constant terminal voltage. What does th
Irina-Kira [14]

Answer:

The time constant τ = L/R represent the time requiered for the curent to get value of 63 % of its maximun value

Explanation:

In a circuit RL ( serie circuit with a resistor R and the inductor L ) when a voltage is applied the inductor will have a reaction, such reaction consist in the creation of an electromotive force which will prevent the current to get its maximun value. The time constant which in the case of an inductor is

τ = L/R ,  represent the time requiered for the crrent to be 63 % of its final value

How large must the coefficient of static friction be between the tires and the road if a car is to round a level curve of radius
maria [59]

Answer:

897

Explanation:

Speed of the car, v = 126 km/h, converting to m/s, we have v = 35 m/s and

Radius of the curve, R = 150 mm = 0.15 m

The centripetal acceleration a(c) is given by the formula = v² / R so that

a(c) = 35² / 0.15

a(c) = 1225 / 0.15

a(c) = 8167 m/s²

The force that causes the acceleration is frictional force = µ m g, where

µ = coefficient of friction

m = the mass of the car and

g = acceleration due to gravity, 9.81

From Newton's law:

µ m g = m a(c) , so that

µ = a(c) / g

µ = 8167 / 9.81

µ = 897

Therefore, the coefficient of static friction must be as big as 897
