In the United States, a bicyclist is killed:
A. (Every 12 hours
B. Every week
c. Every day
D. Every 6 hours
Answers
In the United States, it should be noted that a bicyclist is killed every six hours.
The cause of the accidents has been attributed to the rough driving of vehicle drivers and some faults are on the part of the cyclist as well.
Rapidly overtaking a bicycle is dangerous. Also, there are some vehicle drivers who drive into the lanes that are meant for cyclists. This isn't appropriate.
Drivers should ensure that they are not close to the cyclists when driving as there should be a space of at least 3 feet between the bicycle and the vehicle.
Furthermore, when there is a narrow traffic lane, the vehicle drivers should ensure that there's a clear traffic in the opposite lane before they change their lanes.
Lastly, both the cyclists and the vehicle drivers should not overspeed and drive safely.
Based in the information given above, the correct option is D.

Answers
Answer:
Explanation:
From the given information:
Pressure at the elevation 4.8 m = 34.7 kPa
Pressure at the elevation 2.2 m = 57.5 kPa
Recall that:
At the pressure of depth "h";
p = ρgh
where;
ρgh = 34.7 × 10 ³
ρ × 9.81 × h = 34.7 × 10³
ρh = 34.7 × 10³/9.81
ρh = 3.54 × 10³ ----- equation (1)
ρg(h + 4.8 - 2.2) = 57.5 × 10³
ρ × 9.81 × (h + 2.6) = 57.5 × 10³
ρ (h + 2.6) = 57.5 × 10³ / 9.81
ρ (h + 2.6) = 5.86 × 10³ ------ equation (2)
From equation (1) and (2);
The density of the oil ρ is determined to be = 0.8939 × 10³ kg/m³
≅ 893.9 kg/m³
The specific weight w = ρg
w = 0.8939 × 10³ × 9.81
w = 8769.159
w = 8.75 × 10³ kg/m²/s²
The specific gravity SG = [tex]\dfrac{\rho _{oil}}{\rho_{water}}[/tex]
= [tex]\dfrac{0.8939 \times 10^3}{10^3}[/tex]
= 0.8939
≅ 0.894

Consider a second cosine waveform y(t) with the peak value of 10A and frequency of 60Hz. Calculate the power throughtput wherein x(t) and y(t) can be assumed to be the voltage waveform and the current waveform respectively across the two terminals.
Answers
Answer:
power = 0
Explanation:
Given data:
cosine waveform; y(t) = 10cos(120πt)
peak value = 10A
frequency = 60 Hz
Calculate power throughout given x(t) and y(t) are assumed to be voltage waveform and current waveform
y(t) = 10cos(120πt)
frequency of x(t) = 100 Hz
frequency of y(t) = 60 Hz
power = IV where frequency is constant/similar
from the above it can be seen that frequency differs for x and y components hence power = 0

B. a model
Explanation:
A three-dimensional rendering of a product concept is called a model.
An example of a model used in computer programming is the software development life cycle (SDLC) model.
Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.
Some of the models used in the software development life cycle (SDLC) are;
I. A waterfall model: it can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.
II. An incremental model: it refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.
III. A spiral model: it can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.

A sample of soil has a volume of 0.45 ft^3 and a weight of 53.3 lb. After being dried inan oven, it has a weight of 45.1 lb. It has a specific gravity of solids of 2.70. Compute its moisture content and degree of saturation before it was placed in the oven.
Answers
Answer:
a) the moisture content before it was placed in the oven is 18.18%
b) degree of saturation for soil is 72.19%
Explanation:
Given the data in the question;
Moisture Content = [(Weight of soil before dry - dry weight) / dry weight] × 100
so we substitute
Moisture content = [(53.3 - 45.1) / 45.1 ] × 100
= (8.2/45.1) × 100
= 18.18%
Therefore the moisture content before it was placed in the oven is 18.18%
Dry Unit Weight = dry weight / volume
Dry Unit Weight = 45.1 lb / 0.45 ft³
Dry Unit Weight = 100.22 lb/ft³
we know that;
dry unit weight = (Specific gravity × unit weight of water) / (1 + e)
we also know that; unit weight of water is 62.43 lbf/ft³
so we substitute
e = (2.70×62.43 / 100.22) - 1
e = 1.68 - 1
e = 0.68
so void ratio e = 0.68
Now we determine the degree of saturation using the equation;
degree of saturation = (Moisture content × specific gravity) / void ratio
we substitute
degree of saturation = ( 18.18% × 2.7) / 0.68
= 0.49086 / 0.68
= 0.7219 ≈ 72.19%
Therefore degree of saturation for soil is 72.19%

Answers
Answer:
When analyzing forces in a structure or machine, it is conventional to classify forces as external forces;
constraint forces or internal forces.
External forces arise from interaction between the system of interest and its surroundings.
Examples of external forces include gravitational forces; lift or drag forces arising from wind loading;
electrostatic and electromagnetic forces; and buoyancy forces; among others. Force laws governing these
effects are listed later in this section.
Constraint forces are exerted by one part of a structure on another, through joints, connections or contacts
between components. Constraint forces are very complex, and will be discussed in detail in Section 8.
Internal forces are forces that act inside a solid part of a structure or component. For example, a stretched
rope has a tension force acting inside it, holding the rope together. Most solid objects contain very
complex distributions of internal force. These internal forces ultimately lead to structural failure, and also
cause the structure to deform. The purpose of calculating forces in a structure or component is usually to
deduce the internal forces, so as to be able to design stiff, lightweight and strong components. We will
not, unfortunately, be able to develop a full theory of internal forces in this course – a proper discussion
requires understanding of partial differential equations, as well as vector and tensor calculus. However, a
brief discussion of internal forces in slender members will be provided in Section 9.

a) cos(2pi0.15n)
b) cos(2n);
c) cos(pi0.3n) + cos(pi0.4n).
Answers
Answer:
a) it is periodic
N = (20/3)k = 20 { for K =3}
b) it is Non-Periodic.
N = ∞
c) x(n) is periodic
N = LCM ( 5, 20 )
Explanation:
We know that In Discrete time system, complex exponentials and sinusoidal signals are periodic only when ( 2π/w₀) ratio is a rational number.
then the period of the signal is given as
N = ( 2π/w₀)K
k is least integer for which N is also integer
Now, if x(n) = x1(n) + x2(n) and if x1(n) and x2(n) are periodic then x(n) will also be periodic; given N = LCM of N1 and N2
now
a) cos(2π(0.15)n)
w₀ = 2π(0.15)
Now, 2π/w₀ = 2π/2π(0.15) = 1/(0.15) = 1×20 / ( 0.15×20) = 20/3
so, it is periodic
N = (20/3)k = 20 { for K =3}
b) cos(2n);
w₀ = 2
Now, 2π/w₀ = 2π/2) = π
so, it is Non-Periodic.
N = ∞
c) cos(π0.3n) + cos(π0.4n)
x(n) = x1(n) + x2(n)
x1(n) = cos(π0.3n)
x2(n) = cos(π0.4n)
so
w₀ = π0.3
2π/w₀ = 2π/π0.3 = 2/0.3 = ( 2×10)/(0.3×10) = 20/3
∴ N1 = 20
AND
w₀ = π0.4
2π/w₀ = 2π/π0. = 2/0.4 = ( 2×10)/(0.4×10) = 20/4 = 5
∴ N² = 5
so, x(n) is periodic
N = LCM ( 5, 20 )

A window‐mounted air‐conditioning unit (AC) removes energy by heat transfer from a room, and rejects energy by heat transfer to the outside air. At steady‐state, the AC cycle requires 0.434kW and has a coefficient of performance (COP) of 6.22. Determine the rate at which the energy is removed from the room air, in kW. If electricity is valued at $0.10/kw-hr, determine the cost of operating the unit for 24hrs.
