1: A baseball is hit 4 feet above the ground leaves the bat with an initial speed of 98 ft/sec at an angle of 0 45 is caught by an outfielder at a height of 3 feet.
Answer:
299.36 feet
Explanation:
[tex]To \ find \ the \ distance \ of \ the \ ball \ from \ the \ home \ plate. \\ \\ From \ the \ given \ information:[/tex]
[tex]Height \ h = 4 \ ft[/tex]
[tex]Initial \ speed \ V_o = 98 \ ft/s ec[/tex]
[tex]The \ angle \ \theta = 45^0[/tex]
[tex]Acceleration \ due \ to \ gravity (g)= 32.2 \ ft/s[/tex]
[tex]U_x = V_o \ cos 45 = \dfrac{98}{\sqrt{2}}[/tex]
[tex]U_y = V_o \ sin 45 = \dfrac{98}{\sqrt{2}}[/tex]
So;
[tex]S_y = u_y t - \dfrac{1}{2}gt^2[/tex]
[tex]-1 =\dfrac{98}{\sqrt{2}}t - \dfrac{1}{2}*32*1.85t^2[/tex]
By solving:
[tex]t_1 = 4.32 \ sec[/tex]
Thus;
[tex]horizontal \ distance = U_x t[/tex]
[tex]= \dfrac{98}{\sqrt{2}}\times 4.32[/tex]
[tex]\mathbf{=299.36 \ feet}[/tex]
[tex]\mathbf{Thus \ , the \ distance \ from \ the \ home \ plate \ = \ 299.36 \ feet}[/tex]
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.
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%

In the United States, a bicyclist is killed:
A. (Every 12 hours
B. Every week
c. Every day
D. Every 6 hours
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.

A pressure of elevation 4.8m on a tank containing oil read 34.7kpa.Another gauge at elevation 2.2m read 57 5kpa.Cumpute specific weight density and specific gravity of the liguid
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

Explanation:
To understand the concept of moment of a force and how to calculate it using a scalar formulation.
The magnitude of the moment of a force with a magnitude F around a point O is defined as follows:
MO=Fd
where d is the force's moment arm. The moment arm is the perpendicular distance from the axis at point O to the force's line of action.
A stool at a restaurant is anchored to the floor. When a customer is in the process of sitting down, a horizontal force with magnitude F1 is exerted at the top of the stool support. When the customer is seated, a vertical force with magnitude F2 is exerted on the stool support. If the maximum moment magnitude that the stool support can sustain about point A is MA = 160 Nm , what is the maximum height d1 that the stool can have if the magnitudes of the two forces are F1 = 300 N and F2 = 720 N . Assume that moments acting counterclockwise about point A are positive whereas moments acting clockwise about A are negative.
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 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 $0.10/kw-hr, determine the cost of operating the unit for 24hrs.
Solution :
Given :
The power of the air‐conditioning (AC) unit is , W = 0.434 kW
The coefficient of performance or the COP of the air‐conditioning (AC) unit is given by = 6.22
Therefore he heat removed is given by , [tex]$Q_H = 6.22 \times 0.434$[/tex]
[tex]$Q_H = 2.7 \ kW $[/tex]
Now if the electricity is valued at 0.10 dollar per kW hour, then the operating cost of the air conditioning unit in 24 hours is given by = 0.10 x 2.7 x 24
= 6.48
Therefore the operating cost = $ 6.48 for 24 hours.

In the context of electronics, the term "ground" is often used to refer to:
1: the negative battery terminal
2:the breadboard
3:the circuit diagram
4:the components
Which one is the answer
Answer:
1: the negative battery terminal
Explanation:
When we design and develop an electrical circuit in electrical and electronics engineering, it is important that we define a reference point for all electronic signals from which we can measure voltage. Although, the voltage passing through a reference point in an electrical circuit is typically 0 Volts.
Also, a ground is a common return path in an electrical circuit for the current flowing through the circuit.
When working on a direct current (DC) circuit that is mainly operated using a battery, the negative terminal of the battery would be the ground (reference point) for all the components connected to the electrical circuit.
Hence, in the context of electronics, the term "ground" is often used to refer to the negative battery terminal.

An NMOS transistor with kn = 1mA/V2 and Vt = 1V is operated with VGS = 2.5V. At what value of VDS does the transistor enter the saturation region? What value of ID is obtained in saturation?
Answer:
a) the point at which the transistor enters the saturation region is 1.5 v
b) the value of ID is obtained in saturation is 1.125 mA
Explanation:
Given the data in the question;
for an NMOS, the condition for the saturation is;
V_DS ≥ V_GS - V_t
V_GS is 2.5 v and V_t is 1 v
so we substitute
V_DS ≥ 2.5 - 1
V_DS = 1.5 v
so the point at which the transistor enters the saturation region is 1.5 v
The drain current I_d in the saturation region;
I_d = 1/2×μₙ×Cₐₓ×W/L×( V_GS - V_t)²
= 1/2Kₙ ( V_GS - V_t)²
our Kₙ is 1 mA/V², V_GS is 2.5v and V_t is 1 v
so we substitute
I_d = 1/2(1 mA/V²)( 2.5 - 1 )²
= 1/2(1 mA/V²)( 2.25)
= 1.125 mA
therefore, the value of ID is obtained in saturation is 1.125 mA
