Answer:

It is critical for the upper and lower end sections of an engine to work perfectly together because they are responsible for converting fuel into motion, which is necessary for the engine to operate effectively.

The upper end section of an engine includes the cylinder head and valves, which are responsible for controlling the flow of fuel and air into the engine. The lower end section of an engine includes the crankshaft, connecting rod, and pistons, which are responsible for converting the fuel's energy into rotational motion.

If the upper and lower end sections of an engine are not working perfectly together, it can lead to a variety of problems, including reduced engine performance, reduced fuel efficiency, and increased emissions. It is therefore critical for the upper and lower end sections to be carefully designed and calibrated to work together seamlessly in order to ensure the optimal performance of the engine.

The number of gallons in a swimming pool in the given question can be classified as a ratio level measurement.

The highest of the four hierarchical levels of measurement is the ratio level measurement. Data recording accuracy is determined by the levels or scales of measurement. The measurement becomes more difficult as the level increases.

The features of the other 3 levels are all present in the ratio level. At the ratio level, values can take on a true zero, be categorised, ordered, have equal intervals, and more.

While interval and ratio variables are quantitative variables, nominal and ordinal variables fall under the category of categorical variables. Quantitative data allows for a much wider range of statistical tests than categorical data.

Explanation:

Given that,

Mass,

m = 1.6 mg

or,

   = 1600 kg

Initial velocity,

u = 72 km/h

  = [tex]72\times \frac{5}{18} \ m/s[/tex]

  = [tex]20 \ m/s[/tex]

Final velocity,

v = 18 km/h

  = [tex]18\times \frac{5}{18}[/tex]

  = [tex]5 \ m/s[/tex]

Covered distance,

s = 250 m

By using the below relation, we get

⇒  [tex]v^2=u^2+2as[/tex]

On putting the values, we get

⇒  [tex](5)^2=(20)^2+2\times a\times 250[/tex]

The principal of the loan that TMI Systems repaid was $90,000.

The formula to calculate the principal of a loan is P = L + I, where P is the principal, L is the loan amount, and I is the total interest paid over the duration of the loan.

In this case, we are given that the loan amount was 10% per year simple interest, which can be calculated by multiplying the principal by the interest rate (0.1) and the duration of the loan (5 years). Therefore, the total interest paid over the duration of the loan is P x 0.1 x 5 = $50,000.

We are also given the total amount repaid, which is the sum of the principal and the total interest paid. Therefore, we can calculate the principal by subtracting the total interest paid from the total amount repaid.

This gives us $140,000 - $50,000 = $90,000. As the principal must be a positive value, the principal of the loan is $90,000.

Using the formula of shear stress, the minimum required diameter is 0.81mm

Shear stress is a force that causes two objects to slide past each other in opposite directions. It is the force per unit area of the surface on which the force is applied. Shear stress is often caused by two objects rubbing against each other, such as a car tire sliding on the road. It can also be caused by wind, gravity, or other forces.

The shear stress on the shaft can be calculated using the formula:

τ(allow) = P/(2*π*d*J)

where P is the total power transferred by the shaft, d is the diameter of the shaft, and J is the polar moment of inertia.

J = π*d⁴/32

Substituting the given values,

τ(allow) = (15 + 6 + 4 + 5)/(2*π*d*π*d⁴/32)

d = √[32*(15 + 6 + 4 + 5)/(τ(allow)*2*π²)]

d = √[32*(30)/(75*2*π²)]

d = 0.81mm

The minimum required diameter of the shaft is 0.81 mm to the nearest millimeter.

The equation for the streamline passing through point (2,5) is y-5=b/a(x-2).

Streamlining is a process of simplifying or improving a process or system to increase efficiency, reduce complexity, and reduce costs. It can involve reorganizing, restructuring, rearranging, or redefining a system, procedure, or process to make it more efficient and productive.

B) At t=2, the coordinate of the particle that passed through point (0,4) at t=0 is (6,7). This is because since the velocity field is V = ayibxj, the particle will experience a displacement of 2a in the x-direction and 2b in the y-direction in the span of 2 seconds. Thus, the displacement of the particle is (2a,2b) = (4,2). Adding this to the initial position (0,4), the new position of the particle is (4,6).
C) At t=3, the coordinate of the particle that passed through point (1,4.25) 2 seconds earlier is (7.25,6.25). This is because since the velocity field is V = ayibxj, the particle will experience a displacement of 3a in the x-direction and 3b in the y-direction in the span of 3 seconds.

To solve this, let's build some relationships among the power, voltage, current and number of loops in an ideal transformer.

For an ideal transformer, the powers generated by the primary and secondary coils are the same. In other words, the input power and output power remain the same.

Input power = Output power

Where;

Input power = [tex]V_{p}[/tex] x [tex]I_p[/tex]

Output power = [tex]V_{s}[/tex] x [tex]I_s[/tex]

=> [tex]V_{p}[/tex] x [tex]I_p[/tex] = [tex]V_{s}[/tex] x [tex]I_s[/tex]

This can be re-written as:

[tex]\frac{V_p}{V_s}[/tex] = [tex]\frac{I_s}{I_p}[/tex]             ------------------(i)

Also, the transformer turns ratio (r) is the quotient of the number of turns/loops in the primary coil and the number of turns/loops in the secondary coil. i.e

r = [tex]\frac{N_p}{N_s}[/tex]

This ratio is equal to the ratio given in equation (i) i.e

r = [tex]\frac{N_p}{N_s}[/tex] = [tex]\frac{V_p}{V_s}[/tex] = [tex]\frac{I_s}{I_p}[/tex]

=> r = [tex]\frac{N_p}{N_s}[/tex] = [tex]\frac{V_p}{V_s}[/tex]

=> [tex]\frac{N_p}{N_s}[/tex] = [tex]\frac{V_p}{V_s}[/tex]

This can be re-written as

=> [tex]\frac{N_s}{N_p}[/tex] = [tex]\frac{V_s}{V_p}[/tex]       -----------(ii)

From the question,

[tex]V_{p}[/tex] = 120V

[tex]V_{s}[/tex] = 100kV = 100000V

Substitute these values into equation (ii) as follows;

[tex]\frac{N_s}{N_p}[/tex] = [tex]\frac{100000}{120}[/tex]

[tex]\frac{N_s}{N_p}[/tex] =  [tex]\frac{10000}{12}[/tex]

[tex]\frac{N_s}{N_p}[/tex] =  [tex]\frac{2500}{3}[/tex]

Therefore, the ratio of the number of loops in the secondary to the number of loops in the primary is 2500 : 3
