Answer:
The scale factor is used to make models of real-life objects. For example, a toy car is modeled to look just like a real car but at a smaller size. The ratio of the toy car to the real car might be 1:24 1: 24 . Which means that for every one unit of length on the toy car, the real thing is 24 times that size.

BOOLEAN datatype is used for an attribute that takes a single character value.
It is incorrect to say that a Boolean datatype is used for an attribute with a single character value.
What exactly is the Boolean datatype?The Boolean data type is used in computer science to represent the two truth values of logic and Boolean algebra. It has one of two possible values (usually stated as true or false).
The Boolean Data Type can be used to represent two-state values such as true/false, yes/no, or on/off.
Boolean's default value is usually False. Boolean values are not grabbed as numbers, and the stored values are not required to be numerically equivalent.
Thus, the given statement is false.

what is road engineering
Explanation:
Road engineering is an engineering discipline branching from civil engineering that involves the planning, design, construction, operation, and maintenance of roads, bridges, and tunnels to ensure safe and effective transportation of people and goods. Road engineering became prominent towards the latter half of the 20th century after World War II. Standards of road engineering are continuously being improved. Road engineers must take into account future traffic flows, design of highway intersections/interchanges, geometric alignment and design, highway pavement materials and design, structural design of pavement thickness, and pavement maintenance.
a regular room is 8.7 m by 2.41 m. Which length of baseboard molding must be purchased to go around the perimeter of the floor?
When the regular room is 8.7 m by 2.41 m, the perimeter of the floor will be 22.22m.
What is perimeter?In geometry, the perimeter of a form is described as the whole length of its boundary. the fringe of a shape is determined through including the duration of all of the aspects and edges enclosing the form. it's far measured in linear devices of measurement like centimeters, meters, inches, or feet.
The perimeter system for a rectangle states that P = (L + W) × 2, where P represents perimeter, L represents duration, and W represents width. while you are given the size of a rectangular form, you may simply plug within the values of L and W into the method that allows you to clear up for the perimeter.
It should be noted that the perimeter will be:
= 2 (Length + Width)
= 2(8.7 + 2.41)
= 22.22m
Therefore, when the regular room is 8.7 m by 2.41 m, the perimeter of the floor will be 22.22m.

The refrigerant blends that are approved for use in MVAC systems can never be topped off never be recycled and re-charged into a system. The correct option is d.
What is MVAC system?Refrigeration is used in motor vehicle air conditioning (MVAC) equipment to cool the driver's or passenger's compartment. Section 609 of the Clean Air Act governs the maintenance of these systems.
The United States Environmental Protection Agency (EPA) currently does not require the recovery and recycling of natural refrigerants such as carbon dioxide; HCs such as propane, isobutane, blends such as R-441A, or ethane; or ammonia.
This is such a blatant air conditioning myth that it inspired the title of this blog post. You should never have to "top off" or "refill" the refrigerant in your air conditioner.

Kim deposits her annual bonus into a savings account that pays 8% interest compounded annuallyThe size of her bonus increases by $2,000 each year, and the initial bonus amount is $5,000. Determine how much will be in the account immediately after the fifth deposit
The amount that would be in Kim's account immediately after the fifth deposit would be $50,998.0
How to find the amount that would be in the accountWe have the amount in Year 0 to be the first deposit. This is given as $5000.
The formula used to calculate this is
P x (1+r) + T
Where P = principal
r = interest rate, hence 1 + 8% = 1.08
T is the increases of 2000
The bonus is said to increase by 2000 every year
2000 + 5000 = $7000
In year 1.
5000 x 1.08 + 7000
= 12,400
In year 2 add 2000 to 7000
(12,400 * 1.08) + 9000
= 22,392
Do the same for year 3
(22,392 * 1.08) + 11,000
= 35,183.36
Do the same for the 4th year
(35,183.36 * 1.08) + 13,000
= $50,998.0288
Therefore we can see that after the deposit is done 5 times the account would have $50,998.02 in it

An engineer places a small sample of a material on a horizontal disk whose surface is made of another material and then rotates the disk from rest with a constant angular acceleration of 4 rad/s2. Assuming that the coefficient of static friction between the sample and disk is 0. 2, what is the angular velocity of the disk at the time instant when the sample starts slipping on the disk?.
The critical value of the angular velocity obtained just before the slipping starts is the answer to this question and it is [tex]\bold{\omega = \sqrt{\frac{\mu.g}{r}}}[/tex].
Let's consider the sample to be a point object.There are 2 forces acting upon the sample when it is on the plane and rotating: the normal force from the plane and the friction force directed to the centre of the rotating axis.This friction force provides the centripetal force needed to continue the rotation on the disk keeping itself at rest on the disk relative to it.The reason for a slip is due to the lacking of this friction so that it is no longer capable of providing the required amount of centripetal force in the form of friction.The maximum friction is simply [tex]f_{max} = \mu_s.R[/tex] where [tex]R[/tex] is the normal force on the sample and [tex]\mu_s[/tex] the coefficient of static friction. By the vertical equilibrium [tex]R = mg[/tex] and that gives [tex]f_{max} = \mu_s. mg[/tex]The proper condition to continue the rotation without slipping is as follows and the critical value of angular velocity can be found from it.
[tex]\begin{aligned}\\\\F &= ma\\\\f_{max} &\geq ma\\\\ \mu_s.mg &\geq m.r\omega^2\\\\\omega &\leq \sqrt{\frac{\mu_sg}{r}}\\\\\omega_{critical} &= \sqrt{\frac{\mu_sg}{r}}\end{aligned}[/tex]
The critical angular velocity depends only on these parameters and for a given system it is dependent on where it is primarily placed from the centre of rotation (this question lacks this piece of data by the way).So this is the answer to this question and with the data for the constant angular acceleration, you can calculate how long it would take from the startup or how many rotations it would take until the point of slipping.For that, you can employ the formulae [tex]\omega = \omega_0+\alpha.\Delta t[/tex] and [tex]\omega^2 = \omega^2_0+2\alpha .\Delta \theta[/tex] respectively by putting [tex]\omega = \omega_{critical}[/tex].#SPJ4

The US navy recently funded the development of submersible drones to investigate shipwrecks located
on the ocean floor of the Marianas Trench. In this region of the world the ocean floor is located about
7.0 miles below sea level. Calculate the pressure a submersible drone would need to withstand 7 miles
below the surface of the ocean.
The pressure a submersible drone would need to withstand 7 miles is given to be 114.49 MPA
How to solve for the pressure of the submersible droneWer have P = rho x H
Where Rho s is the Sp x the weight of the sea water
= 10163 . 16n/m²
We are to proceed to find the value of H
H = 7. 0 miles below sea water
= 11265.408m
P = 11265.408m x 10163 . 16n/m²
= 114,492.144
= 114.49 MPA
