Transformers are devices used to increase or decrease AC voltages with very little waste of
energy. Step-up transformers allow a device such as a television tube, which may need
25,000 V, to get the voltage it needs from a wall outlet that usually supplies only 120 V.
Likewise, a step-down transformer can allow a small device, such as a battery charger, to be
supplied from the same outlet with as little as 1.5 V.
Imagine that you had to construct a transformer capable of running a television set that was
going to be plugged into a conventional 120 V outlet that was on a 15 A line. On the primary
coil of your transformer are 200 turns.

4. How long must a 25° ramp be to slow to a momentary stop a runaway truck moving along a truly horizontal highway at
85 miles per hour?
Answers
A 25° ramp must be 174.4 m long to slow to a momentary stop a runaway truck moving along.
What is velocity?The rate at which a body's displacement changes in relation to time is known as its velocity. Velocity is a vector quantity with both magnitude and direction.
Initial velocity: u = 85 mile/hour = 85 × 0.45 m/s = 38.0 m/s
Acceleration due to gravity: g = 9.8 m/s²
As the ramp is 25° inclined, the deceleration: a = g sinα = 9.8×sin25° m/s² = 4.14 m/s².
Hence, required distance = u²/2a = 38.0²/(2×4.14) = 174.4 m.

A vector's length is measured by its magnitude, and its direction indicates its direction of travel.
What is the magnitude and direction?The magnitude of a vector denotes its length, and the direction indicates its direction. There are several ways to express vector direction, but degrees are the most used. Examples of vectors are acceleration and velocity.
Given a location vector v=a,b, the magnitude is calculated using the formula |v|=a2+b2. Depending on the application, the direction is equal to the angle made with either the x- or y-axis.
The angle a vector makes with a horizontal line determines its direction. Tan is equal to y2 y1x2 x1, where x1,y1 and x2,y2 are the starting and ending points, respectively.

Fiducial marks are a set of marks that can be found in the corners, edge-centers, or both of an aerial photographic image. The camera captures these traces on the original film.
Given the Ryerson Campus is at a scale of 1:1000
Then the photographic scale (s) = 1:3000
The focal length of camera (f) = 152mm = 0152m
The format is (k) = 230 x 230mm = 0.23m
the photographic scale (s) = F/H where H is the image height
1/3000 = 0.152 /H Then H = 456m
Assume that there is longitudinal overlap as P1 = 60% and side to side overlap as 30%. Therefore margin of ground photograph = (1-P1) x k/s
(1-0.6) x 0.23/1/3000 = 276mm
Now width of ground photograph = (1-0.3) x 0.23/1/3000 = 483m

Differentiate between Low Pass,high Pass, Band Pass and Band Stop Filters stating One(1) use of each.
Answers
These filters each have a different purpose and can be used according to the requirement.
A low-pass filter is a filter that allows signals with frequencies lower than a certain cutoff frequency to pass while attenuating signals with frequencies greater than the cutoff frequency. The frequency response of the filter is determined by its design. Low-pass filters are used in audio amplifiers, equalizers, and speakers and have applications such as anti-aliasing, reconstruction, and speech processing.
A high-pass filter is an electrical filter that allows signals with frequencies higher than a specific cutoff frequency to pass while attenuating sounds with frequencies lower than the cutoff frequency. The degree of attenuation for each frequency is determined by the filter design. A high pass filter is used to eliminate undesirable noises at the bottom of the audible range.
A band-pass filter, is a device that passes frequencies within a specific range while rejecting frequencies outside of that range. Band-pass filter functions are employed when it is intended to transmit signals within a specific frequency band while blocking signals at lower and higher frequencies. This is what "tuning" a desired frequency, such as a radio or television transmission, entails.
A band-stop filter, also known as a band-rejection filter, is a signal processing filter that passes most frequencies unmodified while attenuating those in a certain frequency range to very low levels. It's the inverse of a band-pass filter. A band stop filter is commonly used in audio signal processing to remove a specified range of undesired frequencies of sound, such as noise or hum, without attenuating the remainder.

Answers
The distance between jeep and car when the bullet strikes the car is 193.32m.
What are the five distinctions between velocity and speed?A scalar quantity, speed. It just has magnitude. A vector quantity is velocity. It has a direction as well as a magnitude. Speed is defined as the sum of the traveled distance (d) and the elapsed time (t). A body's speed determines how quickly it moves. In a straight line, uniform motions have the same speed and velocity. Then, everything will be identical.
Speed of jeep = 60km/hr= 16.7m/s
Speed of car = 72km/hr = 20m/s
The distance between car and jeep is 200m.
The speed of bullet = 500 m/s
The resultant speed of bullet and jeep = 16.7+500= 516.7m/s
The velocity at which bullet strikes the car => 516.7 - 20
=> 496.7m/s
Time take for bullet to strike = 200/496.7= 0.4s
The jeep traveled at a distance = 0.4 x 16.7 = 6.68m
Hence, the distance between jeep and car reduced to 193.32m.

Hence, the total number of electrons removed = net change of the object ÷ charge of each electrons
= 0.560 × 10⁻⁶ Coulomb ÷ 1.6 × 10⁻¹⁷ Coulomb.
= 3.5 × 10¹⁰ .

Locate the virtual F Prescribe a suitable bi-focal spectacles for a person who cannot see clearly the object nearer than 50 cm and 2 m/away or further. 75
Answers
The virtual focus of a person is -2m and the power of bi focal spectacles for a person who can see between 50cm and 2m is -0.5D
What distinguishes actual focus from virtual focus?The true focus is the location of the actual convergence, while the virtual focus is the location from which the diverging rays appear to arise as they are stretched backward. In the case of a convex lens, real focus is attained, and in the case of a concave lens, virtual focus is attained.
Visible object distance (u)= 2m
Image distance (v) = infinity
Focal length (f) formula => 1/v - 1/u = 1/f
=> 1/infinity - 1/2 = 1/f
=> f = -2m
The relation between power (P) and focal length (f) => P = 1/f
P = 1/-(2) => -0.5D
What is presbyopia identified as?The ciliary muscles gradually become less flexible and the eye lens becomes less flexible, which leads to presbyopia. A bifocal lens is used to repair the problem in eyes that have both myopia and hypermetropia.

, which type length? of mirror has & positive focal length?
Answers
Because the focus of a convex mirror is on the right side and behind the mirror, it has a positive focal length.
Is the focal length of a concave mirror positive?Conventionally, distances along the central axis are measured as positive from the mirror toward the object and negative away from the object. As a result, the focal length and radius of curvature are positive for concave mirrors and negative for convex mirrors.
What kind of lens has an increased focal length?The focal length is always positive for converging lenses and always negative for divergent lenses. This is done according to sign convention in ray optics.

The force acting on the 0.10 kg apple with a velocity of -5.88 m/s and time of 0.6 sec is 0.98 Newton.
What is force?Any action that has the ability to alter, maintain, or modify a body's motion is considered a force in mechanics. Isaac Newton's Principia Mathematica has three laws of motion that are usually used to explain the concept of force (1687).
A body at rest or consistently moving in a straight path is said to remain in that state until a force is applied to it, according to Newton's first law. A body will accelerate (change in velocity), in accordance with the second rule, in the direction of any external force acting on it.
Calculate the change in velocity as shown below,
V = -6.86 - (-0.98)
V = -5.88
The time for this change in velocity,
T = 0.70 - 0.10
T = 0.6
Calculate the force as shown below,
Force = 0.10 × (-5.88) / 0.6
Force = -0.588 / 0.6
Force = -0.98 N
Thus, the force acting on the apple is 0.98 Newton.
