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

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.

GIVING BRAINLIEST
Answers
Mechanical kinetic energy is the energy of an object due to its motion.
a) Mechanical kinetic energy = (1/2)*mass*(velocity)^2
Mechanical kinetic energy = (1/2)*(6.80 x 10^3 kg)*(23.7 m/s)^2
Mechanical kinetic energy = 3.27 x 10^7 J
b) The mechanical kinetic energy of a moving object can be calculated using the following formula:
KE = 0.5 * m * v²,
where m is the mass of the object and v is the velocity.
In this case, we know the mass of the family car (1237 kg) and the mechanical kinetic energy of the box car (50444 J). To calculate the speed of the family car, we can rearrange the formula to solve for v:
v = √(2*KE/m)

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

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.

A driver needs to make a delivery to an office that is 30 KM away. The driver has traveled for 45 minutes W. down the straight Road at 50 KM/H. Has the driver traveled far enough to reach the office? Support your response. 
Answers
Answer:
Yes, the driver traveled far enough to reach the office.
Explanation:
We can use the formula
[tex]v=\frac{x}{t}[/tex]
We are given
[tex]x=30[/tex] KM
[tex]t=45[/tex] min
[tex]v=50[/tex] KM/H
Lets convert minutes to hours.
To convert minutes to hours divide the speed by 60.
[tex]\frac{45}{60} =\frac{3}{4} =0.75[/tex]
Now we have
[tex]x=30[/tex] KM
[tex]t=0.75[/tex] H
[tex]v=50[/tex] KM/H
[tex]v=\frac{x}{t}[/tex]
Solve for x.
[tex]x=vt[/tex]
Lets substitute our values into the equation.
[tex]x=50*0.75[/tex]
[tex]x=37.5[/tex]
[tex]37.5 > 30[/tex] So the answer is yes; the driver traveled far enough to reach the office.
The driver has to travel 35 km to reach the office. The distance he covered with a speed of 50 km/h within 45 minutes or 0.75 hour is 37.5 km. Hence, he travelled enough to reach the office.
What is velocity?Velocity of a moving body is the measure of distance it covered within unit time. The velocity is a vector quantity and have a magnitude and direction. The units of velocity are km/h, m/s etc.
Velocity is the ratio of change in distance to the change in time. Hence, distance can be calculated by multiplying the velocity with time.
Given that, velocity of the driver = 50 Km/h
time taken = 45 minutes = 45/60 =0.75 hr
Therefore, the distance = 0.75 hr × 50 km/h = 37.5 km
The distance to the office is 30 km. Therefore, the driver traveled far enough to reach the office.

1 A police patrol Jeep is pursuing a car to a strafart level road. The Jeep and cas are mathe speeds 60kmlho and 72 krohr respectively. The patrol Jeep fires a bullot when car & 200 from it. If speed of bullet is 500mls what will be distance between twou eching when the bullet strikes the car?.
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.
In what sense is distance?Distance is the sum of an object's movements, regardless of direction. Distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.

The force F exerted on a ball during a collision with a wall is given as a function of time t by the equation F(t) = αt - βt 2 , where α = 400 N/s and β = 4000 N/s 2 . The ball first contacts the wall at t = 0, and the collision lasts for 0.10 s. What is the magnitude of the change in momentum of the ball?
a. 0
b. 0.67 kg m/s
c. 3.33 kg m/s
d. 3.60 kg m/s
e. The change in momentum of the ball cannot be determined without knowing the mass of the ball
Answers
The magnitude of the change in the momentum of the ball during the collision is 0 kgm/s. Correct option (a)
The given parameters:
Applied force, F(t) = αt - βt²
α = 400 N/s
β = 4000 N/s²
Duration of the collision, t = 0.1 s
The magnitude of the change in the momentum of the ball during the collision is calculated as follows;
change in momentum = impulse
ΔP = Ft
ΔP = (αt - βt²)t
ΔP = αt² - βt³
ΔP = 400t² - 4000t³
∆P=400*(0.1)^2 -4000*(0.1)^3 = 4-4 =0.
∆P= 0. kg m/s
Thus, the magnitude of the change in the momentum of the ball during the collision is 0 kgm/s.

If the springy part of the fern were attached to one seed and the stem, then when the --------- energy of a springy part is converted to ------- energy, some of the ----------energy would be on the stem.
In fact, if the stem has very little mass, then it would move a greater distance than the seed and according to -------------, more work would be done on the -------------
than on the ------------------.
If there are two seeds, then each will leave with the same ---------------- energy and no energy is wasted on unwanted motion of the stem.

"If the springy part of the fern were attached to one seed and the stem, then when the elastic potential energy of a springy part is converted to kinetic energy, some of the kinetic energy would be on the stem. In fact, if the stem has very little mass, then it would move a greater distance than the seed and according to W = f delta x, more work would be done on the stem than the seed. If there are two seeds, then each will leave with the same kinetic energy and no energy is wasted on unwanted motion of the stem."
Kinetic energy is possessed by the bodies which are in movement.
Elastic potential energy is the kind of energy stored as a result of applying force to deform an elastic object.
