It's crucial to inspect the brake drums as part of your walk-around examination before setting off on a journey. If any brake drum has a crack that is more than half the breadth of the friction region.

Overheating and undercooling of the brake pedal during operation might result in cracked drums.

Drums with cracks need to be changed right away. Blue ground -High temperatures, braking imbalance, abrupt stops, dragging brakes, or glazed brake pads can all result in blue drums. If no cracks have appeared, blue drums can still be utilized.

If three subintervals of equal length are used to do midpoint Riemann sum approximation of ∫f(x)dx from 3 to 6, then width of each subinterval is  1.

To find the midpoint Riemann sum, you first need to divide the interval of integration (from 3 to 6) into three subintervals of equal length. You can choose subintervals of equal length manually by dividing the interval of integration into smaller parts. If we let the width of each subinterval be x, then the length of the interval is 6-3 = 3 and the length of each subinterval, x is 3/3 = 1.

Then, you need to find the midpoint of each subinterval by adding the left and right endpoint of each subinterval and dividing by 2.

For example, the first subinterval is from 3 to 4, so the midpoint is (3+4)/2 = 3.5

the second subinterval is from 4 to 5, so the midpoint is (4+5)/2 = 4.5

and the third subinterval is from 5 to 6, so the midpoint is (5+6)/2 = 5.5

To approximate the area under the curve of f(x) for each subinterval, you can use the value of f(x) at the midpoint of each subinterval and multiply it by the width of the subinterval.

Convection and conduction are two ways that the Earth's heat is released.

The complex impedance of the 100 mH inductance when a voltage vL(t) = 10cos(2000πt) is applied to it is: j200Ω.

What is inductance?

Inductance is a property of an electrical component that describes the ability of the component to store energy in a magnetic field when electric current passes through it.

Inductance is measured in units of henrys (H). When current flows through a component with inductance, it creates a magnetic field around the component that resists changes to the current. This resistance to changes in current is called inductive reactance and is measured in units of ohms.

The complex impedance of an inductor is given by Z = jωL, where ω is the angular frequency and L is the inductance.
Therefore, the complex impedance of the 100 mH inductance when a voltage vL(t) = 10cos(2000πt) is applied to it is:
Z = j(2000π) (100 x 10-3) = j(2π) (100 x 10-3) = j200Ω

The magnitude of the gravitational field of the planet depends on its mass and distance from the object being affected by it.

What is Gravitational field?

Gravitational field is a region of space where a mass or object experiences a force of gravity. It is caused by the presence of a massive object, such as a planet or star, which exerts a gravitational pull on other objects within its vicinity. The strength of the gravitational field is determined by the mass of the object and its distance from other objects.

The gravitational field of the planet at Point P can be calculated by using the equation,

g = G*M/r2

where G is the gravitational constant (6.67 x 10-11 Nm2/kg2), M is the mass of the planet (4 x 1026 kg), and r is the distance from the center of the planet to Point P (53,000 km).

Plugging in the values,

g = (6.67 x 10-11 Nm2/kg2) x (4 x 1026 kg) / (53,000 km)2

g = (6.67 x 10-11 Nm2/kg2) x (4 x 1026 kg) / (2.8409 x 1012 m2)

g = (6.67 x 10-11 Nm2/kg2) x (14.1636 x 1015 kg)

g = 9.5 x 10-5 N/kg

Therefore, the magnitude of the gravitational field of the planet at Point P is 9.50 x 10-5 N/kg.

Newton's principles of motion and the universal law of gravitation can be used to derive Kepler's third law. Make the centripetal force equal to the force of gravity. The following expression, which may also be written as P2=42a3GM, can be obtained by inserting an expression for the planet's velocity: GMr=4r2P2. Thus, option B is correct.

Newton demonstrated that the force that causes something to fall toward the ground, like an apple, is the same force that causes the moon to orbit the Earth. The Sun, as well as any other star and its satellites, are affected by this universal force.

Newtonian physics and Kepler's laws serve as the foundation for planetary motion and orbital laws. Because these fundamental rules govern everything in the cosmos, they also govern how planets and artificial satellites move.

Therefore, If two things experience the same acceleration when the same force is applied to them, then they have the same inertial mass. Newton's second law makes use of the same mass.

Gestalt principles refer to a set of laws in psychology that describe how people perceive visual information. The four principles you mentioned are:

Proximity: Objects that are close to each other are perceived as being related to each other.

Similarity: Objects that are similar in appearance are perceived as being related to each other.

Continuity: People tend to perceive lines and shapes as continuing in the same direction, even if they are interrupted.

Closure: People tend to perceive incomplete shapes as complete, such as seeing a full circle when presented with a set of dots arranged in a circular pattern.

Gestalt theory reinforces the fact the whole of anything is greater than its parts. That is, the attributes of the whole are not deducible from analysis of the parts in isolation. The word Gestalt is utilized in modern German to imply the way a thing has been “placed,” or “put together.” There is no exact equivalent in English.

Harrison is incorrect because particles can force each other to vibrate more easily in elastic materials where particles are closer together. So, option A.

Vibration is a periodic back-and-forth motion of the particles in an elastic body or medium.

Here,

Vibrations occurs when practically any physical system is moved out of its equilibrium condition and is left to react to forces that work to bring it back into equilibrium.

A periodic shift in time is referred to as a vibration. A wave is a regular oscillation in both space and time. The waves propagate from one point to another in a medium.

Most waves travel through different media, and this affects how fast they move.

In general, waves go through solids the quickest and gases the slowest. The reason for this is that while particles in a gas are farthest to one another, those in a solid are closer to one another.

The piston's position, velocity, and acceleration at t = 1.15 s are :

Position: 3.45 m

Velocity: 3 m/s

Acceleration: 0 m/s^2

To calculate the piston's position, velocity, and acceleration at t = 1.15 s, we need to know the angular position, velocity, and acceleration of the wheel.

The angular position of the wheel at t = 1.15 s is given by

θ = ωt + [tex]A_{0}[/tex]

where ω is the angular frequency, t is the time, and [tex]A_{0}[/tex] is the initial angular position.

Since the angular frequency is given as 12 rad/s and the initial angular position is 0, the angular position of the wheel at t = 1.15 s is

θ = 12 x 1.15 = 13.8 radians

The piston's position is given by

r = Rθ

where R is the radius of the wheel.

Substituting the value of R and θ,

r = 0.25 x 13.8 = 3.45 m

The velocity of the piston is given by

v = r' = Rθ' = Rω

Substituting the values

v = Rω = 0.25 x 12 = 3 m/s

Acceleration of the piston is given by

a = v' = Rθ'' = Rω' = R(ω^2)θ

As the angular frequency is constant, the angular acceleration is 0 so the linear acceleration is also 0.

Note: Linear acceleration is not equal to the derivative of linear velocity, it is equal to the derivative of velocity with respect to time, which is zero in this case.
