Vehicles equipped with disc brakes incorporate a mechanically operated drum-style parking brake in the center of the rear disc brake rotors, commonly called a top hat parking brake.
What is top hat parking brake?
The top hat drum style of parking brake system is called the top hat rotors because of how big the middle part is compared to regular rotors.
In this type of parking brake system, the vehicle is equipped with disc brakes which incorporate a mechanically operated drum-style parking brake in the center of the rear disc brake rotors.

Is cereal soup? Why or why not? Pls HELP ASAP
Answer:
yes
Explanation:
by definition, yes. soup is defined as "a liquid dish, typically made by boiling meat, fish, or vegetables, etc., in stock or water.", so a liquid dish prepared by boiling and extracting flavor. so technically, a bowl of cereal would be a wheat-milk soup.

A block is at rest on a frictionless ramp that is elevated 22.0 degrees above the horizontal.
a)Determine the acceleration of the block as it slides down the ramp.
Answer:
3.67 m/s²
Explanation:
Draw a free body diagram. There are two forces on the object:
Weight force mg pulling straight down,
and normal force N pushing perpendicular to the plane.
Sum the forces in the parallel direction.
∑F = ma
mg sin θ = ma
a = g sin θ
a = (9.8 m/s²) (sin 22.0°)
a = 3.67 m/s²
In a science lab, Cash mixes two clear liquids together in a beaker. Bubbles are produced, and a white solid forms and settles to the bottom. He plans to heat the beaker over low heat and make more observations.Which statement is most likely correct? A physical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids. A physical change occurred, so even if Cash heats it, the white solid will remain. A chemical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids. A chemical change occurred, so even if Cash heats it, the white solid will remain.
Answer:
A chemical change occurred, so even if Cash heats it, the white solid will remain
Explanation:
There are two types of changes that occur in Chemistry viz; physical change and chemical change. Physical changes are those changes do not involve any change in the chemical composition of the substances involved while a chemical change involves a change in chemical composition.
In a chemical change, there are characteristics signs such as formation of gaseous bubbles, solid precipitates etc. as the information in this question depicts. According to this question, Cash mixes two clear liquids together which results in the formation of bubbles and a white solid that settles at the bottom. Hence, THIS REPRESENTS A CHEMICAL CHANGE
Most chemical changes are usually irreversible i.e. they don't return to their original form. Hence, even if Cash heats it, the white solid will remain.
Answer:
A chemical change occurred, so even if Cash heats it, the white solid will remain

Calculate the number of moles in 44 g of iron sulfide.
Relative atomic masses
(4): Fe = 56, S = 32
Answer:
2 moles
Explanation:
please mark me as brainlest
The mass of one mole of iron sulphide is 88 g. Then the number of moles in 44 g is 0.5 moles.
What is one mole ?One mole of a substance is its amount which contains 6.022 × 10²³ atoms. This number is called Avogadro number. One mole of every element contains Avogadro number of atoms.
Similarly one mole of every compound contains Avogadro number of molecules. The mass of one mole of a compound is called its molar mass.
Atomic mass of Fe = 56 g/mol
atomic mass o S = 32 g/mol
molar mass of FeS = 56 + 32 = 88 g/mol
Mass of one mole of iron sulphide (FeS) is 88 g. Hence number of moles in 44 g is :
no.of moles = given weight/molar mass
= 44 g /88 g/mol = 0.5 mol
Therefore, the number of moles of FeS in 44 g is 0.5.

A box falls off of a tailgate and slides along the street for a distance of 62.5 m. Friction slows the box at –5.0 m/s2. At what speed was the truck traveling when the box fell?
Answer:
25 m/s
Explanation:
This question can be solved using equation of motion
[tex]v^2 = u^2 + 2as[/tex]
where
v is the final velocity
u is the initial velocity
s is the distance covered while moving from initial to final velocity
a is the acceleration
_____________________________________________
Given
box moved for distance of 62.5 m
Friction slows the box at –5.0 m/s2----> this statement means that there is deceleration , speed of truck decreases by 5 m/s in every second until the box comes to rest. Friction causes this deceleration.
thus in this problem
a = -5.0 m/s2
V = 0 as body came to rest due to friction deceleration
u the initial velocity we have to find
the initial velocity of box will be the same as speed of truck, as the box was in the truck and hence box will pick the speed of truck.
so if we find speed of box, we will be able get sped of truck as well.
using equation of motion
[tex]v^2 = u^2 + 2as\\0^2 = u^2 + 2*-5* 62.5\\0 = u^2 - 625\\u^2 = 625\\\sqrt{u^2} = \sqrt{625} \\u = 25[/tex]
Thus, initial speed with the truck was travelling was 25 m/s.

The bicep muscle has an attachment point at the shoulder and one in the upper forearm. Look at these images of the bones of the arm. Imagine that the point of the arrow is where the force of the biceps muscle is applied to the bone. 4 images of the bones of the arm are shown. In image A, the bicep pulls the forearm upwards. In image B, the forearm pushes the bicep upwards. In image c, the forearm pulls to the right. In image D, the forearm pushes to the left. Which image would result in the biceps muscle contracting and the forearm being lifted? A B C D.
Option A is correct. The biceps is the muscle that runs down the front of the upper arm. The biceps consists of a single muscle with a "short head" and a "long head'.
What is a bicep muscle?
The biceps is the muscle that runs down the front of the upper arm. The biceps consists of a single muscle with a "short head" and a "long head."
Tough connective fibers called tendons link the biceps to the arm bones. Because the insertion of the bicep muscle is in the forearm, when it contracts, it raises the forearm.
Hence Option A is correct.

An airplane accelerates with a constant rate of 3.0 m/s2 starting at a velocity of 21 m/s. If the distance traveled during this acceleration was 535 m, what is the final velocity?
Answer:
60.42 m/s.
Explanation:
This problem can be solved using equation of motion
[tex]V^2 = u^2 + 2as[/tex]
where v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance moved by the body to reach final velocity v from initial velocity u.
___________________________________________________
given
u = 21m/s
a = 3.0 m/s2
s = 535 m
v, the final velocity we have to find
using the equation of motion
[tex]V^2 = u^2 + 2as\\V^2 = 21^2 + 2*3*535\\V^2 = 441 + 3210 = 3651\\\sqrt{v^2} = \sqrt{3651} \\v = 60.42[/tex]
Thus, the final velocity of airplane is 60.42 m/s.
The final velocity is 60.42 m/s
The parameters given in the question are;
initial velocity(u)= 21 m/s
acceleration(a)= 3.0 m/s²
distance(s)= 535 meters
final velocity(v)= ?
The final velocity can be calculated as follows
v²= u² +2as
v²= 21² + 2(3)(535)
v²= 441 + 3210
v²= 3651
v= √3651
v= 60.42
Hence the final velocity is 60.42 m/s

a car is moving at 30.0 km/h when it accelerates at 2.0 m/s for 3.6 s. what is the car final speed?
Answer:
wrong question
Explanation:
unit of acceleration is written in m/s which is wrong
The final velocity of the car which is moving with the initial velocity of 30km/h is 15.53m/s.
What is Acceleration?Acceleration of an object is the rate of change in the velocity of an object. It depends upon the initial and final velocity of an object. It is a vector quantity because it has both magnitude and direction. The SI unit of acceleration is meter per second square.
a = (v-u)/ t
v = u + at
u = 30 × 1000/ 3600 = 8.33m/s
a = 2.0m/s²
t = 3.6 seconds
v = u + at
v = 8.33 + 2.0 × 3.6
v = 8.33 + 7.2
v = 15.53m/s
Therefore, the final velocity of the car is 15.53m/s.
