Fluid clutches are used on equipment that is subject to frequent stopping.

Fluid couplings are used in various equipment in which the rotational torque must be transferred smoothly and without shock from the motor to the driven machine.

They are characterized by high transmittable torque and power, quick response times, and a good damping effect.

It absorbs and smooths torsional vibrations from the driveshaft, resulting in a longer lifespan of the drive components.

Equipment that is subject to frequent stopping.

For equipment that is subject to frequent stopping, fluid clutches are commonly used.

This is due to the fact that fluid clutches may be started and stopped frequently without causing harm or wear to the machine.

For this reason, fluid clutches are commonly used in machinery that needs a smooth start and stop, which is important to avoid any harm to the machinery.

In addition, fluid clutches are also less likely to slip, making them ideal for continuous running machines.

A) Gravity.

Explanation:

Earth is stuck in orbit around the sun, because of the Sun's gravitational pull. In this scenario, the string represents gravity, keeping the Earth attracted towards the sun.

Hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day and good luck with your assignment :)

The student ties a string around a weight and swings the weight in a circle around her body. If the student represents the sun and the weight represents earth, the string will represent GRAVITY then.

In mechanics, gravity—also known as gravitation—is the constant force of attraction that pulls all things together. It has little impact on determining the intrinsic characteristics of common stuff because it is by far the weakest known force in nature.

In contrast, it governs the formations and evolution of stars, galaxies, and the entire cosmos by its extensive and ubiquitous action, which affects the trajectories of objects in the solar system and beyond the universe. All objects on Earth experience weight, or a gravitational pull that is proportionate to their mass and is imposed by the planet's mass.

As the student represents the sun and the weight represents earth, the string will represent GRAVITY then. Hence, option (A) is correct.

Energy implies as the object’s capability to perform work. It is something that cannot be created or destroyed but can only be transformed. An object loses its energy, when it performs work, whereas it gains energy when the work is performed on it. Energy is broadly classified as kinetic energy and potential energy. While kinetic energy is the energy which an object contains because of a particular motion.

On the other hand, potential energy is the stored energy, because of its state of rest. As both the two forms of energy are measured in joules, people get easily confused between these two.

Explanation:

For this exercise the two basketballs are linked by gravitational interaction, so we can use gravitational energy

               U = - G m₁m₂ / R

In this case the mass is equal and the initial distance is r₁ = 19 cm = 0.19 m

               U₁ = - G m² / r₁

let's calculate

              U₁ = - 6.67 10⁻¹¹ 0.55² / 0.19

              U₁ = - 10,619 10⁻¹¹ J

when its centers are separated it is at r₂ = 1.4 m

              U₂ = - 6.67 10⁻¹¹ 0.55² / 1.4

              U₂ = - 1.44 10-11 J

the energy between these two points is

          ΔU = U₂ - U₁

Since the object is being dropped out of the window, it has no initial velocity.

\(176.4=\dfrac{1}{2}(9.8)t^2 \\\\t^2=36 \\\\t=6\text{ seconds}\)

Hope this helps!

Answer:

6 seconds

Explanation:

The formula for free fall is:

h = 1/2gt^2

We know that the height is 176.4 meters. We also know that on Earth, gravity is 9.8 m/s^2.

h=176.4

g=9.8

Substitute these values into the formula.

176.4=1/2(9.8)*t^2

Multiply 9.8 and 1/2

176.4=4.9*t^2

t^2 and 4.9 are being multiplied. The opposite of multiplication is division. Divide both sides by 4.9

176.4/4.9=4.9*t^2/4.9

176.4/4.9=t^2

36=t^2

t is being squared. The opposite of squared is the square root. Take the square root of both sides.

√36=√t^2

√36=t

6=t

t=6 seconds

It will take 6 seconds for the object to fall 176.4 meters.

The question is to calculate the time of flight of a projectile of a plane on surface of Mars.

The projectile is an object which is launched at angle θ with the horizontal.

The projectile is launched with an initial velocity "u"

The path/trajectory of projectile is a parabola.

The maximum horizontal distance between the point of launching and the point of landing is defined as the range of projectile 'R'.

The maximum time taken by the projectile to be in air or to travel the complete trajectory is defined as the time of flight 'T'.

Both the time of flight and the range depend on the initial velocity and the angle of projection.

Also the two parameters depend on acceleration due to gravity 'g'.

It is mentioned that projectile has same maximum horizontal distance on the earth and Mars.

We have to calculate the time of flight on Mars.

The formula of time of flight T = 2 u sinθ / g

On the earth, g = 9.8 m/s²

The value of acceleration due to gravity on the surface of Mars =

1/3* acceleration due to gravity on the Earth.

Let g' is equal to acceleration due to gravity on Mars.

Then, g = g/3

The time of flight of projectile on the surface of mars T' = 2u sinθ/g

T' = 2u sinθ / (g/3)

T' = (2u sinθ*3)/g

T' = 6u sinθ / g

Therefore, the time of flight of projectile on mars is 6u sinθ / g.

Explanation:

not really sure of an explanation, but maybe try looking up for "What type of star ends up as a blackhole?" should help

Answer:

43.3 m/s.

Explanation:

Assuming the potential energy is due to the gravitational potential energy, we can use the conservation of energy to find the kinetic energy:

Total energy = Potential energy + Kinetic energy

Kinetic energy = Total energy - Potential energy

Kinetic energy = 300 J - 40 J = 260 J

However, we need to know the mass of the object to convert the kinetic energy to velocity. We can use the potential energy to find the mass:

Potential energy = mgh

40 J = m(9.81 m/s^2)(300 m)

m = 0.137 kg

Now we can use the kinetic energy to find the velocity:

Kinetic energy = (1/2)mv^2

260 J = (1/2)(0.137 kg)v^2

v^2 = (2*260 J) / 0.137 kg

v = 43.3 m/s (rounded to one decimal place)

Therefore, the kinetic energy is 260 J and the velocity of the object when it reaches the ground is 43.3 m/s.

The total mechanical kinetic energy of the rider and motorcycle is  121500 Joule.

Mechanical energy, also known as kinetic energy or potential energy, is the energy that an object possesses when it is in motion or the energy that an object stores due to its location. Renewable energy is also fueled by mechanical energy. In order to efficiently produce electricity or convert energy, many sources of renewable energy depend on mechanical energy.

Given parameters:

Mass of the person: m = 70 kg.

Mass of the motorcycle: M = 200 kg.

Speed of the motorcycle: v = 30 m/s.

Total mass of the person and the motorcycle = m + M = 70 kg + 200 kg = 270 kg.

Hence, total mechanical kinetic energy = 1/2 × total mass × speed²

= 1/2 × 270 × 30² Joule

The gravitational force between two objects depends on two factors: their masses and the distance between them. According to the universal law of gravitation, the force of attraction between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Since the mass of the Sun is much greater than that of Mercury or Jupiter, and it is at the center of the solar system, it exerts the greatest gravitational force on the other objects in the solar system. Therefore, option B, the Sun, has the greatest gravitational force among the given options.

(A) The digestive sac of a jellyfish has one opening. the jellyfish's digestive sac has a single opening that serves for both intake and excretion purposes, allowing the organism to capture and consume prey while also eliminating waste materials through the same opening.

The digestive system of a jellyfish consists of a gastrovascular cavity, which serves as both a digestive and circulatory system. This cavity is a sac-like structure with a single opening, known as the mouth or gastrovascular opening.

The jellyfish captures its prey using its tentacles, which are armed with specialized cells called cnidocytes that deliver venomous stings. Once the prey is immobilized, the jellyfish uses its mouth to engulf it into the gastrovascular cavity.

The food is then broken down and digested within the sac, and the nutrients are absorbed directly into the jellyfish's cells. Waste materials are expelled back out through the same opening.
