Answers

Answer 1

The type of faucet that uses a rotating cylinder to control water temperature and the rate of water flow by using a balancing piston is called a thermostatic mixing valve.

A thermostatic mixing valve is a mechanical device designed to provide precise control over the temperature of the water coming out of the faucet. It is commonly used in showers, baths, and other plumbing fixtures where maintaining a consistent and comfortable water temperature is important.

The valve consists of a central rotating cylinder that contains both hot and cold water inlets. As you turn the handle or lever of the faucet, the cylinder rotates, allowing you to adjust the proportion of hot and cold water that mixes together.

Inside the cylinder, there is a balancing piston that is sensitive to changes in water temperature and pressure. This piston helps to maintain a consistent temperature by adjusting the flow rates of hot and cold water.

When you set the desired temperature, the piston moves to balance the flow of hot and cold water, ensuring that the mixed water remains at a constant temperature regardless of any fluctuations in the supply temperature or pressure.

3. Someone at the third-floor window (12.0 m above the ground) hurls a ball downward at an angle of 45 degrees with a speed of 25 m/s. How fast will the ball be traveling when it strikes the sidewalk below?

Answers

The ball will be traveling at a speed of approximately 18.9 m/s when it strikes the sidewalk below.

What is Speed?

It is defined as the distance traveled per unit of time, usually expressed in units such as meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph).

The horizontal component of the velocity remains constant throughout the motion, and it is given by:

Vx = Vcosθ

where V is the initial velocity of the ball and θ is the angle of projection. In this case, V = 25 m/s and θ = 45°, so:

Vx = 25*cos(45°) = 17.68 m/s

The vertical component of the velocity changes due to the acceleration due to gravity (g = 9.8 m/s^2). At the highest point, the vertical component of the velocity becomes zero, and the ball starts falling downwards. The final velocity (v) of the ball just before hitting the ground can be calculated using the following equation:

v^2 = u^2 + 2as

where u is the initial velocity in the vertical direction, a is the acceleration due to gravity, s is the distance traveled in the vertical direction, and v is the final velocity.

Initially, the ball is at a height of 12.0 m above the ground, so s = 12.0 m. The initial velocity in the vertical direction (Vy) is given by:

Vy = Vsinθ

where V is the initial velocity of the ball and θ is the angle of projection. In this case, V = 25 m/s and θ = 45°, so:

Vy = 25*sin(45°) = 17.68 m/s

When the ball hits the ground, its final velocity in the vertical direction is zero. Therefore, we can write:

v^2 = u^2 + 2as

0 = (17.68)^2 + 2*(-9.8)*12.0 - final velocity^2

final velocity = 18.9 m/s (approx)

Therefore, the ball will be traveling at a speed of approximately 18.9 m/s when it strikes the sidewalk below.

bike is traveling with a velocity of 22 m/s and has a mass of 25 kg. How much kinetic
energy does the bike have? PSc. 3.1.2

Answers

Answer: 12,100 Joules of Kinetic Energy

Explanation:

Kinetic energy is a measure of how much energy something has because it's moving. To calculate the kinetic energy of a bike, you need to know how heavy it is and how fast it's going. We use a formula that looks like this:

(1/2) x the weight of the bike (in kilograms) x the speed of the bike (in meters per second) x the speed of the bike (in meters per second)

So if we have a bike that weighs 25 kilograms and is going 22 meters per second, we can plug those numbers into the formula like this:

(1/2) x 25 x 22 x 22

And we find out that the bike has 12,100 Joules of kinetic energy.

How are velocity and force similar?

Answers

Answer: Force

In physical science, a force is something that acts on an object by pushing or pulling it. If the force is strong enough, it changes the position or shape of the object. Forces such as friction, air resistance and simple physical contact touch the object directly, while forces like gravity, magnetism and electrostatics act on the object from a distance. Force is a vector quantity, meaning you can measure both its strength and its direction. The formula to find the measure of a force is force = mass times acceleration, written as f = ma.

Velocity

The faster something is moving, the higher its velocity.

When an object is moving, one way to measure how fast it is moving is by finding its velocity, which is the rate at which it is changing position. Like force, velocity is a vector quantity, so it includes direction. To find the average velocity of an object, divide the change in its position by the time the movement took, and state its direction. For example, if a car is driving north and in one hour's time it travels 30 miles, its velocity is 30 miles per hour, north.

what physical characteristics of the bedrock are responsible for the oldest rock remaining at the highest elevevation?

Answers

Answer:

The oldest rock being found at the highest elevation is primarily due to the geological process of mountain building or tectonic uplift.

During mountain building, tectonic plates collide, causing the land to uplift and fold. This process can bring older rock layers closer to the surface, or even expose them at the highest elevations. As the land is pushed upward, erosion occurs, causing the overlying layers to be removed, and the older rock layers to be exposed at the surface.

The physical characteristics of the bedrock that enable it to remain at the highest elevation during this process are its strength and resistance to erosion. The older rock layers are typically made up of harder and more resistant rock types, such as granite or metamorphic rocks, that are more resistant to weathering and erosion compared to younger sedimentary rocks.

As a result, the older and more resistant rock layers are able to withstand the effects of erosion and remain at the highest elevation. This is why the highest peaks of mountain ranges, such as the Himalayas or the Rocky Mountains, often consist of the oldest rock formations.

A uniform flexible chain of given length is suspended at given points (x,y) and (39, 42). Find the curve in which it hangs. Hint: It will hang so that its center of gravity is as low as possible.

Answers

The curve in which the uniform flexible chain hangs is given by: f(x) = (39/2) × (cosh(k × x) - 1) + (42-c1) × sinh(k × x)/c2 where k, c1, and c2 are determined by the length of the chain and the positions of the suspension points.

To find the curve in which the uniform flexible chain hangs, we need to minimize its potential energy by ensuring its center of gravity is as low as possible. We can start by dividing the chain into small segments of length dx and considering the gravitational potential energy of each segment.

Let the curve be described by the function y = f(x), where f(x) is the height of the chain at position x. The mass of each small segment of length dx is proportional to the square root of 1 + (dy/dx)^2, and its center of gravity is located at a height of f(x) + (dy/dx)×(dx/2).

Thus, the gravitational potential energy of the chain is given by:

U = ∫(y=0 to y=f(39))∫(x=0 to x=39) g×y×(1 + (dy/dx)²)^(1/2) dx dy

where g is the acceleration due to gravity. To find the curve f(x) that minimizes U, we need to solve the Euler-Lagrange equation:

d/dx (dL/dy') - dL/dy = 0

where L is the Lagrangian, defined as:

L = (1 + (dy/dx)²)^(1/2)

Solving the Euler-Lagrange equation for f(x), we get:

f(x) = c1×exp(k×x) + c2×exp(-k×x)

where k is a constant determined by the length of the chain and the positions of the suspension points, and c1 and c2 are constants determined by the initial conditions (i.e. the heights of the suspension points).

To find k and the constants c1 and c2, we can use the fact that the length of the chain is constant:

∫(x=0 to x=39) (1 + (dy/dx)^2)^(1/2) dx = constant

Substituting f(x) into this equation and solving for k and the constants, we get:

k = (1/39)×acosh((42-c1)/c2)

c1 = (39/2)×(cosh(k×39) - 1) + 21

c2 = (42-c1)/sinh(k×39)

Therefore, the curve in which the uniform flexible chain hangs is given by:

f(x) = (39/2)×(cosh(k×x) - 1) + (42-c1)×sinh(k×x)/c2

where k, c1, and c2 are determined by the length of the chain and the positions of the suspension points.

A spring is stretched 0.15 m and the force was 1500 N. What is the spring constant?

Answers

Use the formula f=kx where f is force, k is spring constant, and x is extension.

1500=k* 0.15
K= 1500/0.15 = 10000

The spring constant for a spring is stretched 0.15 m and the force was 1500 N is 10000.

What is spring constant?

The spring constant, k, is a measure of the spring's stiffness. It varies depending on the spring and material. The greater the spring constant, the stiffer the spring and more difficult to stretch.

The letter k symbolizes the "spring constant," which is a number that tells us how "stiff" a spring is.

If k is large, it means that more force is required to stretch it a certain length than would be required to stretch a less stiff spring the same length.

We know that,

F = k(x)

Where k is the spring constant.

Here, it is given that:

F = 1500N

x = 0.15m

So,

1500 = k (0.15)

k (0.15) = 1500

k = 1500/0.15

k = 150000/15

k = 10000

Thus, the value of spring constant is 10000.

The plane of the loop is initially at an angle of 59.914o to the direction of the magnetic field. What is the magnitude of the torque on the loop ?

Answers

ANSWER:

10.58 Nm

STEP-BY-STEP EXPLANATION:

Given:

Area (A) = 2.936 m²

Current (i) = 6.488 A

Magnetic field (B) = 1.108 T

Angle (θ)= 59.914°

To calculate the torque we must resort to the following formula:

\(\begin{gathered} \tau=MB\sin\alpha \\ \\ \alpha=90\degree-\theta=90-59.914\degree \\ \\ \alpha=30.086\degree \end{gathered}\)

We need to know the magnetic moment, as follows:

\(\begin{gathered} M=NIA \\ \\ M=1\cdot6.488\cdot2.936 \\ \\ M=19.05\text{ A}\cdot m^2 \end{gathered}\)

In this way we can calculate the torque:

\(\begin{gathered} \tau=19.05\cdot1.108\cdot\sin(30.086\degree) \\ \\ \tau=10.58\text{ Nm} \end{gathered}\)

Therefore, the magnitude of the torque on the loop is 10.58 Nm

Answers

Answer:

X - component = v2 = 0.650 m/s

Y - component = v2 = 0.447 m/s

Explanation:

Given that :

Conservation of momentum

m1u1 + m2u2 = m1v1 + m2v2

m = mass of pool ball ; u = initial velocity ; v = final velocity

Since the masses are identical

x - component

u1 + u2 = v1 + v2

u1 = 1.33 m/s

u2 = 0

Final speed of first ball = 0.814 m/s at an angle of 33.3° ;

v1 = 0.814*cos33.3 = 0.814 * 0.8358073 = 0.6803471 m/s

v2x = u1x + u2x - v1

v2x = 1.33 + 0 - 0.6803471

v2x = 0.6496529 m/s

v2x = 0.650 m/s

Y - component :

v1sinθ= 0.814*sin33.3 ; 0.814 * 0.5490228 = 0.4469045 m/s

v2y = 0.447 m/s

The object has a tangential acceleration only if the disk has an angular acceleration.

Answers

The statement is true. The tangential acceleration of an object on a rotating disk is directly related to the angular acceleration of the disk.

When the disk undergoes angular acceleration, there is a change in the tangential velocity of any object on the disk. This change in velocity results in a tangential acceleration. However, if the disk is not undergoing angular acceleration, there will be no change in the tangential velocity of the object, and therefore no tangential acceleration.

Angular acceleration is the rate at which the angular velocity of a rotating object changes over time. It is a measure of how quickly an object is changing its rotational speed. Mathematically, angular acceleration is defined as the time derivative of angular velocity:

α = dω/dt

where:

α is the angular acceleration (measured in radians per second squared)ω is the angular velocity (measured in radians per second)t is time (measured in seconds)
