what is a roller support​

Answer:

1. Fluids can be both liquids and gases.

2. Hydraulics involve pushing.

3. Pneumatics involve pulling.

4. Water can be used in hydraulic systems to lift and lower a car using a hydraulic lift. The water is pumped into a hydraulic cylinder which then pushes a piston up to lift the car.

5. Increased pressure in the pneumatic tube makes the chair go up.

6. Holding down the pump lets air out, which decreases pressure, making the chair go down.

7. When you push all the water from a little syringe into a big syringe, the big syringe does not pop out the same distance as the little syringe was pushed in. This is because the pressure under the larger piston is less than the pressure under the smaller piston due to the difference in the size of the pistons.

8. Yes, the car should move up as far as the thinner "small force" moves down according to Pascal's Law, which states that pressure applied to a confined fluid is transmitted equally in all directions and acts with equal force on equal areas.

9. The pressure under piston 1 is equal to the pressure under piston 2 according to Pascal's Law.

Answer:

Inversion and the conservation of ambiguity are two geometric transformations that can be used to analyze and study geometric figures. While they have some similarities, they also have some important differences.

Inversion is a geometric transformation that involves inverting a figure in a circle or a sphere with respect to a center. This transformation maps every point inside the circle to a point outside the circle, and vice versa. Inversion is a conformal transformation, which means that it preserves angles between lines and circles. Inversion is useful for studying circles and angles, and it can be used to prove many theorems in Euclidean geometry.

On the other hand, the conservation of ambiguity is a geometric property that states that if a figure can be transformed into another figure by a certain transformation, then the transformation can be reversed to transform the second figure back into the first one. This property is important in topology, which is the study of the properties of geometric figures that are preserved under continuous transformations.

One similarity between inversion and the conservation of ambiguity is that both are transformations that preserve certain properties of geometric figures. Inversion preserves angles, while the conservation of ambiguity preserves the topology of a figure. Another similarity is that both can be used to prove theorems and to analyze geometric figures.

However, there are also some important differences between inversion and the conservation of ambiguity. Inversion is a specific geometric transformation that involves inverting a figure in a circle or a sphere. In contrast, the conservation of ambiguity is a more general property that applies to any transformation that preserves the topology of a figure. Additionally, inversion is a transformation that is specific to Euclidean geometry, while the conservation of ambiguity is a property that applies to any type of geometry.

In summary, inversion and the conservation of ambiguity are two important concepts in geometry, but they have different applications and properties. Inversion is a specific transformation that is useful for studying angles and circles, while the conservation of ambiguity is a general property that applies to any transformation that preserves the topology of a figure

The best description of the function is the one in option B, the central line represents average variation

In a control chart, the central line represents the process average or mean, and it is used to monitor the variation of a process over time.

The upper and lower control limits are typically set at a certain number of standard deviations from the mean and are used to identify when the process is experiencing unusual or out-of-control variation.

The central line itself does not indicate the upper or lower control limits or serve as a differentiator between known and unknown variation sources.

This the correct option is B.

The rocket mass that would make a rocket with a thrust of 130,000 N reach 220 Km would be 2,954.55 kg.

To solve this problem, we need to apply the basic equations of motion. We will assume that the only force acting on the rocket is the thrust force, and we will ignore the effects of air resistance and gravity.

Calculate acceleration (a) using thrust (F) and mass (m):

Given the thrust F = 130,000 N, we have:

a = 130,000 / m

Apply the equation of motion:

Given y = 220,000 m (220 km), y0 = 0 m (initial position), v0 = 0 m/s (initial velocity), and t = 100 s, we can write the equation as:

220,000 = 0 + 0 * 100 + 0.5 * (130,000 / m) * (100)^2

Solve for mass (m):

220,000 = 0.5 * (130,000 / m) * 10,000

440,000 = 130,000 * 10,000 / m

m = 130,000 * 10,000 / 440,000

m = 2, 954.55 kg

In conclusion, the mass of the rocket that makes it reach 220 km with a thrust of 130,000 N and a thrust time of 100 s is approximately 2, 954.55 kg.

Explanation:

Once a vehicle's factory warranty expires, you're responsible for the cost of any repairs the car may need, even if a defect or poor workmanship caused the failure. You can protect yourself from the cost of repairs with an extended warranty or service contract, though the added coverage can come with a high price tag.

If Pascal's law is true, it means that the pressure in the chamber under piston 1 is equal to the pressure under piston 2.

If Pascal's law is true, it means that the pressure in the chamber under piston 1 is equal to the pressure under piston 2. When a force is applied to the smaller piston 1, it creates pressure in the fluid, which then gets transmitted uniformly throughout the fluid and to the larger piston 2.

As a result, the pressure under piston 2 increases, allowing it to exert a greater force on the object being lifted. This is the principle behind hydraulic press systems, which use Pascal's law to generate a large force with a relatively small input force.

The currents and resistances of the circuits are

Circuit 1

The resistors are in series

The total resistance of resistors in series can be calculated using the formula:

Rtotal = R1 + R2 + R3 + ...

So, we have

Rtotal = 2.2 + 1 + 1

Rtotal = 4.2KΩ

The current is calculated as

I = V/R

So, we have

I = 6V/4.2KΩ

I = 6V/4.2 * 1000 Ω

Evaluate

I = 0.00143 A

Circuit 2

The resistors are in parallel

The total resistance of resistors in parallel can be calculated using the formula:

1/Rtotal = 1/R1 + 1/R2 + 1/R3 + ...

So, we have

1/Rtotal = 1/1 + 1/2.2 + 1/3.3

Rtotal = 1.76KΩ

The current is calculated as

I = V/R

So, we have

I = 12V/1.76KΩ

I = 12V/1.76 * 1000 Ω

Evaluate

I = 0.0068 A

Circuit 3

The resistors are in parallel band in series

So, we have

R = 3.3 + 2.2

R = 5.5

Next, we have

Rtotal = 1/5.5 + 1/10

Rtotal = 0.28 KΩ

The current is calculated as

I = V/R

So, we have

I = 9V/0.28KΩ

Evaluate

I = 0.032 A

Circuit 4

The resistors are in parallel band in series

So, we have

R = 1/6.1 + 1/6.1

R = 2/6.1

Next, we have

Rtotal = 1 + 2/6.1

Rtotal = 1.33KΩ

The current is calculated as

I = V/R

So, we have

I = 9V/1.33KΩ

Note that where the above ocndition exists, as the demand for labor increases due to the increased order, the demand curve shifts to the right, indicating that Pk will be willing to hire more workers at a higher wage rate to meet the new demand for food preparation.

Assuming that the two workers can prepare food for 50 heads per day, it means they can prepare food for 250 heads in five days (50 heads/day x 5 days = 250 heads).

However, with the new order of preparing food for 200 heads, Pk will need to increase the demand for labor to meet the new demand. One way to show this on a graph is by using a labor demand curve, which illustrates the relationship between the quantity of labor demanded and the wage rate.
