Which graph best represents the relationship between KE and speed?

3. Gears are wheels with teeth that slot together. When one gear is turned the other one turns as well. If the gears are of different sizes, they can be used to increase the power of a turning force. The smaller wheel turns more quickly but with less force, while the bigger one turns more slowly with more force.

4. 4.10 gears are going to accelerate faster and decelerate faster on the lift. However, the trade-off is greater fuel consumption per mile driven and higher engine speed per given road speed. In basic terms, the 4.10 gears will feel quicker and 3.73 will feel faster.

Explanation:

To compare materials H and K, we need to determine the modulus of elasticity for each material. The modulus of elasticity is a measure of a material's stiffness, specifically the amount of stress required to produce a given amount of strain.

We can use the formula:

stress = force / area

strain = change in length / original length

modulus of elasticity = stress / strain

Let's start by calculating the stress on each wire:

For wire 1:

stress = force / area = (225 lb) / ((pi/4) * (3/8 in)^2) = 7,655 psi

For wire 2:

stress = force / area = (225 lb) / ((pi/4) * (3/16 in)^2) = 30,620 psi

Next, we can calculate the strain on each wire:

For wire 1:

strain = change in length / original length = 0.10 in / 480 in = 0.000208

For wire 2:

strain = change in length / original length = 0.25 in / 480 in = 0.000521

Finally, we can use the formula to calculate the modulus of elasticity for each material:

For material H:

modulus of elasticity = stress / strain = 7,655 psi / 0.000208 = 36,824,038 psi

For material K:

modulus of elasticity = stress / strain = 30,620 psi / 0.000521 = 58,745,334 psi

Therefore, material K has the greater modulus of elasticity and is the stiffer material.

Answer:

The diameter of the rod can be determined using the following formula:

Explanation:

d = sqrt(4L / (pi * E * delta))

where:

d = diameter of the rod

L = length of the rod = 35 ft

E = modulus of elasticity of the steel = 30,000,000 psi

delta = elongation of the rod = 0.266 in

First, we need to convert the length of the rod and elongation to inches to maintain consistency with the units of E:

L = 35 ft * 12 in/ft = 420 in

delta = 0.266 in

Substituting the given values into the formula:

d = sqrt(4 * 420 / (pi * 30,000,000 * 0.266))

d = 0.615 in (rounded to 0.01)

Therefore, the diameter of the steel rod is 0.62 inches (rounded to 0.01).

Explanation:

Wiring a doorbell button switch in the normally-open (NO) state is preferred because it is safer and more reliable than wiring it in the normally-closed (NC) state.

In a doorbell circuit, when the doorbell button is pressed, it completes the circuit and allows current to flow to the doorbell, causing it to ring. In the NC configuration, the button switch is always closed, and current flows through the circuit even when the button is not pressed. This can cause several problems, such as short circuits, overheating, and premature wear on the doorbell and other components in the circuit.

On the other hand, in the NO configuration, the button switch is open when it is not pressed, and no current flows through the circuit. When the button is pressed, it closes the circuit and allows current to flow, causing the doorbell to ring. This configuration is safer because it minimizes the risk of short circuits, overheating, and premature wear on the components in the circuit.

In addition to being safer, the NO configuration is also more reliable because it is less prone to false triggers. In the NC configuration, the button switch can be triggered by vibration, accidental contact, or other factors, causing the doorbell to ring unnecessarily. In the NO configuration, however, the button switch must be deliberately pressed to trigger the doorbell, making it less likely to ring accidentally.

Overall, wiring a doorbell button switch in the normally-open state is the preferred configuration for safety, reliability, and durability.

Answer:

Yes! I can Answer that!

Explanation:

C) Block the inlet of the valve.

A blocked drain on a pressure-reducing valve can prevent the valve from functioning correctly by blocking the drain line that is used to relieve excess pressure from the valve. As a result, the inlet of the valve can become blocked, causing the valve to malfunction and preventing it from reducing pressure. It is important to keep the drain line clear to ensure that the pressure-reducing valve works properly.

Note that if the  vanelli family is building a house and wants to save anywhere they can the choice that would be most expensive electric system for them to operate is a Heat Pump. (Option a)

A heat pump is a device tha tuses electricity to generate heat so that during winter and very cold period, the house is kept warm.

This is notably one of th most expensive devices to maintain in a home.

Hence it will be very expensive for the Vanelli familyto build a house that has many heat pumps. They can opt for solar powered heat pumpts instead.
