Answer and Explanation:

a) The direction is shown in the cube diagram attached to this solution.

b) the angle between two planes (h₁, k₁, l₁) and (h₂, k₂, l₂) is given by the formula,

Cos Φ = (h₁h₂ + k₁k₂ + l₁)/√((h₁² + k₁² + l₁²)(h₂² + k₂² + l₂²))

For (111) and (112)

Cos Φ = (1.1 + 1.1 + 1.2)/√((1² + 1² + 1²)(1² + 1² + 2²))

Cos Φ = (1 + 1 + 2)/√((1+1+1)(1+1+4))

Cos Φ = 4/√(3×6)

Cos Φ = 4/√18

Φ = cos⁻¹ (4/√18) = 19.56°

c) equation 3.3 is missing from the question, I would be back to provide the answers to that as soon as the equation is provided!

Hope this Helps!!

In Shoreville, the last low tide was at 12:00 a.m. About what time will the next high tide occur
sergiy2304 [10]

Answer:

The next high tide will happen at 6 pm.

Explanation:

The rotation of the Earth and the translation movement of the Moon (ie the Moon's movement around the Earth), in addition to the gravitational force, contribute to the formation of the tides. The high tide will occur on the face of the Earth which is facing / facing the Moon; the low tide will occur on the faces that are forming approximately an angle of 90 ° with respect to the Moon.

There are usually two periods of high tide and two periods of low tide over a day. The interval between high tide and low tide is approximately 6 hours.

Besides the gravitational force exerted by the Moon, the tide is also influenced by the gravitational force that the Sun exerts on the Earth. The influence of the Sun is smaller due to its distance, but it can also be noticed depending on the phase of the Moon.

What does the duct calculator tell a technician about static pressure and airflow?
scoray [572]

Answer:

It displays the static pressure loss over a length of 100 feet for a specific duct size and airflow.

<h2>What is a ductulator?</h2>

People who work in the HVAC and construction industries use ductulators to size the ductwork in mechanical systems. It enables you to select the volumetric flow rate after selecting the static pressure you wish to keep in the duct. The ductulator offers you a wide range of rectangular duct diameters that will create this when you enter those criteria. It also displays the required diameter for a circular duct. The actual instrument is constructed of sturdy, thick paper, and it contains a rotating piece that lets you select the two settings I previously indicated.

A very large redwood tree is measured to be about 100 units tall. Which unit is the most appropriate to use? A millimeters B cen
Kruka [31]

Answer:

The most appropriate unit to use for a redwood is:

  • <u>C. meters</u>.

Explanation:

The largest tree in the world is called Hyperion and it is a  <em>Sequoia sempervirens</em>, that is to say, a redwood, which measures a little more than 115 meters, when knowing this data first hand, you can imagine that <u>the vast majority of trees are usually measured in meters since their size is usually one meter in ahead (although you should know that there are some shrub species that can measure only centimeters, but being a minority, the meter unit is usually used)</u>.
