if you increase the pressure on a sprinkler nozzle from 46 psi to 66 psi, the new flow rate will be approximately 32.496 gallons per minute, assuming a flow rate coefficient (K) of 4.0.

Q = K * √(P)

where sqrt(P) is the square root of the pressure in psi.

Using this formula, we can calculate the new flow rate as follows:

New flow rate = 4.0 * √(66) = 4.0 * 8.124 = 32.496 gallons per minute (approx.)

Pressure is a physical quantity that describes the force exerted per unit area. It can be defined as the amount of force applied to a given area or surface. Pressure is typically measured in units of Pascals (Pa), which is equivalent to one Newton per square meter (N/m²).

Pressure can be exerted by any type of matter, including gases, liquids, and solids. For example, the pressure of the air around us is the result of the weight of the atmosphere pushing down on the surface of the Earth. In general, pressure increases with increasing depth in a fluid or with increasing force applied to a surface. It also varies with temperature and can be affected by the properties of the material being measured.

Answer:

D.Oxygen has five valence electrons

The chemical reactivity of an atom is determined by the number of electrons present in its outermost shell, also known as the valence electrons.

These electrons play a key role in determining the chemical properties of an atom, such as its reactivity and bonding behavior. An atom with a full or nearly full valence shell is less likely to engage in chemical reactions, while an atom with a partially filled valence shell is more reactive and readily participates in chemical reactions. Thus, the number of electrons in the valence shell is a critical factor in determining the chemical reactivity of an atom. Chemical reactivity refers to the ability of a substance to participate in chemical reactions and form new compounds. It is determined by various factors, including the arrangement of electrons in the outermost shell (valence electrons), the stability of the electronic configuration, and the energy required to break or form chemical bonds.

By Newton's second law, the net force acting on the block in the vertical direction is

∑ F [ver] = n - mg = 0

where n = magnitude of normal force and mg = weight of the block. It follows that n = mg.

When the block is at rest, the applied force X will not be enough to move the box until it can overcome the maximum mag. of static friction. If µ[s] is the coefficient of static friction, then the maximum mag. of the frictional force is

f = µ[s] n = µ[s] mg

The net horizontal force would be

∑ F [hor] = X - µ[s] mg = 0

so a minimum force of X = µ[s] mg is required to get the block moving. Any mag. smaller than this and the block stays at rest/in equilibrium.

Once the mag. of X exceeds µ[s] mg, the block will begin to move. At that point, if the coefficient of kinetic friction is µ[k], then the net force on the block is

∑ F [hor] = X - µ[k] mg = 0

so a minimum force of X = µ[k] mg would be needed to keep the block moving at constant speed, or otherwise X = µ[k] mg + ma if the block is accelerating with mag. a.

Ranking the following according to the wavelength of radiant energy emitted, from the shortest wavelength to the longest:

The shortest wavelength:

1. A light bulb with a filament glowing at 4000°C

A light bulb with a filament glowing at 4000°C emits visible light, which corresponds to a range of wavelengths in the electromagnetic spectrum.

As the temperature increases, the filament emits shorter-wavelength visible light, including blues and violets, which have relatively shorter wavelengths compared to other sources.

2. A car engine at 140°C

A car engine at 140°C emits thermal radiation in the infrared region of the electromagnetic spectrum. Infrared radiation has longer wavelengths than visible light. While the exact spectrum of an engine's thermal radiation depends on various factors, the emitted wavelengths are generally longer than those emitted by a glowing filament in a light bulb.

The longest wavelength:

3. A rock at room temperature

A rock at room temperature primarily emits thermal radiation in the far-infrared range, commonly referred to as "heat radiation."

The wavelengths of this radiation are longer than both visible light and the infrared radiation emitted by a car engine. As a result, the rock's thermal radiation has the longest wavelengths among the three sources listed.
