40.1L volume of h2 gas that is measured at 26 c and 100 kpa will be produced from Na of mass given as 3.25g.

Kilopascal (kPa), a 1,000-fold increase in the meter-kilogram-second system’s measure of pressure and tension (the International System of Units [SI]).

Blaise Pascal, a French mathematician and scientist, is honored by its name.

The formula below can be used to translate kg/cm2 into kPa:

A kPa equals 1000 pascals (Pa)

1 kg/cm2 is equal to 98066.5 pascals (Pa), or kPa value multiplied by 1000 Pa.

Thereafter,

T = 26°C

= 299K

P = 100kPa

P= 100/101.325

=0.986923 atm

mass = 3.25g

Atomic mas of H = 1.00784

molar mass of H2 gas = 2x10.00784

= 2.01568g/mol

mole of H2 in 3.25g = 3.25/2.01568 = 1.612359 mol

This gas provided in the question follows the ideal gas equation, so it can be written as

PV = nRT

⇒ V = nRT/P

= (1.612359x 0.0821x 299) / 0.986929

⇒ V = 40.104473

V = 40.1 L

Thus, the volume of gas was found to be 40.1Liter.

Nuclear fusion can release large amounts of energy is the True statement.

The nuclear fusion reaction occurs when two or more atom combine together to form a heavier atom. For example, when two hydrogen atoms fuse to form one helium atom.

This is the same process that powers the sun and creates huge amounts of energy several times greater than fission. It also doesn't produce highly radioactive fission products.

The nuclear fusion reaction releases large amount of energy, because Fusion reactions have an energy density many times greater than nuclear fission.

The reactions that produces far greater energy per unit of mass but even though the individual fission reactions are generally much more energetic than individual fusion ones, which are themselves millions of times more energetic than chemical reactions.

The heat energy in kj that is produced is 7.21kj  given that the temperature change observed is 11.5 c when 4.436 g of naoh are added to 150.0 ml of water

It is given that 4.436g is the mass of NaOH. The density and volume of water it has been added to was also given.

We need to convert the water's volume to mass

Density = mass / volume

Thus, mass = density * volume

150.0mL H2O * (1.000 g/mL) = 150.0 g H2O.

Now simply add the two masses: 150g + 4.436g = 154.436g

Q = mcdT

Q = heat added or removed

m = mass of substance = 154.436g

c = specific heat of this solution is 4.06j/g C

dT = change in temperature

Q = 154.436g * 4.06 * 11.5

The blurring effects of the Earth's atmosphere would decide the smallest angular size that this telescope could resolve.

The term "angular size" refers to an object's apparent size as seen from an observer on Earth. The least angular size can be affected by the magnitude of lights received by telescopes, which can be changed by the earth's hazy atmosphere. Telescopes collect and amplify light from distant objects. Earth's atmosphere substantially limits astronomical observations for two basic reasons.

First, not all atmospheric wavelengths are equally transparent, and some wavelength regimes are completely out of range for ground-based telescopes. Therefore, while developing a telescope with a specific angular size, the earth's atmosphere must be considered.

When Fez engages in team activities such as running or passing the ball, they are maintaining tension with an equal force on all sides.

Any physical object that is in contact with another one can apply forces to that object. The pulling force transmitted axially by a string, cable, chain, or other similar object, or by each end of a rod, truss member, or other similar three-dimensional object is referred to as tension. The action-reaction pair of forces acting at each end of said elements can also be referred to as tension.

The force produced when a load is applied at one or more of the ends of a material in a direction away from the material's cross-section is known as the tension force. It's common to describe a tension force as a "pulling" force. To exert a tension force on the material, the load must be applied axially.

Total distance traveled by an object traveling at an average speed of

0.0470 km/h for 2min 33s is 1.99 m.

Distance is defined as an object's entire movement without regard for direction. Distance may be defined as how much ground an item has traversed regardless of its starting or finishing place.

The following equation can be used to determine the distance traveled by an object traveling at an average speed:

distance traveled = average speed * time

When is this:

Given,

average speed = 0.0470 km/h

converting average speed from km/h to m/s

                           = 0.01305556 m/s

time = 2min 33s

converting time in seconds

       = 153s

thus, we know that

distance traveled = average speed * time

                              = 0.01305556 * 153

                              = 1.99 m

P is referred as the pressure, which is measured in atmospheres (atm),

V is referred as the volume, which is measured in cubic meter ([tex]m^{3}[/tex]),

T  is referred as the temperature, which is measured in kelvin (K),

R  is referred as the ideal gas law constant , i.e., 0.0821 atm(L)/mol(K),

n is known as the number of moles (mol).

Given that,

P = 1 atm = 101 325 Pa

This law was coined by Isaac Newton and it states that when object X exerts a force on another object Y, the object Y must exert a form of counter force which has the same magnitude but opposite in direction.

In the case of the rudder, it redirects the fluid which then exerts an equal force of the same magnitude and an opposite direction. This thereby results in the motion of the boat and is therefore the most appropriate choice.

The frequency of electromagnetic waves is 22.32 x 10⁹ Hz or 22.32 GHz.

We need to know about electromagnetic waves to solve this problem. Electromagnetic waves can propagate without media. The speed of electromagnetic in vacuum media is equal to the speed of light. Hence, the wavelength and frequency can be determined as

c = λ . f

where c is the speed of light (3 x 10⁸ m/s), λ is wavelength and f is frequency.

From the question above, we know that

λ = 13.44 mm = 0.01344 m

By substituting the given parameter, we can calculate the frequency of microwaves

c = λ . f

f = c / λ

f = 3 x 10⁸ / 0.01344

f = 22.32 x 10⁹ Hz

The thickness of an anti-reflective coating is 96 nm.

Define Wavelength?

The wavelength in waves is defined as the distance between the crests and troughs. It can be calculated in the meter in the SI system. The crest is the upper part of the wave, and the trough is the lower part.

Given that,

The index of the anti-reflective coating is n = 1.3

The wavelength is denoted as  λ = 500 nm = 500×[tex]10^{-9}[/tex]m

The expression for interference can be written as

2t = (m+½)λf

m=0 is the minimum reflection order.

λf is referred to as the wavelength of the film.

By substituting the values in the above expression we get,

2t = (m+½)λf

2t = (0+½)λf

t = λf/4 (this will noted as equation 1 for more clarity )

The wavelength of the light in a medium with refractive index can be expressed as

λf = λ/n

By substituting the values in equation1 we get,

t = λf/4

t = (λ/n)/4

t = λ/4n = 500/(4×1.3) = 96 nm.
