A vector has horizontal and vertical components.
The value of [tex]\mathbf{\theta }[/tex] is 45 degrees, when the horizontal and vertical components are equal
Let the magnitude of the vector be H.
So, the horizontal (h) and the vertical components (v) of the vector would be:
[tex]\mathbf{v = Hcos(\theta)}[/tex] --- vertical
[tex]\mathbf{h = Hsin(\theta)}[/tex]
Equate both expressions
[tex]\mathbf{h = v}[/tex]
Substitute values for h and v
[tex]\mathbf{Hcos(\theta) = Hsin(\theta)}[/tex]
Divide both sides by H
[tex]\mathbf{cos(\theta) = sin(\theta)}[/tex]
When [tex]\mathbf{cos(\theta) = sin(\alpha)}[/tex], then
[tex]\mathbf{\theta + \alpha = 90^o}[/tex]
So, we have:
[tex]\mathbf{\theta + \theta = 90^o}[/tex]
[tex]\mathbf{2\theta = 90^o}[/tex]
Divide both sides by 2
[tex]\mathbf{\theta = 45^o}[/tex]
Hence, the value of [tex]\mathbf{\theta }[/tex] is 45 degrees

A chamber contains equal molar amounts of c₂h₂, ch₄, and h₂. If the total chamber pressure is 5. 00 atm, then the partial pressure of c₂h₂ is:.
Answer:
I don't know answer what
The partial pressure of c₂h₂ is25 atm.
What is partial pressure?When more than one gas is present in a container, each gas exerts pressure, which is known as partial pressure. Its partial pressure refers to the pressure of any gas inside the container.
Partial pressures can be calculated in one of two ways:
To determine the individual pressure of each gas in a mixture, use PV = nRT. Determine the proportion of pressure from the total pressure that may be assigned to each individual gas by using the mole fraction of each gas.When there is a combination of two or more gases in a given volume, the pressure created by each individual gas in the mixture is expressed using the phrase partial pressure.
The partial pressures of the individual gases make up the total pressure of the gas combination. P1 + P2 + P3 = Ptot = Pi

A hemisphere of radius 8 sits on a horizontal plane. A cylinder stands with its axis vertical, the center of its base at the center of the sphere, and its top circular rim touching the hemisphere. Find the radius and height of the cylinder of maximum volume.
The dimensions of the cylinder that has the maximum volume can be
found be finding the maximum value of the volume function.
[tex]\mathrm{The \ \underline{height \ of \ the \ cylinder \ of \ maximum \ volume \ is \ \dfrac{8}{\sqrt{3} }}}[/tex][tex]\mathrm{The \ \underline{radius \ of \ the \ cylinder \ of \ maximum \ volume \ is \ \dfrac{8 \cdot \sqrt{6} }{3}}}[/tex]Reasons:
The known parameter of the hemisphere are;
The radius of the hemisphere = 8
Required;
The radius and height of the maximum volume of the inscribed cylinder.
Solution:
Let h represent the height of the cylinder, and let r represent the radius of
the cylinder, we have;
r² + h² = 8²
Therefore;
r² = 8² - h² = 64 - h²
r² = 64 - h²
The volume of the cylinder, V = π·r²·h = π·(64 - h²)·h
V(h) = π·(64·h - h³)
At the maximum volume, we have;
[tex]\dfrac{dV(h)}{dh} = \dfrac{d}{dh} \left(\pi \cdot \left(64 \cdot h - h^3 \right) \right) = \pi \cdot \left(64 - 3 \cdot h^2 \right) = 0[/tex]
64 - 3·h² = 0
64 = 3·h²
[tex]h =\sqrt{\dfrac{64}{3} } = \dfrac{8}{\sqrt{3} }[/tex]
[tex]\underline{\mathrm{The \ height \ of \ the \ cylinder, \ h} = \dfrac{8}{\sqrt{3} }}[/tex]
[tex]r^2 = 64 - \dfrac{64}{3} = \dfrac{128}{3}[/tex]
[tex]r =\sqrt{\dfrac{128}{3}} = \dfrac{8 \cdot \sqrt{6} }{3}[/tex]

Which statements correctly characterize asoka's reign? select all correct answers.
Answer:
Roads, hospitals, and monuments were built.
Buddhism spread through missionary monks.
Explanation:
Asoka was the founder of the Moorish dynasty, and extended the kingdom to the western half of northern India. His endeavor, accompanied by fearsome bloodshed, provoked profound spiritual upheavals at Asoka, after which he embraced Buddhism, which had appeared in Magadha two centuries earlier. Since then, the cruel Asoka has become known as the godly Asoka. In the words of the emperor himself, since then his sound was no longer booming, but the voice of dharma.
During his rule, he pursued an official policy of non-violence. The unnecessary killing and mutilation of animals has been abandoned, such as hunting for hunting and stamping.
Asoka also showed mercy to the captives, allowing them a day of freedom each year, and providing ordinary citizens with free education at universities. He treated subjects as equals regardless of religion, politics or caste and made free hospitals for both humans and animals. Asoka defined the main principles of nonviolence, tolerance of sects and opinions, obedience to parents, respect for teachers and priests, human treatment of servants (slavery did not even exist in India at that time) and generosity to all. These reforms are described by Asoka's edicts.

Using a t-distribution table or a t-critical value calculator, the critical value for a one- tailed t - test for the sample given at 0.05 α-level would be 1.833
The critical value for a one-tailed, paired sample t test can be defined thus :
