17.90 KJ of energy must be added to 69. 0 grams of water to change the temperature from 33°C to 95°C

Specific heat, the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. The units of specific heat are usually calories or joules per gram per Celsius degree.

Heat added = H = mc(ΔT )

where,

H = heat

m = mass of water = 69 g

c = specific heat of water = 4.184 J/g/°C

ΔT = change in temperature

H = 69 * 4.184 * ( 95 - 33 )

H   = 17899.152 J

     = 17.90 KJ

Possible beat frequencies with tuning forks of frequencies 255, 258, and 260 Hz are 2, 3 and 5 Hz respectively.

The beat frequency refers to the rate at which the volume is heard to be oscillating from high to low volume. For example, if two complete cycles of high and low volumes are heard every second, the beat frequency is 2 Hz. The beat frequency is always equal to the difference in frequency of the two notes that interfere to produce the beats. So if two sound waves with frequencies of 256 Hz and 254 Hz are played simultaneously, a beat frequency of 2 Hz will be detected. A common physics demonstration involves producing beats using two tuning forks with very similar frequencies. If a tine on one of two identical tuning forks is wrapped with a rubber band, then that tuning forks frequency will be lowered. If both tuning forks are vibrated together, then they produce sounds with slightly different frequencies. These sounds will interfere to produce detectable beats. The human ear is capable of detecting beats with frequencies of 7 Hz and below.

A piano tuner frequently utilizes the phenomenon of beats to tune a piano string. She will pluck the string and tap a tuning fork at the same time. If the two sound sources - the piano string and the tuning fork - produce detectable beats then their frequencies are not identical. She will then adjust the tension of the piano string and repeat the process until the beats can no longer be heard. As the piano string becomes more in tune with the tuning fork, the beat frequency will be reduced and approach 0 Hz. When beats are no longer heard, the piano string is tuned to the tuning fork; that is, they play the same frequency. The process allows a piano tuner to match the strings' frequency to the frequency of a standardized set of tuning forks.

The angle between the transmission axes of the polarizers if it is desired that one-tenth of the incident intensity be transmitted, ∝ = 63.435°

We'll assume that [tex]I_{0}[/tex] represents the incident light's intensity. Two polarizers are provided to us, but the first polarizer's angle is not disclosed. The incident light in situations like this needs to be unpolarized. This is due to the fact that, regardless of angle, the transmitted intensity via the polarizer is reduced by half for unpolarized light:

[tex]I_{1} =\frac{1}{2} I_{0}[/tex]

Then,

[tex]I_{2} =\frac{1}{10} I_{0}[/tex]

By using Malu's law,

[tex]I_{2} =I_{1} cos^{2} \alpha[/tex]

That is,

[tex]cos^{2} \alpha = \frac{I_{2} }{I_{1} }[/tex]

In terms of [tex]I_{0}[/tex], we get

[tex]cos^{2} \alpha =\frac{0.1I_{0} }{0.5I_{0} }[/tex]

[tex]cos^{2} \alpha = 0.2[/tex]

Now the angle is,

[tex]cos\alpha =\sqrt{0.2}[/tex]

cos ∝ = 0.44721

[tex]\alpha =cos^{-1} (0.44721)[/tex]

Then, ∝ = 63.435°

Chyme is a semi-liquid paste that results from the mixing of partially digested food with gastric juice in the stomach.

When food enters the stomach, the gastric gland releases gastric juice, which the stomach's muscular wall thoroughly stirs into the meal. Chyme is the term for partially digested food that contains gastric juice.

Only a small amount of chyme is released into the small intestine at a time. The movement of chyme from the stomach into the small intestine is regulated by the pyloric sphincter.

In contrast, chyle is a milky body fluid made up of lymph and free fatty acids that have been emulsified (FFAs). While roughage refers to the inorganic fibre included in food, it is generated in the small intestine after the breakdown of fatty foods and taken up by lymph channels specifically known as lacteals.

Hi, your answer is below.

Time dilation is usually defined as the slowing of the passage of time experienced by objects in motion relative to an observer; measurable only a relativistic speeds.  Because time moves at various rates for the two of them depending on their relative velocities and/or proximity to things of considerable mass, if two persons (or objects) are moving relative to one another, they will age at separate rates. They will age differently from one another over time since their two timepieces will really tick at separate speeds. If they cross paths again later, they will both have aged differently, which may be determined by using their own timepieces, presuming they each had one. Einstein's Special and General Relativity equations, which have undergone extensive testing over the past 115 years and have never been shown to falter, regulate this "time dilation." The general relativity theory of Einstein, which states that a huge body's gravity warps space-time around it, causes time to move more quickly or more slowly depending on how far away the mass is from the observer, is what causes this so-called "time-dilation" phenomenon.

The empirical formula of the antimony chloride is [tex]SbCl_{3}[/tex].

Chemical formulas for compounds that simply specify the proportions of the elements they contain rather than the exact number or arrangement of atoms are known as empirical formulas. The element in the compound with the lowest whole number ratio would be this one.

Data obtained from the question

Antimony (Sb) = 0.338 g

Chlorine (Cl) = 0.295 g

Divide by their molar mass.

Sb = 0.338 / 122 = 0.0028

Cl = 0.295 / 35.5 = 0.0083

C. the probability of Type II error decreases

Higher values of α make it easier to reject the null hypothesis, so choosing higher values for α can reduce the probability of a Type II error. The consequence here is that if the null hypothesis is true, increasing α makes it more likely that we commit a Type I error.

A Capacitor is a device consisting of two conductors that can be charged with equal and opposite charges, separated by a thin insulator.

According to principle of a capacitor, capacitor is a system of conductors or dielectric.

If there is a single conductor, it cannot holds very much current then its potential reaches to its maximum values and it cannot hold more charge.

If we place another conductor near it, its potential becomes low and it is able to store more charge.

We know from the definition of the capacitor, A capacitor is a two-terminal electrical device that possesses the ability to store energy in the form of an electric charge. It consists of two electrical conductors that are separated by a distance.
