'''In a series circuit, the sum of the voltages consumed by each individual resistance is equal to the source voltage. Components connected in parallel are connected along multiple paths so that the current can split up; the same voltage is applied to each component.''

Answer: Exothermic

Explanation:

An exothermic reaction causes an increase in temperature. This is because the energy released when the bonds are broken among the reactants is greater than than the energy absorbed when new bonds are formed among the products. This leftover energy gets passed along to the surroundings, where it produces a measurable increase in heat.

The mass of A remaining after 0.816 min is 9.42 g.

Convert the temperature to Kelvin: 300 °C + 273.15 = 573.15 K.

Use the following equation to calculate the rate constant (k) at the given temperature:

ln(k2/k1) = (Ea/R) x ((1/T1) - (1/T2))

where k1 is the rate constant at a reference temperature (usually 298 K), k2 is the rate constant at the given temperature, Ea is the activation energy of the reaction, R is the gas constant (8.314 J/mol.K), T1 is the reference temperature in Kelvin, and T2 is the given temperature in Kelvin.

Assuming the activation energy (Ea) to be 100 kJ/mol, we get:

ln(k/0.0422) = (100000/8.314) x ((1/298) - (1/573.15))

k = 0.159 s^-1

Use the first-order rate equation to calculate the amount of A remaining after 0.816 min:

ln(Nt/No) = -kt

where Nt is the amount of A remaining after time t, No is the initial amount of A, k is the rate constant, and t is the time elapsed.

Substituting the given values, we get:

ln(Nt/19.10) = -0.159 x (0.816 x 60)

Nt = 9.42 g

Potential energy plus kinetic energy are combined to form mechanical energy. According to the principle of mechanical energy conservation, mechanical energy is constant in an isolated system when only conservative forces are acting on it.

E mechanical = U + K

E mechanical = mechanical energy

U = potential energy

K = kinetic energy

Mechanical energy, also known as kinetic energy or potential energy, is the energy that an object possesses when it is in motion or the energy that an object stores due to its location.

Renewable energy is also fueled by mechanical energy. In order to efficiently produce electricity or convert energy, many sources of renewable energy depend on mechanical energy.

Applying,

Mechanical Energy (M.E.) = ((1/2)mv²) + (m × g × h)

                                          = ((1/2)*100*45²)+(100*9.8*12)

Answer:

The object with a higher mass has three times the kinetic energy of the less massive object.

We know that K.E.= 1/2 mv²

mass of first object = 1kg

speed = v

So K.E. = 1/2mv²

= 1/2 × (1) × v²

=

\( \: \: \: \: \: \: \: \: \: = \frac{1}{2} {v}^{2} \\ \)

Now the mass of second body = 3kg

speed = v

So K.E. = 1(3)v²/2

=

\( \: \: \: \: \: \: \: \: \: = \: \: \frac{3}{2} {v}^{2} \\ \)

now

K.E of first / KE of 2nd

\( \frac{1}{2} {v}^{2} \div \frac{3}{2} {v}^{2} \\ \)

\(\frac{ \frac{ke \: of \: first \: }{ - - - - - - - - - - -} }{ \frac{ke \: of \: 2nd}{} } = \frac{ \frac{1}{ - -} }{ 3 } \\ \\ so \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ 3(ke \: of \: first \:) = ke \: of \: 2nd\)

Leptin is released by adipocytes, and I predict that the levels of leptin would be decreased in Nicole when compared to a healthy, female adult of similar age and weight.

The body regulates itself in two ways, neural signals and hormones. Hormones are chemical messengers released by endocrine glands into the blood stream that carry out a particular function in the body. The hormone that regulates appetite and body weight is leptin.

Leptin is released by fat storing cells in the body called adipocytes. The word 'leptin' comes from a Greek word 'leptos' meaning 'fat controller', perfectly fitting its function. Since leptin is stored in the fat tissues, a person's weight has a direct effect on the levels of leptin in a person. When we lose weight, the amount of leptin circulating in the body decreases, leading to more appetite and weight gain.

A lack of leptin in the body, arising from genetic diseases results in uncontrolled appetite and obesity. Generally, female adults also produce less leptin than male adults

The amount of time between when a star rises and when it sets depends on the star's declination and the observer's latitude. On average, a star takes around 12 hours to complete its journey across the sky.

The time between when a star rises and sets depends on the star's declination, which is its angular distance north or south of the celestial equator, and the observer's latitude. Stars with a declination close to the celestial equator will take the shortest amount of time to complete their journey across the sky, while stars with a declination closer to the celestial pole will take the longest. This is because stars closer to the pole have a smaller apparent motion across the sky.

On average, a star takes around 12 hours to complete its journey across the sky, from rising in the east to setting in the west. This means that for half of the day, a particular star will be visible in the sky, and for the other half of the day, it will be below the horizon. However, the exact amount of time between when a star rises and when it sets will vary depending on the star's declination and the observer's latitude. For example, at the equator, a star with a declination of 0 degrees will take about 12 hours to complete its journey across the sky, while at the North Pole, the same star will be visible for the entire 24-hour period.

When electromagnetic radiation is Doppler-shifted by motion away from the detector, the observed wavelength increases.

When an object emitting electromagnetic radiation, such as light, is moving away from an observer (detector), the wavelengths of the observed radiation are stretched or increased.

This phenomenon is known as the Doppler shift. It occurs because the motion of the source affects the perceived frequency or wavelength of the radiation. When the source is moving away, the observed wavelength is longer compared to the emitted wavelength.

This effect can be observed in various contexts, such as the redshift observed in the light from distant galaxies, indicating their recession from us due to the expansion of the universe.

Additionally, it is relevant in understanding the behavior of stars, galaxies, and other astronomical objects. By analyzing the Doppler shift, scientists can infer important information about the motion and velocity of celestial objects.

Answer:

Approximately \(3.7\; {\rm N \cdot kg^{-1}}\) (or equivalently, \(3.7\; {\rm m\cdot s^{-2}}\).)

Explanation:

Gravitational field strength measures the force (weight) that the field exerts on object of unit mass (e.g., \(1\; {\rm kg}\).)

Divide the weight of the object by its mass to find the gravitational field strength at the position.

In this question, \(\text{weight} = 55.5\; {\rm N}\) while \(\text{mass} = 15\; {\rm kg}\). Therefore, the gravitational field strength will be:

\(\begin{aligned} & (\text{gravitational field strength}) \\ =\; & \frac{(\text{weight})}{(\text{mass})} \\ =\; & \frac{55.5\; {\rm N}}{15\; {\rm kg}} \\ =\; & 3.7\; {\rm N \cdot kg^{-1}} \end{aligned}\).

The correct answer is C.

The ball is projected horizontally with a velocity of 1.5 m/s from a cliff and the ball hits the ground 1.22 s after it leaves the cliff.

We need to find out which row in the table shows the horizontal velocity, vertical velocity and the vertical displacement of the ball just before it hits the ground.

So, we know that,

u = 1.5 m/s (horizontal velocity) and

t = 1.22 s.

Now, horizontal distance covered by the ball,

S = ut=1.5×1.22=1.83 m.

So, we can conclude that at the time of hitting the ground, the horizontal displacement of the ball is 1.83m.

The vertical velocity at the time of hitting the ground can be calculated as:

v = u + gtw

here g = 9.8 m/s² (acceleration due to gravity)

v = 0 + 9.8(1.22)

v = 11.956 m/s

The ball is dropped from rest, so the initial vertical velocity is 0.

The time taken to hit the ground is t = 1.22 s.

The vertical displacement at the time of hitting the ground can be calculated as:

s = ut + 0.5gt²

s = 0 + 0.5(9.8)(1.22)²

s = 7.45 m

So, the row (c) in the table shows the horizontal velocity, vertical velocity and the vertical displacement of the ball just before it hits the ground.

Hence, the correct option is (c) (1.5 m/s, -11.96 m/s, 7.45 m).

The lenses of a diving mask are curved on the inner surface only

The primary goals of treated lenses are to either protect your eyes from surface glare or enhance colors underwater. As divers we learn that water absorbs light as we go deeper, these anti-reflective coatings further improve light transmittance into the mask, thus increasing brightness also The lenses of a diving mask are curved on the inner surface only.

This is great for divers who spend a lot of time on the surface or divers who like to appreciate enhanced colors underwater – photographers will also appreciate the glare reduction underwater.  The tint of the treatment in some masks makes it hard for you to see the diver's eyes – so for instructors, tinted masks aren’t usually their go-to, as their students won’t be able to see their eyes.
