The correct answer would be electromagnetic waves.

Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles are closer together than in gases, where particles are further apart.

The Sun's energy gets to the Earth through radiation, which you can prove just by standing outside and letting the sun's rays warm your face on a sunny day. Every object around you is continually radiating unless its temperature is at absolute zero, at which point its molecules completely stop moving.

The unique use of gamma radiation is Killing bacteria. The correct option is D.

Gamma radiation is a type of electromagnetic radiation that is highly energetic and has no mass or charge. It is the most penetrating form of radiation and is often emitted during radioactive decay or nuclear reactions. Gamma rays have the shortest wavelengths and highest frequencies in the electromagnetic spectrum, ranging from about 0.1 nanometers to 10 picometers in wavelength. They can cause ionization in matter, meaning they can knock electrons out of atoms or molecules, making them highly damaging to living tissue. Gamma radiation is commonly used in medical imaging and cancer treatment, as well as in industrial applications for sterilization and food preservation.

Here in the Question,

Option A. Detection of thyroid cancer: Gamma radiation is used in medical imaging techniques such as PET scans and SPECT scans to diagnose cancerous conditions, but it is not unique to the detection of thyroid cancer.

Option B. CT scanners: Gamma radiation is not used in CT (computed tomography) scanners. CT scanners use a series of X-rays to produce detailed images of the inside of the body.

Option C. Smoke detectors: Smoke detectors use a small amount of radioactive material, typically americium-241, to ionize air particles and detect the presence of smoke. While gamma radiation is a type of ionizing radiation, smoke detectors do not use gamma radiation specifically.

Option D. Killing bacteria: Gamma radiation is used in the food industry to kill bacteria and sterilize food products, such as spices, meat, and poultry. This is a unique use of gamma radiation, as it relies on its ability to destroy microorganisms at high doses while leaving no residual radiation.

Therefore, The correct answer is option D i.e Killing bacteria.

It is true that temperature and pressure are intensive quantities which are independent of size of the object.

Intensive quantity means independent of mass or volume. Properties needed to define state of matter can be intensive or extensive i.e. mass independent or mass dependent.

We know very well that pressure is force per unit area.

Consider a situation where a gas is enclosed in the close vessel of volume V and it's molecules exert the pressure P on the walls now insert the partition in between now the volume and mass of the gas in each section has become half but the intermolecular forces between the gas molecules and the wall and among the molecules  remains unaffected ,the Value of pressure remains unchanged for both of the sections i.e. =P

Similarly, temperature is not dependent on the amount of molecules of any gas, liquid, due to that on changing amount of molecules temperature isn't change.

The width of the slit is approximately 0.00055 meters, or 0.55 millimeters.

To find the width of the slit, we will use the formula for the angular position of the first dark fringe in a single-slit diffraction pattern:
sin(θ) = (mλ) / a
Where θ is the angular position of the dark fringe, m is the order of the dark fringe (m = 1 for the first dark fringe), λ is the wavelength of the light (700 nm), and a is the width of the slit.

1. Calculate θ: tan(θ) = (distance from the center to the fringe) / (distance from the slit to the screen) = 0.032 m / 2.5 m. Solve for θ: θ ≈ 0.0128 radians.

2. Use the formula to find the width: sin(θ) = (1 * 700 * 10^-9 m) / a. Rearrange the formula: a = (1 * 700 * 10^-9 m) / sin(θ) ≈ 0.00055 m or 0.55 mm.

The foundation pressure at the bottom of the dam is 470,400 Pascals or 470.4 kPa

To determine the foundation pressure at the bottom of the dam, we can use the concept of hydrostatic pressure. Hydrostatic pressure is given by the formula:

Pressure = Density x Gravity x Height

First, let's calculate the density of water using the specific gravity of concrete. The specific gravity is the ratio of the density of a substance to the density of water.

Specific gravity of concrete = Density of concrete / Density of water

2.4 = Density of concrete / 1000 kg/\(m^3\) (density of water)

Density of concrete = 2.4 x 1000 kg/\(m^3\)= 2400 kg/\(m^3\)

Next, let's calculate the height of water acting on the vertical sides of the dam. The height is given as 20m.

Now, we can calculate the foundation pressure at the bottom of the dam using the formula for hydrostatic pressure.

Pressure = Density x Gravity x Height

       = 2400 kg/m^3 x 9.8 m/s^2 x 20m

       = 470,400 Pa (Pascals)

So, the foundation pressure at the bottom of the dam is 470,400 Pascals or 470.4 kPa.

The energy output from active galactic nuclei is much greater than the energy output from normal galaxies, often by several orders of magnitude. Active galactic nuclei (AGNs) are powered by the accretion of  matter onto a supermassive black hole at the center of the galaxy.

This process releases enormous amounts of energy in the form of radiation and outflows of material, such as jets of highly energized particles that can extend thousands of light-years from the black hole. In contrast, normal galaxies are powered primarily by the nuclear fusion reactions that take place in their stars. The energy output from AGNs can be so great that it can significantly affect the surrounding environment and even influence the evolution of the galaxy itself. For example, the intense radiation from an AGN can ionize gas in the galaxy, creating regions of hot, glowing gas known as emission nebulae. The outflows of material from an AGN can also help to regulate star formation in the galaxy by heating or expelling gas from the interstellar medium.

If Callisto's orbit were circular, then how many days would it take Callisto to complete one full revolution around Jupiter is 16.7 days. If Callisto's orbit were circular, what would its orbital speed be is 8.20 × 10³ m/s.

Radius of Callisto, rc = 2.40 × 10⁶ m

Mean orbital radius, r = 1.88 × 10⁹ m

The time required for Callisto to complete one full revolution around Jupiter is given by: T = 2πr/v

where, T is the period of revolution, v is the speed of Callisto, and r is the mean orbital radius.

If Callisto's orbit were circular, then its speed would be constant, and the time required to complete one full revolution would be the same as its period of revolution.

T = 2πr/v = (2π)(1.88 × 10⁹ m)/(8.20 × 10³ m/s) ≈ 1.67 × 10⁶ s ≈ 16.7 days

The speed of Callisto in a circular orbit is given by:

v = 2πr/T = (2π)(1.88 × 10⁹ m)/(1.67 × 10⁶ s) ≈ 8.20 × 10³ m/s

Hence, Callisto's orbit were circular, then how many days would it take Callisto to complete one full revolution around Jupiter is 16.7 days. If Callisto's orbit were circular, what would its orbital speed be is 8.20 × 10³ m/s.
