How do you calculate internal energy change?
Internal energy can be calculated by first law of thermodynamics as well as using specific heat.
From a microscopic perspective looking at a system at the atomic and molecular level, the internal energy U [J] of a system is the sum of the kinetic and potential energies of its atoms and molecules. Since the sum of kinetic and potential energies is mechanical energy, the internal energy of a system is the sum of atomic and molecular mechanical energies.
In other words, the internal energy is the total energy of the system associated with its microscopic constituents (made up of atoms and molecules) when viewed from a frame of reference that is stationary with respect to the body. Internal energy includes translational, rotational, and vibrational kinetic energies of molecules, potential energies within molecules, and potential energies between molecules.
In physics, the internal energy of a system is considered in terms of macroscopic properties that are very similar to atomic and molecular averages.
The internal energy change ΔU [J] is defined macroscopically as the difference between the absorbed energy Q [J] (as heat) and the emitted energy W [J] (as work).

What is the internal motion of particles called?
The internal motion of particles is called molecular motion.
According to the kinetic theory of motion of particles, the particles constituting a matter are in continuous random motion. Kinetic energy is possessed by particles due to their motions.
Molecular motions are affected by the factors of heat and temperature. With more heat given, the kinetic energy of particles increases, and they move fast and away from each other. This may result in a change of state. The state change may take place from solid to liquid or liquid to gas.
The formula showing the relation between kinetic energy and temperature is given as

A wheel of diameter 40. 0 cm starts from rest and rotates with a constant angular acceleration of 3. 00 rad/s2. At the instant the wheel has computed its second revolution, calculate the radial acceleration.
The radial acceleration is 80.27 m/s2.
The angular acceleration of the wheel is 3.00 rad/s2. In order for the wheel to complete two revolutions, it must have an angular displacement of 2π radians. Using the equation a = ω²r, we can calculate the radial acceleration of the wheel. Here, ω is the angular velocity, which is equal to the product of angular acceleration and time, 3.00 rad/s2 × t. Since the wheel has completed two revolutions, the total time elapsed is 2π/3.00 s. Plugging in these values, we get a = 3.00 × (2π/3.00)2 × (40.0/2) = 80.27 m/s2. Therefore, the radial acceleration of the wheel is 80.27 m/s2.

Highest Abundance: Yellow main-sequence star in an open cluster in the disk AND hot, blue main-sequence star in the disk.
Lowest Abundance: A red giant in globular cluster M13 AND a red main-sequence star in globular cluster M13.
What is abundance?
Astronomers classify all chemical elements heavier than hydrogen or helium as metals, even some that aren't typically thought of as metals, like carbon and oxygen. The percentage of these "metallics" in the stellar mass is consequently used to determine a star's metallicity. For the Sun, about 2%.
However, the chemical makeup of stars is not entirely captured by this concept. because there are practically unlimited ways to obtain the same amount of metal. For instance, a star with a certain metallicity may contain only iron, whereas a star with the same total metal content may have only oxygen. Every star in the universe contains every element listed on the periodic table, albeit their relative abundances vary from star to star.
Astronomers use the "abundance ratio," which is the logarithm of the ratio of the star's two metallic elements to the Sun, to determine the relative abundance of each element in a star.

in a gaseous mixture of massive molecules and light molecules with the same average ke, which have the greater speed?
The light molecules will have the greater speed, as their mass is much lower than that of the massive molecules. This means that they will have a higher kinetic energy per unit mass, which leads to a higher speed.
Comparing the Speeds of Massive and Light Molecules in a Gaseous MixtureThe speed of a molecule is determined by its kinetic energy, which is a measure of the energy of its motion. The kinetic energy of a molecule is proportional to its mass and the square of its velocity. Since the average kinetic energy (KE) of the two types of molecules in the mixture is the same, the lighter molecules will have a higher velocity than the massive molecules.
This is because they have less mass and the same amount of kinetic energy, so their velocity is higher in order to compensate for the lower mass. This means that the light molecules will have a greater speed than the massive molecules in the mixture.

you are holding two helium balloons, a large and a small balloon. how do the pressures of the helium compare?
The pressure of the helium comparison is like: in the large Helium Balloon is greater than the pressure in the small Helium Balloon
The huge helium balloon's increased pressure must result from the fact that there must be more moles of gas present. A balloon's walls are put under pressure when it is inflated because the air inside the balloon expands. The balloon's size consequently grows.
Temperature has an impact on the hot air balloon's internal pressure. The molecules move more quickly and forcefully against the interior wall of the balloon as they warm up. The force acting on a portion of the balloon is enhanced due to the gas particles' increased velocity, which results in an increase in pressure. The size of the balloon affects the air pressure inside as well. Pressure is inversely proportional to volume, V . If V were to double, P would drop to 1/2 its original value.

The force that causes atoms to connect chemically is another function of it.

a 5 kg ball and a 1 kg ball are dropped from the same height at the same time. which hits the ground first?
5 Kg will have a greater acclaration thus it will strike before 1 kg ball.
There are two cases
(Assuming same shape of both objects)
Without air
With air
Without air, In this case they will fall on ground at same exact time.
Because earth will give an equal acclaration to both the masses.
With air
In this case they will have force of M×g ('M' is their respective mass of each)
but impulsive force is constant so it will give different acclaration to both masses that will be :-
M×a = M×g - I(n)
(Here 'a' is acclaration 'I(n)' is impulsive force by the normal of air particle as they collide with the masses)
Thus :-
a = g - (I÷M)
As mass increase acceleration will be less decreased so
5 Kg will have a greater acclaration thus it will strike before 1 kg ball.

Given that about 25% of the mammalian genome is associated with genes, including introns and regulatory sequence, what would be the approximate average length of DNA per gene, if the genome contained 20,000 genes?
If the genome contained 20,000 genes, the average length of DNA per gene will be 40,000 base pairs.
Only 2.5% of the human genome is protein-coding. Introns make up the remaining 97.5%. The male nuclear diploid genome is 6.27 Gigabase pairs (GBP), 205.00 cm (cm) long, and 6.41 picograms in weight (pg). Female measurements are 6.37 GBP, 208.23 cm, and 6.51 pg.
For a 25% mammalian genome with 20,000 genes, the total number of base pairs, which is the length of DNA per gene, will be approximately double the number of genes contained in the genome, in this case, 40,000.

a circular ice rink of 25 m in diameter is enclosed by a hemispherical dome 35 m in diameter. if the ice and dome surfaces may be approximated as blackbodies and are at 0oc and 15oc, respectively, what is the net rate of radiative transfer from the dome to the rink?
The total rate of radiative transmission from of the roof to the rink is q 21=36881.89W.
What is an energy transfer that radiates?Radiative transfer is a physical phenomena that occurs when energy is transferred through electromagnetic radiation. Absorption, emission, or scattering processes all have an impact on how radiation travels through a medium. Mathematically, these interactions are described by the radiative transfer equation.
What constitutes radiative transfer in the atmosphere?In our numerical models, we describe solar and infrared radiation as well as how it interacts with clouds. There are several radiative processes at work in the atmosphere, including the absorption and emission of thermal radiation by gases, aerosols, cloud droplets, and ice crystals.
