How lrge a force is necessary to stretch a 1.1 m diamter steel wire (y = 2.0 * 10^11 ) by 2.0 percent

An electric field that has a constant field strength value throughout is said to be uniform. Since the field strength is constant and the field lines are generally parallel and evenly spaced from one another in a uniform electric field. Their separation is equal.

Each point in space has an electric field associated with it when there is a charge present in any form. The value of E, often known as the electric field strength, electric field intensity, or just the electric field, expresses the strength and direction of the electric field.

The two principal factors that affect the force of air resistance on a falling object are speed  and  cross-sectional area of the object.

When an object falls through the air, it mostly encounters some sort of resistance to its speed and this resistance is known as air resistance.

This resistance is present because of the collisions of the air molecules with the frontal surface molecules of the object.

As the speed is increased of the object so that increased amount of air resistance. speed of the object is directly proportional to the air resistance.

The cross-section of solid is defined as the shape obtained by the intersection of solid by a plane .

The rate of change of distance with respect to time is known as speed.

The Latent heat of fusion is also known as the Enthalpy of Fusion. It is a kind pf change in enthalpy.

The latent heat of fusion, is the change in enthalpy that takes place when energy, typically heat, is provided to a specific quantity of a substance to causes it to change from a solid state to a liquid state at a constant pressure.

For instance, 1 kilogram of ice melts at 0 °C at a variety of pressures, absorbing 333.55 kJ of energy without causing a change in temperature.

The heat of solidification, which occurs when a substance changes from a liquid to a solid, is equal and opposing.

This energy includes the contribution necessary to displace its surroundings against ambient pressure in order to accommodate any corresponding change in volume.

The melting point or the freezing point, depending on the situation, is the temperature at which the phase transition takes place. Conventionally, unless otherwise stated, the pressure is taken to be 1 atm (101.325 kPa).

The formula of latent heat of fusion is L= q/m

Here q is the heat provided and m is the mass of the object.

So, L = 24j/6kg

L= 4j/kg

So, the latent heat of fusion is 4 j/kg

The predominant protonation state and charge of the His and Asp side chain will be predominantly protonated and positively charged if both its p[tex]K_{a}[/tex] values is more than 5.

We know that,

pH = p[tex]K_{a}[/tex] + ( log [ [tex]A^{-1}[/tex] ] / [ HA ] )

where,

[ [tex]A^{-1}[/tex] ] represents deprotonated form

[ HA ] represents protonated form

Consider pH = p[tex]K_{a}[/tex]

In this case,

[ [tex]A^{-1}[/tex] ] / [ HA ] = 1

This means that protonated and deprotonated forms are equal.

This also means that as pH decreases, the acid's state will be predominantly protonated and its charge will be positive.

The relationship between pH and p[tex]K_{a}[/tex] shown above is known as Henderson-Hasselbach equation

As the liver cells of animals, carbohydrates are kept in glycogen granules close to the inner membrane. On demand, these release energy.

In addition to human muscle and liver cells, other cells such as those in the brain, heart, smooth muscle, kidney, red and white blood cells, and even adipose tissue also store modest amounts of glycogen.

Glucose is stored in the form of glycogen. It is a sizable, multi-branched polymer of glucose that is converted back into glucose in response to glucagon and accumulates in response to insulin. The fact is that because fat is such an energy-dense molecule and contains so many calories per gram, ounce, or pound, it is far simpler to lose weight when your body burns carbohydrates instead of fat.

Einstein was the first to postulate that light is made up of photons, which are essentially energy bundles.

A photon is a microscopic particle made up of electromagnetic radiation waves. Maxwell demonstrated that photons are merely electric fields moving through space. Photons move at the speed of light and have no charge or rest mass. Charged particles produce photons, though they can also be produced by other processes, such as radioactive decay.

It's common to refer to photons as energy packets. This analogy is excellent because a photon has uncondensable energy. An alternating electric field is how this energy is kept in reserve. The universe's size, which is the longest theoretical wavelength of light, and the Planck length, which some theories claim to be the smallest, have never been measured. These energy packets may travel great distances without losing energy or speed. In vacuum, photons move at the speed of light, which is 2.997 x 108 m/s.

On Venus, only 10% of the incoming solar radiation reaches the surface; most of it is reflected back into space by the planet's dense cloud cover, making Venus appear to shine brightly in the night sky.

Despite the small amount of solar radiation reaching the surface, it is trapped effectively by gases in lower atmosphere, giving rise to the high temperatures.

Scientists think that the Venus was once more like the Earth, but at some point it started heating up uncontrollably.  Any water that may have once existed in oceans on the surface evaporated into atmosphere causing further runaway heating.
