Enzymes accelerate chemical reactions in cells.

Specifically lowering the threshold required to initiate the intended response. They do this by binding to another substance called a substrate. Enzymes are proteins that function as biological catalysts by accelerating chemical reactions. Molecules on which enzymes can act are called substrates, and enzymes convert substrates into various molecules known as products.

Enzymes are proteins that facilitate metabolism and chemical reactions in the body. Build some substances and break down others. All living things have enzymes. Our bodies naturally produce enzymes. Enzymes are proteins made up of amino acids linked together in one or more polypeptide chains. This arrangement of amino acids in the polypeptide chain is called the primary structure.

The centripetal acceleration of a speck of clay on the edge is 3.89 m/s².

We need to know about centripetal acceleration to solve this problem. The centripetal acceleration depends on the angular velocity and the radius. It can be written as

a = ώ² . R

where a is centripetal acceleration, ώ is angular velocity and R is radius.

From the question above, the given parameters are

ώ = 45 rpm

d = 35 cm

R = 35/2 = 17.5 cm = 0.175 m

Convert the angular velocity unit to rad/s

ώ = 45 rpm

ώ = 45 x 2π / 60 rad/s

ώ = 1.5π rad/s

By substituting the given parameters, we can calculate the centripetal acceleration

a = ώ² . R

a = 1.5π² . 0.175

a = 3.89 m/s²

White-dwarf supernovae occur only among young and extremely bright stars.

Two stars in a binary system revolve around the same location. A carbon-oxygen white dwarf, one of the stars, takes materials from its neighbouring star. The white dwarf eventually becomes overburdened with matter. A supernova is produced when a star explodes due to an excess of stuff.

According to a recent study, the supernova explosion of a white dwarf star could have effects similar to those of a nuclear bomb on Earth. White dwarfs are the dull, fading cores of dead stars, about the size of Earth, that remain after stars of average size have used up their fuel and lost their outer layers.

An eruption from the surface of a white-dwarf star in a binary star system is known as a nova. When a white dwarf, which is the dense core of a former normal star, "steals" gas from a neighbouring companion star, a nova is the result. When the white dwarf's surface accumulates enough gas, an explosion results.

Explanation:

Given that the boulder's pe value is 4037.6, the energy it possesses immediately before impact must be equal to the energy it had at the time it began. In this manner, the bolder's potential energy

When a particle, object, or collection of particles move, kinetic energy, the energy of motion, is demonstrated. Kinetic energy is the energy that is released when a moving object moves, such as when a person walks, a ball is thrown, food falls off a table, or a particle is charged by an electric field.

Potential energy that has been set into motion by factors like elastic forces or gravity can then be converted into kinetic energy. The power behind motion is called kinetic energy. An object's kinetic energy increases as force is applied to it, which causes it to move faster.

Explanation:

Astronomy Test 6

when forces along the body are transmitted to an adjacent structure, usually the floor or a piece of equipment is called Closed Kinetic chain .

A closed kinetic chain exercise, according to Steindler, occurs when the distal section encounters "substantial" external resistance that prevents unrestricted movement. As a result, neither the proximal nor the distal portions can move in this system.

Unfortunately, Steindler did not provide a numerical value for the word "substantial" in his original definition, which causes misunderstanding and disagreement over what constitutes a true closed kinetic chain movement. Except during isometric exercises, where there is no movement, true closed kinetic chain movement patterns never happen in the extremities.

However, in clinical practise, "resistance is imposed through the distal portion of the extremity and remains fixed to the extremities" is the definition of a closed kinetic chain. The standing squat is the best illustration of this since the feet stay firmly planted and the surface encounters significant resistance from the athlete's bodyweight or additional weight.

Due to its built-in functional stimulation, closed kinetic chain exercises have been used more and more in rehabilitation programmes for more than 20 years.

The magnitude of the electric field of the electromagnetic wave is E = 64.4 V/m

An electromagnetic wave is awave that does not require a medium to propagate

An electric field is a region in which the effect of an electric force is felt.

Since a nonsinusoidal electromagnetic wave like that described in section 32.2 has uniform electric and magnetic fields. the magnitude of the poynting vector for this wave is 11.0 W/m².

The magnitude of the poynting vector is given by

S = E²/μ₀c where

Since we require the electric field, making E subject of the formula, we have

E = √(Sμ₀c )

Given that S = 11.0 W/m²,

Substituting the value sof the variables into the equation, we have

E = √(Sμ₀c )

E = √(11.0 W/m² × 4π × 10⁻⁷ H/m × 3 × 10⁸ m/s)

E = √(44π × 3 × 10WH/s)

E = √(1320π WH/s)

E = √(4146.9 WH/s)

E = 64.4 V/m

When two systems are orthogonal, they do not impact one another through interaction. At some point or junction, they come together, but other from that, neither system affects the other.
