The electrons lost from chlorophyll photooxidation are replaced by the oxidation of water. how many electrons are generated from the oxidation of one water molecule?

A charge q is located at the origin (0,0). the electric field at (x,y) is given (in terms of its components) by E1i^+E2j^+E3k^.

The size of the electric field produced by a point charge Q is determined by this equation. The distance r in the denominator is the separation between the point of interest and the point charge, Q, or the center of a spherical charge. Positive charge is moving in the opposite direction, toward a negative charge. Q1 will produce an E-field vector that points left at the origin, and Q2 will produce an E-field vector that points right. The electric force F, or Coulomb force, exerted per unit positive electric charge q at that place can be used to determine an electric field's strength, or E = F/q.

When there is a high energy demand, frequent variations in the energy demand, and a deficiency in oxygen, lactic acid is created and builds up in the muscle.

Muscle pH drops to between 6.4 and 6.6 during prolonged, severe exercise. The high H+ ion concentration does not seem to be the main factor limiting force creation; instead, the PCr level appears to be more important. High H+ concentrations can inhibit phosphofructokinase, although the inhibition can be effectively overcome by increases in the activators AMP and ADP. High H+ concentrations reduce PCr by directly affecting the equilibrium of creatine kinase and indirectly by raising ADP.

Explanation:

These are often calculated incorrectly because TIME is ignored

time = distance / rate

average rate =   distance / time

                      =   2d / ( d/40 + d/60)              2d is uphill + downhill

Venus is observed to orbit the sun every 0.62 years so the semi-major axis of venus's orbit is 0.73 au.

Celestial mechanics uses curved trajectory objects to describe orbits, such as a planet's orbit around a star, a natural satellite's orbit around a planet, or an artificial satellite's orbit around a planet, moon, asteroid, or Lagrange point. A circle, a whole circle's revolution, or a range of experiences are all examples of what is meant by an orbit. As an example, consider the earth's orbit around the sun. An illustration of how long an orbit or full circle around takes is the 365 days it takes the earth to travel around the sun. The planets are kept in their orbits by the gravity of the Sun. Since no other force in the Solar System can halt them, they remain in their orbits.

Answer:

Physics is a scientific discipline that seeks to construct and experimentally test theories of the physical universe. These theories vary in their scope and can be organized into several distinct branches.

MECHANICS :

Mechanics is the branch of physics that deals with the motion of an object without or with the reference of force. Mechanics can be further divided into two branches, namely quantum mechanics and classical mechanics. Quantum mechanics deals with the behaviour of the smallest particles like neutrons, protons, and electrons, while classical mechanics is the branch that deals with laws of motion of forces and physical objects.

OPTICS :

This branch of physics deals with the behaviour, propagation, and properties of light. Optics can be simply described as the study of the behaviour of infrared light, visible light, and ultraviolet.

THERMODYNAMICS:

Thermodynamics deals with the study of heat and its relation with work and energy. Thermodynamics also deals with the transmission of heat energy by means of convection, conduction, and radiation.

ELECTROMAGNETISM:

Electromagnetism deals with the study of electromagnetic force like electric fields, light, magnetic fields, etc. There are two aspects of electromagnetism which are “electricity” and “magnetism”.

RELATIVITY:

This branch of physics deals with the theorem that was formulated by Albert Einstein. The theory of relativity states that space and time are relative and all the motion must be relative to a frame of reference.

ACOUSTICS :

Acoustics deals with the study of sound and its transmission, production, and effects. Acoustics mainly involves the mechanical waves in gases, liquids, and solids, which include vibration, sound, ultrasound, and infrasound.

Option a) True, the energy associated with swinging a bat is a type of kinetic energy.

In the terms of physics, the energy that a body or a particle possesses due to its motion is said to the kinetic motion.

It is also defined as the work that is required in order to accelerate a body from rest to the stated velocity.

If work is done on an object by applying a net force on the body of that object, the speed of the object changes and it thereby gains kinetic energy.

The body after gaining this energy tries to maintain it until and unless its speed changes.

When the total debt ratio is 0.36, the debt-equity ratio is 0.5625.

The debt-to-equity ratio is a financial metric that shows how much debt and shareholder equity were utilized to finance the assets of a company. The ratio, often known as risk, gearing, or leverage, is closely related to leveraging. The debt-equity ratio serves as a gauge for how equally creditors and owners or shareholders contributed to the capital used by the company. The debt-equity ratio is the simple ratio of all long-term debt and equity capital in the company. The debt-to-equity ratio is calculated by dividing a company's total liabilities by the sum of its shareholders' equity. For the majority of businesses and industries, a desirable debt-to-equity ratio is around 2.0. A high debt-to-equity ratio shows that a business is using more market capital to finance its operations, whereas a low debt-to-equity ratio shows that the business is making better use of its assets and using less market capital. The debt-to-equity ratio is often higher in the capital industries.

Total Debt ratio = Debt/Asset

Hence, Debt=0.36*Total Assets

Assets = Debt*Equity

Hence Equity=(1-0.36)*Total Assets=0.64*Total Assets

The intersection of the sphere with the yz- plane will be (y -z)² + (z- 5)² =7

A sphere is can be define as , a geometrical object that has a three-dimensional analogue to a two-dimensional circle. In a very simple word, i.e. a sphere is the set of points that are all at the same distance r from a given point in three-dimensional space.

We are given that ,

The center of sphere = (h, k, l) = (-3,2,5)

The radius of sphere = (r) = 4

Then the formula of the equation of sphere with radius r and center (h, k, l) is given as,

(x- h)² +(y - k)² + ( z -l)² = r²

So that putting the value of center of sphere (h, k, l) and radius (r) in above equation then we get,

(x- (-3))² +(y - 2)² + ( z -5)² = 4²

(x +3 )² +( y - 2)² + ( z -5)² = 16

Therefore, we can write the equation of intersection of the sphere with the yz- plane and putting (x = 0) in above equation then,

(0 +3 )² +( y - 2)² + ( z -5)² = 16

( y - 2)² + ( z -5)² = 16 - 9

According to the given statement  the pulse pressure = 70mm Hg.

The correct option is 2.

Systolic, as well as diastolic blood pressure, as well as diastolic blood pressure, is divided to create pulse pressure. Mercury millimeters are used to measure it (mmHg).It represents the contractional force of the beating heart. Normal rested blood pressure is about 120/80 mmHg, which results in a pulse pressure of about 40 mmHg.

Diastolic blood pressure is subtracted from systolic blood pressure to determine pulse pressure. Age-related changes in the aorta and minor arteries' compliance result in elevated systolic pressure and decreased diastolic pressure, which raises pulse pressure.

Diastolic and systolic blood pressure differences are used to compute pulse pressure.

Gold foil experiment

Ernst Rutherford conducted the Gold Foil Experiment in which α particles (doubly charged Helium Atoms) were bombarded on a thin gold foil. This experiment led to the discovery of the nucleus.

1) Most of the particles passed through undeflected

⇒ this meant that most of an atom is empty space

2) Some Alpha particles were deflected by some small angles

⇒ Since alpha particles are positively charged species , they can only be deflected if there are some positively charged atoms present that would repulse these particles.

3) A few ( about 1/20000 particles) bounced back

⇒There is a heavy mass of positively charged species in the atom , and since the alpha particles bounced back , this mass of positively charged species must have been highly dense.

Therefore, from these observations and inferences Rutherford concluded that most of an atom is empty space and there is a mass of positively charged particles in the center of the atom called the nucleus which contains protons. The electrons revolve around this nucleus at high speeds.

The mass of the atom is concentrated in the nucleus and is very small in size , making it highly dense.
