The Quantum theory doesn't prove that consciousness moves to another universe at death. So, the statement is b) false.

The quantum theory of consciousness argued that the brain's nervous system forms a complex network of consciousness that it produces and should follow the rules of quantum mechanics, the theory that governs how tiny particles like electrons move. They argue that this can explain the mysterious complexity of human consciousness. The idea that quantum effects are necessary for consciousness to function is still in the realm of philosophy. Penrose suggests that it is necessary, but other theories of consciousness do not. argued that it should obey the rules of quantum mechanics and quantum theory.

One kind of contact force is friction. It exists between surfaces that are in contact with one another.

Contact force: What is it?

Objects in interaction with each other exert a force on one another known as contact force. The point of immediate contact between two objects is where the contact force acts. This force may be brief in the form of such an impulse or it may be continual as a continuous force.

What, by way of example, is contact force?

A force which acts at the point where two objects come into touch is known as a contact force. Examples of contact stress include kicking a ball and pushing an car up a hill.

+2 charge on an ion means the given ion has 2 extra electrons.

In chemistry,

We often use symbols like plus (+) and minus (-) which is usually written in the superscript of the ions.

As + is given when the given ions have extra electrons.

As we know,

Every atom/ ion needs to complete an octet in its outermost orbit for becoming stable.

So, if in any of the ion +2 is written it means that the given ions have 2 extra electrons present in their outermost orbit and once the ion release those 2 extra electrons it becomes cationic in nature.

Similarly, if -2 is written it means that the given ions have 2 deficit electrons in their outermost orbit, so for becoming cationic the ions need 2 electrons.

Graph 3 represents the correct graph between the gravitational force and two point masses.

Let the gravitation force is taken as F and the distance between two point masses is taken as r.

We know the relation between the force, two point masses and distance between masses as,

F = (G m₁ m₂)/r²

where, G is the gravitational constant

m₁ and m₂ two point masses

r is the distance between them

From the above relation, it is clear that, F is inversely proportional to r².

So, when F increases, r² decreases.

The cause of our solar system beginning to form is A: "a large cloud of dust and gas began to contract under the force of gravity."

Our solar system evolved from a dense cloud of interstellar gas and dust some 4.6 billion years ago. The cloud collapsed, probably as a result of the shockwave from a nearby exploding star known as a supernova. When this dust cloud collapsed, it created a solar nebula, which is a spinning, swirling disc of material.

It means that the formation of our solar system began around 4.6 billion years ago with the gravitational collapse of a small part of a larger molecular cloud.

By measuring the length of the pendulum and the period of oscillation at different locations, you can compare the value of g at those locations and see how it varies.

Generally, To determine the acceleration due to gravity using a simple pendulum, you will need to measure the length of the pendulum and the period of oscillation of the pendulum. The period of oscillation is the time it takes for the pendulum to complete one full swing.

To measure the period of oscillation, you can use a stopwatch or a timer to measure the time it takes for the pendulum to swing back and forth a certain number of times (such as 10 swings). The longer the pendulum, the longer the period of oscillation will be.

Once you have measured the length of the pendulum and the period of oscillation, you can use the following equation to calculate the acceleration due to gravity:

Energy in terms of Joules = 1956.50 GJ is the answer.

Energy generation by the Power plant (on annual basis) is given as: -

A.  When heat recovery feature is Present

E = (M * HHV * C * ηc * 365) / 3600 watt – hr         ------------- equation (i)

B.  When heat recovery feature is not present

E = (M * LHV * C * ηc * 365) / 3600 watt – hr        ------------- equation (ii)

Here,

 M = Mass of Pellets consumed per day (Kg/day)

 HHV = Higher Heating Value of Biomass (J/Kg)

 LHV = Lower Heating Value of Biomass (J/Kg)

 C = Capacity factor {Plant running this % time in a day}

 ηc = Conversion efficiency

 Joule to watt – hr conversion factor

 1 Joule = 1 /3600 watt – hr

Given:

 M = 1.3 * 106 Kg/day;

 HHV = 19.9 * 106 J/Kg;

 LHV = 17.4 * 106 J/Kg

 C = 56% = 0.56

 ηc = 37% = 0.37

Heating Recovery feature ---> Present

As heating recovery feature is present so eq. 1 will be used

Now, putting corresponding given values in Eq. 1 to get the value of E.

E = (M * HHV * C * ηc * 365) / 3600

E = (1.3 * 106 * 19.9 * 106 * 0.56 * 0.37 * 365) / 3600

E = (1956.496 * 1012) / 3600

E = 543.47 Gwh

Energy in terms of Joules = 543.47 * 3600

Energy in terms of Joules = 1956.50 GJ

Energy Generation (E) by the power plant (on annual basis) = 543.47 Gwh (Giga Watt – hour)

The magnetic flux through the loop is 0.098 Wb.

Magnetic flux (often symbolized Φ), is the measure or amount of magnetic field B passing through a certain cross-sectional area, for example, a coil of wire (this is also often called "magnetic field density"). The unit for magnetic flux in International Units is the weber (Wb) (Weber is a derived unit from the volt-second).

Magnetic Flux Formula:

                                   ∅ = B A cos α

Where:

∅ = magnetic flux (Wb)

B = magnetic field (T)

A = cross-sectional area (m)

α = angle between B and the normal plane

On the given question:

B = 0.50 T

r = 0.25 m

α = 0° ⇒ because it is in a flat plane

A = πr²

Then substitute:

∅ = B A cos α

∅ = 0.50 x π (0.25)² x cos0°

∅ = 0.50 x 3.14 (0.0625) x 1
