For Piaget cognitive development was the gradual reorganization of mental processes as a result of biological maturation and environmental experience. Children make sense of the world around them and experience discrepancies between what they already know and what they discover around them.

Fundamentally Piaget believed that man could make sense of the world on his own. From a theological point of view, he was a psychological constructivist believing that learning is caused by a mixture of two processes for him assimilation and adaptation. Piaget supported the idea that children think differently than adults and his research identified several important milestones in children's intellectual development.

Oxygen is essential for cellular respiration, which is the process by which cells convert food molecules (such as glucose) into energy in the form of ATP (adenosine triphosphate). Cellular respiration occurs in the mitochondria of cells and is a complex series of metabolic reactions that requires oxygen as the final electron acceptor in the electron transport chain.

Without oxygen, cellular respiration cannot proceed beyond glycolysis, which is the first step in the process. Glycolysis breaks down glucose into two molecules of pyruvate and produces a small amount of ATP. However, this process is not very efficient, and it cannot sustain cellular activity for very long.

The moment of inertia of the flat square is MA²/6

The moment of inertia of a body is a property of the body which shows its ability to ritate about an axis.

To find the moment of inertia of the flat square through its center of mass, we know that the moment of  inertia of  a rectangular slab is given by

I = M(a² + b²)/12 where

Now, for a flat square a = b. so,its moment of inertia is I = M(a² + b²)/12

I = M(a² + a²)/12

= 2Ma²/12

= Ma²/6

Now for the given flat square, we have that

So, substituting these into the equation of moment of inertia for the flat square, we have that

The moment of inertia of the flat square is given by

I = Ma²/6

I = MA²/6

So, moment of inertia is MA²/6

The wave speed remains the same, but the wavelength will decrease as the frequency increases.

The speed of a wave is determined by the product of its wavelength and frequency. This relationship is described by the formula:

wave speed = wavelength x frequency

In this case, the given wavelength is 0.5 m and the frequency is 10 Hz. Therefore, the initial wave speed can be calculated as:

wave speed = 0.5 m x 10 Hz = 5 m/s

If the frequency of the wave increased, the wave speed and wavelength would change according to the following relationship:

wave speed = new wavelength x new frequency

However, the wavelength and frequency are inversely proportional to each other. This means that as the frequency increases, the wavelength will decrease, and vice versa. This relationship is described by the formula:

new wavelength = old wavelength x (old frequency / new frequency)

Let's say the frequency of the wave increases to 20 Hz. Using the above formula, the new wavelength can be calculated as:

new wavelength = 0.5 m x (10 Hz / 20 Hz) = 0.25 m

Now that we know the new wavelength, we can calculate the new wave speed using the wave speed formula:

new wave speed = new wavelength x new frequency = 0.25 m x 20 Hz = 5 m/s

As you can see, the wave speed remains the same, but the wavelength decreases as the frequency increases.

In the round robin scheduling algorithm, time quantum is specified. As part of a theory that contends that time is not continuous, a chronon is a discrete and indivisible "unit" of time that is proposed.

A preemptive scheduler permits a certain process to operate for a brief period of time known as a quantum (or time slice). The process is put back in the ready queue after this amount of time and another one is put into the run state (i.e., the scheduler ensures that the processes take turns to run). Round Robin Scheduling fixes the time quantum before scheduling the processes such that no one process receives more CPU time than one time quantum at a time. The response time of the processes is too long if time quantum is too large, which could not be acceptable in an interactive environment.

Voltage depends on the amount of resistance, current according to the Ohm's law, and, by definition, is the measurement of electrical pressure.

According to the Ohm's Law,  the current through a conductor between two points is directly proportional to the voltage across the two points.

Mathematically,

V ∝ I

V = IR

where, R is the resistance of the conductor and I is the current flowing in the conductor. So, the voltage depends on the amount of resistance and current.

Also, Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.

vi = 0

a = 5 m/s^2

vf=?

Formula

KE = 1/2 m v^2

d = vi * t + 1/2 a t^2

a = (vf - vi)/t

Solution

The final KE = 0 because the final velocity = 0 (The concrete wall saw to that).

Second formula

d = vi*t  + 1/2 a t^2

20  = 0 + 1/2 * 5 * t^2

40 = 5*t^2                         Divide by 5

40/5 = t^2

8 = t^2

2√2 = t

Third formula

5 = (vf - 0)/2√2                Multiply by 2√2

5* 2√2 = vf

10√2= vf

First formula

KE = 1/2 m * (10√2)^2

KE = 1/2 1450 * 100*2

KE = 1450 * 100              2 and 1/2 cancel out.

KE = 145000

This means that the change in KE is 145000 Joules or 145 kJ

It has to do with impulse or force. Just how the sheet has no volume. There is no sufficient impulse to crack the shell.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

The sagging sheet gives the impact with the egg additional time, which prevents the egg from breaking when it is hurled against it. This lessens the force the egg would have applied to the wall had it been flung at it.

The height of the jump having a mass of 67kg with the vertical velocity of 6.4m/s is 2.089m.

Potential energy is defined as the energy stored in an object or system by virtue of its position or arrangement of parts while kinetic energy is defined as the energy of the moving particles of an object or system.

Potential energy is represented as :

P.E.= mgh

Kinetic energy  is represented as :

\(K.E.= 1/2mv^2\)

where, m = mass of the object

h= height

v= velocity

g= acceleration due to gravity which is \(9.8m/s^2\)

For above given example,

m= 67kg, v= 6.4m/s

we first find out Kinetic energy,

K.E.=\(\frac{1}{2} 67* (6.4)^2\)= 2744.32/2= 1372.16 J

As we know, K.E.= P.E.

So, P.E.= 1372.16J = mgh

1372.16= 67* 9.8* h

Pressure gauge is located at the bottom of the container thus, the depth of the mercury = 11.05 cm

Pressure refers to the force applied on a unit area of a surface. It works parallel to the pressure-applied surface. Pressure = force multiplied by the area on which it operates. The stronger the power, the smaller the area.

Given that,

pressure exerted by block (\(P_{B}\))= weight / cross-section area of block

\(P_{B}\) = (1 ×9.81) ÷ (10 × 10⁻⁴)

     = 9810 Pa

Now, pressure at bottom of container is given as:

\(P_{Bottom}\) = \(P_{B}\) + ρ × g × h + ρ₁ × g × h₁  

[ ρ = density of water,

ρ₁ = density of Hg,

h = height of water and

h₁ = height of Hg ]

Thus, 27000 = 9810 + (1000 × 9.81 × 0.25) + (13600 × 9.81 × h₁)

h₁ = 14737.5 ÷ 133416

h₁ = 0.1105 m

h₁ = 11.05 cm

The box accelerates to the right due to the applied force of 35 N in the +x direction.

Newton's second law states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. In this case, the net force acting on the box is 35 N in the +x direction, and its mass is 15 kg. Therefore, we can calculate the acceleration using the formula:

acceleration = net force / mass

acceleration = 35 N / 15 kg = 2.33 m/s² (rounded to two decimal places)

Since the box is not accelerating up or down, we can conclude that the force applied is only causing the box to accelerate in the horizontal direction.

Other forces such as gravity and friction are not considered in this scenario. Thus, the 15 kg box will experience an acceleration of approximately 2.33 m/s² in the +x direction due to the applied force of 35 N.
