Answer:

✨Hello mark as branlist Identify the physical principles involved by listing the givens and the quantities to be calculated

Explanation:

The de Broglie wavelength for a particle== 0.92 ×10⁻³⁴m.

de broglie wavelength is the wavelength associated with particle of mass m moving with velocity v.

p= h/ λ

where, p -is  the momentum of the atom;

h- Planck's constant - 6.626×10⁻³⁴ m²kg s⁻¹

λ- wavelength;

Momentum can be expressed as

p=m×v

where , m is  the mass of the particle;

v - the speed of the particle.

so,

λ = h/(m×v)

= ( 6.626×10⁻³⁴ m²kg s⁻¹)/(1.2kg × 6.0 m/s)

= (6.626×10⁻³⁴ m²kg s⁻¹)/7.2

= 0.92 ×10⁻³⁴ m

The radius of curve that a car goes around that is banked at an angle of 32.6° is 69 m

R = v² / g tan θ

R = Radius of the curve

v = Velocity

g = Acceleration due to gravity

θ = Banked angle

R = 20.8² / ( 9.8 * tan 32.6° )

R = 432.64 / ( 9.8 * 0.64 )

R = 432.64 / 6.27

R = 69 m

A banked surface is a surface that is sloped upwards on the outer side of a curve. In race car tracks, the banked angle is usually 12° to 36°.

The average force acting on the ball is biggest in the with the cement floor case 2 when in the collision the ball bounce back to half of its initial height.

It is asked that in which case the average net force on the ball is highest.

According to impulse-momentum theorem,

Impulse I = F.Δt

where, F is the net average force and Δt is the time of contact during the collision.

In the case of collision with the rubber piece the time of contact of the ball and the ball increases by large amount while in the case of cement floor the time of contact is very very less.

The change in momentum which is equal to the Impulse is also biggest in the case of cement floor because the transfer of kinetic energy of the ball in the case of cement floor will be almost immediate.

Answer: Substance 3 is liquid at room temperature

Explanation: The common room temperature is assumed to be 20-22°C, we need to find the substance that will be in liquid state in that temperature.

For Substance 1, the boiling point is -195.975°C, and hence at room temperature, it would be in vapor phase and all liquid would have turned to gas.

For Substance 2, the boiling point is 3.85°C, and hence at room temperature, it would be in vapor phase and all liquid would have turned to gas in this case too.

For Substance 3, the boiling point is 77.85°C, and melting point is -108.15°C, hence at room temperature, it would be in liquid state.

For Substance 4, the melting point itself is 1800°C, due to which at room temperature it would be in solid state.

In order for the electrons to emit photons and leave the ground state, the heat produced by the electricity must be present.

The electron is a subatomic particle with a negative one elementary charge electric charge. Due to their lack of components or substructure, electrons, which are part of the lepton particle family's first generation, are typically thought to be elementary particles.

The electromagnetic force is carried by a photon, an elementary particle that is a quantum of the electromagnetic field and includes electromagnetic radiation like light and radio waves. Since photons have no mass, they always move at the 299792458 m/s speed of light in a vacuum.

A characteristic of an object in motion that it possesses as a result of its mass and motion and which, generally speaking, equals the product of the object's mass and velocity: a feature of an object in motion that determines how long it will take to bring it to rest when subjected to a constant force.

When a certain force is applied for a certain amount of time, a mass's velocity changes.

The following equation expresses this:

Eq. 1: Mass * Force * Time (Final velocity – Initial velocity)

Mass times speed equals momentum.

Both the average and instantaneous velocities well be same over the given interval if the acceleration is zero.

Instantaneous velocity is the rate of differential change of displacement with respect differential change in time. Mathematically -

v = dx/dt

Given is the acceleration of a school bus over a given time interval as zero.

For acceleration over a given time interval to be zero, it must be ensured that the the velocity of the object should remain constant. Mathematically-

a = (v - u)/(t₂ - t₁)

For acceleration [a] = 0, v = u. Therefore -

a = 0

The instantaneous velocity for zero acceleration between the time interval t₁ to t₂ will be equal to initial velocity only -

dx/dt = u          

This will be the instantaneous velocity and is equal to (u) at any instant.

Now -

dx = u dt

Integrating both sides, we get -

∫dx = ∫u dt

x = ut

Therefore, the average velocity will be =

v(avg) = x/Δt = ut/Δt

Now -

t = Δt for any specific time interval. Therefore -

v(avg) = ut/t = u

This is the average velocity and it is equal to (u).

Formula :-

Percentage error = V₀ - Vᵃ/ V₀ × 100%

V₀ = observed value, given = 3486 km

Vᵃ = accepted value, given = 3486 km

Hence, there is no difference between observed value and accepted value. So the Percentage error is zero.

Percentage error compares an estimate to a correct price and expresses the distinction among them as a percentage. This statistic permits analysts to recognize the scale of the error relative to the real fee. it's also known as percent errors and % error.

Percentage error is the difference between a measured or experiment value and an frequent or known price, divided by way of the known price, accelerated by using 100%.

The center of mass of the three mass system is at 83cm

A position relative to an object or set of objects is known as the center of mass. It is the system's average location, weighted by the mass of each component.

Given the mass of the meter stick is:

M = 0.5kg.

Since the meter stick is uniform, the center of mass of the meter stick is at 50cm or 0.5m.

Let the distance of the meter stick's center of mass from 0cm be x1. Then x1 = 0.5m.

Now a mass m2 = 1kg is attached at 50cm mark.

So the distance of m2 from 0cm is x2 = 50cm = 0.5m.

Similarly a mass m3 = 3kg is attached at the every end or 100cm mark. So the distance of m3 from 0cm is x3 = 100cm = 1m.

Now the position of the three mass system from 0cm is given by,

[tex]X_{CM}=\frac{Mx_{1}+m_{2}x_{2}+m_{3}x_{3}}{M+m_{2}+m_{3}}X_{CM}=\frac{0.5\times 0.5+1\times 0.5+3\times 1}{0.5+1+3}=\frac{3.75}{4.5}=0.83m = 83cm[/tex]
