Answer:

The scattering angle is 0.80

Explanation:

As we know  

Wave length = h/mc (1-cos α) --1

W = mc^2

m = E/c^2

Substituting this in equation 1 we get  

Wavelength = hc/E (1-cos α)

Substituting the given values, we get -  

0.95*10^-9 = [(6.626 *10^-34 * 2.998 *10^8)/5.111*1000*1.6*10^-19} (1-cos α)

(1-cos α) = 1.14 *10^-10

cos α = 1- 1.14 *10^-10

α = 0.80

Explanation:

During phase shift, the substance's molecules' average kinetic energy remains constant.

Simply put, molecules move more quickly as kinetic energy rises. Nevertheless, molecules change phases when potential energy rises. The molecule changes phases as a result of an increase in potential energy.

In a phase change, matter moves from one state to another either by gaining energy through heat and entering a more energetic state, or by losing energy through heat and entering a state with lower energy.

The energy supplied during phase change is only used to separate the molecules; none of it is used to boost the kinetic energy of the molecules. Therefore, since the molecules' kinetic energy is constant, its temperature won't increase.

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.

Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.

Isotopes can be defined as the atom of an element that has the same number of protons but different number of neutrons. This ultimately implies that, the isotopes of an element have the same atomic number (number of protons) but different atomic mass (number of nucleons).

The isotope of an element is denoted by [tex] X_{Z}^{A} [/tex]

Where; X is the symbol of the element.

A is the atomic mass or number of nucleons.

Z is the atomic number or number of protons.

Hence, an atom with 29 protons and 36 neutrons is an isotope of copper because it has an atomic mass of 65, which corresponds with that of the chemical element known as copper with the symbol, Cu.

According to the kinetic theory of matter, changes in heat energy allow for phase transitions between solids, liquids, and gases.

When something is heated, the particles inside move faster and have more energy. When an object warms up, its atoms and molecules gain kinetic energy. When something is heated, its constituent atoms or molecules accelerate in their motion. Matter's kinetic energy can be quickly and easily increased.

When an object warms up, its atoms and molecules gain kinetic energy. The atomic or molecular motions of matter increase with temperature. Lifting a particle's kinetic energy is a breeze. When a substance absorbs heat, the inter-particle bonds in it weaken and break, resulting in a phase transition. If the particles aren't moving faster, there can't be any more heat.

Power is given at p=1.13 *10^(-5) throughout this period.

An electrical component that can store and release electric energy is a power capacitor. The device comprises of one or more pairs of plates that are connected to two terminals and allow the stored energy to be released into a circuit as needed. The plates are separated from one another by an insulating material (the dielectric). By removing the reactive power from the supply line, a capacitor aids in the improvement of power factor.

This is accomplished through the capacitor's storage of magnetic reversal energy. Power is defined as energy multiplied by the frequency of an operation. (a) Computation needs switching from one voltage (V 1) to another voltage (V 2) before most likely returning to a starting voltage (like V 1).

Answer:

the density of the mercury is 19.85 cm^3

Explanation:

Given that

The density of the mercury is 13.6g\cm^3

And, the mass of the mercury is 270

We need to determine the volume of the mercury

As we know that

density = mass ÷ volume

 13.6 g/cm3 =  270 g/ volume

volume = (270 g) ÷ (13.6 g/cm3)

= 19.85 cm^3

Hence, the density of the mercury is 19.85 cm^3

Answer:

this because the surface tension was lowered by using an impurity or rising the temp of the water

At his current velocity the sprinter will complete the 100.0-m dash in 28.53 s.

What is velocity?

Velocity is a vector quantity that describes the rate of change of an object's position. It is a measure of how fast an object is moving and in what direction. Velocity is measured in units of meters per second (m/s) or miles per hour (mph) and is often represented by the symbol "v".

We can use the equations of motion to calculate the time for the sprinter to complete the race.

First, we can use the equation:

v = u + at

to find the final velocity of the sprinter after accelerating for 20.0 m. Here, u is the initial velocity (which is 0 m/s since the sprinter is at rest at the start of the race), a is the acceleration of 3.20 m/s^2, and t is the time it takes for the sprinter to accelerate for 20.0 m.

v = 0 + (3.20 m/s^2)(t)

We know that the sprinter accelerates for 20.0 m, so we can use the equation:

s = ut + 1/2at^2

to find the time t:

20.0 m = (0 m/s)(t) + 1/2(3.20 m/s^2)(t^2)

t^2 = (20.0 m) * 2 / (3.20 m/s^2) = 12.5

t = sqrt(12.5) = 3.53 s

So the time it takes for the sprinter to accelerate for 20.0 m is 3.53 s.

Next, we can use the equation:

v = d/t

to find the time it takes for the sprinter to cover the remaining 80.0 m of the race at his final velocity. Here, d is the remaining distance of 80.0 m and v is the final velocity found before.

t = d/v = 80.0 m / (3.20 m/s) = 25.0 s

So the time it takes for the sprinter to cover the remaining 80.0 m of the race at his final velocity is 25.0 s

So the total time for the race is the sum of the time it takes to accelerate and the time it takes to cover the remaining distance at a constant velocity:

t = 3.53 s + 25.0 s = 28.53 s

Hence, at his current velocity the sprinter will complete the 100.0-m dash in 28.53 s.

The mass of water displaced when the mass of bird bone in water and air is given, is calculated to be 43.4 g.

Given that,

Weight of bird bone in air = True weight = 47 g

Apparent weight of the bird bone when submerged = 3.6 g

The equation for apparent weight is known to be,

Apparent weight = True weight - Buoyant force

Making Buoyant force as subject, we have,

Buoyant force = 47 g - 3.6 g = 43.4 g

F b = mw × g = (m wat - m air)× g

mw = m wat - m air = 47 g - 3.6 g = 43.4 g

Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix.

A nonsense mutation occurs in the DNA when a sequence changes itself and gives rise to a stop codon rather than a codon specifying an amino acid. The presence of the new stop codon results in the production of a shortened protein that is non-functional.

A nonsense mutation is also known as base substitution which results in a stop codon in such a position from where there was not one before, which causes the premature termination of protein synthesis and, more than likely, a complete loss of function in the finished protein.

So we can conclude that a nonsense mutation always causes a loss of amino acids.

C) With no friction, the final speed does depend on the steepness of the hill.

D) The final speed of the car if the height of the hill is 55 cm is 3.569 m/s.

Given that there is no friction considered. Thus, the total energy of the system can be considered as conserved.

Thus, sum of kinetic and potential energy will be constant.

K = U

mu 2   = mgh ......................................(1)

m = mass of object

v = speed of object

g = acceleration due to gravity = 9.8 m/s2

h = height of object with respect to a reference position

Thus for an object at a height from ground, will have its potential energy converted to kinetic energy during it's descent.

(A) from (1)

mv2 = 2mgh

Thus,   v2 = 2gh

            v = (2gh)1/2

this, is the velocity of an object from conservation of energy.

(B) with no friction, the enrgy is taken to be conserved. from the answer of (A), we know,

v = (2gh)1/2.

clearly this equation doesn't depend on mass.

thus, final speed doesn't depend on the mass.

(C) Given height of hill , h = 65cm = 0.65 m

from (1),    v = (2gh)1/2.

the potential energy of car at the hill top = mgh

this potential energy gets entirely converted to kinetic energy at the bottom of hill due to conservation of energy. Thus

v = (2 x 9.8 x 0.65)1/2

The law of conservation of momentum states that the momentum of a system is equal and conserved before and after collision. Therefore, the final momentum of the system is 513 kgm/s.

The law of conservation of momentum states that, for two or more bodies which are present in an isolated system that are acting upon each other, their total momentum remains constant in the system unless an external force is applied on them. The expression for conservation of momentum is:

m₁ u₁ + m₂u₂ = m₁v₁ + m₂v₂

where, m₁ = mass of one object,

m₂ = mass of another object,

u₁ and u₂ are the initial velocities of objects,

v₁ and v₂ are the final velocities of objects.

Here, m₁ = 95kg, m₂ = 120kg

u₁ = 5.4m/s, u₂ = 0m/s (at rest)

m₁ u₁ + m₂u₂ = m₁v₁ + m₂v₂

95 × 5.4 + 120 × 0 = 95 × v₁ + 120 × v₂

When the frequency of a standing wave set up in a pipe (with both ends open) first harmonic is 300 Hz, the length of pipe is 0.567 metres.

Therefore the answer is 0.567 m.

The speed of sound in air is approximately 340 m/s, and the wavelength of the first harmonic of a standing wave in an open pipe is twice the length of the pipe. Therefore, if the frequency of the first harmonic is 300 Hz, the wavelength can be calculated as:

wavelength = speed of sound / frequency

wavelength = (340 m/s) / (300 Hz)

The length of the pipe can be calculated as half the wavelength:

L = wavelength/2

L = (340 m/s) / (2×300 Hz)

L ≈ 0.567 m
