The change or mutation in a segment of DNA after replication may lead to changes in the genotype, the traits of the organism and the proteins (option i, ii and iii).

A genetic mutation is any change in the nucleotide bases of the genome of an organism that may be associated with modifications in the phenotypic traits or features of the organism if this change alters the expression of a given gene that produces a particular protein.

Mutations may be neutral when they don't show an apparent effect on the phenotype of an organism such as occur in mutations located in intergenic regions.

Therefore, with this data, we can see that a genetic mutation may alter the proteins produced by an organism which has a direct effect on the phenotype by altering the structures that it is able to synthesize.

Answer: Velocity = v = 35 m/s

Explanation:

Kinetic energy of an object is defined as the energy possess by an object due to its motion. Kinetic energy K.E of an object is equal to the half of the mass of that object multiplied by square of the object's velocity.

Mathematically,

v = 35 m/s

The work done by a force in moving an electron through a positive potential difference of 2.0 x 10^6V can be calculated using the formula W = q x V, where W is the work done, q is the charge of the electron (which is 1.6 x 10^-19 C), and V is the potential difference. Plugging in the values, we get:W = (1.6 x 10^-19 C) x (2.0 x 10^6V)
W = 3.2 x 10^-13 J

Therefore, the amount of work that would have to be done by a force in moving an electron through a positive potential difference of 2.0 x 10^6V is 3.2 x 10^-13 J.
To calculate the work done in moving an electron through a positive potential difference, you can use the following equation:Work (W) = Charge (q) × Potential Difference (V)
The charge of an electron (q) is approximately -1.6 × 10^-19 Coulombs, and the potential difference (V) given in the problem is 2.0 × 10^6 V.
W = (-1.6 × 10^-19 C) × (2.0 × 10^6 V)
W = -3.2 × 10^-13 Joules
The negative sign indicates that the work done is against the direction of the electric field. Therefore, the work required to move an electron through a positive potential difference of 2.0 × 10^6 V is 3.2 × 10^-13 Joules.

When you walk, you are more likely to be able to walk at a constant velocity. Your walking speed varies as you walk in real-life scenarios, but you aim to maintain a steady pace or velocity. This is how you can keep track of time and distance traveled.

When you walk at a constant velocity, you move forward with a steady speed and direction. The velocity is defined as the rate at which an object's position changes with respect to time. When you walk, you typically aim to move forward with a constant velocity, which is the speed at which you walk and the direction you walk. In certain situations, a constant velocity is ideal, such as when you are traveling long distances and want to arrive at your destination at a certain time. To ensure that you walk at a constant velocity, you need to maintain a steady pace by keeping your stride consistent and avoiding unnecessary stops or changes in direction.

The work done on the shuttle will be negative, if its changes its circular orbit to a lower altitude.

The gravitational force between the object and the earth is balanced by the centrifugal force acting on the object during the circular motion. If a satellite of mass m, orbits around the earth in a circular path of radius R, then centrifugal force will be, mv²/R.

if the mass of the earth is M, and universal gravitational constant is G, then gravitational force between the earth and the satellite would be GMm/R².

mv²/R = GMm/R²

mv² = GMm/R

0.5mv² = 0.5GMm/R

But 0.5mv² = K = Kinetic energy of the satellite

K = 0.5GMm/R

So lesser the radius of the orbit, more the kinetic energy will be required for the satellite to orbit around the earth. So the work will be done by the orbit, in other words the work done on the satellite will be negative because it is done by the satellite.

The impact parameter that will give a deflection of 1 degree for an alpha particle of energy 7.7 MeV incident on a gold nucleus (Z = 79) is 9.38 x \(10^{-14}\) m.

The formula used to calculate impact parameter (b) is given by;

`b = [(z1*z2*\(e^2\))/(4πε0m\(v^2\))](cot(θ/2))`

Where, z1 and z2 are the atomic numbers of the interacting nuclei, e is the charge of an electron, ε0 is the permittivity of free space, m is the mass of the alpha particle, v is the velocity of the alpha particle, θ is the scattering angle.

The angle of deflection is 1 degree which is equal to 0.01745 radians. Given that an alpha particle of energy 7.7 MeV is incident on a gold nucleus (Z = 79).

The mass of the alpha particle (m) = 4u

Energy of the alpha particle (E) = 7.7 MeV

Charge of the alpha particle (e) = 2e

Atomic number of the gold nucleus (Z) = 79

Velocity of the alpha particle (v) can be calculated using the formula for kinetic energy given by;

`K = (1/2)\(mv^2\)

`Where, K is the kinetic energySubstitute the values to find v;`7.7*\(10^6\) eV = (1/2) * 4u * \(v^2\)``v = \(\sqrt{[(2*7.7*10^6)/(4*931.5*10^6)]`}\)

`v = 0.0132 m/s`

Now substitute all the known values in the formula for impact parameter;

b = [(z1*z2*\(e^2\))/(4πε0\(mv^2\))](cot(θ/2))`

= \([(79*2*1.6*10^{-19})^2/(4\pi *8.85*10^{-12}*4*3.14*0.0132*4*1.66*10^{-27})](cot(0.008725))\)`

Explanation:

The universe doesn't actually have an "end" in the conventional sense, according to current scientific theory. Instead, there doesn't seem to be a limit or edge that designates the "end" of the cosmos; rather, it appears to be endless in both space and time.

One of the key pieces of evidence for the infinite nature of the universe comes from observations of the cosmic microwave background radiation, which is a faint glow of radiation left over from the Big Bang. These observations show that the universe is very nearly the same in all directions, suggesting that it is homogeneous and isotropic on large scales and that there is no preferred direction or edge to the universe.

Observations of far-off galaxies provide additional proof, demonstrating that they are accelerating away from us at rates proportionate to their distance from us. Hubble's law, which asserts that the cosmos is expanding uniformly and without a center or edge, is well-known.

It is crucial to remember that our knowledge of the world is always changing and that fresh revelations may alter how we currently see the universe's structure and course of evolution.

n = 4 x 10¹⁸ photons

Explanation:

First, we will calculate the energy of one photon in the radiation:

\(E = \frac{hc}{\lambda}\\\\\)

where,

E = Energy of one photon = ?

h = Plank's Constant = 6.625 x 10⁻³⁴ J.s

c = speed of light = 3 x 10⁸ m/s

λ = wavelength of radiation = 567 nm = 5.67 x 10⁻⁷ m

Therefore,

\(E = \frac{(6.625\ x\ 10^{-34}\ J.s)(3\ x\ 10^8\ m/s)}{5.67\ x\ 10^{-7}\ m}\)

E = 3.505 x 10⁻¹⁹ J

Now, the number of photons to make up the total energy can be calculated as follows:

\(Total\ Energy = nE\\1.4\ J = n(3.505\ x\ 10^{-19}\ J)\\n = \frac{1.4\ J}{3.505\ x\ 10^{-19}\ J}\\\)

n = 4 x 10¹⁸ photons

Initial velocity of stone =  6 ms⁻¹

At the maximum height, the final velocity, v = 0

Acceleration of the stone, g = 9.8 ms⁻²

Time taken to reach maximum height = t₁

t₁ = v - u/g

since the stone is travelling upwards, g = -9.8 m/s⁻²

t₁ = 0 - 6/-9.8

t₁ = 0.61 s

Time take to fall from maximum height, t = 2 - 0.61s

Time take to fall from maximum height = 1.39s

where u = 0 m/s

v = 0 + 9.8 * 1.39

v = 13.6 m/s

Initial height of stone = Height of bridge, H

Time taken by the stone to fall down from height, H in water, t = 2s

Initial velocity of stone = 6 ms⁻¹

Acceleration of the stone, g = 9.8 ms⁻²

H =  -6 * 2 + 9.8 * 2² /2

H = 7.6m

Energy is defined in science as the ability to move matter or change matter in some other way.

The heat is exchanged when two different temperature objects come in contact. The energy gained by an ice block is 2.3 Joules.

Temperature is the degree of hotness and coldness of the object.

A 7g block of ice was added to a coffee cup full of 103.4 grams of water. The water had an initial temperature T₁ = 24.5 C and a final temperature T₂ = 19.2 C after all the ice had melted.

Heat lost by water = Heat gained by ice

Qgain = ms(T₂ -T₁ )

Substituting the value for mass of water m =103.4 g= 0.1034 kg , specific heat of water s = 4.18 kJ/kg and temperature values, we get

Qgain = 0.1034 x 4.18 x (24.5 - 19.2)

Qgain = 2.3 Joules

Thus, the energy gained by an ice block is 2.3 Joules.

Newton's law of universal gravitation states that every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Newton's Law of Universal Gravitation states that every object with mass attracts every other object with mass. The force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. The key equation for Newton's Law of Universal Gravitation is:
F = G * (m1 * m2) / r2.
where F is the gravitational force, G is the gravitational constant, m1, and m2 are the masses of the objects, and r is the distance between their centers.

This is a general law of physics derived from experimental observations, which Isaac Newton called inductive reasoning. It is part of classical mechanics and was developed in Newton's book Philosophiæ Naturalis Principia Mathematica ("Principles of Mathematics"), first published on July 5, 1687. When Newton presented Volume 1, he did not report to the Royal Society in April 1686. Robert Hooke claimed that Newton took the right back from him.

In modern language, the law states that each element of the group attracts all other elements of the group with a force acting along a line where the two elements intersect. The force is proportional to the product of the two groups and inversely proportional to the square of the distance between them.
