Answer:

Speed is a scalar quantity, that is, it is a number and indicates how fast (or slow) one travels at any given time.

Velocity is a vector quantity, this means that it has magnitude and direction, that is, how fast an object travels and its where its going (speed + the direction in which the object moves).

Acceleration is the ratio of the velocity change over the time interval in which this velocity change occurred. Acceleration as well as velocity is a vector quantity so it is made up of magnitude and direction.

The differences between these three quantities are important for the description of the movement. In the case of speed and velocity, its difference lies in the fact that velocity indicates the direction in which the movement is taking place (and speed is only a number), which in many physical phenomena the direction of movement is an important property. And the difference between acceleration and velocity is that acceleration instead of a velocity indicates a change in velocity (either in magnitude, direction or both), which tells us how fast a velocity will increase or decrease over time.

If the atomic radius of gold is 0.144 nm, then the  volume of its unit cell in cubic meters is  6.7847 × 10⁻²⁹ m³.

A chemical element's atomic radius, which is typically the average or typical distance between the nucleus's centre and the outermost isolated electron, serves as a gauge for the size of its atom. There are numerous non-equivalent definitions of atomic radius because the boundary is not a clearly defined physical entity.  

Van der Waals radius, ionic radius, metallic radius, and covalent radius are the four most frequently used definitions of atomic radius. The atomic radius is typically measured in a chemically bonded state because it is difficult to isolate individual atoms to measure their radii separately.  

However, theoretical calculations are easier when considering isolated atoms. A variety of definitions result from the dependencies on environment, probe, and state.

Atomic radius of gold (r)  = 0.1442nm

                                         = 0.1442 × 10⁻⁹m

Gold is FCC then

FCC unit cell  side a        = \(2\sqrt{2r}\)

Unit of the volume v        = a³ = ( \(2\sqrt{2r}\) )

Unit cell volume (V)         = 16\(\sqrt{2\times r^{3}\)

volume of unit cell           =6.7847  × 10⁻²⁹ m³

Thus, If the atomic radius of gold is 0.144 nm, then the  volume of its unit cell in cubic meters is  6.7847 × 10⁻²⁹ m³.

Force of air and gravitational force are acting on the ball when launched from the slingshot.

When a ball is launched from a slingshot, during its travel force of air as well as gravitational force are acting on the ball because there is air which moves opposite to the motion of a ball whereas the force of gravity attracts the ball downward.

The force of air slows down the motion of the ball while on the other hand, the force of gravity brings the ball to the ground due to attraction. If these two forces are not present then the ball continues its motion forever so we can conclude that force of air and force of gravity are acting on the ball when launched from the slingshot.

The correct expression for the rotational inertia of the spherically shaped object is \(\(\text{c) } 3.6m^5\)\).

In the given scenario, the students determine that the radius of the object is given by \(\(r = km^2\) with \(k = 3\, \text{m/kg}^2\)\). To calculate the rotational inertia of the object, we need to use the formula for rotational inertia of a spherical object, which is given by \(\(I = \frac{2}{5}mr^2\)\), where m is the mass of the object and r is the radius.

Substituting the given expression for r in terms of m, we have \(\(I = \frac{2}{5}m(km^2)^2\)\). Simplifying this equation, we get \(\(I = \frac{2}{5}mk^2m^4\)\).

Substituting the value of \(\(k = 3\, \text{m/kg}^2\)\), we have \(\(I = \frac{2}{5}(3\, \text{m/kg}^2)^2m^5\)\), which further simplifies to \(\(I = \frac{2}{5} \times 9 \, \text{m}^2/\text{kg}^2 \times m^5\)\).

Finally, multiplying the constants, we get \(\(I = 3.6 \, \text{m}^2/\text{kg}^2 \times m^5\)\), which corresponds to option c) \(3.6 \(m^5\)\).

Therefore, the correct expression for the rotational inertia of the object is \(3.6 \(m^5\)\).

Answer:

a) Ffloor = 616.56[N]

b) Ffloor = 484.16 [N]

Explanation:

In order to solve this problem, we must first make a free body diagram. In this free body diagram include forces, as well as acceleration.

Then after the free body diagram, we perform a force analysis by means of Newton's second law, where the upward forces and even the upward acceleration will be taken as positive.

ΣF = m*a

where:

F = force [N] (units of Newtons]

m = mass [kg]

a = acceleration [m/s²]

g = gravity acceleration = 9,81 [m/s²]

a)

\(F_{floor} -m*g = m*a\)

\(F_{floor} -(56*9.81)=56*1.2\\F_{floor}= 616.56[N]\)

b) Using Newton's second law we have.

\(F_{floor}-m*g= -m*a\\F_{floor}=-m*a+m*g\\F_{floor} = -(56*1.2) + (56*9.81)\\F_{floor} = 484.16 [N]\)

When a bicyclist is pedaling up a hill, it is a form of potential energy. The correct option is option potential energy.

An object's position or configuration in relation to other things might provide it potential energy. The potential energy in this situation is gravitational potential energy.

Because they are being lifted against gravity as they ascend the hill, the cyclist gains gravitational potential energy. The potential energy of the cyclist increases as they ascend.

The potential energy will be transformed into kinetic energy once the cyclist begins pedaling or moving downward.

As a result of their increased height above the ground, cyclists are building up potential energy as they bike up a hill. They gain speed as they cycle downhill, transforming that potential energy into kinetic energy.

**Elliptical galaxies can indeed be formed through mergers between spiral galaxies.**

When two spiral galaxies interact and eventually merge, their gravitational forces can distort the shapes of the galaxies, leading to the formation of an elliptical galaxy. During the merger process, the gas, dust, and stars from both galaxies mix and redistribute, causing the resulting galaxy to lose its well-defined spiral structure and adopt a more spheroidal or ellipsoidal shape.

The merger process can trigger intense star formation and produce tidal interactions that disrupt the spiral arms, leading to the formation of a centrally concentrated, elliptical-shaped galaxy. The resulting elliptical galaxy will exhibit characteristics such as a smooth, featureless appearance, a lack of distinct spiral arms, and a generally older stellar population compared to spiral galaxies.

Observations and computer simulations of galaxy interactions and mergers provide strong evidence for the formation of elliptical galaxies through the merging of spiral galaxies. These mergers play a significant role in shaping the structure and evolution of galaxies throughout the universe.

The false statement is B) Homolytic bond cleavage yields neutral radicals in which each atom gains one electron.

In homolytic bond cleavage, each atom retains one electron from the shared pair of electrons, resulting in the formation of two neutral radicals, where each atom retains its original number of electrons.

No atoms gain or lose electrons in this process.

In a homolytic bond cleavage, a covalent bond is broken, and the shared pair of electrons is split equally between the two atoms involved in the bond.

This results in the formation of two neutral radicals, with each atom retaining one of the electrons from the shared pair.

A radical is a chemical species characterized by the presence of an electron that is unpaired, meaning it does not have a partner electron with which it forms a complete pair. When a covalent bond is homolytically cleaved, each atom involved in the bond gains one electron, resulting in the formation of two radicals.

These radicals are highly reactive due to the presence of the unpaired electron, which makes them prone to participate in further chemical reactions.

It's important to note that in homolytic bond cleavage, there is no transfer of electrons from one atom to another.

Instead, the bond is broken in a way that allows each atom to retain one of the electrons, leading to the formation of two neutral radicals.

Therefore, statement B, which suggests that each atom gains one electron, is false.

The point on the y-axis where the magnetic field is zero can be determined by applying Ampere's law, which states that the sum of the magnetic field contributions from currents passing through a closed loop is proportional to the total current passing through the loop.

In this case, we have two wires carrying currents in opposite directions. The magnetic field at a point on the y-axis due to each wire can be calculated using the formula:

B = (μ0 / 2π) * (I / r),

where B is the magnetic field, μ0 is the permeability of free space (4π × 10^(-7) T·m/A), I is the current, and r is the distance from the wire to the point of interest.

Let's consider a point on the y-axis at a distance y from the x-axis. The magnetic field contributions from the two wires can be calculated as follows:

B1 = (μ0 / 2π) * (i1 / r1) = (4π × 10^(-7) T·m/A / 2π) * (45 A / r1),

B2 = (μ0 / 2π) * (i2 / r2) = (4π × 10^(-7) T·m/A / 2π) * (35 A / r2),

where r1 is the distance between the first wire and the point on the y-axis, and r2 is the distance between the second wire and the same point on the y-axis.

To find the point on the y-axis where the magnetic field is zero, we set B1 + B2 = 0 and solve for y:

(4π × 10^(-7) T·m/A / 2π) * (45 A / r1) + (4π × 10^(-7) T·m/A / 2π) * (35 A / r2) = 0.

Simplifying the equation, we have:

(45 A / r1) + (35 A / r2) = 0.

From this equation, we can see that for the magnetic field to be zero, the sum of the magnetic field contributions from the two wires must cancel each other out. The specific value of y where this occurs depends on the values of r1 and r2, which are the distances from the wires to the point on the y-axis.

Given that y1 = 2 cm and y2 = 11 cm, we can calculate r1 and r2 as follows:

r1 = √((x^2 + y1^2)) = √((0^2 + 0.02^2)) ≈ 0.02 m,

r2 = √((x^2 + y2^2)) = √((0^2 + 0.11^2)) ≈ 0.11 m.

Now, substituting these values into the equation above, we have:

(45 A / 0.02 m) + (35 A / 0.11 m) = 0.

Simplifying further, we find:

2250 A/m + 318.18 A/m = 0,

2570.18 A/m = 0.

Since it is not possible for the sum of positive values to equal zero, there is no point on the y-axis where the magnetic field is exactly zero in this scenario.
