1.496E+11 metres, 1.4960E+13 centimetres, and 1.4960E+8 kilometres are all equivalent to one astronomical unit (au). The average distance between the sun and the earth serves as the basis for this peculiar unit.

The distance between any two places in space is equal to the length of the straight line connecting them, which is also the shortest path. This is the usual conception of distance in classical physics, especially in Newtonian mechanics. The straight-line distance is mathematically known as the Euclidean distance in two- and three-dimensional space. The physical concept of distance is employed in physics to explain how far an object has moved. Distance is a scalar quantity.

1) The ratio of density of A to density of B is 3/2.
2) The ratio of volume of A to the volume of B is 1/3.

How closely a material is packed together is determined by its density. As the mass per unit volume, it is referred to. D or is the symbol for density. Formula for Density = m/V, where is the density, m is the object's mass, and V is its volume.

Given:

Weight of A block = 12 N

Apparent weight of A block = 8 N

Weight of B block = 20 N

Apparent weight of B block  = 12 N

Given is a relationship between apparent weight and original weight.

W' = W -B --- (1)

B = W dis liq - ρ liq V obj ---(2)

For block-A :

From equations (1) and (2),

W' = W  - ρt V

Substitute the given values,

8 = 12 - ρt V

ρt V = 4 ---(3)

For block-B :

From equations (1) and (2),

W' = W  - ρt V

12 = 24 - ρt V

ρt V = 12 ---(4)

From equations (3) and (4)

ρt VA/ρt VB = 4/12

ρt VA/ρt VB = 1/3

As a result, the ratio of volume of A to the volume of B is 1/3.

From given weights of A block  and B block,

[tex]W_A}[/tex]/[tex]W_{B}[/tex] = 12/24 ---(5)

weight of an object in terms of volume and density can be written as,

W = ρ Vg

So, equation (5) written as,

The amount of cubic metres that one kilogramme of matter takes up is known as the specific volume. It is the reciprocal of density and the ratio of a substance's volume to mass. In other words, specific volume is inversely related to density. Any state of matter may be measured or calculated for specific volume, but calculations involving gases are where it is most frequently applied.

Though it can also be expressed in terms of millilitres per gramme (mL/g) or cubic feet per pound (ft³/lb), the standard unit for specific volume is cubic metres per kilogramme (m³/kg).

Dialogic communication is the open sharing of ideas in an atmosphere of respect (in order to achieve understanding between the speaker and listener(s).

Dialogic communication is a method of communication that promotes dialogue between a speaker and their audience. In presenting their ideas to an audience, dialogic communication encourages speakers to be assertive (calm, respectful, and open). The dialogic theory is founded on three guiding principles: Monologue is less natural than dialogue. Meaning is found in people, not words. Perceived meanings are influenced by contexts and social situations (Bakhtin, 2001a; Bakhtin, 2001b). Mutuality, propinquity, empathy, risk, and commitment are the five principles underlying dialogic theory (Kent & Taylor, 2002). Mutuality is defined by an orientation toward inclusion or collaboration, as well as a spirit of mutual equality. Mutuality has two characteristics: collaboration and a spirit of mutual equality.

8.3 m/s is the terminal velocity of the squirrel can be calculated using the equation for terminal velocity and 10.8 m/s is the velocity of a 50.0 kg person hitting the ground.

What is velocity?
Velocity is a measure of the speed of an object's motion in a particular direction. It is a vector quantity, meaning it has both magnitude and direction. Velocity is usually measured in meters per second (m/s).

The terminal velocity of the squirrel can be calculated using the equation for terminal velocity of an object in a fluid, which is given by Vt = (2×m×g)/(ρ×Cd×A). Here, m is the mass of the object, g is the acceleration due to gravity, ρ is the density of the fluid, Cd is the drag coefficient, and A is the reference area of the object. The drag coefficient for a horizontal skydiver is 0.8, and the density of air is 1.225 kg/m^3. Therefore, the terminal velocity of the squirrel can be calculated as Vt = (2×500×9.8)/(1.225×0.8×895) = 8.3 m/s.

The velocity of a 50.0 kg person hitting the ground can be calculated using the equation for the velocity at the end of a fall, which is given by Vf = sqrt(2×g×h). Here, g is the acceleration due to gravity and h is the height of the fall. Therefore, the velocity of the person hitting the ground can be calculated as Vf = sqrt(2×9.8×5.6) = 10.8 m/s.

A bar rotates horizontally about its center, reaching a maximum angular velocity in 6 complete rotations from rest and has a constant angular acceleration of 0.110 radians.

What is angular acceleration?

The angular acceleration is the rate at which the angular velocity of an object is changing.

Therefore, since the angular acceleration of the bar is constant, this means that the angular velocity of the bar is increasing at a constant rate.

To find the angular velocity at any given time, we can use the equation: angular velocity = angular acceleration x time.

To find the final angular velocity, we can use the equation: final angular velocity = initial angular velocity + angular acceleration x time.

Therefore, the final angular velocity of the bar after 6 complete rotations is: 0 + 0.110 radians/s x (6 x 2π) = 6.832 radians/s.

To find the angle that the bar has rotated through, we can use the equation: angle = angular velocity x time

Therefore, the angle that the bar has rotated through after 6 complete rotations is: 6.832 radians/s x (6 x 2π) = 42.5 radians.

It's worth noting that angular velocity is a vector quantity, it's magnitude is given in radians/s and its direction is given by the right hand rule.

The right block must have a mass of 7.9 kg to balance the forces and remain stationary.

The two blocks remain stationary when the net force on the system is zero. In this case, the force of gravity on the two blocks is balanced by the tension in the rope connecting them. The tension in the rope can be determined using the sine of the angles and the masses of the blocks.

Tension = (mass1 × gravity) × sin(angle1) + (mass2 × gravity) × sin(angle2)

Substituting the known values:

Tension = (10 kg × 9.8 m/s²) × sin(23°) + (mass2 × 9.8 m/s²) × sin(40°)
