Answer:

Distance is a scalar quantity, and displacement is a vector quantity

Distance is a scalar parameter and displacement is a vector quantity. Therefore, option (D) is correct.

The distance of a body can be described as the total length traveled by an object. Distance is a scalar quantity because it has only magnitude with no direction. The distance will be always positive (+ve), it can never be zero.

The displacement of a body can be described as the shortest length between two points. The displacement is a vector quantity because it contains both direction and magnitude. The displacement of an object can be positive (+ve), negative (-ve), or zero and can change with time.

The distance can be described as how much ground an object has covered during its motion while displacement is the smallest value of the length between starting and the ending point.

Therefore displacement is a vector while distance is a scalar quantity.

In ancient times, Astronomy was predicting the motion of the stars, while Astrology was predicting how those stars affected us.

 If a star is moving away, its light waves get stretched out to longer, redder, wavelengths, producing a redshift. The faster the star, the greater this shift, so observers can measure the line-of-sight speed from the Doppler shift.the astronomer William Herschel (1738-1822) systematically measured the proper motion of stars in the sky. He found that stars were moving apart in one region and coming closer together in another, and concluded that the Sun was moving toward the region where stars are moving apart.

Explanation:

The coefficient of kinetic friction between the box and the plane would be 0.577.

The forces acting on the box can be resolved into two components: the force parallel to the incline, which is 45.0 N, and the force perpendicular to the incline, which is equal to the weight of the box, mg.

The force parallel to the incline can be written as Fpar = mgsinθ, where θ is the angle of the incline, and g is the acceleration due to gravity (9.81 m/s^2).

Since the box is being pulled at a constant speed, the force of kinetic friction, F, is equal in magnitude to the parallel force, Fpar. Thus, we can write:

F = mgsinθ = 5.00 kg x 9.81 m/s^2 x sin(30o) = 24.5 N

μ = F / Fperp = (mgsinθ) / (mgcosθ) = tanθ

Substituting the value of θ, we get:

μ = tan(30o) = 0.577

Therefore, the coefficient of kinetic friction between the box and the plane is 0.577.

It takes 20 seconds for the rider to reach the low point and be 0 ft above the ground.

Since the Ferris wheel has a diameter of 50 ft, its radius is 25 ft (50/2 = 25). The rider will be 0 ft above the ground at the lowest point of the ferris wheel, which is when they are at the bottom of the wheel.

The circumference of the ferris wheel can be calculated using the formula C = 2πr, where r is the radius.
C = 2π(25) = 50π ft

The time it takes for one revolution is given as 40 seconds.

To find the time it takes for the rider to reach the low point, we need to determine what fraction of one revolution it takes to get there.
One revolution is equal to the circumference of the ferris wheel, which we calculated as 50π ft.
So, the distance the rider needs to travel to reach the low point is half of the circumference, which is 25π ft.

The time it takes to travel this distance can be calculated using the formula t = d/v, where d is the distance and v is the velocity. The velocity can be calculated by dividing the distance traveled in one revolution (50π ft) by the time it takes for one revolution (40 seconds).
v = (50π ft) / (40 seconds) = (5/4)π ft/s

t = (25π ft) / ((5/4)π ft/s) = 20 seconds

Managers' personalities can be described by a point on a scale where each of the Big Five traits has a high and low range.

The Big Five personality traits, also known as the Five-Factor Model (FFM), provide a framework for understanding and describing human personality. These traits include openness, conscientiousness, extraversion, agreeableness, and neuroticism. Each trait exists on a spectrum, ranging from high to low levels. For example, someone may exhibit high levels of openness if they are curious, imaginative, and open to new experiences, while low levels of openness may indicate a preference for routine and tradition. Similarly, the other traits—conscientiousness, extraversion, agreeableness, and neuroticism—also have their high and low ranges, capturing various aspects of an individual's personality. By assessing where individuals fall on these trait dimensions, we can gain insights into their managerial style and approach to work.

Answer:

the distance covered by the car is 95.4 m.

Explanation:

Given;

initial velocity of the car, u = 36 m/s

acceleration of the car, a = -2.8 m/s²

time of motion of the car, t = 3 s

The distance covered by the car is calculated as;

s = ut + ¹/₂at²

s = 36(3) + ¹/₂ x (-2.8)(3)²

s = 108 - 12.6

s = 95.4 m

Therefore, the distance covered by the car is 95.4 m.

Rapid gas exchange can be accomplished more easily in air than in water because air has a lower viscosity and contains a higher concentration of oxygen compared to water.

The lower viscosity of air means that it offers less resistance to the movement of gases, allowing for quicker diffusion. In contrast, water has a higher viscosity, making it more challenging for gases to move and diffuse rapidly.

Furthermore, the higher concentration of oxygen in air facilitates efficient gas exchange. Oxygen is required for respiration, and organisms need to extract oxygen from their environment to support metabolic processes. Air contains a higher percentage of oxygen compared to water, which enhances the availability of oxygen for respiration.

Additionally, the physical properties of air, such as its lower density and higher compressibility compared to water, further facilitate gas exchange. These properties enable organisms to more easily ventilate their respiratory surfaces and exchange gases with the surrounding environment.

Mass of the block, m = 3 kg

\(Spring \ constant, K = \dfrac{100 \, N}{0.1 \, m} = \mathbf{ 1000\, N/m}\)

Coefficient of kinetic friction, \(\mu_k\) = 0.39

Therefore, we have;

Friction force = \(\mathbf{\mu_k}\)·m·g·cos(θ)

Which gives;

Friction force = 0.39 × 3 × 9.81 × cos(48°) ≈ 7.68

Work done by the motion of the block, W ≈ 7.68 × d

The work done = The kinetic energy of the block, which gives;

\(\mathbf{\dfrac{1}{2} \times k \cdot x^2 }= 7.68 \cdot d\)

The initial kinetic energy in the spring is found as follows;

K.E. = 0.5 × 1000 N/m × (0.1 m)² = 5 J

The initial velocity of the block is therefore;

5 = 0.5·m·v²

v₁ = √(2 × 5 ÷ 3) ≈ 1.83

Work done by the motion of the block, W ≈ 7.68 N × 0.07 m ≈ 0.5376 J

Chane in kinetic energy, ΔK.E. = Work done

ΔK.E. = 0.5 × 3 × (v₁² - v₂²)

Which gives;

ΔK.E. = 0.5 × 3 × (1.83² - v₂²) = 0.5376

Which gives;

The height at which the block will stop moving, h, is given as follows;

\(At \ the \ maximum \ height, \ h, \ we \ have ; \ \dfrac{1}{2} \times 1000 \times 0.1^2 = 7.68 \times x\)

The pressure will 657 MM Hg.

The relationship between pressure and temperature for a fixed volume of an ideal gas can be described by the Ideal Gas Law: PV = nRT, where P is the pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in Kelvin.

P1 = (700 mm Hg) x (101.3 kPa / 1 mm Hg) = 70,910 Pa

T1 = (50 + 273.15) K = 323.15 K

T2 = (30 + 273.15) K = 303.15 K

P2 = (70,910 Pa) x (303.15 K / 323.15 K) = 65,688 Pa

Therefore, the pressure at a temperature of 30°C while keeping the volume constant would be 65,688 Pa, which is equivalent to 657 mm Hg.

Since the volume is constant in this case, we can see that the pressure is directly proportional to the temperature. Therefore, if we decrease the temperature by 20°C, the pressure will also decrease by a factor of (T2/T1)(1-γ), where γ is the adiabatic index of the gas. In reality, the pressure will not decrease exactly as calculated using the Ideal Gas Law, since the gas is not an ideal gas and the volume may not remain constant. However, the Ideal Gas Law provides a useful approximation in many situations.

The average change in momentum for the car during the trip is 8400 kg·m/s.

What is Momentum?

Momentum is a vector quantity, meaning it has both magnitude and direction. The direction of momentum is the same as the direction of velocity, and its magnitude is proportional to both the mass and the velocity of the object.

Then, we calculate the final momentum of the car during the remaining 3 hours:

Final momentum during the remaining 3 hours = mass × final velocity during the remaining 3 hours = m × v2

Now, we can calculate the average change in momentum:

Average change in momentum = Final momentum - Initial momentum

= (Final momentum during the first 2 hours + Final momentum during the remaining 3 hours) - Initial momentum

= [(m × v2) + (m × v2)] - (m × v1)

= 2m × v2 - m × v1

Plugging in the given values:

Mass of the car (m) = 1400 kg

Initial velocity (v1) = 32 m/s

Final velocity during the first 2 hours (v2) = 38 m/s

Average change in momentum = 2m × v2 - m × v1

= 2 × 1400 kg × 38 m/s - 1400 kg × 32 m/s

= 53200 kg·m/s - 44800 kg·m/s
