What is the difference between inertial mass and weight​

The resultant speed of the person on the cruise ship is 12.62 m/s.

The resultant speed of an object is the single speed which can effectively represent two or more speed of the object.

The magnitude of the resultant speed of the person on a cruise ship is calculated as follows;

Vr² = Va² + Vb²

where;

Substitute the value of the north speed and east speed to determine the resultant speed of the person on the ship.

Vr  =  √Va² + Vb²

Vr = √[(3.9 m/s)² + (12 m/s)² ]

Vr = 12.62 m/s

Thus, for a person on a cruise ship is doing laps on the promenade deck at a speed of 3.9 m/s to the north and the speed of the ship 12 m/s to the east, the resultant speed is 12.62 m/s.

The author of Leader Within You 2.0 by Maxwell underlines the value of perseverance in Chapter 10. He emphasizes the importance of perseverance in order to succeed in any endeavor. It is crucial for leaders who want to innovate or bring about change.

Because difficulties and hurdles will inevitably come, persevering through them is essential. Maxwell gives several instances of well-known leaders who persisted despite adversity. He says that failure should not deter leaders and that they should instead see it as a chance to develop from their mistakes.

Additionally, leaders should not be scared to take chances because they are necessary for success. In his emphasis towards the end of the chapter, Maxwell stresses the need of tenacity for success and the fact that persistent individuals never give up.

Answer:

Astronauts who are orbiting the Earth often experience sensations of weightlessness. These sensations experienced by orbiting astronauts are the same sensations experienced by anyone who has been temporarily suspended above the seat on an amusement park ride. Not only are the sensations the same (for astronauts and roller coaster riders), but the causes of those sensations of weightlessness are also the same. Unfortunately however, many people have difficulty understanding the causes of weightlessness.

Answer:

x_total = 20m

Explanation:

This is an exercise in kinematics, we will look for the distance it travels during the reaction time, where there is no braking, and then the distance during the deceleration.

Distance traveled during response time

           v = x₁ / t

           x₁ = v t

let's calculate

          x₁ = 10 0.75

          x₁ = 7.5 m

Now we calculate the distance during braking, the final speed is zero (v = 0)

         v² = v₀² - 2 a x₂

         x₂ = v₀² / 2 a

let's calculate

         x₂ = 10² / (2 4)

         x₂ = 12.5m

the total stopping distance is

        x_total = x₁ + x₂

        X_total = 7.5 + 12.5

        x_total = 20m

Spectroscopic studies indicate that the majority of asteroids contain large fractions of silicate rocks.

Silicate rocks are a type of rock that contains silicon and oxygen atoms, along with other elements such as aluminum, iron, and magnesium.

These rocks are similar to the rocks found on Earth and are considered to be primitive materials from the early solar system.

However, some asteroids do contain other materials in addition to silicate rocks. For example, some asteroids are classified as C-type asteroids, which are rich in carbon and organic molecules.

Other asteroids, known as M-type asteroids, contain significant amounts of metals such as iron and nickel.

The composition of asteroids can provide important clues about the formation and evolution of the solar system.

By studying the chemical and physical properties of asteroids, scientists can gain insight into the conditions that existed in the early solar system and how planets like Earth were formed.

Additionally, asteroids may contain valuable resources that could be exploited in the future, such as water and metals.

The gravitational pull accelerates the Earth more since it is less heavy and causes it to move more quickly.

The mass of the Earth is what creates gravity. The combined gravitational force of all of its mass acts on the mass in your body. We couldn't survive without gravity. It produces the force that keeps the Earth in orbit around the Sun and keeps us on the surface of the planet. When two objects contact, forces are the mechanism by which energy is transmitted from one to the other, but forces do not themselves contain energy. Since gravity is a force, it only offers one method for objects to exchange energy and change its state.

The weakest force that humans are aware of is gravity.

Weight and gravity are not the same.

Gravity generates waves that move at light speed.

Answer:

When water freezes to form ice, the molecules would be vibrating in place rather than moving round. It is a result of a decrease in the kinetic energy of the molecules of water. It is said that the temperature and the kinetic energy of the molecules is directly proportional which means that when temperature is increased, the kinetic energy of the molecules would increase as well making the molecules move around. However for this case, when we day the system is cooled then it means the temperature is decreased which would result to the decrease of the kinetic energy of the molecules.

Explanation:

We have that when the level of mercury on either limb is the same, the pressure of the trapped air, P₁ = Atmospheric pressure

Also the initial height of the mercury in the tube = The reading of the barometer = 75.0 cm

The initial length of the air column, l₁ = 6.3 cm

The final length of the air column, l₂ = 4.2 cm (The length is expected to decrease due to compression)

The volume, V = l × A

Where;

A = The cross sectional area of the tube

Therefore, the volume of the air column is directly proportional to the length of the air column

∴ V ∝ l

According to Boyles law, we have;

P₁·V₁ = P₂·V₂

Where;

P₁ = The initial pressure in the air column before more mercury is added

V₁ = The initial volume occupied by the air in the air column

P₂, and V₂ are the final pressure and volume of the air column respectively

Given that V = l·A, we can write;

P₁·l₁·A = P₂·l₂·A

P₂ = P₁·l₁·A/(l₂·A) = P₁·l₁/(l₂) = P₁ × 6.3/4.2 = 1.5·P₁

The pressure in the air column after more mercury is added, P₂ = 1.5 × P₁

P₁ = Atmospheric pressure, therefore;

The pressure in the air column after more mercury is added, P₂ = 1.5 × Atmospheric pressure

Pressure = h·ρ·g

Where;

ρ = The density of the substance

g = The acceleration due to gravity

h = The height of the column of the fluid

Given that the density and the gravitational force, can be taken as constant, we have that the pressure of the fluid is directly proportional to the height of the fluid column

Therefore, when the pressure doubles, the height of the fluid column doubles, and when the factor of increase is 1.5, we have;

The final level of the mercury, h₂ = 1.5·h₁ = 1.5×75 cm = 112.5 cm

The initial length of the closed end of the J tube, \(h_{closed1}\) = 6.3 cm + 75 cm = 81.3 cm

The final length of the mercury in the closed end, \(h_{closed2}\) = 81.3 cm - 4.2 cm = 77.1 cm

The difference in the level of mercury, Δh = h₂ - \(h_{closed2}\)

∴ Δh = 112.5 cm - 77.1 cm = 35.4 cm

The difference in the levels of mercury in the limbs, Δh = 35.4 cm

The potential energy when the two point charges are four times as far apart would be one-sixteenth (1/16) of the original potential energy, given that potential energy is inversely proportional to the distance between the charges.

When two point charges are placed a certain distance d apart, there is a specific amount of electrical potential energy, u. This potential energy comes from the electrostatic attraction between the two charges.

As the two charges are placed further apart, the amount of potential energy between them decreases. Therefore, when the two charges are four times the original distance d apart, their potential energy is also reduced by a factor of four.

This is due to the fact that as the distance is increased, the strength of the electrostatic attraction between the two charges also decreases, thus reducing the amount of potential energy. The decrease in potential energy is proportional to the square of the increase in distance.

Therefore, when two charges are four times as far apart, the electric potential energy between them is decreased to 1/16 of the initial value.

In conclusion, The electrical potential energy between two point charges is inversely proportional to the distance between them. If the potential energy is u when the charges are a distance d apart, then when they are fourfold as far apart (4d), the potential energy will be one-sixteenth (1/4^2) of the original value (u/16).

the volume of the cavity inside the ball is 5.3 × 10⁻⁴ m³.

The density of water is 1 g/cc or 1000 kg/m³. The density of steel is 7.99 g/cc or 7990 kg/m³. Therefore, the weight of a 1.10 kg steel ball in water can be expressed as follows;

Weight of steel ball in water = Weight of steel ball - Buoyant force

\(W = mg - Fb\)

From the question, weight in water is 8.75 N, and the mass of the steel ball is 1.10 kg. Therefore,  W = 8.75 N and m = 1.10 kg.

Substituting the values in the equation above, we have;

8.75 N = (1.10 kg) (9.8 m/s²) - Fb

Solving for Fb, we have

Fb = 1.10 (9.8) - 8.75

= 0.53 N

The buoyant force is equal to the weight of the water displaced.

Thus, volume = (Buoyant force) / (density of water)

Substituting the values in the equation above, we have;

V = Fb / ρV

= 0.53 N / (1000 kg/m³)

V = 0.00053 m³

= 5.3 × 10⁻⁴ m³

Hence, the volume of the cavity inside the ball is 5.3 × 10⁻⁴ m³.

The mass of the other star in the binary system is approximately 0.541 solar masses.

To find the mass of the other star in the binary system, we can use Kepler's Third Law of Planetary Motion, which can be applied to binary star systems. The law states that the square of the orbital period (\(T\)) is proportional to the cube of the semi-major axis (\(a\)) of the orbit. Mathematically, this can be expressed as\(\(T^2 = \frac{4\pi^2}{G(M_1 + M_2)}a^3\), where \(M_1\) and \(M_2\)\)  are the masses of the stars,\(\(G\)\) is the gravitational constant, and other variables have their usual meanings.

Given that one star has a mass of 1.00 solar masses, we can substitute the known values into the equation and solve for\(\(M_2\)\). Rearranging the equation, we have\(\(M_2 = \frac{4\pi^2}{G}(\frac{a^3}{T^2}) - M_1\)\).

Plugging in the values for\(\(a\) (1.34E+10 km) and \(T\) (400 years)\), and using the appropriate unit conversions, we can calculate the mass of the other star,\(\(M_2\\), to be approximately 0.541 solar masses.

Therefore, the mass of the other star in the binary system is approximately 0.541 solar masses.
