What is the new kinetic energy of the 1900 kg ship on the right moving at 4 m/s?

Answer: Galileo's laws of Motion determined that the natural state of an object is rest or uniform motion, objects always have a velocity, sometimes that velocity has a magnitude of zero rest. objects resist change in motion, which is called inertia.

Explanation:

Galileo failed to formulate equations to describe this type of motion because he was unable to prove this motion by direct or obvious means.

Galileo introduced two different propositions to describe motion of an object, which includes;

Galileo considered to define uniform acceleration as change in speed over equal change in distance or change in velocity over equal change in time of motion.

Galileo chose the later definition, "uniform acceleration as the change in velocity over equal change in time of motion".

The answers to the questions about a hot air balloon cooling down are as follows:Change of internal energy: -Heat loss: -Work done: +

The change of internal energy of the hot air balloon when it cools down is negative (-). The internal energy of the hot air balloon decreases as the balloon loses heat. Therefore, there is a decrease in internal energy, which is the sign of the heat.The heat loss of the hot air balloon when it cools down is negative (-). The hot air balloon loses heat to the cooler air surrounding it. Therefore, the heat loss is negative (-) due to the heat transfer from the hot air balloon to the cooler air.

The work done on the hot air balloon when it cools down is positive (+). When the hot air balloon cools down, it becomes denser than the surrounding air. Therefore, the weight of the hot air balloon increases, and the hot air balloon sinks down to the ground. As a result, work is done on the hot air balloon by the surrounding air to push it down to the ground.In conclusion, the sign of the heat, the change in internal energy, and the work done on the hot air balloon when it cools down are negative (-), negative (-), and positive (+), respectively.

The specific surface area, assuming equal mass of sand, silt, and clay particles with average sizes of 0.6 mm, 0.005 mm, and 0.0006 mm respectively, can be calculated to be a total of 9.53 square meters per gram.

The specific surface area refers to the total surface area of the particles per unit mass. To calculate the specific surface area, we need to determine the surface area of each type of particle and then sum them up.

First, we calculate the surface area of sand particles. The average size of sand particles is given as 0.6 mm. Assuming spherical particles, we can use the formula for the surface area of a sphere, which is 4πr^2, where r is the radius. Therefore, the surface area of a sand particle is 4π(0.3 mm)^2.

Next, we calculate the surface area of silt particles. The average size of silt particles is given as 0.005 mm. Again, assuming spherical particles, the surface area of a silt particle is 4π(0.0025 mm)^2.

Finally, we calculate the surface area of clay particles. The average size of clay particles is given as 0.0006 mm. Using the same assumption of spherical particles, the surface area of a clay particle is 4π(0.0003 mm)^2.

Now, we add up the surface areas of all three types of particles and divide by the total mass of the particles to obtain the specific surface area. This calculation yields a specific surface area of approximately 9.53 square meters per gram.

In summary, assuming equal mass of sand, silt, and clay particles with average sizes of 0.6 mm, 0.005 mm, and 0.0006 mm respectively, the specific surface area is calculated to be 9.53 square meters per gram.

A car of mass 1000 kg moving at 72 km/h is brought to rest in 10 s, the force required to stop the car is 2000 N.

For calculating the force required to stop the car, use Newton's second law of motion, which states that force is equal to mass times acceleration (F = m * a). Given that the mass of the car is 1000 kg, and need to determine the acceleration.

First, convert the initial velocity from km/h to m/s. Since 1 km/h is equal to 0.2778 m/s, the initial velocity of the car is:

72 km/h * 0.2778 m/s = 20 m/s.

Next, calculate the deceleration using the equation:

a = (final velocity - initial velocity) / time.

The final velocity is 0 m/s (since the car comes to rest), the initial velocity is 20 m/s, and the time taken to stop is 10 s.

Plugging these values into the equation:

\(a = (0 m/s - 20 m/s) / 10 s = -2 m/s^2\)

Finally, entering the values of mass (1000 kg) and acceleration (\(-2 m/s^2\)) into the formula F = m * a for finding the required force:

\(F = 1000 kg * (-2 m/s^2) = -2000 N\)

Therefore, the force required to stop the car is 2000 N.

Answer:

fhdfhiffifioo

Explanation:

Among the variables mentioned, the most important factor that influences drag on an object in the experiments conducted is the object's area.

Drag is the force that opposes the motion of an object through a fluid (such as air or water). It depends on several factors, including the object's area, shape, speed, and the properties of the fluid. However, in the context of the experiments conducted, the area of the object is the most significant factor.

The larger the surface area of an object facing the fluid flow, the greater the drag force it experiences. This is because a larger area creates more resistance to the fluid, resulting in higher drag. Other variables mentioned, such as the length, roughness, specific gravity, material, and density of the object, may indirectly influence drag by affecting the object's shape or ability to streamline, but they are not as directly correlated to drag as the area.

By controlling the area of the object in the experiments, researchers can investigate the impact of drag on the object's motion. Altering the object's area allows for comparative analysis to understand how changes in surface area affect the drag force experienced, providing insights into fluid dynamics and the relationship between objects and their environment.

We will have that the picture that shows the highest average kinetic energy is image B.

Answer:

The applied force on the vehicle is 5,000 N

Explanation:

From the question, we have the following parameters of the motion of the vehicle;

The form of the velocity with which the vehicle is travelling = Uniform velocity

The direction of motion of the vehicle = Along a straight and level stretch of the highway

The combined force which acts as resistance to the vehicle's motion = 5,000 N from rolling friction and resistance of the air opposite to the direction of motion

A vehicle travelling with uniform velocity has zero acceleration, therefore;

The acceleration of the vehicle, a = 0 m/s²

According to Newton's Second Law of Motion, we have;

Force, F = Mass, m × Acceleration, a

∴ The net force of acting on the vehicle, F = m × a

Where;

m = The mass of the vehicle

a = The acceleration of the vehicle = 0 m/s²

∴ F = m × 0 = 0

The net force on the vehicle = 0, therefore;

The applied force + The force of rolling friction and air resistance = 0

We therefore have;

The applied force + 5,000 N = 0

∴ The applied force = 0 - 5,000 N = -5,000 N

The applied force, F = 5,000 N in the direction of motion.

Answer:

Approximately \(1.1 \times 10^{-32}\; {\rm m}\).

Explanation:

Look up Planck's Constant: \(h \approx 6.626 \times 10^{-34}\; {\rm kg \cdot m^{2} \cdot s^{-1}}\).

If the momentum of a moving object is \(p\), the de Broglie wavelength \(\lambda\) of that object will be \(\lambda = h / p\).

The mass of the object in this question is \(m = 3.3 \times 10^{-4}\; {\rm kg}\). At a velocity of \(v = 175\; {\rm m\cdot s^{-1}}\), the momentum \(p\) of this object will be:

\(\begin{aligned}p &= m\, v \\ &= 3.3 \times 10^{-4}\; {\rm kg} \times 175\; {\rm m\cdot s^{-1}} \\ &= 0.05775\; {\rm kg \cdot m \cdot s^{-1}}\end{aligned}\).

Substitute the value of \(p\) and \(h\) into the equation \(\lambda = h / p\) to find the de Broglie wavelength \(\lambda\) of this moving object:

\(\begin{aligned}\lambda &= \frac{h}{p} \\ &\approx \frac{6.626 \times 10^{-34}\; {\rm kg \cdot m^{2} \cdot s^{-1}}}{0.05775\; {\rm kg \cdot m \cdot s^{-1}}} \\ &\approx 1.1 \times 10^{-32}\; {\rm m}\end{aligned}\).

(Note the units. Rounded to two significant figures as in mass \(m\).)

Therefore, the de Broglie wavelength of this moving object will be approximately \(1.1 \times 10^{-32}\; {\rm m}\).

The wavelength is equal to 1.1 × 10⁻³² m when the mass of 3.3 ×10⁻⁴ Kg and a velocity of 175 m/s.

The de Broglie equation can be described as the equation that is commonly used to define the wave properties of matter.

As the smaller particle has dual nature, energy is the same. The equation gives relations for the particle moving with velocity ‘v’ as,

\(\lambda = \frac{h}{mv}\)

Where ‘h’ is the Plank’s constant, h = 6.626 × 10⁻³⁴ J.s

Given the mass of the bullet, m = 3.3 ×10⁻⁴ Kg

The velocity, v = 175 m/s

The wavelength can be determined from the De-Broglie equation:

\(\lambda =\frac{6.626\times 10^{-34}kgm^2s^{-1}}{3.3\times 10^{-4}Kg\times 175m.s^{-1}}\)

λ = 1.1 × 10⁻³² m

Si metemos el vaso en la heladera durante un par de horas, (sabemos que la manteca en la heladera se mantiene sólida) veremos que la manteca se solidificó en la parte de arriba, mientras que el agua sigue líquida.

Entonces encontramos dos compuestos con distintas temperaturas para cambio de fase, pero materiales es más específico, y puede referirse a materiales puros.

Entonces vamos a dos metales:

Primero tenemos una pieza de hierro y una de mercurio en el congelador (supongamos que ambas están a 0°C).

Ahora los sacamos del congelador y los dejamos llegar a temperatura ambiente.

Como bien sabemos, el mercurio es líquido a temperatura ambiente, entonces el mercurio va a sufrir un cambio de fase

Ahora pensemos en el hierro; claramente va a seguir siendo sólido a temperatura ambiente, entonces podemos ver dos materiales cuyo cambio de fase de sólido a líquido ocurre en distintas temperaturas, por lo que podemos concluir que no, la temperatura de cambio de estado no puede ser igual para todos los materiales, y esto se debe a que la estructura atómica de todos los materiales es diferente.

The corresponding distance traveled by the orbiter is 1,728.05 feet. Given that the deceleration in feet per second squared during the time that the chute is deployed is −0.0003v2 (speed v in feet per second), the corresponding distance traveled by the orbiter can be found using the equation below;

The equation is:ds=∫v₁ᵛ₂dt Let's put in the values we have;v₁ = 200 mi/hr = 200 * 1.467 = 293.4 ft/s, v₂ = 35 mi/hr = 35 * 1.467 = 51.345 ft/s

∫ds= ∫v₁ᵛ₂ dt = ∫v₁ᵛ₂ (-dv/0.0003v²) = [-1/0.0003 ∫(1/v²)dv] from v₁ to v₂= [-1/0.0003 (-1/v)] from v₁ to v₂ = [1/0.0003 (1/v₁ - 1/v₂)]

The distance covered by the shuttle during the time that the chute is deployed is given by 1/0.0003 (1/v₁ - 1/v₂).∴ d = 1/0.0003 (1/293.4 - 1/51.345) = 1,728.05 feet. Therefore, the corresponding distance traveled by the orbiter is 1,728.05 feet.

The five longest wavelength of the Lyman series is R/4, 8R/9, 15R/16, 24R/25, 35R/36.

(a) According to the Rydberg formula,

1/λ = R (1/n1^2 - 1/n2^2)

where

R is the Rydberg constant,

n1 and n2 are positive integers with n2 > n1, and

λ is the wavelength of the light emitted

For the Lyman series, n1 = 1 and n2 = n.

Therefore,1/λ = R (1/1^2 - 1/n^2)

The longest wavelengths will be obtained when n is as large as possible.

Therefore, we will let n equal the first five integers greater than 1, which are 2, 3, 4, 5, and 6.

1/λ = R (1/1^2 - 1/2^2) = R/4

1/λ = R (1/1^2 - 1/3^2) = 8R/9

1/λ = R (1/1^2 - 1/4^2) = 15R/16

1/λ = R (1/1^2 - 1/5^2) = 24R/25

1/λ = R (1/1^2 - 1/6^2) = 35R/36

We can compare the wavelengths by comparing the denominators of the fractions.

The lowest denominator is 4, so the longest wavelength is associated with the first line.

We can order the other lines in the same manner.

1/λ (line 1) > 1/λ (line 2) > 1/λ (line 3) > 1/λ (line 4) > 1/λ (line 5)

The positions of these lines can be marked along a linear scale of wavelength, where the distance between each line is proportional to the reciprocal of the wavelength.

(b) The difference between the wavelengths of any two successive lines in the Lyman series can be found by taking the difference of their respective wavelengths:

1/λn - 1/λn+1 = R (1/1^2 - 1/n^2) - R (1/1^2 - 1/(n+1)^2)

This expression can be simplified by using a common denominator:

1/λn - 1/λn+1 = R (n+1)^2 / [n^2 (n+1)^2 λn λn+1]

Since λn < λn+1, it follows that λn λn+1 > λn^2.

Therefore, the denominator is greater than n^2 (n+1)^2 λn^2:

1/λn - 1/λn+1 > R / [n^2 (n+1)^2 λn^2]

This shows that the difference in wavelength between successive lines becomes smaller and smaller as n increases. Therefore, the lines get closer and closer together. As n approaches infinity, the denominator of the right-hand side of the inequality approaches infinity, so the difference between successive lines approaches zero.

This limit is called the series limit and is shown by the horizontal line in part (a) of the figure.

The balloon will go upward with acceleration of 3.1 m/s².

The upward force applied to an object that is fully or partially submerged in a fluid is known as the buoyant force. Upthrust is another name for this upward thrust. A body submerged partially or completely in a fluid appears to lose weight, or to be lighter, due to the buoyant force.

Given that

Mass of the balloon = 80 g = 0.080 kg.

Volume of the balloon = 0.3 m³.

So, weight of the balloon =  0.080 × 9.8 N = 0.784 N.

Buoyant force acting on the balloon = 0.3 × 0.35 × 9.8 N = 1.029 N.

Hence, net upward force acting on the balloon is =   1.029 N -  0.784 N =  0.248 N.
