You are designing a spaceship, and you want it to have an artificial gravity of 9.8 m/s2 at the center of mass of an average human. The average human has a center of gravity that is about 90 cm above their feet. Through other engineering constraints, you have determined the rotational speed of the ship to be 0.2 rad/s. What should the radius of the ship be (in m)? (Round your answer to the nearest whole number!)

Answer:

Given: mass = 150 Kg

Acceleration due to gravity = 10m/s²

Force = x N

Force = Mass × Acceleration due to gravity

Force = 150 kg × 10 m/s²

Force = 1500 kgm/s² = 1500 N

The formula for calculating weight is F = m × 9.8 m/s2, where F is the object's weight in Newtons (N) and m is the object's mass in kilograms. The Newton is the SI unit for weight, and 1 Newton equals 0.225 pounds.

\(F = m × 9.8m/s² \\ F = 150 \times 9.8/ {s }^{2} \\ F = 1470 N\)

The force of gravity between two magnets is really considerably smaller than the magnetic force, despite the fact that two magnets correctly aligned would attract and stay together firmly.

Any two mass-containing things in the cosmos are subject to the basic natural force of gravity. According to the formula F = G * m1 * m2 / r2, where F is the force, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them, the gravitational force between two objects varies in strength depending on their masses and the distance between them. The magnetic fields of two magnets are what create the force between them. Two magnets are aligned properly and it causes them to stick together tightly.

The amount of kinetic energy lost is 26 kg m²/s²

The question concerns the amount of kinetic energy lost when a 3-kg toy car travelling at 6 m/s collides head-on with a 2-kg vehicle travelling in the opposite direction at 4 m/s, and the two vehicles then lock together at a speed of 2 m/s. The kinetic energy prior to and following the impact may be calculated. The post-collision kinetic energy can then be subtracted from the prior kinetic energy.

The kinetic energy before the collision is calculated by multiplying the mass of each car by its respective speed, then adding those values together:

KE(before) = (3 kg)(6 m/s) + (2 kg)(4 m/s) = 36 kg m²/s².

The kinetic energy after the collision is calculated by multiplying the combined mass of the cars by their speed after the collision:

KE(after) = (5 kg)(2 m/s) = 10 kg m²/s².

Therefore, the amount of kinetic energy lost is 36 - 10 = 26 kg m²/s².

The scattering angle at which the wavelength of the scattered X-ray is greater by 1.0% than that of the incident X-ray is approximately 0.03 degrees.

The change in wavelength of the scattered X-ray can be calculated using the formula:

Δλ = (h/mc) * (1 - cosθ)

where:

Δλ = change in wavelength

h = Planck's constant (6.626 x 10^-34 J s)

m = mass of the electron (9.109 x 10^-31 kg)

c = speed of light (3.0 x 10^8 m/s)

θ = scattering angle

To find the scattering angle at which the wavelength of the scattered X-ray is greater by 1.0% than that of the incident X-ray, we can set up the following equation:

λ_scattered = 1.01 λ_incident

where λ is the wavelength of the X-ray.

Solving for Δλ and substituting in the values for h, m, c, and the incident wavelength λ_incident, we get:

Δλ = λ_scattered - λ_incident = 0.01 λ_incident

Δλ = (h/mc) * (1 - cosθ) = 0.01 λ_incident

Rearranging and solving for cosθ, we get:

cosθ = 1 - (0.01 λ_incident mc) / h

Substituting in the values for λ_incident and solving for cosθ, we get:

cosθ = 1 - (0.01)(0.1 nm)(9.109 x 10^-31 kg)(3.0 x 10^8 m/s) / (6.626 x 10^-34 J s)

cosθ ≈ 0.999999814

Taking the inverse cosine of this value, we get:

θ ≈ 0.03 degrees

Answer:

All soft drinks contain water. When soft drink bottles are chilled in sub-zero temperatures, the water on account of its anomalous expansion expands. Thus, to provide space for expanding water, soft drink bottles are not completely filled as otherwise they will burst.

Explanation:

Answer:

Soft drink bottles are filled leaving some space between the lid/cap and the liquid level.

Explanation:

The reason is that the soft drinks are cooled below room temperature.  Sometimes they are kept in the hot Sun and weather.  They are subject to a big temperature variation.  Also, there are gases like CO2 mixed in the drink.  So the gases come out of the liquid and expand due to heat.  That creates high pressure.

Water expands when it is cooled to 4 deg. C.  But the bottle (glass) contracts when it is cooled.  So if there is no air gap,  then volume of water (cool drink) will become more than the inside volume of the bottle.  Then the bottle will break due to pressure from water expansion around 8 deg. to 4 deg.C.

When a bottle is opened, due to pressure difference, and temperature difference, the gases come out of drink in the form of bubbles.  So cold drink overflows out.

Also, the soft drink bottles are capped tightly.  When an opener is used to open it using some force upwards, the pulling force also moves the soft drink bottle upwards.  So just after the lid comes off, the top part of the drink comes out due to the pull.  So some drink spills on people who open or, it falls outside.

In order to prevent these problems, some gap is left open between the surface of the soft drink and the top of the bottle.

Answer:

W =  4 N (to balance the beam)

Explanation:

take moment at support Δ

∑M at Δ = 0 (note: clockwise is + and counter clockwise is - )

0 = W(100 - 30) + 2(60-30) + 1(50-30) - 12(30)

0 = W70 + 2(30) + 1(20) - 360

0 = W70 + 60 + 20 - 360

0 = W70 - 280

280 = W70

W = 280 / 70

W = 4 N (to balance the beam)

to take the reaction at support Δ

Δ = 12 + 1 + 2 + 4

Δ = 19 N

proof that W = 4

∑M at 12N = 0

0 = 19(30) - 1(50) - 2(60) - W(100)

0 = 570 - 50 - 120 - 100W

100W = 400

W = 400 / 100

W = 4 N -------- ok

To determine how much heat per second is produced just by the act of jogging, we'll need to consider the following terms: metabolic rate, energy expenditure, and heat production.

1. Metabolic rate: This is the amount of energy expended by the body per unit of time to maintain its basic functions. It varies depending on factors like age, weight, and activity level.

2. Energy expenditure: The total energy spent by the body during a specific activity like jogging. This includes the energy needed for muscle contraction, respiration, and other bodily functions.

3. Heat production: The amount of heat generated by the body during a physical activity, which is related to energy expenditure. The more energy spent, the more heat produced.

Now, let's calculate the heat per second produced during jogging:

Step 1: Determine the energy expenditure during jogging. This can be estimated using metabolic equivalent (MET) values. Jogging has a MET value of around 7. You can find the energy expenditure by multiplying the MET value by your body weight (in kg) and 3.5, and then dividing by 200. For example, for a 70 kg person:

Energy expenditure = (7 MET * 70 kg * 3.5) / 200 = 8.645 kcal/min

Step 2: Convert the energy expenditure per minute to per second:

Energy expenditure per second = 8.645 kcal/min / 60 seconds = 0.1441 kcal/s

Step 3: Convert the energy expenditure in kcal/s to joules/s (since 1 kcal = 4184 J):

Heat production per second = 0.1441 kcal/s * 4184 J/kcal = 602.84 J/s

So, during jogging, approximately 602.84 joules of heat are produced per second for a 70 kg person. Keep in mind that this value will vary depending on the individual's weight and other factors.

The law of conservation of matter and the law of conservation of energy essentially state that neither type of energy can be created nor destroyed, only transformed. The process by which grapes ferment to produce wine is an illustration of the law of conservation of matter. The amount of matter in the reactants in the bottle doesn't change, but its chemical form does.

It is a fundamental tenet of classical physics that matter cannot be created or destroyed in an isolated system; rather, it can only be changed from one form to another. This means that despite the apparent changes that are seen, no matter is lost during any chemical or physical change that may occur with any substance.

By using partial fraction decomposition, you can effectively massage the s-space solutions to known forms found in the tables and obtain the time-domain solution.

The primary method of massaging the s-space solutions when utilizing inverse Laplace transforms is called "Partial Fraction Decomposition."

Partial fraction decomposition involves breaking down a complex fraction in the Laplace transform domain (s-space) into simpler fractions with known inverse Laplace transforms. This allows you to look up these simpler fractions in the Laplace transform tables provided in your book, making it easier to find the time-domain solution. The steps for partial fraction decomposition are as follows:

1. Write the given Laplace transform as a proper fraction (i.e., the degree of the numerator is less than the degree of the denominator).
2. Factor the denominator of the fraction into its irreducible factors (i.e., linear or quadratic factors).
3. Write the given Laplace transform as a sum of simpler fractions with the irreducible factors as their denominators.
4. Solve for the unknown coefficients in the simpler fractions by equating coefficients or by substitution and solving a system of linear equations.
5. Use the inverse Laplace transform tables to find the corresponding time-domain solutions for each simpler fraction.
6. Combine the time-domain solutions to get the final time-domain solution for the given Laplace transform.
