during the first seconds of the ride, when will a person’s seat on the ferris wheel be feet above ground?

Explanation:

This happens because the gas inside tend to expand because its temperature gets higher.

This is why the balloon that is put in a freezer for too long tend to gets smaller, because the gas temperature that is inside the balloon decreases.

(you can try it at home)

It is related to the temperature of the gas.

The correct answer is e. None of the above alternatives gives a true statement. None of the statements in options a, b, c, and d are true when it comes to a modulus M over a ring R having a finite basis.

When a modulus M can be formed entirely from a finite set of elements, the modulus M is said to be finitely generated. M's finite basis does not, however, automatically imply that M is finitely generated. A basis is a set of linearly independent elements, and it might not be enough to produce all of the components of the modulus.

According to the assertion in option b, M must include nonzero items of nonzero order if it has a finite basis. This is untrue, though. The smallest positive number k, such that the element raised to the power of k equals the identity element, is referred to as the order of an element.

According to option c, every non-null element in a modulus with a finite basis has a null. Nevertheless, this claim is likewise untrue. It is possible for a modulus with a finite basis to have non-null elements without a null element.

According to option d, a ring R is a body, or a field, and only then can a modulus have a finite basis. However, this assertion is also untrue. Even though the ring R is not a field, a modulus can nonetheless have a finite basis. None of the given alternatives provides a true statement about a modulus M over a ring R having a finite basis.

Vector V perpendicular to the plane through the given points A=(-3,4,−4) , B=(-5,0,−4) , and C=(-5,0,−3) is given by V=⟨−8,−4,0⟩.

The given points A(−3,4,−4) , B(−5,0,−4) , and C(−5,0,−3) are the three points in a plane.

Let's name the plane as 'P'.

To find the vector V that is perpendicular to the plane P, we need to find the cross product of the vectors in the plane P.

Let the vector BA = A - B,

BC = C - B be the vectors in the plane P. Then, the vector V perpendicular to the plane P is given by the cross product of BA and BC.

Vector BA = A - B

= (-3 - (-5), 4 - 0, -4 - (-4))

= (2,4,0)

Vector BC = C - B= (-5 - (-5), 0 - 0, -3 - (-4))

= (0,0,1)

Therefore, the vector V that is perpendicular to the plane through the given points A, B, and C is obtained by taking the cross product of BA and BC as follows:

V = BA × BC

= |i j k| (2,4,0) (0,0,1)| 4 0 -8 |

Answer:

Ammonia is a weak base with a standard pH level of about 11.

Explanation:

Answer:

384,000

Explanation:

Time taken by light to travel from earth to moon t=1.28s

Let us assume that the speed of light = c

So, the distance traveled by light in this time = c x t

this will be the distance which light traveled to reach moon, so this will be the distance between earth and moon.

The speed of light is 300000 km/s

By putting the values

we get

Distance = c x t

= 300000 x 1.28 km

=384000 km

The rotating axis is 0.5 metres away from the rod's centre.

To calculate the rotational inertia of the meter stick about an axis perpendicular to the stick and located at the 29 cm mark, we can use the formula for the rotational inertia of a thin rod:

I = (1/3) * M * \(L^2\),

where I is the rotational inertia, M is the mass of the rod, and L is the length of the rod.

Given that the mass of the meter stick is 0.78 kg and its length is 1 meter (100 cm), we can substitute these values into the formula:

I = (1/3) * 0.78 kg * \((100 cm)^2.\)

Simplifying the equation gives:

I = 2600kg.\(cm^2\).

Converting the units to kg·\(m^2\), we divide by 10,000:

I = 0.26 kg·\(m^2\).

So, the rotational inertia of the meter stick about the axis located at the 29 cm mark is 0.26 kg·\(m^2\).

To determine the rotational inertia for a thin rod about its center, we can use the formula:

I_center = (1/12) * M *\(L^2,\)

where I_center is the rotational inertia about the center. Using the same mass (0.78 kg) and length (1 meter), we substitute these values into the formula:

I_center = (1/12) * 0.78 kg * \((100 cm)^2.\)

Simplifying the equation gives:

I_center = 650 kg·\(cm^2.\)

Converting the units to kg·\(m^2,\)we divide by 10,000:

I_center = 0.065 kg·\(m^2.\)

According to the parallel-axis theorem, the rotational inertia about an axis parallel to and displaced a distance 'd' from the center is given by:

I_displaced = I_center + M *\(d^2.\)

We know that I_displaced is equal to 0.26 kg·\(m^2\)(from the previous calculation). Substituting the values into the equation:

0.26 kg·\(m^2\)= 0.065 kg·\(m^2\)+ 0.78 kg * \(d^2.\)

Rearranging the equation, we get:

0.195 kg·\(m^2\) = 0.78 kg * \(d^2.\)

Solving for 'd', we have:

d^2 = 0.195 kg·\(m^2\) / 0.78 kg.

d^2 = 0.25\(m^2.\)

Taking the square root of both sides:

d = 0.5 m.

Therefore, the rotation axis is shifted 0.5 meters from the center of the rod.

Answer:

The volume of the ideal gas on another planet will be 6.7 m³.

Explanation:

We can find the volume occupied by the ideal gas on another planet by using the Ideal Gas Law:

\( PV = nRT \)

Where:

P: is the pressure

V: is the volume

n: is the number of moles

R: is the gas constant = 8.206x10⁻⁵ m³ atm K⁻¹mol⁻¹

T: is the temperature              

Since the gas occupies a volume of 8.7 m³ with a pressure of 6 atm and temperature 4.8 °C on earth, we have the following number of moles:

\( n = \frac{PV}{RT} = \frac{6 atm*8.7 m^{3}}{8.206 \cdot 10^{-5} m^{3}atm/(Kmol)*(4.8 + 273)K} = 2289.9 moles \)

Now we can calculate the volume occupied by the ideal gas on another planet:

\( V = \frac{nRT}{P} \)

With T = 8.7 °C and P = 7.9 atm

\( V = \frac{2289.9 moles*8.206 \cdot 10^{-5} m^{3}atm/(Kmol)*(8.7 + 273)K}{7.9 atm} = 6.7 m^{3} \)

Therefore, the volume of the ideal gas on another planet will be 6.7 m³.

The time necessary for the largest ball to reach a velocity 95% of the terminal velocity is 22.35 seconds, and for the smallest ball, it is 0.23 seconds.

Given data:

Diameter of the largest ball, d₁ = 9.52 mm

Diameter of the smallest ball, d₂ = 2.38 mm

Viscosity of glycerin, η = 1.0 Pa. s

The terminal velocity is given as:

vT = 2r²(ρs - ρ)f / 9η

where,

r is the radius of the ball,

ρ is the density of the ball,

ρs is the density of glycerin and

f is the acceleration due to gravity.

Substituting the values, we have

vT₁ = (9.52 / 2)²(ρ₁ - ρ)f / 9ηvT₂

= (2.38 / 2)²(ρ₂ - ρ)f / 9η

where, vT₁ is the terminal velocity of the largest ball and

vT₂ is the terminal velocity of the smallest ball.

The time necessary for each ball to reach a velocity 95% of the terminal velocity is given as:

t = (-m/η) ln(1 - 0.95(v/vT))

where, m is the mass of the ball,

v is the velocity of the ball and

vT is the terminal velocity of the ball.

Substituting the values, we have for the largest ball:

v = 0.95vT₁t = (-m/η) ln(1 - 0.95(0.95vT₁)/vT₁)

= 22.35s (approx)

for the smallest ball:

v = 0.95vT₂t = (-m/η) ln(1 - 0.95(0.95vT₂)/vT₂)

= 0.23s (approx)

the light falls twice the distance between the mirrors in one second. When light bounces back and forth between two vertical parallel mirrors, it creates a light path that is in the shape of a straight line. If the distance between two parallel vertical mirrors is 5 cm,

the light will take a total distance of 10 cm (2 * 5 cm) in one second. Therefore, the light will fall twice the distance between the mirrors in one second. The concept of bouncing light back and forth between mirrors is referred to as the "light path." The light will travel back and forth between two parallel mirrors, following a straight line path.

The light path will be perpendicular to the surface of the mirrors.To determine how far the light travels in one second, we must first determine the distance between the two mirrors. The light bounces back and forth between two mirrors, so it travels the distance between the two mirrors twice. We must, therefore, multiply the distance between the two mirrors by two to determine the total distance traveled by the light.In the example given, if the distance between the two mirrors is 5 cm, the total distance traveled by the light in one second will be 10 cm (2 * 5 cm).

Answer: 0.05 kgm/s

Explanation:

The volume occupied by 10 kg of water at 170°C and 800 kPa is approximately 2558 liters.

We can use the ideal gas law, v = nRT/P, to find the volume occupied by the water vapor.

We have:

P = 800 kPa

T = 170°C + 273.15 = 443.15 K (temperature in Kelvin)

n = m/M, where m is the mass of water vapor and M is the molar mass of water. The molar mass of water is approximately 18.015 g/mol.

R = 8.314 J/(mol·K) (universal gas constant)

Assuming all of the water is vaporized, we can find the number of moles of water vapor:

n = m/M = 10000 g / 18.015 g/mol = 555.45 mol

Now we can use the ideal gas law to find the volume of the water vapor:

v = nRT/P = (555.45 mol)(8.314 J/(mol·K))(443.15 K)/(800000 Pa) = 2.558 m³

To convert this to liters, we multiply by 1000:

2.558 m³ × 1000 L/m³ = 2558 L

Therefore, 10 kg of water at 170°C and 800 kPa occupies a volume of approximately 2558 liters when it is in the superheated vapor state.
