Answer:

\(d=1.8\ g/cm^3\)

Explanation:

Given that,

Mass, m = 27 grams

Volume of the substance, V = 15 cm³

We need to find the density of the substance. We know that, the density of an object is given by mass per unit volume. So,

\(d=\dfrac{m}{V}\\\\d=\dfrac{27}{15}\\\\d=1.8\ g/cm^3\)

So, the density of the substance is equal to \(1.8\ g/cm^3\).

a) frequency is 2.35 Hz (b) amplitude is 18.3 cm (c) period of the motion is 0.4255 s.

We're given the position equation for an oscillating object on a spring: x = (18.3 cm) cos[(2.35 s^-1)t]. We need to find the (a) frequency, (b) amplitude, and (c) period of this motion.

a) Frequency: The frequency is the coefficient of the time 't' inside the cosine function. In our equation, the frequency is 2.35 s^-1 or 2.35 Hz.

b) Amplitude: The amplitude is the maximum displacement from the equilibrium position, which is the coefficient of the cosine function. In our equation, the amplitude is 18.3 cm.

c) Period: The period is the time it takes for the motion to complete one full cycle. It is the reciprocal of the frequency. We can calculate the period as follows: T = 1/frequency = 1/(2.35 s^-1) = 0.4255 s (rounded to 4 decimal places).

So, the frequency is 2.35 Hz, the amplitude is 18.3 cm, and the period is 0.4255 s for this oscillating motion.

Low-pressure systems rotate in a counter-clockwise direction due to the Coriolis effect. The Coriolis effect is caused by the rotation of the Earth and the resulting deflection of moving objects in relation to the Earth's surface.

In the Northern Hemisphere, low-pressure systems are characterized by converging winds that spiral inward towards the center. As air flows from high-pressure areas to low-pressure areas, it experiences the Coriolis effect. The Coriolis force deflects the air to the right in the Northern Hemisphere, causing the air to rotate counterclockwise around the low-pressure center.

Conversely, in the Southern Hemisphere, the Coriolis effect causes air to deflect to the left. As a result, low-pressure systems in the Southern Hemisphere rotate in a clockwise direction.

The rotation direction of low-pressure systems is a direct consequence of the Coriolis effect and is consistent with the general atmospheric circulation patterns on Earth.

Increase magnification of a refracting telescope without reducing light-gathering power: shorter focal length eyepiece, longer telescope focal length, and larger aperture ensure higher magnification and clear, bright images.

You can do the following things to raise a refracting telescope's magnification without lowering its capacity for light-gathering:

1. Use an eyepiece with a shorter focal length: The magnification of a refracting telescope is determined by the ratio of the focal length of the telescope's objective lens to the focal length of the eyepiece. By using an eyepiece with a shorter focal length, you can achieve higher magnification.

2. Increase the telescope's focal length: Increasing the focal length of the objective lens will also increase the telescope's magnification. This can be done by either using a telescope with a longer focal length or adding a Barlow lens or a focal extender to increase the effective focal length.

3. Ensure adequate light gathering: To maintain the light-gathering power while increasing magnification, it's important to use a telescope with a sufficiently large aperture. The aperture determines the amount of light the telescope can gather. A larger aperture allows more light to enter the telescope, resulting in brighter and clearer images.

By adjusting the eyepiece, the focal length, and the telescope's aperture, you can increase the magnification of a refracting telescope without compromising its light-gathering power.

Answer:

Explanation:

Resilience in materials science refers to the ability of a material to absorb and store elastic energy when deformed and then release it upon removal of the applied force. It measures the material's capacity to resist deformation and return to its original shape after being subjected to stress.

b) The resilience of a material can be calculated using the formula:

Resilience = (1/2) * (stress^2) / (Young's Modulus)

To calculate the resilience of the polymer rod, we need to determine the stress applied to the rod. Stress is defined as force divided by the cross-sectional area of the rod.

Given:

Diameter = 65 cm

Radius (r) = Diameter / 2 = 65 cm / 2 = 32.5 cm = 0.325 m

Force (F) = 25.0 N

Young's Modulus (E) = 203.11 Pa

The cross-sectional area of the rod can be calculated using the formula for the area of a circle:

Area = π * (radius^2)

Substituting the values, we get:

Area = π * (0.325 m)^2

Now, we can calculate the stress:

Stress = Force / Area

Once we have the stress, we can calculate the resilience using the formula mentioned above.

The aforementioned circumstances can result in the production of 0.119 moles of ammonia (NH3).

We must utilize the ideal gas law and the stoichiometry of the balanced chemical equation for the reaction between hydrogen (H2) and nitrogen (N2) to make ammonia in order to determine how many moles of ammonia (NH3) were produced.

Let's begin by formulating the reaction's balanced equation:

3H₂ + N₂ → 2NH₃

We can see from the equation that we produce 2 moles of ammonia for every 3 moles of hydrogen. As a result, the molar ratio of ammonia to hydrogen is 2:3.

We must convert the supplied parameters of 4.0 liters of hydrogen at 50.0 °C and 1.2 atm of pressure into moles in order to use the ideal gas law. The ideal gas law and the molar volume of an ideal gas at standard temperature and pressure (STP) may be combined using the equation shown below:

PV = nRT

Where:

The temperature must first be converted from Celsius to Kelvin:

T(K) = T(°C) + 273.15

T(K) = 50.0°C + 273.15 = 323.15 K

To solve for the number of moles (n), we may now rearrange the ideal gas law equation as follows:

n = PV / RT

n = (1.2 atm) * (4.0 L) / (0.0821 L·atm/(mol·K) * 323.15 K) ≈ 0.179 mol

Since ammonia and hydrogen have a 2:3 molar ratio, we can calculate the amount of ammonia created by multiplying (2/3) * 0.179 mol by 0.119 mol.

As a result, the circumstances allow for the production of 0.119 moles of ammonia.

a) The initial height of the center of mass of the can and soda is 6.0 cm.

b) After the soda is drained out, the height of the center of mass of the can alone is still 6.0 cm.

c) As the soda drains out, the center of mass of the can and remaining soda will rise.

d) The height of the remaining soda when the center of mass reaches its lowest point is 4.77 cm.

a) To find the initial height of the center of mass, we can use the fact that the center of mass of a uniform object is located at the geometric center. Since the can is uniform, the center of mass is at the midpoint of its height, which is 12.0 cm / 2 = 6.0 cm.

b) When all of the soda is drained out, the mass of the can will be 0.140 kg and the height of the can will still be 12.0 cm. Since the can is now empty, the center of mass will be at the midpoint of its height, which is 12.0 cm / 2 = 6.0 cm.

c) As the soda drains out, the center of mass of the can and remaining soda will rise. This is because the soda has a lower density than the can, so the center of mass of the can and soda system is initially lower than the center of mass of the empty can alone. As the soda drains out, the average density of the remaining material increases, causing the center of mass to rise.

d) Let x be the height of the remaining soda at any given instant. The center of mass of the can and remaining soda is given by

h = (m1h1 + m2h2) / (m1 + m2)

where m1 is the mass of the can, m2 is the mass of the remaining soda, h1 is the height of the can (12.0 cm), h2 is the height of the remaining soda (x), and h is the height of the center of mass.

To find the lowest point of the center of mass, we need to find the minimum value of h. Taking the derivative of h with respect to x and setting it to zero, we get

dh/dx = m1 / (m1 + m2) - m2h1 / (m1 + m2)^2 = 0

Solving for x, we get

x = h1 × m1 / m2

Substituting the given values, we get

x = 12.0 cm × 0.140 kg / 0.354 kg = 4.77 cm

Explanation:

The star exploded approximately: 3.3 million years ago.

We can use the radioactive decay equation to solve this problem, which is:
N = N₀ (1/2)^(t/t₁/₂)
where N is the current amount of the radioactive substance, N₀ is the initial amount, t is the time elapsed since the decay started, and t₁/₂ is the half-life of the substance.

Let's assume that the initial amount of iron-60 was 100 units, and that 71% of it has decayed. Then the current amount of iron-60 is:
N = 100 - 0.71(100) = 29
Substituting these values into the decay equation, we get:
29 = 100 (1/2)^(t/2.6×10^6)

Dividing both sides by 100 and taking the logarithm of both sides, we get:
log(0.29) = (t/2.6×10^6) log(1/2)

Solving for t, we get:
t = -2.6×10^6 × (log(0.29) / log(1/2)) ≈ 3.3 million years
