Americium-241 is widely used in smoke detectors. Calculate the amount of americium-241 consumed in a smoke detector (initially containing 5. 00 µg of am) that has been used for one year if the half-life is 433 years.

Answers

Answer 1

0.008 μg of americium-241 was consumed in a smoke detector

The half life of a substance is:

[tex]N=N_o(\frac{1}{2} )^\frac{t}{t_\frac{1}{2} } \\\\Where\ N\ is\ the \ amount \ of\ substance\ remaining\ after\ t\ years,\\N_o\ is\ the\ original\ amount, t_\frac{1}{2} \ is\ half\ life.\\\\\\Given\ N_o=5\ \mu g,t=1\ year,t_\frac{1}{2} =433\ years. Hence:\\\\N=5*10^{-6}(\frac{1}{2} )^\frac{1}{433} =4.992\ \mu g[/tex]

The amount consumed = 5 - 4.992 = 0.008 μg

0.008 μg of americium-241 was consumed in a smoke detector.

What mass of glucose (C6H12O6) should be dissolved in 12. 0 kg of water to obtain a solution with a freezing point of -5. 8 ∘C?.

Answers

Answer:

6.740 kg

Explanation:

6.740 kg is the mass of glucose (C6H12O6) should be dissolved in 12. 0 kg of water to obtain a solution with a freezing point of -5. 8 ∘C.

What is freezing point?

The temperature at which a liquid freezes is known as the freezing point. The freezing point normally rises with increased pressure, much like the melting point does. Combinations and some organic materials, such lipids, have freezing points that are lower than melting points.

The freezing point of a material is the temperature at which a liquid turns into a solid. The liquids' freezing temperatures can be super-cooled much below, postponing the point at which they solidify. The freezing point of water is 0 °C, or 32 °F.

The most common and commonplace example of freezing is the creation of ice cubes in an ice tray when water is placed in the freezer for a period.

Thus, it is 6.740 kg.

Answers

Answer:

aaaaaaaaaaaaaaaaaaaaaaaaaa it a

Explanation:

Albert Einstein’s Theory of Relativity is the scientific innovation occurred that affected the art that was produced during this period. The correct option is A.

What is Albert Einstein’s Theory of Relativity?

Albert Einstein's Theory of Relativity is a set of two interrelated theories that fundamentally changed our understanding of space, time, and gravity. The first theory, called Special Relativity, was published by Einstein in 1905 and dealt with the physics of objects moving at high speeds. The second theory, called General Relativity, was published in 1915 and extended the ideas of Special Relativity to include gravity.

Special Relativity postulates that the laws of physics are the same for all observers who are moving at a constant speed relative to one another. This means that there is no single "absolute" time or space, but rather that these concepts are relative to the observer's frame of reference. The theory also introduced the concept of time dilation, which means that time appears to slow down for objects moving at high speeds relative to a stationary observer.

General Relativity, on the other hand, describes gravity as the curvature of spacetime caused by the presence of matter and energy. In this theory, massive objects warp the fabric of spacetime, causing other objects to move along curved paths. This explains why objects orbit around each other, as well as the bending of light around massive objects.

Einstein's Theory of Relativity has had a profound impact on modern physics and our understanding of the universe. It has led to the development of new technologies such as GPS and has provided a framework for further research into the nature of the universe, including the study of black holes, the Big Bang, and the search for a unified theory of physics.

Here in the Question,

This scientific innovation, introduced in the early 20th century, revolutionized the way scientists and artists understood space, time, and the nature of reality. The concept of relativity, which challenged the traditional Newtonian worldview, had a significant impact on modern art movements such as Cubism and Futurism, which sought to depict multiple perspectives and the dynamic nature of reality. The theory also had a profound influence on the development of abstract art, which aimed to represent the invisible forces and structures that underlie the visible world.

Therefore, The best answer is A. Albert Einstein’s Theory of Relativity.

How did the animals' attitude towards their food change, reflecting their newfound sense of accomplishment and ownership?

The animals' happiness and acute positive pleasure in consuming the food highlights their pride and satisfaction in growing and supplying their own sustenance, a departure from the times when they were dependent on their masters for meager rations.

This transformation underscores their sense of achievement and autonomy.

Answers

Answer:

1

Explanation:

The expression that is equivalent to [(2a⁻³b⁴)²/(3a⁵b)⁻²]⁻¹ is;

1/(36a⁴b¹⁰)

The given expression is;

[(2a⁻³b⁴)²/(3a⁵b)⁻²]⁻¹

Rewriting this equation gives;

[(2a⁻³b⁴)² × (3a⁵b)²]⁻¹

Let us simplify (2a⁻³b⁴)² to get;

4b⁸/a⁶

Similarly for (3a⁵b)²;

⇒ 9a¹⁰b²

Thus, we now have;

[(4b⁸/a⁶) × 9a¹⁰b²]⁻¹

From laws of indices, we know that; x⁵/x³ = x⁽⁵ ⁻ ³⁾ = x²

Thus; a¹⁰/a⁶ = a⁴

Similarly  b⁸ × b² = b⁽⁸ ⁺ ²⁾ = b¹⁰

Thus, we now have;

[(4b⁸/a⁶) × 9a¹⁰b²]⁻¹ = (36a⁴b¹⁰)⁻¹

Finally, we now have;

(36a⁴b¹⁰)⁻¹ = 1/(36a⁴b¹⁰)

What is the total kinetic energy of a 0. 15 kg hockey puck sliding at 0. 5 m/s and rotating about its center at 8. 4 rad/s? the diameter of the hockey puck is 0. 076 m.

Answers

The mass of the puck is

m = 0.15 kg.

The diameter of the puck is 0.076 m, therefore its radius  is

r = 0.076/2 = 0.038 m

The sliding speed is

v = 0.5 m/s

The angular velocity is

ω = 8.4 rad/s

The rotational moment of inertia of the puck is

I = (mr²)/2

 = 0.5*(0.15 kg)*(0.038 m)²

 = 1.083 x 10⁻⁴ kg-m²

The kinetic energy of the puck is the sum of the translational and rotational kinetic energy.

The translational KE is

KE₁ = (1/2)*m*v²

      = 0.5*(0.15 kg)*(0.5 m/s)²

      = 0.0187 j

The rotational KE is

KE₂ = (1/2)*I*ω²

      = 0.5*(1.083 x 10⁻⁴ kg-m²)*(8.4 rad/s)²

      = 0.0038 J

The total KE is

KE = 0.0187 + 0.0038 = 0.0226 J

Answer: 0.0226 J

What is the measure of arc BEC in circle D? 134° 150 209° 210°.

Answers

Answer:

134°

Explanation:

The measure of arc BEC in circle D is 134°. The correct option is 1.

What is circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called "centre".

The line of reflection symmetry is formed by every line that passes through the circle.

We've been given a circle image and asked to calculate the measure of arc BEC.

That angle is visible to us. ABC is an inscribed angle, and its measure is one-half the length of its subtended arc.

Here,

AC = 2 x m∠ABC

AC = 2 x 75°

AC = 150°

We can set an equation to find the measure of arc BEC because we know that the circumference of a 360 degree is:

Arc BEC + Arc AB + Arc AC = 360°

Arc BEC + 76° + 150° = 360°

Arc BEC + 226° = 360°

Arc BEC = 134°

Thus, the answer is 1.

Evaluate the line integral, where c is the given curve. (x + 8y) dx + x2 dy, c c consists of line segments from (0, 0) to (8, 1) and from (8, 1) to (9, 0).

Answers

Parameterize the path from (0, 0) to (8, 1) by

• x(t) = 8t and y(t) = t

and the path from (8, 1) to (9, 0) by

• x(t) = 8 + t and y(t) = 1 - t

both with 0 ≤ t ≤ 1.

Over the first path, we have

[tex]\displaystyle \int_{C_1} (x+8y) \, dx + x^2 \, dy = \int_0^1 (8t + 8\cdot t) \cdot (8 \, dt) + (8t)^2 \cdot dt = \int_0^1 (128t + 64t^2) \, dt = \frac{256}3[/tex]

and over the second path,

[tex]\displaystyle \int_{C_2} (x+8y) \, dx + x^2 \, dy = \int_0^1 ((8 + t) + 8(1-t)) \cdot dt + (8+t)^2 \cdot (-dt) \\\\ = \int_0^1 (-48 - 23t - t^2) \, dt = -\frac{359}6[/tex]

and so the total line integral is
