a solid sphere and a hollow sphere have the same mass and radius. they are rotating with the same angular speed. which one has the higher angular momentum?

Answers

Answer 1

Answer:

Answer:

I. The hollow sphere has the greater angular momentum.

Explanation:

Given that the mass and radius of hollow sphere and solid sphere are same. Let the mass and radius of two spheres be m and r respectively. The two spheres are rotating having same angular velocity ω .

Moment of inertia of solid sphere, I₁ =

Moment of inertia of hollow sphere, I₂ =

Since, I₁ and I₂ are not equal. Therefore, the statement iv is wrong.

The relation between angular momentum, moment of inertia and angular velocity is :

L = Iω

Let L₁ and L₂ be the angular momentum of solid sphere and hollow sphere respectively.

L₁ = I₁ω     and   L₂ = I₂ω

As ω is same for both spheres but I₂ is greater than I₁, hence L₂ is greater than L₁.

Therefore, statement I is correct that the hollow sphere has the greater angular momentum.

Answers

Answer:

The First and Second World Wars dampened enthusiasm for saengerfests in the United States, as anti-German sentiment rose in the midst of these conflicts.

The enthusiasm for saengerfests in the United States waned during the First and Second World Wars.

What led to this?

This decline was primarily attributed to the growth of anti-German sentiment amidst these global conflicts.

As patriotic fervor intensified and tensions escalated, public interest in German cultural events like saengerfests dwindled. The negative perception of German heritage during the wars led to a decrease in participation and support for these traditional celebrations.

Biofertilizers can be made at home, and there are many ways, such as using compost, inoculating, and, after incubation, using the fermentation technique to make the proper biofertilizers.

What is the significance of the biofertilizers?

Biofertilizers are environmentally friendly and they require a series of processes to be formed, such as collecting compost, bacterial cultures, water, and so on, and then properly mixing the mixture, which is then kept for a few days for further fermentation. After this process, it is diluted and applied to the plants.

A designer of soup cans wants to redesign the cans by enlarging the area of the base to three times the original size. The new can should hold the same amount of soup. How should the designer change the height of the can?

Answers

The designer should change the height of the can and maintain the same volume by doubling the area of the base of the can.

How to change the height of the can

Area of a cylinder, V= πr²h

Where:

r= base radiush= height.

Area of the base, A= πr²

So,

volume of the cylinder;

V= A×h

For instance,

if volume of a cylinder is 50cm³ and area of the base is 10cm²

V= A*h

50 = 10 × h

50 = 10h

h = 50/10

h = 5cm

If the area of the base is doubled at a constant volume, that is A = 20cm², V = 50cm²

V= A×h

50 = 20 × h

50 = 20h

h = 50/20

Find the roots for these problem show your work​

Answers

So the roots of the original equation are:

x = 0, x = 1 + √3, x = 1 - √3

Let's solve each of these equations and find their roots.

x⁵ - 4x⁴ - 2x³ - 2x³ + 4x² + x = 0:

To factorize this equation, we can factor out an "x" term:

x(x⁴ - 4x³ - 4x² + 4x + 1) = 0

Now, we have two factors:

x = 0

To find the roots of the second factor, x⁴ - 4x³ - 4x² + 4x + 1 = 0, we can use numerical methods or approximation techniques.

Unfortunately, this equation does not have any simple or rational roots. The approximate solutions for this equation are:

x ≈ -1.2385

x ≈ -0.4516

x ≈ 0.2188

x ≈ 3.4714

x³ - 6x² + 11x - 6 = 0:

This equation can be factored using synthetic division or by guessing and checking.

One possible root of this equation is x = 1.

By performing synthetic division, we can obtain the following factorization:

(x - 1)(x² - 5x + 6) = 0

Now, we have two factors:

x - 1 = 0

x = 1

x² - 5x + 6 = 0

To find the roots of the quadratic equation x² - 5x + 6 = 0, we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

In this case, a = 1, b = -5, and c = 6.

Substituting these values into the quadratic formula, we get:

x = (5 ± √(25 - 24)) / 2

x = (5 ± √1) / 2

x = (5 ± 1) / 2

So the roots of the quadratic equation are:

x ≈ 2

x ≈ 3

Therefore, the roots of the original equation are:

x = 1, x ≈ 2, x ≈ 3

x⁴ + 4x³ - 3x² - 14x = 8:

To solve this equation, we need to move all the terms to one side to obtain a polynomial equation equal to zero:

x⁴ + 4x³ - 3x² - 14x - 8 = 0

Unfortunately, this equation does not have any simple or rational roots. We can use numerical methods or approximation techniques to find the roots.

Approximate solutions for this equation are:

x ≈ -2.5223

x ≈ -0.4328

x ≈ 1.6789

x ≈ 3.2760

x⁴ - 2x³ - 2x² = 0:

To solve this equation, we can factor out an "x²" term:

x²(x² - 2x - 2) = 0

Now, we have two factors:

x² = 0

x = 0

x² - 2x - 2 = 0

To find the roots of the quadratic equation x² - 2x - 2 = 0, we can again use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

In this case, a = 1, b = -2, and c = -2. Substituting these values into the quadratic formula, we get:

x = (2 ± √(4 - 4(1)(-2))) / (2(1))

x = (2 ± √(4 + 8)) / 2

x = (2 ± √12) / 2

x = (2 ± 2√3) / 2

x = 1 ± √3

So the roots of the original equation are:

x = 0, x = 1 + √3, x = 1 - √3
