A piece of machinery with a moment of inertia of 2.5 kg-m? rotates with a constant angular speed of 4.0
rad/s. A bolt loosens, causing a part of it to shift outward from the rotation axis, increasing the moment
of inertia by 1.0 kg-m². What would the new angular speed of the machinery be? (hint: Conservation
of momentum) 10 rad/s

Answers

For a piece of machinery with a moment of inertia of 2.5 kg-m, new angular speed is mathematically given as

wf= 2.857 rad/s

What would the new angular speed of the machinery be?

Generally, the equation for the final angular speed  is mathematically given as

wf =  wi*(I1/I2)

Therefore

wf = 4.0*(2.5/3.5)

wf= 2.857 rad/s

In conclusion, the new angular speed

wf= 2.857 rad/s

Almost every solid surface in the Solar System is covered with __________, most of which formed during a period of heavy bombardment. Group of answer choices

Answers

We can confirm that almost every solid surface in the Solar System is covered with craters.

Why are there so many craters?

This is due to the chaotic nature of the way the planets, moons, asteroids, comets, etc formed during the early life of the universe and for many eons since then.  As stated in the question, this was a time of heavy bombardment, meaning each of these objects was being pelted with debris from nearby collisions on a continuous basis.

Therefore, we can confirm that almost every solid surface in the Solar System is covered with craters.

Two moles of helium gas initially at 321 K
and 0.42 atm are compressed isothermally to
1.83 atm.
Find the final volume of the gas. Assume
that helium behaves as an ideal gas. The
universal gas constant is 8.31451 J/K·mol.
Answer in units of m^3

Answers

If the helium behaves as an ideal gas, its final volume is 0.13m³.

Ideal Gas Law

The ideal gas law states "that pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature of gas. It is expressed;

PV = nRT

Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant.

Given the data in the question;

Amount of helium gas; n = 2molTemperature T = 321KPressure P = 0.42atm = 42556.5PaUniversal gas constant R = 8.31451 J/K·mol = 8.31451 m³Pa/KmolVolume V = ?

To determine the volume of the helium gas, we substitute our given values into the expression above.

PV = nRT

V = nRT / P

V = ( 2mol × 8.31451 m³Pa/Kmol × 321K ) / 42556.5Pa

V = 5337.91542m³Pa / 42556.5Pa

V = 0.13m³

Therefore, if the helium behaves as an ideal gas, its final volume is 0.13m³

D. 3 hours or more

Explanation:

The average 8- to 18-year-old spends at least D. 3 hours every day in front of a screen, performing little to no physical activity. This is because, instead of exercising and socializing with their peers, children and teenagers frequently talk, watch a lot of movies/shows, or play video games on their computers.

A pan of water is heated from 23°C to 78°C. What is the change in its temperature on the Kelvin and Fahrenheit scales?

Answers

The change in the temperature of the pan of water on the Kelvin and Fahrenheit scales is 328.15K and 131°F respectively.

Temperature Scale

Temperature scale is simply the methodology of calibrating the physical quantity of temperature.

There are 3 main temperature scales, namely; Celsius, Fahrenheit, and Kelvin.

The expression for conversion are;

Celecius to Kelvin : 0°C + 273.15 = 273.15KCelecius to Fahrenheit : (0°C × 9/5) + 32 = 32°F

Given the data in the question;

Initial temperature of pan I = 23°CFinal temperature of pan F = 78°C

First we determine the change in temperature.

ΔT = Final temperature - Initial temperature

ΔT = 78°C - 23°C

ΔT = 55°C

The change in temperature on the Kelvin scale

ΔT = 55°C = 55°C + 273.15 = 328.15K

The change in temperature on the Fahrenheit scale

ΔT = 55°C = (55°C × 9/5) + 32 = 131°F

Therefore, the change in the temperature of the pan of water on the Kelvin and Fahrenheit scales is 328.15K and 131°F respectively.

the change in the temperature of the pan of water on the Kelvin and Fahrenheit scales is 328.15K and 131°F respectively.

Answers

Answer:

Gina is not correct, she is not using digital signals to share the information.

Explanation

Looking at the question carefully, the type of information shared by Gina is words (when she reads to her friends) and images that she shared with her friends later on. Therefore, neither of the information she shared is discrete(0 and 1) to represent information.

Hence, we can say that Gina is not correct, she is not using digital signals to share the information.

A light ray moving from oil (n=1.38) into an unknown material. If the light is incident at 35 and refracts at 23, what is the index of refraction in the unknown material?

Answers

The index of refraction of the unknown material in which a ray of light is incident at 35° and refracted at 23° is 2.03

Snell's law

index of refraction (n) = Sine i / Sine r

n = Sine i / Sine r

Where

i is the angle of incidence r is the angle of refraction How to determine the refractive index

From the question given above, the following data were obtained:

Index of refraction of oil (nₒ) = 1.38Angle of incidence (i) = 35°Angle of refraction (r) = 23°Index of refraction of unknown material (nᵣ) =?

nₒSine i = nᵣSine r

1.38 × Sine 35 = nᵣ × Sine 23

Divide both side by Sine 23

nᵣ = (1.38 × Sine 35) / Sine 23
