A bicycle has wheels that are 60 cm in diameter. What is the angular speed of these wheels when it is moving at 4. 0 m/s?

Answers

Answer 1

Answer:

ω = 13.33 rad/s

Explanation:

Applying,

v = ωr......................... Equation 1

Where v = linear speed, ω = angular speed and r = radius.

Note that,

r = d/2................. Equation 2

Where d = diameter of the wheel.

Substitute equation 2 into equation 1

v = ωd/2............... Equation 3

make ω the subject of the equation

ω = 2v/d................ Equation 4

Given: v = 4 m/s, d = 60 cm = 0.6 m

Substitute these values into equation 4

ω = 2(4)/0.6

ω = 13.33 rad/s

How many subsets with an odd number of elements does a set with 14 elements have?

Answers

The number of subsets is an illustration of combination

The set with 14 elements have 8192 subsets with an odd number of elements

How to determine the number of subsets?

The number of elements in the set is:

n = 14

The odd numbers less than or equal to 14 are:

Odd = 1, 3, 5, 7, 9, 11, 13

The number of subsets is then calculated as:

Subsets = 14C1 + 14C3 + 14C5 + 14C7 + 14C9 + 14C11 + 14C13

Evaluate the combination expressions

Subsets = 14 + 364 + 2002 + 3432 + 2002 + 364 + 14

Evaluate the sum

Subsets = 8192

Hence, the set with 14 elements have 8192 subsets with an odd number of elements

The law of cosines is used to determine the third side of a triangle

The length of the missing side is 9.3

How to determine the length of the missing side

The complete question is an illustration of the law of cosines

The law of cosine states that:

a^2 = b^2 + c^2 - 2bc * cos(A)

From the complete question (see attachment), we have:

b = 15, c = 13 and Angle A = 38 degrees.

So, the equation becomes

a^2 = 15^2 + 13^2 - 2 * 15 * 13 * cos(38)

Evaluate the exponents

a^2 = 225 + 169 - 2 * 15 * 13 * cos(38)

Evaluate the product

a^2 = 225 + 169 - 307.3

Evaluate the sum and the difference

a^2 = 86.7

Take the square root of both sides

a = 9.3

Hence, the length of the missing side is 9.3

Explanation:

An animal is born with a shorter tail. This makes no difference to its ability to survive or reproduce, but as a result of pure luck, the animal survives, reproduces, and passes its shorter tail down to its offspring. Over time, the species develops a shorter tail. What type of process is described in this scenario?

Answers

Answer:

Recessive alleles are the alleles that get masked and dominant are the traits that get expressed. The short tail of the animal is a recessive trait. Genetic drift is described in the scenario.

What is Genetic drift?

The alteration of the frequency of the existing allele for a specific trait with another or the recessive due to random sampling is called genetic drift.  The sample allele plays a role in the determination of the survival rate and the reproduction rate of the organisms.

Natural selection is the process of choosing the organism with the better trait qualities that can survive and reproduce in the altered environment, while artificial selection is the man-made selection.

Genetic modification is the manipulation of the genes or the genetic material of the organisms either naturally by mutation or through genetic engineering by humans. So, the adaptation of the short tail in the organism is not genetic modification.

Therefore, the process of genetic drift is explained in this scenario.

The density of water is 1000 kilograms per cubic meter, and the density of ice is about 916 kilograms per cubic meter. If 575 kilograms of water and 275 kilograms of ice is combined in a container, about how much volume would the mixture take up?

Answers

Answer:

volume of the mixture is (0.575+0.300)-----> 0.875 m³

Explanation:

we know that

density=mass/volume--------> volume=mass/density

step 1

find the volume of water

mass=575 kg

density of water=1000 kg/m³

volume of water=mass/density-----> 575/1000----> 0.575 m³

step 2

find the volume of ice

mass=275 kg

density of ice=916 kg/m³

volume of ice=mass/density-----> 275/916----> 0.300... m³

the volume of water is 0.575³

the volume of ice is 0.300.. m³

volume of the mixture is (0.575+0.300)-----> 0.875 m³

If the volume occupied by the gas molecules shown below were doubled, what would happen to the pressure they exert? (assume constant temperature. )

Answers

In a gas molecule, If the volume occupied by the gas is doubled, the pressure of the gas exerted would also be doubled.

To approach this question, we need to understand the concept of Boyle's Law.

What is Boyle's Law?

Boyle's Law states that at a constant temperature, the pressure of a gas varies inversely proportional to the volume of the gas. Thus, as the pressure of the gas decreases, the volume of the gas in the container also decreases, vice versa.

Mathematically;

[tex]\mathbf{=P \alpha \dfrac{1}{V}}[/tex]

PV = K

So, in a gas molecule, If the volume occupied by the gas is doubled, the pressure of the gas exerted would also be doubled.
