The final rotational speed ω_final and the instantaneous power P delivered to the wheel are; ω_f = √((ω_i)² + 2(FL/(kmr²) and P = Frω_i
What is the Instantaneous Power?A) From rotational kinematics, the formula for the final angular velocity is;
ω_f = √((ω_i)² + 2αθ)
where;
α is angular acceleration
θ = L/r. Thus;
ω_f = √((ω_i)² + 2α(L/r))
Now, α = T/I
Where;
I is moment of inertia = k*m*r²
T is t o r q u e = F * r
Thus;
α = (F * r)/(kmr²)
α = F/(kmr)
ω_f = √((ω_i)² + 2(F/(kmr))(L/r))
ω_f = √((ω_i)² + 2(FL/(kmr²)
B) Formula for instantaneous power is;
P = Fv
where at t = 0; v = rω_i
Thus;
P = Frω_i

The loudness, l, measured in decibels (db), of a sound intensity, i, measured in watts per square meter, is defined as , where and is the least intense sound a human ear can hear. what is the approximate loudness of a rock concert with a sound intensity of 10–1? 2 db 22 db 60 db 110 db
Using the loudness formula, it is found that the approximate loudness of a rock concert with a sound intensity of [tex]10^{-1}[/tex] is of 110 dB.
What is the loudness formula?It is given by:
[tex]L = 10\log{\left(\frac{l}{l_0}\right)}[/tex]
In which [tex]l = 10^{-12}[/tex] is least intense sound a human ear can hear and l is the intensity.
In this problem, we have that the intensity is of [tex]l = 10^{-1}[/tex], hence:
[tex]L = 10\log{\left(\frac{l}{l_0}\right)}[/tex]
[tex]L = 10\log{\left(\frac{10^{-1}}{10^{-12}}\right)}[/tex]
[tex]L = 10\log{10^{11}}[/tex]
L = 10 \times 11
L = 110 dB.

According to the question, A GMO is a plant is one that has had its DNA changed using technology. Therefore option B is correct.
What is GMO Plant?Plants can be genetically modified by inserting a particular DNA sequence into their genome to confer new or different traits. This can entail altering the plant's growth pattern or conferring disease resistance on it.
Today's GMO crops were primarily created to aid farmers in reducing crop loss. The following are the top three characteristics of GMO crops:
A defense against insect harm
Herbicide tolerance
Virus-resistant plants
The most popular GMO crops were created to meet the demands of farmers, but they can also help make food more readily available and less expensive for consumers.

An average light bulb manufactured by the acme corporation lasts 300 days with a standard deviation of 50 days. assuming that bulb life is normally distributed, what is the probability that an acme light bulb will last at most 365 days?
Answer:
1. 90% 2. 10% 3. 50%
Explanation:
Given a mean score of 300 days and a standard deviation of 50 days, we want to find the cumulative probability that bulb life is less than or equal to 365 days. Thus, we know the following:
The value of the normal random variable is 365 days.
The mean is equal to 300 days.
The standard deviation is equal to 50 days.

Considering your answer to part (b), explain why h2o(l) has a measurable equilibrium vapor pressure at 298k.
Water (H₂O) has a measurable equilibrium vapor pressure at a temperature of 298 Kelvin because it changes into the vapour state (gaseous).
What is vapor pressure?Vapor pressure can be defined as as a measure of the pressure which is exerted by a vapor that is in thermodynamic equilibrium with its liquid or solid form (condensed phases), especially due to a specific temperature in a closed system.
This ultimately implies that, the vapor pressure of a cehemical compound such as water (H₂O) has an exponential relationship with temperature. Consequently, the vapor pressure of water (H₂O) would always increase as temperature increases, as well.

A sample of manufactured items will be selected from a large population in which 8 percent of the items are defective. of the following, which is the least value for a sample size that will allow for the sampling distribution of the sample proportion to be assumed approximately normal?
The sample size required should be at least of size 30.
According to the Central limit theorem, if from an unknown population large samples of sizes n ≥ 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
\mu_{\hat p}=pμp^=p
The standard deviation of this sampling distribution of sample proportion is:
\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}σp^=np(1−p)
Here it is provided that manufactured items are selected from a large population in which 8% of the items are defective.
That is, the proportion of defective items is, p = 0.08.
For the sampling distribution of the sample proportion of defective items to be normally distributed the least sample size required is 30.
Thus, the sample size required should be at least of size 30.

The work done by Chase in pushing the boulder over the given distance is 414J.
Work done
Work is simply the measure of energy transfer that takes place when an object is pulled or pushed by an external force over a given distance.
It is expressed as;
W = F × d
Where F is force applied d is the displacement.
Given the data in the question;
Mass of boulder m = 210kgForce applied F = 180N = 180kgm/s²Distance covered d = 2.3mWork done W = ?To determine the work done by Chase, we substitute our given values into the expression above.
W = F × d
W = 180kgm/s² × 2.3m
W = 414kgm²/s²
W = 414J
Therefore, the work done by Chase in pushing the boulder over the given distance is 414J.
