The statement given "A chemical process with an e-factor of 1 creates less waste than an E-factor of 25" is True.
E factor :The E factor takes into account all waste that may be classified as trash, including byproduct waste, residual reactants, solvent losses, spent catalysts and catalyst supports, and any other waste that can be classified as waste. The computation is based on the definition of waste. Since water is typically safe and a considerable byproduct of many chemical processes, its bulk is typically excluded from the calculation of the total mass of waste. Higher E values are generally less desirable and 0 is the ideal E factor. The volume of product produced and the product's value determine the e variables that may be tolerated. Tolerable E factors for bulk chemicals generated in quantities ranging from hundreds of thousands to millions of tons per year typically fall between 1 and 5.Learn more about the Green chemistry with the help of the given link:

Any substance or mixture of substances intended for the cure, mitigation, diagnosis, or prevention of disease is a drug.
What is diagnosis?The process of determining which disease or condition is to blame for a person's symptoms and signs is known as medical diagnosis. The term "diagnostic" is most frequently used, with the implied reference to medicine. The history and physical examination of the patient who is seeking medical attention often yield the data needed for diagnosis. The process frequently includes one or more diagnostic procedures as well, such doing medical testing. Posthumous diagnosis is occasionally seen as a type of medical diagnosis.
Due to the vague nature of many symptoms and indicators, diagnosis is frequently difficult. For instance, skin redness (erythema), when present alone, is a symptom of numerous illnesses and cannot be used to diagnose a patient's condition.

Describe a situation in which you can accelerate even though your speed doesn’t change.
Uniform circular motion is an example of this question.
Uniform motion in a circular path defines a uniform circular motion.For a circular motion, the essential condition to be fulfilled is having a centripetal force directed towards the centre of the locus.If not that kind of motion defines a uniform linear motion.According to Newton's second law, when there is a net force there exists an acceleration in the direction of the net force.This acceleration in a circular motion is called the "centripetal acceleration".Since the motion is uniform, its speed remains constant having only the direction of the instantaneous speed changing.Therefore, in that type of motion, there is the situation of no speed change with acceleration.

Someone standing at the edge of a cliff throws one ball straight up and another ball straight down at the same initial speed. Neglecting air resistance, which ball has the greatest final velocity upon reaching the ground?.
Both balls have the same velocity upon reaching the ground.
Each ball is given some kinetic energy at the edge of the cliff that takes one upwards and the other down.Since the launching height is the same for both balls each one possesses some potential energy measured relative to the ground down there.Since the air resistance is neglected there would be no resistive forces acting upon each ball that could draw away some of the energy each ball has and therefore, the mechanical energy of each ball is conserved throughout the flight.So, if one writes the energy equation from the edge of the cliff to the ground, it would yield the following result.[tex]\begin{aligned}\\\small K.E +P.E &=\small K.E_1 +P.E_1\\\\\small \frac{mv^2}{2}+mgh&=\small \frac{mV^2}{2}+0\\\\\small V&=\small \sqrt{v^2+2gh}\end{aligned}[/tex]
The magnitude of the final velocity does not depend on the mass of the ball.Therefore, both balls would have the same velocity at the ground as they are given the same initial speed at the same initial height.#SPJ4

according to coulomb’s law, which has a greater effect on the force of attraction, increasing the magnitude of thecharge of oppositely charged particles or decreasing the distance between the charges? explain your reasoning
According to Coulomb's law distance between the oppositely charged particles will have a greater effect on the force of attraction between them.
The force of attraction is more affected by distance. The electric force of attraction diminishes by 1/r2 as the distance between the charges grows. For instance, since the repulsive force is inverse, if the distance between the two electrons were to double, it would do so by a factor of 4 rather than 2. (because of the square).
To summarize, according to Coulomb's law, the force of attraction will have the greatest dependence on the distance between the two oppositely charged particles rather than growing with the quantity of charged particles.

Find the magnitude of the resultant force and the angle it makes with the positive x-axis. (let |a| = 22 lb and |b| = 16 lb. round your answers to one decimal place.)
Given,
The magnitude of the resultant force is 39.7 N and makes an angle of 49.5° with the x-axis.
The two given forces are vectors, thus they have to be resolved horizontally and vertically to determine their resultant.
So that:
Horizontal component = F Cos θ
Vertical component = F Sin θ
Thus, given that: a = 28 lb at 45° on x & y axis, and b = 12 lb at 30° below x-axis.
i. Resolving the vector horizontally, we have:
horizontal component = 28 Cos 45° + 12 Cos 30°
= 19.80 + 10.39
horizontal component, x = 30.19
ii. Resolving the vectors vertically, we have:
vertical component = 28 Sin 45° + 12 Sin 30°
= 19.80 + 6.0
vertical component, y = 25.80
a. Magnitude of the resultant force, |R| = [tex]\sqrt{x^{2} + y^{2} }[/tex]
= [tex]\sqrt{(30.19)^{2} +(25.80)^{2} }\\\\[/tex]
