A. 3 hours

B. 12 hours

C. 6 hours

D. 4 hours

Answers

Answer:

100,000 / 800,000 = 1 / 8    amount of sample after 12 hours

(1/2)^n = 1 / 8      after n half-lives 1/8 of sample will be left

n = 3

(D) is the correct answer - 1/2 half-life = 4 hours

If we want to get an estimate for the average distance from the sun to a planet, how might we go about doing this? (Choose one answer):

1. By measuring the eccentricity of the orbit, which is directly
related to the size of the orbit's ellipse and hence the distance
from the sun.

2. Measure its orbital period (the time it takes to complete a
single orbit) because Kepler's third law allows us to calculate
the orbit's semi-major axis from this.

3. This cannot be done without sending a probe to the planet.
We have done this for some planets already, but not others.

Answers

The distance between the sun and a planet can be gotten by measuring its orbital period and applying the Kepler's law.

Kepler's laws

According to Keplers third law; the cube of the distance between a planet and the sun is directly proportional to the square of the period of the same planet.

Having said that, we know that we can best measure the distance between the sun and a planet by measuring its orbital period and applying the Kepler's law.

Answers

Answer:

The answer is increases.

Explanation:

When positive charge is shifted from a low potential to a high potential region, the electric potential energy increases.

Explanation:

The correct sequence that shows the units of matter from smaller to largest is option A, protons, atoms, rock particles , bricks and buildings.

What are units of matter ?

The basic units of matter is called atoms. These atoms are made of subatomic particles namely, protons, electrons and neutrons. The protons and neutrons  are located inside nucleus and the electrons are revolving around.

Every substance in the universe are made of atoms. Atoms of different elements combines to form compounds. Different  solid compounds and molecules deposits to forms rocks.

Rocks can be molded to bricks and other shapes they are then used to construct buildings. Therefore, the correct sequence of the units of matter from smallest to largest is protons, atoms, rocks, bricks and buildings.

A bus is traveling at 25 m/s, and a cyclist is traveling at 5 m/s behind the bus, in the same direction. the frequency of a sound coming from the bus is observed by the cyclist to be 1000 hz. approximately what is the frequency of the sound as perceived by the bus driver

Answers

Answer:

Approximately [tex]1061\; {\rm Hz}[/tex] (rounded to the nearest whole number,) assuming that the speed of sound in the air is [tex]330\; {\rm m \cdot s^{-1}}[/tex].

Explanation:

Let [tex]v[/tex] denote the speed of this sound wave: [tex]v = 330\; {\rm m\cdot s^{-1}}[/tex] by assumption.

Let [tex]\Delta v[/tex] denote the speed at which the source (the bus) moves away from the observer (the cyclist.) In this question, [tex]\Delta v = 25\; {\rm m\cdot s^{-1}} - 5\; {\rm m\cdot s^{-1}} = 20\; {\rm m\cdot s^{-1}}[/tex].

Let [tex]d[/tex] denote the distance between the source (the bus) and the observer (the cyclist) when the first crest leaves the source. At a speed of [tex]v[/tex], it would take [tex]d / v[/tex] before the first crest arrive at the observer.

Let [tex]T[/tex] denote the period of this wave. If a crest of this wave leaves the source at [tex]t = 0[/tex], the very next one would leave at [tex]t = T[/tex]. Since the source is moving away from the observer at [tex]\Delta v[/tex], the distance between the two would have since increased from [tex]d[/tex] to [tex](d + \Delta v\times T)[/tex]. At a speed of [tex]v[/tex], this crest would now need [tex](d + \Delta v\times T) / v[/tex] to reach the observer.

In summary:

The first crest leaves the source at [tex]t = 0[/tex] and arrives at the observer at [tex]t = d / v[/tex].The second crest leaves the source at [tex]t = T[/tex] and arrives at the observer at [tex]t = T + (d + \Delta v\times T) / v[/tex].

The time difference between the two crests is [tex]T[/tex] at the source. However, at the observer, this difference would have become:

[tex]\begin{aligned} &T + \frac{d + \Delta v\times T}{v} - \frac{d}{v} \\ =\; & T + \frac{\Delta v\times T}{v} \\ =\; & T\times \frac{v + \Delta v}{v}\end{aligned}[/tex].

Therefore, the ratio between the period at the source and at the observer would be:

[tex]\begin{aligned}\frac{T(\text{observer})}{T(\text{source})} &= \frac{\displaystyle T \times \frac{v + \Delta v}{v}}{T} \\ &= \frac{v + \Delta v}{v}\end{aligned}[/tex].

The frequency [tex]f[/tex] of a wave is equal to the reciprocal of its period [tex]T[/tex]. In other words, [tex]f = (1 / T)[/tex]. Therefore:

[tex]\begin{aligned}\frac{f(\text{observer})}{f(\text{source})} &= \frac{T(\text{source})}{T(\text{observer})} \\ &= \frac{v}{v + \Delta v}\end{aligned}[/tex].

Since [tex]f(\text{observer}) = 1000\; {\rm Hz}[/tex], [tex]\Delta v = 20\; {\rm m\cdot s^{-1}}[/tex], and [tex]v = 330\; {\rm m\cdot s^{-1}[/tex] by assumption:

[tex]\begin{aligned} & f(\text{source})\\ =\; & f(\text{observer}) \times \frac{v + \Delta v}{v} \\ =\; & 1000\; {\rm m\cdot s^{-1}} \times \frac{330\; {\rm m\cdot s^{-1}} + 30\; {\rm m\cdot s^{-1}}}{330\; {\rm m\cdot s^{-1}}} \\ \approx\; & 1061\; {\rm m\cdot s^{-1}}\end{aligned}[/tex].

The true statement is "Falsifiable by experimental testing or observations." The correct option is 1.

What is a new hypothesis?

In science, a hypothesis is a proposed explanation or prediction for a phenomenon or set of observations.

A new hypothesis is a fresh idea put forth by a scientist to explain a phenomenon or observation that has not been explained or understood fully by existing scientific theories or hypotheses.

The new hypothesis should be based on previous knowledge and observations, and it should be testable and falsifiable through experiments or observations. Scientists use hypotheses to guide their research and develop theories, which are more comprehensive explanations backed up by multiple lines of evidence.

Therefore, only Option (1) is the correct answer.
