What's the answer to this question?​

Answers

Answer:

The barometer is supporting 75 cm of Hg due to atmospheric pressure.

Since the manometer is open to air pressure, the gas pressure is supporting the air pressure plus the 30 cm of Hg.

So the "absolute" gas pressure is 75 + 30 = 105 cm of Hg.

Which pair of quantities represent scalar quantities, and how are they different from vector quantities?

A. energy and velocity

B. displacement and velocity

C. displacement and time

D. distance and time

Answers

D.

They don't have directions.

The quantities with only magnitude and no direction are called scalar quantities. Therefore, option D is the correct answer.  

Scalar quantities have only magnitude but vector quantities have both magnitude and direction. Some examples of scalar quantities are,

• Mass

• Temperature  

• Speed

• Density

Thus, we conclude that the quantities with only magnitude and no direction are scalar quantities. Hence option D is the correct pair.

describe how changing the particles changed the atom​

Answers

Answer: During chemical changes particles do change with atoms or ions regrouping . Bonds (links) between atoms break and new ones form and energy is either given out or taken in.

Explanation:

Chemical reactions make particles to change and resulting to change atoms or ions via regrouping .

What is chemical reaction?

The chemical reaction is the reaction between two reactants that led to the formation of products.

The products are substances that forms after reaction. The reactants are the substances which are original materials.

Bonds between atoms break and make new ones. In this process, energy is either rejected or taken in.

The particle are the electrons which are shared between the atoms of same or different elements.

The electrons in the valence get donated or accepted by the atoms and form bond. When the electrons are donated, the bonds break and when electrons are accepted, bonds are formed. So, the new element or compound is formed.

Thus, the chemical reaction are responsible for change in atoms due to change in particles.

explain at least two differences between justice system laws and scientific laws.

Answers

The adversarial system is rigid – the roles are proscribed – the prosecutor wants to convict, the defendant wants a decision of not guilty. They are not just allowed but expected to bias their presentation, trusting the truth to come out between the adversaries. Science certainly has its sides of partisanship and bias. But these sides are self-imposed and can be abandoned at any time. While a prosecutor should not lie or hide evidence, and should drop a case if they become convinced the defendant is innocent, they wake up in the morning with no choice about which side of the argument they will come down on. In the criminal justice system the advocates are rigidly fixed in their roles and the jurors are rigidly neutral (the process to find a random neutral jury took as long as the trial itself). In science, the advocates are the same people as the jurors. And as a result they have to be willing to be flexible and change their minds. A good scientist shouldn’t have a pre-determined rigid answer to a question.
Lack of investigation – we jurors were told over and over not to investigate the situation ourselves. We were to make our decision only on the basis of the evidence presented to us. I can tell you in the case I was on there were at least two whopping big questions hanging over the case that nearly every juror in the room identified as very important but not addressed by either lawyer. Either one of them (whether the defendant’s schedule allowed time to drink before being stopped in the car, whether a particular medical condition could affect breathalyzer tests) could have changed the outcome. We could have answered one of these with 10 minutes on google and the other with some very simple subpoena of records. But we couldn’t use any of this. Scientists obviously are the opposite – if they need more information, they are expected to go get it before making an opinion.
Reliance on personal testimony – although science and trials share a focus on evidence, trials recognize testimony of individual people under oath as a major form of evidence. They certainly acknowledge the possibility of lying and explicitly instruct jurors to decide what testimony they believe. My case was unusual in that there was so much video footage, but still a majority of the case came down to testimony by the police officers, and most cases even a few years ago would have had only testimony. Science on the other hand, doesn’t accept testimony. Or does it? What else is the methods and results section of a paper? I’m on the fence whether science is so different on this one.

Which of these objects could be falling with constant acceleration?

Answers

Answer:

1 and 2

Explanation:

If an object has constant acceleration, it's displacement at time t is:

Δx = v₀ t + ½ at²

For object 1:

0.44 = (0) (0.3) + ½ a (0.3)²

a = 9.78

3.14 = (0) (0.8) + ½ a (0.8)²

a = 9.81

So object 1's acceleration is approximately constant.

For object 2:

0.06 = (0) (0.3) + ½ a (0.3)²

a = 1.33

3.09 = (0) (2.1) + ½ a (2.1)²

a = 1.40

So object 2's acceleration is approximately constant.

For object 3:

0.44 = (0) (0.3) + ½ a (0.3)²

a = 9.78

3.09 = (0) (2.1) + ½ a (2.1)²

a = 1.40

So object 3's acceleration is not constant.

Explain why there is a delay between the arrival of the sound transmitted through the steel pipe and the sound transmitted by the air in the pipe.​

Answers

Answer: RATE ME AND MAKE ME BRAININESS AND THANK ME

Explanation:Sound waves are pressure waves that travel through Earth's crust, water bodies, and atmosphere. Natural sound frequencies specify the frequency attributes of sound waves that will efficiently induce vibration in a body (e.g., the tympanic membrane of the ear) or that naturally result from the vibration of that body.

Sound waves can potentiate or cancel in accord with the principle of superposition and whether they are in phase or out of phase with each other. Waves of all forms can undergo constructive or destructive interference. Sound waves also exhibit Doppler shifts—an apparent change in frequency due to relative motion between the source of sound emission and the receiving point. When sound waves move toward an observer the Doppler effect shifts observed frequencies higher. When sound waves move away from an observer the Doppler effect shifted observed frequencies lower. The Doppler effect is commonly and easily observed in the passage of planes, trains, and automobiles.

The speed of propagation of a sound wave is dependent upon the density of the medium of transmission. Weather conditions (e.g., temperature , pressure, humidity , etc.) and certain geophysical and topographical features (e.g., mountains or hills) can obstruct sound transmission. The alteration of sound waves by commonly encountered meteorological conditions is generally negligible except when the sound waves propagate over long distances or emanate from a high frequency source. In the extreme cases, atmospheric conditions can bend or alter sound wave transmission.

The speed of sound in steel is about 17 times as fast as it's speed in air.

Naturally, when a sound starts out at one end of a pipe, it reaches the other end thru the steel before it reaches the other end thru the air in the pipe.

The longer the pipe is, the longer will be the delay between the arrival of the two sounds at the other end.

The acceleration due to gravity on the Moon is gM. Suppose an astronaut on the Moon drops an object from a height of H. The time it would take the object to reach the Moon’s surface would be TM. The same object is dropped from the same height on Earth, where the acceleration due to gravity is gE. The time it takes the object to reach the Earth’s surface is TE. Which of the following is a correct mathematical relationship for the two times?
TE=gEgM−−−√TM

TE=gEgMTM
A

TE=gMgE−−−√TM

TE=gMgETM
B

TE=gEgMTM

TE=gEgMTM
C

TE=gMgETM

TE=gMgETM
D

TE=TM

Answers

The relationship between the two times is [tex]TE = TM\sqrt{\frac{gM}{gE} }[/tex]

The given parameters:

the acceleration due to gravity on the Moon = gM

height from which the object was dropped on moon, =  H

time taken for the object to reach the moon surface, = TM

height from which the object was dropped on Earth, =  H

the acceleration due to gravity on the Earth = gE

time taken for the object to reach the Earth's surface = TE

To find:

The relationship between the two times:

Apply the following kinematic equation:

[tex]H = ut + \frac{1}{2} gt^2\\\\we \ know \ nothing \ about \ the \ initial \ velocity \ u , let \ u = 0\\\\H = \frac{1}{2} gt^2\\\\[/tex]

Height equation for the object on the moon:

[tex]H = \frac{(gM) TM^2}{2}[/tex]

Height equation for the object on the Earth:

[tex]H = \frac{(gE) TE^2}{2}[/tex]

Since the two heights are equal, set the two equation to be equal to each other to determine the relationship between the two times:

[tex]\frac{(gE)TE^2}{2} = \frac{(gM)TM^2}{2} \\\\(gE)TE^2 = (gM)TM^2\\\\make \ TE \ the \ subject \ of \ the \ formula;\\\\ TE^2 = \frac{(gM)TM^2}{gE} \\\\TE= \sqrt{\frac{(gM)TM^2}{gE} } \\\\TE = TM\sqrt{\frac{gM}{gE} }[/tex]

Thus, the relationship between the two times is [tex]TE = TM\sqrt{\frac{gM}{gE} }[/tex]

If size of an image is 10 cm and the magnification produced by a mirror is +1, what will be the size of object?

Answers

Answer:

h = 10 cm

Explanation:

The magnification produced by a mirror is given by :

[tex]m=\dfrac{h'}{h}[/tex]

h' is the image size and h is the object size

We have, h = 10 cm, m = +1

So,

[tex]m=\dfrac{h'}{h}\\\\h=\dfrac{10}{1}\\\\h=10\ cm[/tex]

So, the size off the object is same as that of the size of the image i.e. 10 cm.

differences between a pair of scissors and nailcutter​

Answers

Answer:

Different classes of levers

Explanation:

The main difference between a pair of scissors and nailcutters is that they are different classes of levers. Scissors are made from two class 1 levers, meaning that the effort is exerted at one end and the load at the other with the fulcrum in the middle. This is because we press one end together (the handles) so we are applying the effort, and the other side closes from the fulcrum in the middle.

Nailcutters on the other hand, consist of two class 2 levers. This means that the fulcrum is on the opposite end to the effort with the load in the middle. This is because we press down on one side and the two parts move closer together.

constant velocity of 11 m/s for 2.3 seconds while the driver reacts, then slows down at a constant rate
of -4.5 m/s2. What is the stopping distance for the car in this situation?​

Answers

Answer:

s = 38.7 m

Explanation:

First we calculate the distance covered during uniform motion of reaction time.

s₁ = vt

where,

s₁ = distance covered during uniform motion = ?

v = uniform speed = 11 m/s

t = time = 2.3 s

Therefore,

s₁ = (11 m/s)(2.3 s)

s₁ = 25.3 m

Now, we calculate the distance covered during decelerated motion:

2as₂ = Vf² - Vi²

where,

a = deceleration = -4.5 m/s²

s₂ = distance covered during decelerated motion = ?

Vf = Final Velocity = 0 m/s

Vi = Initial Velocity = 11 m/s

Therefore,

2(-4.5 m/s²)s₂ = (0 m/s)² - (11 m/s)²

s₂ = (-121 m²/s²)/(-9 m/s²)

s₂ = 13.4 m

the total distance will be:

s = s₁ + s₂

s = 25.3 m + 13.4 m

s = 38.7 m
