Which of these objects could be falling with constant acceleration?
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.
What can you say about the motion of an object if its velocity time graph is a straight line parallel to the time axis
Explanation:
it means its velocity and acceleration is constant. And there is no change in displacement , so the object is not moving.

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.
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.

describe how changing the particles changed the atom
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.

If size of an image is 10 cm and the magnification produced by a mirror is +1, what will be the size of object?
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.
in which state of matter are particles spread farthest apart from another?
Gas particles are farthest apart from eachother.
Solid particles are tightly packed.
Liquid particles are somewhat loose.
Gas particles are rapidly moving and are farthest apart.
:D
Gas particles are spread farther apart from each other.
What is gas and its characteristics?Gas is a state of matter that has no fixed shape and no fixed volume.
Gases have a lower density than other states of matter, such as solids and liquids.
There is a great deal of empty space between particles, which have a lot of kinetic energy and aren't particularly attracted to one another.
The main characteristics of matter are:
(1) they are easy to compress,
(2) they expand to fill their containers, and
(3) they occupy far more space than the liquids or solids from which they form.
In a gas, particles are in continual straight-line motion.
The kinetic energy of the molecule is greater than the attractive force between them, thus, they are much farther apart and move freely of each other.

differences between a pair of scissors and nailcutter
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.

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.

- The school zone in front of your school has a posted speed limit of 25 mi/h, which is about 11 m/s. Let's
examine the stopping of a car in several different situations.
a. The crossing guard holds up her stop sign, and the driver is paying attention well. The car moves at a
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?
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

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
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]
