Atomic theory describes the motion of particles in solids, liquids, and gases. Which statement best describes the particles in a given state of matter?
A. The particles in gases have a fixed position but can vibrate.
B. The particles in solids have a fixed position but can vibrate.
C. The particles in solids are very close to each other but they are able to move past each other. D. The particles in gases are very close to each other but they are able to move past each other.
Answer:
B. The particles in solids have a fixed position but can vibrate
Explanation:
Answer choice "A" is incorrect because particles in gases are not held by bonds and move freely (not fixed).
Answer choice "C" is incorrect because while solids are close in proximity, their particles do not move past each other.
Answer choice "D" is incorrect because while the particles in gases are able to move past each other, they are not arranged in close proximity. In fact, them being spread out and free is why they are able to move past each other.

How do elastic energy, kinetic energy, and gravitational energy differ from each other?
Answer:
Gravitational pulls things to the ground
Elastic is stretched or compressed or a shape or object
Kinetic is kinda like the force of motion
Hope this helps
In the gravitational energy, things are pulled to the ground by gravity, for elastic energy stretched, squeezed, or as a shape or item, and for kinetic energy it is similar to the force of motion.
What is Kinetic energy?Kinetic energy is the term used in mechanics to describe the impulse that an object experiences as it moves. It is described as the amount of effort needed to move someone of a certain mass to rest to a given velocity. Except for fluctuations in speed, the body retains its acceleration after receiving it during acceleration.
The body uses the same lot of fuel when slowing down from its current rate to a state of rest. Formally, kinetic energy refers to any element in the Lagrangian of such a system that seems to have a derivative with respect to time.

Answer: The answer to 3 to is less inertia. The answer to 4 is large amount of inertia. The answer to 5 is large amount of inertia. The answer to 6 is more fuel. Number 6 is kind of unkown considering I can’t see the other answer but I guess it’s more fuel.
Explanation: Inertia is the resistance of the object to any change in its motion, including a change in direction. An object will stay still or keep moving at the same speed and in a straight line, unless it is acted upon by an external unbalanced force. So when there is more inertia, it’s harder to control, but when it has less inertia, it’s more loose and easier to move around.
Hiro walks up a flight of stairs in his apartment building. Later in the day, he runs up the same flight of stairs.
Which statement about work and power describes Hiro’s actions?
He did more work running than walking.
He did more work walking than running.
He had more power running than walking.
He had more power walking than running.
Answer:
C) he had more power running than walking
Explanation:
saw it on a quizlet. not 100% sure tho
Hiro walks up a flight of stairs in his apartment building. Later in the day, he runs up the same flight of stairs so He had more power running than walking.
What is power?In physics, power is the amount of energy transferred or converted per unit of time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.
Power is related to other quantities; for example, the power involved in moving a ground vehicle is the product of the traction force on the wheels and the velocity of the vehicle.
The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft
Since we know that Hiro will run on stairs to minimize the time of reaching his home so if time decreases then he has to increase his power as power is the ratio of work and time.
Hence Hiro walks up a flight of stairs in his apartment building. Later in the day, he runs up the same flight of stairs so He had more power running than walking.

What is radioactivity?The nucleus of an atom exhibits the phenomenon of Radioactivity due to its instability. Energy will be lost due to the emission of radiation from the unstable nucleus of an atom.
The electrostatic force of repulsion and the powerful forces of attraction keep the nucleus together. The instability increases as the size of the nucleus increases because the mass of the nucleus increases when concentrated. Therefore, Plutonium, Uranium is extremely unstable and undergoes radioactivity.
The emitted radiation from radioactivity always consists of alpha, beta, and gamma particles. Gamma Decay is photons having high energy, Beta Decay consists of Electrons while Alpha Decay consists of a Helium nucleus.

A long jumper leaves the ground at an angle of 25 degrees with respect to the horizontal with a resultant velocity of 30 ft/s. What was the horizontal velocity of the jumper at takeoff? What was the vertical velocity at takeoff? How high did the COM rise above the point of takeoff?
Answer:
The horizontal component of the velocity is 27.19 ft/s
The vertical component of the velocity at takeoff is 12.68 ft/s
The vertical distance traveled by the jumper is 8.2 ft
Explanation:
Given;
angle of projection or takeoff, θ = 25°
the resultant velocity, v = 30 ft/s
The horizontal component of the velocity is given by;
[tex]v_x = vcos \theta\\\\v_x = 30 * cos(25)\\\\v_x = 27.19 \ ft/s[/tex]
The vertical component of the velocity at takeoff is given by;
[tex]v_y = vsin \theta\\\\v_y = 30 * sin(25)\\\\v_y = 12.68 \ ft/s[/tex]
The vertical distance traveled by the jumper is given by;
[tex]v_y_f^2 = v_y_o^2 +2(-g)h\\\\v_y_f^2 = v_y_o^2 -2gh\\\\0 = 12.68^2 - (2*9.8)h\\\\0 = 160.78 - 19.6h\\\\19.6h = 160.78\\\\h = \frac{160.78}{19.6}\\\\ h = 8.2 \ ft[/tex]

Answer:
Antibacterial activity
Explanation:
The antibacterial property does not allow bacterias to live in an environment. Many spices have the ability to show antibacterial activity, few of these spices can be named as cinnamon, turmeric, or clove. Because they have antimicrobial or antibacterial characteristics that is why they are used for food preservation, disease prevention, and provide many health benefits. But, not every spice has antibacterial characteristics, that is why Janel experimented with five different spices to see which amongst them possess antibacterial characteristics.
Hence the correct answer is Antibacterial activity.

How do the magnitudes of the baseballs' accelerations32 2at t = 0s compare (do not neglect air resistance)?
Complete Question
The complete question is shown on the first uploaded image
Answer:
The correct option is B
Explanation:
From the question we are told that
The terminal velocity of both balls is [tex]v_t = 32 \ m/s[/tex]
The speed with which ball A is thrown up at t =0 s is [tex]v__A}} = 16\sqrt{2}[/tex]
The speed with which ball B is thrown 30° below the horizontal at t =0 s is
[tex]v__{B}} = 32\sqrt{2}[/tex]
Generally the acceleration of ball A is (g i.e acceleration due gravity)given that it is thrown straight up
Generally the vertical acceleration of ball B is mathematically represented as
[tex]a = gcos (90 - 30)[/tex]
[tex]a = gcos (60)[/tex]
Generally the ratio of both acceleration is
[tex]\frac{a__{{A}}}{a__{{B}}}} =\frac{g}{gsin(60)}[/tex]
=> [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{1}{sin (60)}[/tex]
=> [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{1}{\frac{\sqrt{3} }{2} }[/tex]
=>[tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{2}{\sqrt{3} }[/tex]
Rationalizing
=> [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{2}{\sqrt{3} } *\frac{\sqrt{3} }{\sqrt{3} }[/tex]
=> [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{2 \sqrt{3} }{3}[/tex]
=>[tex]a__{B}} = \frac{2\sqrt{3} }{3} * a__{A}}[/tex]
