C) occurs because a force is exerted on the electrons
D) involves the movement of ions as well as electrons
4)The time that it takes for a wave to travel one wavelength is considered a(n) _____.
A) period
B) velocity
C) amplitude
D) rarefaction
(This is for Integrated Physics and Chemisty)
1.
Answer:
A) valence electrons
Explanation:
outer shell electrons used to participate in formation of bonding because when two atoms comes close to each other then these outer shell electrons interact with each other and hence bond will form between the atoms.
So correct answer will be
A) Valence Electrons
2.
Answer:
More energy than reactants
Explanation:
Here products will have more energy than reactants due to which overall the energy is released and hence we get some energy along with the products in such type of reactions.
3.
Answer:
C) occurs because a force is exerted on the electrons
Explanation:
Static charge will remains at rest because of the the force that makes them in stationary condition.
4.
Answer:
A) Period
Explanation:
One time period is the total time for which a one complete wavelength distance is traveled by the wave.
Neon gas
Arrange the substances in the table from the MOST to the LEAST ordered particle arrangement
A)
wood, water, neon gas
B)
wood, neon gas, water
water, wood, neon gas
D
water, neon gas, wood
Answer:
I think the correct answer from the choices listed above is option A. The correct arrangement of the substances according to the most to the least ordered particle arrangement should be wood, water and neon gas. Wood should be the first since it is solid which has the most ordered structure as compared to the liquid and a gas. The neon gas is the last since as a gas it has the least ordered structure.
Answer:
A) wood, water, neon gas
Explanation:
wood, water, neon gas.
The particles of solids have an arrangement that is highly ordered and regular. Liquids have an arrangement that is less ordered, and the particle arrangement in gases is the least ordered and regular of the three states of matter.
tell me if im wrong .... hope this helps :)
.1 nano ampere
Explanation:
I= Q flow/ t in secs
I= 233/2700
I= 0.0862e/sec
I= 0.0862/6.25 * 10^8 ( ampere conversion)
I= 0.1 nano ampere .
Sound can be best described as a mechanical wave and a disturbance in matter that is transmitted from its source outward. This disturbance can move in the form of periodic waves or longitudinal waves. The speed, frequency, and wavelength of a sound are interconnected and sound requires a medium to propagate.
Sound is best described as a mechanical wave, a type of disturbance in matter that is transmitted from its source outward. This movement can be in the form of periodic or longitudinal waves, implying that they move matter back and forth in the direction of the wave's motion. The speed of sound, its frequency, and its wavelength are interconnected, and this is described mathematically by the relationship v = fλ. This relationship shows that the velocity of sound (v) equates to the frequency (f) multiplied by the wavelength (λ).
Sound waves can be both audible and inaudible, originating from various sources, ranging from musical instruments to vocal voices to explosive bangs like a sonic boom. Also, to note is that sound is interpreted through our sense of hearing, and different frequencies and intensities create different sounds. Sound also has the ability to travel through different mediums, including solids, liquids, and gases, with varying speeds.
On a microscopic level, sound can be seen as synchronized oscillation of atoms. This type of motion is more organized than the thermal motion of the atoms. The behavior of sound waves is significantly different from light waves, as sound requires a medium to propagate, while light can travel in a vacuum.

A. Displacement
O B. Time
C. Acceleration
D. Average speed
To calculate velocity in Physics, the two necessary measurements are displacement and time. Velocity is the speed in a specified direction, determined by dividing displacement by time.
In the field of Physics, the two measurements needed to calculate the velocity of an object are displacement and time. Velocity refers to the speed in a given direction and is calculated by dividing displacement (which gives direction information and distance) by the time it takes to move that distance. For example, if an object traveled 100 meters to the north in 20 seconds, the velocity would be 5 meters per second towards the north.
