C) atoms contain subatomic particles.
John Dalton's atomic model was also known as a 'Billiard Ball Model' because he thought that all atoms were just simple spheres, and nothing complex inside.
Answer:3.185KHz
Explanation:
Where
Length (L) = 2.7cm
Speed (V) = 344m/s
Wavelength of the fundamental standing wave: λ = 4L
λ = 4L
Frequency is the rate per second of a vibration constituting a wave.
Frequency is given as:
F= v/ λ
Therefore,
Frequency= v/4λ
Frequency = 1×(344m/s)/4×(2.7cm)
Convert centimetre to meter
100cm= 1m
Convert Hz to kiloHz
1000Hz= 1kHz
Frequency= 3.185KHz
Newton also understood that white light can be separated into its components because each ray of color is deviated by the glass of the prism by a different amount. He realized, for example, that red light is consistently less deviated than violet light.
Answer:
D) liquid and gas
Explanation:
The three main states of matter are:
- Solid: in solids, the molecules are bond together by strong intermolecular forces, so the molecules are not free to move. Therefore, a solid has a definite shape, so it does not take the shape of its container.
- Liquid: in liquids, molecules are not bond together, so they are free to move (still, there are some weak intermolecular forces which keep them close to each other). Since in liquids molecules can slide past each other, they take the shape of the container.
- Gas: in gases, molecules are totally free to move, so gases take the shape (and also the volume) of the container.
Based on the definitions above, we can conclude that the correct answer is
D) liquid and gas
