Decreasing pressure on a gas will cause its volume to increase, as it isn't being forced into a smaller space. Increasing temperature causes the atoms in the gas to contain more energy, making them move around more. This too increases the volume.
So basically both would increase the volume of the gas. Hope this helps
The negative sign on the acceleration is only a vector quantity that means the object is accelerating to the left. Hence, we can only focus on it magnitude which is 4 m/s^2. Acceleration is the change in velocity over time. The change in velocity must be 24 m/s - 0 m/s, if you want the object to stop. Therefore,
a = (v2 - v1)/t
4 = (24 - 0)t
t = 6 seconds
The object will stop after 6 seconds.

Answer:
Orange juice has a lower viscosity than chocolate syrup.
Explanation:
Viscosity is the measure we use to determine essentially how thick a fluid is. So, a liquid that has a high viscosity, is thicker than a liquid that has a lower viscosity. Viscosity is also benchmarked against that of water since water is considered to he the least viscous fluid. Therefore, the more "watery" the substance, the less viscous it is.
Its easy to imagine how orange juice would have a lower viscosity. When we imagine, we think about how quickly both orange juice and chocolate syrup would flow if they both were to be spilled. Basically, we would be looking at their "flow rate" where orange juice would wash away quickly while chocolate syrup would tend to stick to the surface and be slower. But lets also look why this happens. This happens because of the size of the particles. Orange juice is diluted and has a lot of water molecules which are small and can move very quickly. Chocolate syrup on the other hand is comprised of molecules that are larger and heavier and therefore take a longer time to move. So a liquid with lower viscosity is "less resistant to flow".
Answer:
λ= 2455 nm
Explanation:
Constructive interference occurs when the optical path difference is equal to an integer multiple of wavelength. Let's examine the reflection on each face
On the first surface we go from a lower medium refractive index (air) to one with a higher index (film), whereby a phase change of pi (180º) is introduced. On the second surface instead of the beginning of refraction, it is from a higher index to a smaller one, so there is no phase change, with this we can write the normal interference equation.
2 t = (m + ½)
The term lann is the wavelength in the film that is related to the wavelength in the air by
= λ / n
2t = (m + ½) λ / n
λ = 2t n / (m + ½)
For the first constructive interference m = 0
λ = 2 0.448 10⁻⁶ 1.37 / (0 + ½)
λ = 2,455 10⁻⁶ m
λ = 2,455 10⁻⁶ m (10⁹ nm / 1m)
λ= 2455 nm
For m = 1
λ = 2 0.448 10-6 1.37/ (1 + ½)
λ = 0.81835 10-6 m
λ = 818 nm
We can observe that the length and where it corresponds to ultraviolet light, so there is no constructive interference for visible light.
