Answer:
exothermic
Explanation:
An exothermic reaction is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy.
Particles become farther apart from each other in the change of state between liquid and gas.
Hope that helped =)
Answer:
Explanation:
given,
diameter of inlet = 11.2 cm
r₁ = 5.6 cm
r₁ = 0.056 m ∵ 1 cm = 0.01 m
speed of inlet = 5 m/s
diameter of outlet = 17.5 cm
r₂ = 8.75 cm
r₂ = 0.0875 m ∵ 1 cm = 0.01 m
speed of outlet = ?
using continuity equation
A₁ v₁ = A₂ v₂
π r₁² v₁ = π r₂² v₂
Velocity of liquid at the outlet of the tube is equal to 3.2 m/s
These cases are rare, but what happens is something called an occluded front. There are so many things that could be talked about and results aren't typically constant, so I recommend you look up what an occluded front is. Its basically when a cold front catches up to a warm front and forces even more warm air up, causing high amounts of precipitation.
Answer:
Explanation:
<u>Average Speed</u>
The speed of an object is the rate of change of its distance. When an object travels at different speeds over time, the average speed is usually calculated to represent the whole travel.
The average speed is the total distance (d) traveled by the object divided by the elapsed time to cover that distance (t):
The airplane covers a distance of d=1200 m in t=90 s. The average speed is:
