Plz help me and my lil sis suck at sience :P
Answer:
It is translucent
Explanation: i put it and got it right
B. remains constant
C. increases
D. decreases
1 m/s2
4 m/s2
2 m/s2
Answer :
a = 1 m/s^2
Explanation:
Given information
Net force is a constant
The mass of the truck is
Initial acceleration = 2 m/
The mass of the truck is increased twice as much
= ma
= a
a=
a = 2/2
a = 1 m/
This is a conceptual problem, I’ll try to upload a picture:
Water pipes can burst during very cold winters due to a phenomenon known as "freeze-thaw cycle." When temperatures plummet, water inside the pipes can freeze, causing it to expand and exert pressure on the pipe walls.
Water molecules expand as they freeze, creating a buildup of pressure within the pipe. Pipes are designed to withstand a certain amount of pressure, but when it exceeds their capacity, they can rupture or burst. Furthermore, pipes made of materials like metal or plastic can become brittle in extremely cold temperatures. The cold causes the material to contract, reducing its flexibility and making it more susceptible to cracks and breaks. This can weaken the structural integrity of the pipe, making it more likely to rupture when subjected to the internal pressure from the frozen water. Preventing pipe bursts during cold winters involves insulating pipes, maintaining a constant flow of water, and keeping indoor spaces adequately heated to mitigate the freezing and expansion of water within the pipes.
Additionally, stagnant water in pipes is more prone to freezing than flowing water. Pipes that aren't used frequently, like those in less-used areas of a building, may freeze more easily during extended cold periods.
