Difference between impulse and impulsive force

Answers

Answer 1
Answer: Impulse is caused by a force during a specific time that is equal to the body's change of momentum
Impulsive force: the process of minimizing an impact force can be approched
Answer 2
Answer: An impulsive force would be, say, a punch. Something that lasts a short time.An impulse can, I guess, be anything that lasts for a short time. Such as a sound impulse, say when a door slams shut.

The amount of pressure in a gas is measured in pascals. TRUE or FALSE.

Answers

True Pascals Is Used To measure Amount Of Pressure In A Gas
(Any unit of force) divided by (any unit of area) is a unit of pressure.

1 pascal = 1 newton / 1 square meter

So a pascal is an acceptable unit of pressure, and the statement
is true.  It's very popular worldwide for this purpose, but it's by no
means the only one used everywhere.  We also still see measurements
in units of pounds per square inch, Torr, millibars, atmospheres, etc.

A truck accelerates 2 m/s2 when it is empty. If the truck is filled so that it has twice the mass and the same amount of net force is applied, how much will the truck accelerate?8 m/s2
1 m/s2
4 m/s2
2 m/s2

Answers

Answer :

a = 1 m/s^2

Explanation:

Given information

Net force is a constant

The mass of the truck is m_(o)

Initial acceleration a_(o)= 2 m/s^(2)

The mass of the truck is increased twice as much

F_(net)= m_(o) a_(o) = ma

F_(net)= m_(o) a_(o) = 2m_(o)a

a=\frac{a_(o) } {2}

a = 2/2

a = 1 m/s^(2)

During a very cold winter, water pipes sometimes burst. Why?

Answers

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.

Change the following data into scientific notation.

5 000 000 km

Answers

To find out scientific notation, you want to make sure that number is less than 10. So do 5.000000, you don't rally need the zeros but I just want to make my point. So use 10^x meaning ten the whatever power adds zeros like 5.000000x10^6 meaning it is increasing it by six zeros moving it out of the decimals and letting become 5,000,000. 

Answer:

the answer is B) 5x10^6
