Answer:
0.90291 m/s
0.45055 m/s
Explanation:
= Mass of canon = 2090 kg
= Mass of ball = 16.7 kg
= Velocity of canon
= Velocity of ball = 113 m/s
In this system the momentum is conserved

The velocity of the cannon is 0.90291 m/s
Applying energy conservation

The ball would travel 113.45055-113 = 0.45055 m/s faster
Answer: Step Ladders
In general ladders are with inclined or vertical set of steps or rungs between two upright lengths of metal or wood. Ladders used for climbing up and down.
<u>Step ladders :</u>
It is a self supporting portable ladder, most commonly used in industries. Self-supporting means it does not need any support to lean. So this ladder can be used any where in the rooms. For example middle of the room where support is not available. Also this ladder is non-adjustable flat steps and hinged back.
Answer:
Devni is correct
Explanation:
The relationship between pressure and density of a liquid is directly proportional i.e. the amount of pressure exerted on a liquid is directly proportional to its density and this is because when pressure is exerted the volume is compressed hence there will be a proportional increase in density as well.
hence pressure is as important as density in liquids
