Answer:

Because liquid solutions cannot penetrate the sheet, while gases can penetrate.

Explanation:

The paper is called acid when the internal bonding adding specific chemicals to the fibrous suspension in order to control the penetration of liquids in the sheet is carried out in an acid medium (pH = 4.0 to 5.0) with the addition of glue to the pitch-based, aluminum sulfate and, generally, kaolin as a mineral filler, just to name the main additives. Liquid solutions have difficulties in penetrating the leaves, for this reason, these solutions are not the best option to treat acid paper and it is preferable to use gases.

Objects that are denser than water will sink in water. Question 1 options: True False
den301095 [7]
<h3>Answer: True</h3>

For example, a very dense metal will sink to the bottom while something like wood will float on the surface. The wood is less dense compared to the water, which is why it floats. Density is the measure of how much stuff you can pack in a certain volume. The higher the density, the more stuff per volume. Think of it like packing a suitcase. If there's barely anything in there, then we can say its density is low. The more stuff crammed in the suitcase will increase the density (and therefore the weight), while keeping the volume the same.

Answer:

3kg sledgehammer swung at 1.5 m/s

Explanation:

Small Sledgehammer:

Mass:3.0

Velocity:1.5

MASS×VELOCITY=MOMENTUM

3.0×1.5= 4.5 (momentum)

Large Sledgehammer:

Mass:4.0

Velocity:0.9

4.0×0.9=3.6 (momentum)

higher momentum is the smaller Sledgehammer.

Packages having a mass of 6 kgkg slide down a smooth chute and land horizontally with a speed of 3 m/sm/s on the surface of a co
nalin [4]

Answer:

t = 1.02 s

Explanation:

The computation of the time required is shown below:

The package speed for belt is

= 3 -  1

= 2 m/s

Moreover, the decelerative force would be acted on the block i.e u.m.g

So, the decelerative produced

= 0.2 × 9.81

= 1.962 m/s^2

And, final velocity = 0

v = u - at

here

V = 0 = final velocity

 u = 2 m/s

so,

0 = 2 - 1.962 × t

t = 1.02 s
