how will knowing the density of a substance help you determine whether an object made from that material will float in water
trapecia [35]
The density of water is about 1kg/m³, therefore is the substance has a density of less than 1kg/m³ then it will most likely float however if it is more than 1kg/m³ then it will most likely sink.

lana [24]

Answer:

active transport

Explanation:

Active transport -

It refers to the movement of the molecules from a region of lower concentration towards a region of higher concentration via a membrane , is referred to as active transport.

The process of active transport need to have some cellular energy .

Hence,

The concentration of potassium is maintained in the red blood cells via the process of active transport.

A rectangular tank is filled with water to a depth = h, the tank width and length are w and 1 respectively. Calculate the ratio
AnnZ [28]

Answer:

\frac{\textup{2}}{h}

Explanation:

Given:

Depth = h

Width = w

Length  = 1

Now,

Let ρ be the density of water

Thus,

Pressure force at the bottom will be

= Pressure × Area

= ρgh × (w × 1)

also,

Pressure force at the sides will be = \frac{\textup{1}}{\textup{2}}\times ρgh × (h × w)

Therefore,

The ratio of the pressure force at the bottom to the pressure force on the side of the tank will be

= \frac{\rho gh\times w\times1}{\frac{1}{2}\times\rho gh\times(h\timesw)}

= \frac{\textup{2}}{h}
