Answer:

A system that is programmed for a particular job function is called an embedded system. A a washing machine system is programmed to wash only clothes, and when it sets to a timer, once its done washing its will end the job.

Explanation:

A system that is pre-programmed for a particular function or job is is called an embedded system.

Let us take washing machine system an example, it is an embedded system programmed for washing only, this is so, because washing machine is only used for washing the clothes and not meant for other things or particular application.

when the machine is pre-programmed, if you set a timer for 10 minutes in the washing machine to wash the clothes , after about 10 minutes has elapsed, the machine will stop washing automatically as a result of the micro-controller inside the machine.

Therefore we say the washing machine is programmed for washing of clothes.

A cube measures 3 cm on each side and has a mass of 25 g. What is its density.

Snowcat [4.5K]

Answer:

The density is: $0.926 \,\frac{g}{cm^3}$

Explanation:

Recall that density is defined as the quotient of the object's mass divided by volume. So, we calculate the volume of the 3 cm side cube:

$Vol = (3 \,cm)^3 = 27 \,\,cm^3$

then the density becomes:

$density=\frac{mass}{Vol} =\frac{25}{27} \,\frac{g}{cm^3} \approx 0.926 \,\frac{g}{cm^3}$

Ear "popping" is an unpleasant phenomenon sometimes experienced when a change in pressure occurs, for example,in an airplane. If

marshall27 [118]

Answer:

H = 0.00058m = 0.58mm of Mercury

h = 160m for popping at 8000m

Explanation:

Air density decreases with altitude (increasing height).

At sea level air density = 1.22kg/m^3

while at 3000m above it is approximately 0.8 kg/m^3

ASSUMPTION:

we neglect the change in density across 100m vertically

density of mercury = 13600kg/m ^3

we equate the pressure for mercury and air

AIR(pgh) = Mercury(pgh)

0.8 * g * 100 = 13600 * g * H

H = 0.00058m = 0.58mm of Mercury

At even farther heights, the air density further drops

at 8000m above it is 0.52kg/ m^3 (source:https://www.engineeringtoolbox.com/standard-atmosphere-d_604.html)

***for the ear to pop again, it has to experience same change in pressure as of at 3000m

Change in P for AIR at 3000m = Change in P for AIR at 8000m

ASSUMPTION : gravitational acceleration does not change with altitude

pgh = pgh

0.8 * g * 100 = .5 * g *h

h = 160m

Density: Two blocks, A and B, are put in a tank of water. Block A has a density of 1.21 g/cm³. Block B has a density of 1.37 g/c

stira [4]

Answer:

Block A

Explanation:

Block A will float higher in the water compared to the second Block.

The density of water is 1g/cm³.

According to the principle of floatation "an object that floats in a liquid will displace equal amount of fluid to the weight of the object".

A body will become more submerged in water if it has more density because density is the mass per volume of body.

An object with a higher density than another will sink in the liquid of the one with lesser density.

Object A has lesser density and will float higher up and displace very little water.
Object B has higher density and will be more submerged.
