A third-class lever.

that an entire species going extinct is bad for the whole ecosystem

For example, it should show the result from 1 to 142. But actually, only 1-83 and 142 has been shown, lacking of 84-141.

What's the cause of that! How to improve? Thank you so much!

According to a calculator I used The New Temperature is -178.2

This is using PV = NRT and with only 1 mole of gas calculate the volume first with the stuff you gave and then calculate the new value using that volume

Just like magic you get -178.2 Celsius

Ps i did use 2870 and 8440 which are the above pressures but not in standard form.

1. gear teeth profile
2. scroll compressor

It is to open the power-switch at zero current to minimize the looses during switching.

External schemas allows data access to be customized (and authorized)

at the level of individual users or groups of users. Conceptual (logical) schemas describes

all the data that is actually stored in the database. While there are several

views for a given database, there is exactly one conceptual schema to all users. Internal

(physical) schemas summarize how the relations described in the conceptual schema

are actually stored on disk (or other physical media).

External schemas provide logical data independence, while conceptual schemas offer

physical data independence.

How the weight of the body is balanced in a horizontal circle?

mass [kg] = volume [m^3] * density [kg / m^3]

From Newton's 2nd law of motion, weight [N] = mass [kg] * 9.8 [m/s^2] = volume [m^3] * density [kg / m^3] * 9.8 [m/s^2].

Rearranging, we get volume = weight / (density * 9.8) [m^3]

Find the weight in [N], then you will know the volume in [m^3].

No, planes don't have catalytic converters.

importance of solid mensuration in marine transportation?

If you mean a 'spirit level' then when the line is in the center of the bubble then the object being measured is horizontal to the ground.

The Nation Institute of Standards and Technology web site has the figures

Note there are three coefficients - the Antoine equation gives a reasonable fit to vapour pressure.

Engineering is the discipline, art, skill and profession of acquiring and applying scientific, mathematical, economic, social, and practical knowledge, in order to design and build structures, machines, devices, systems, materials and processes that safely realize improvements to the lives of people.

We must assume that Susie's weight was recorded on earth.

Since she weighs 300N on earth, her mass is 30.61 kilograms.

If her weight had been 300N somewhere else, like on Mars or the moon,

it would mean that her mass is some different figure.

The sound when approaching you is being bunched up by the speed it is going in air. As it comes nearer the frequency increases, hits actual pitch, then it decreases as it goes away from you. The sound wave being spread out by the motion increasing separation between the listener and the source. Also changing the time it takes to get to the listener.

very very important bcos ur all fools

I understand that the term "work" is used mainly for the transfer of mechanical energy. So, perhaps, the more appropriate term here would be "energy".

You would have to find the material's thermal inertia, in this case, its volumetric heat capacity - look it up, usually, or calculate it on the basis of its specific heat, which you would look up instead. Once you have that, just multiply the volume x the desired difference in temperature.

The discovery of fire was probably first, although nobody really knows for sure which technological development happened first.
