__Dry and Liquid Measurements__
Explanation:
Density is defined as a material per unit volume of the material.
The determination of the density of a liquid with an aerometer is based on the principle of Archimedes' law: "Any object that is immersed in a liquid will experience a lift which is equal to the weight of the liquid being moved".
The aerometer is in the form of a hollow cylinder, so that the aerometer can be immersed in the right position (the scale is immersed in liquid), then the aerometer is filled with Pb grains. The scale on the aerometer shows the density of the liquid, the smaller the density of the liquid, the deeper the aerometer will be. Therefore the aerometer scale shows an increasing number from top to bottom.
Answer:
b) the effects of local evolution or migration on an exosystem
Explanation:
a) false; symbiosis is the relationship between two species with either a mutual benefit to both creatures, one benefiting and the other remaining neutral, or one being negatively affected while the other benefits. There is no relationship between the two groups of blackcaps to a is false.
b) true; the effects of local evolution or migration on an ecosystem. Local evolution has not occured yet but migration has. The effect that scientists believe may happen to the ecosystem because of the migration is the creation of a new species, which would definitely effect an ecosystem
c) false; biotic factors are the living parts of an environment, such as plants, animals, and insects. The difference in the two groups of blackcaps isn't what biotic factors they use but when their mating season is. Biotic factors have no effect whatsover.
d) false; there are no given alterations in the ecosystem. Migration patterns do not just change because of something as small as a shift in bug population. Migration habits are largely genetic, such as is the case of monarch butterflys migrating from north to south and back across the continent. If a group of blackcaps are migrating somewhere different, it has been ocurring for a while, so it isn't fault of the ecosystem that suddenly made blackcaps switch migration course.
2 equally sloped side= shed
Gabled= one sided slope
Gambrel= curved
Answer:
1.5x10^10 KWh
Explanation:
Data obtained from the question include:
Power (P) = 3GW
We need to convert 3 gigawatts (GW) to Kilowatts (KW) in order to obtain the desired result. This is illustrated below:
1 GW = 1x10^6 KW
Therefore, 3 GW = 3x10^6 KW
Time (t) = 5000 hrs/yr
Energy (E) =?
Power is simply the amount of energy transferred per unit time. It can be expressed mathematically as:
Power (P) = Energy (E) / Time (t)
P = E/t
Applying the above formula, we can calculate the energy in kWh of electricity that can be produced by the plant in one year. This is illustrated below:
P = E/t
3x10^6 KW = E / 5000 hrs/yr
Cross multiply to express in linear form as shown below:
E = 3x10^6 KW x 5000 hrs/yr
E = 1.5x10^10 KWh
Therefore, 1.5x10^10 KWh of electricity can be produced by the plant in one year.
