In order to help the student expand his/her knowledge I will help answer the question. This in hope that the student will get a piece of knowledge that will help him/her through his/her homework or future tests.

All of the mentioned factors determine the amount of electric current in a circuit exept for the ammeter. The ammeter is a measuring tool which does not affect the lfow of electric current in a circuit. The answer is  

Switch
Voltage
Resistance   <span> 

I hope it helps, Regards.</span>     <span> </span>

So, voltage (U) and resistance (R) are linked with current (I) by the equation I = \frac{U}{R}, that THE basic law of electricity. Onther two things mentioned are a component (switch), a mechanical part, and an instrument (ammeter), that is used to measure the current, but does not change or control it. The answer is Voltage and Resistance.

Discuss two components that are essential to the functioning of the ecosystem.
Gre4nikov [31]

Answer:

The two components are biotic and abiotic components

Explanation:

The two components essential for the functioning of the ecosystem are:

Biotic Components:

These are the organic components like plants, pathogens, animals, human beings and other living components in the ecosystem that affects other living organisms, influences them and helps in shaping the ecosystem.

they require desired amount of nutrition and energy and energy for proper everyday functioning.

They are further classified as Producers, decomposers and consumers out of which producers prepare their own food by photosynthesis where consumers fulfills their requirement from producers and decomposers depend s on both producers and consumers for chemical breakdown into simpler and reusable forms.

Abiotic Components:

These are the inorganic components of the ecosystem like humidity, temperature, etc.

These are the non living components of the ecosystem which includes physical and chemical constituents of the environment which influences the biotic components and the ecosystem's functioning.

The abiotic components influences certain behaviors in living organisms like reproduction, growth, etc.

These components are synthesized by the process of photosynthesis by utilizing sunlight to convert these into organic compounds by primary producers which are further are the consumption of secondary producers thus increasing the organic content.

You attach a meter stick to an oak tree, such that the top of the meter stick is 1.87 meters above the ground. Later, an acorn f
Verdich [7]

To solve this problem we will apply the concepts related to the kinematic equations of linear motion. We will calculate the initial velocity of the object, and from it, we will calculate the final position. With the considerations made in the statement we will obtain the total height. Initial velocity of the acorn,

u = 0m/s

Also, it is given that the acorn takes 0.201s to pass the length of the meter stick.

s = ut+\frac{1}{2} at^2

Replacing,

1 = u(0.141)+ \frac{1}{2} (9.8)(0.141)^2

u =6.4013m/s

The height of the acorn above the meter stick can be calculated as,

v^2 = u^2 +2gh

h = \frac{v^2-u^2}{2g}

h = \frac{6.4013^2-0^2}{2(9.8)}

h = 2.0906m

Also the top of the meter stick is 1.87m above the ground hence the height of the acorn above the ground is

h = 2.0906+1.87

h = 3.9606m
