How might an ecologist Measure population density of pine trees in an actual forest?

Physics
1 answer:
ruslelena [56]4 years ago

<span>Ans : The best way to estimate the population density of pine trees in an actual forest is to count the number of trees in a small area and than multiply to find the number in a large area. To get the most accurate estimate, your sample area should be typical of the larger area. Suppose you count 10 pine tree in 100 sq meters of the forest. If the entire forest were 100 times the size, you would multiply your count by 100 to estimate the total population density, or 1000 (10X100) pine trees.</span>

TRUE OR FALSE : Boyle’s law states that, as the pressure of a gas increases, the volume decreases.
White raven [17]

True, but only if the temperature of the gas doesn't change ...
which is pretty hard to manage when you're compressing it.

I think Boyle's law actually says something like

       (pressure) x (volume) / (temperature)  =  constant.

So you can see that if you want to say anything about two of the
quantities, you always have to stipulate that the statement is true
as long as the third one doesn't change.

How long does a car (1000 kg) have a speed of 30 m/s from a rest if the engine power is 10kw
Lemur [1.5K]

Answer: 90.1 s

Explanation:

Use equation for power:

P=F*V

Use eqation for force:

F=ma

F---force

V---velocity

Vr=om/s

V=30m/s

m=1000kg

P=10000W

---------------------------

P=FV

F=P/V

F=10000W/30m/s

F=333.33N

Use equation for force to find accelartaion.

F=ma

a=F/m

a=333.33N/1000kg

a=0.333 m/s²

Use equation for accelaration to find out time:

a=(V-Vs)/t

t=(V-Vs)/a

t=(30m/s)/(0.333m/s²)

t=90.09 s≈90.1 s

What is the wavelength of an fm radio signal that has a frequency of 91.7 mhz?
Digiron [165]

Answer:

The wavelength of the radio wave will be 3.271 m

Explanation:

We have given frequency of the radio signal f=91.7MhZ=91.7\times 10^6Hz

Speed of the light c=3\times 10^8m/sec

We have to find the wavelength of the radio signal

We know that wavelength is given by \lambda =\frac{c}{f}=\frac{3\times 10^8}{91.7\times 10^6}=3.271m

So the wavelength of the radio wave will be 3.271 m
