Ecosystem is the unit where an organisms interact with each other and with their environment. If abiotic factor were removed, then biotic components would also get died.
Hope this helps!

I thinck it would be 48.0
Answer:
75%
Explanation:
We'll begin by calculating the final volume of the gas. This can be obtained as follow:
Initial volume (V₁) = V
Initial temperature (T₁) = T
Initial pressure (P₁) = P
Final pressure (P₂) = 2P
Final temperature (T₂) = ½T
Final volume (V₂) =?
P₁V₁/T₁ = P₂V₂/T₂
PV/T = 2P × V₂ / ½T
Cross multiply
T × 2P × V₂ = PV × ½T
T × 2P × V₂ = PV × ½T
Divide both side by T × 2P
V₂ = (PV × ½T) / T × 2P
V₂ = ¼V
Next, we shall determine the absolute change in the volume of the gas. This can be obtained as follow:
Initial volume (V₁) = V
Final volume (V₂) = ¼V
Absolute change in volume |ΔV| =?
|ΔV| = |V₂ – V₁|
|ΔV| = |¼V – V|
|ΔV| = |0.25V – V|
|ΔV| = 0.75V
Finally, we shall determine percentage change in the volume of the gas. This can be obtained as follow:
Initial volume (V₁) = V
Absolute change in volume |ΔV| = 0.75V
Percentage change =?
Percentage change = |ΔV| / V × 100
Percentage change = 0.75V / V × 100
Percentage change = 0.75 × 100
Percentage change = 75%
Thus, the percentage change in the volume of the gas is 75%
i honestly don't even know but yahoo answers says :
Impulse causes momentum to change, which means:
Impulse = change in momentum, or in equation form:
F∆t = (mv)2 – (mv)1
so p (impulse)= mass times velocity so the mass is 2,000kg and the velocity is 12,000N/5s.
speed is basically velocity so you have to calculate how many newtons per one second, so 12,000/5s-- just divide the numerator and denominator by 5. Also, velocity and speed are measured in N/s.
Answer:
0.256 J.
Explanation:
The formula for the energy stored in a capacitor is given as
E = 1/2CV².................... Equation 1
Where E = Energy stored in the capacitor, C = Capacitance of the capacitor, V = Voltage.
Make C the subject of the equation
C = 2E/V².................. Equation 2
Given: E = 64 mJ = 0.064 J, V = 1.5 V.
Substitute into equation 2
C = 2(0.064)/(1.5²)
C = 0.128/2.25
C = 0.0569 F.
If the capacitor where fully charged by 3.00 V.
E = 1/2CV²
Given: C = 0.0569 F, V = 3.0 V
Substitute into the equation above,
E = 1/2(0.0569)(3²)
E = 0.256 J.
