A mountain lion is a consumer , a worm is a decomposer !
Hope this helps! :)
I believe it is a conductor I am learning this myself so I may be wrong
Answer: Frequency distribution helps to understand data. some complex data needs to be converted into intervals to see its frequency of occurrence. it helps to find the mean median and mode of the data. It helps in the analysis of data and its practical implementation.

Answer:
433903.8 N
Explanation:
From work energy theorem, the total work done is equivalent to change in kinetic energy. Kinetic energy is depedant on speed and since pile drive finally comes to rest, then final velocity is zero. Also, its initial velocity is not given. Therefore, the sum of work due to gravity and beam equals to zero. Work due to gravity is product of mass of pile driver, acceleration due to gravity and height while work due to beam is a product of force and distance. Substituting the given values then
2300*9.81*3+(F*0.156)=0
F=-433903.84615384615384615384615384615384615 N
Approximately, the magnitude of force is 433903.8 N and it acts upwards
Answer:
37.7 Ω
Explanation:
The resistance in each lamp is:
P = IV = V²/R
R = V²/P
R₁ = (110 V)² / (150 W)
R₁ = 80.67 Ω
R₂ = (110 V)² / (200 W)
R₂ = 60.5 Ω
Their combined resistance in parallel is:
1/R = 1/R₁ + 1/R₂
1/R = 1/(80.67 Ω) + 1/(60.5 Ω)
R = 34.57 Ω
So the current that goes through them is:
V = IR
I = V/R
I = (110 V) / (34.57 Ω)
I = 3.182 A
We need the same current in the new circuit.
V = IR
230 V = (3.182 A) (R₃ + 34.57 Ω)
R₃ = 37.7 Ω
We can check our answer by finding the voltage drop across this resistor:
V = I R₃
V = (3.182 A) (37.7 Ω)
V = 120 V
230 V − 120 V = 110 V, the correct voltage for the lamps.
