Answer:
I think that the answer is E
Explanation:
Answer:
0J
Explanation:
Mass of the lump M1 = 1.0 kg, initial velocity of the lump U1 = 2m/s to the right,
mass of the metal sphere M2 = 0.5kg, initial velocity of the metal sphere M2 = -4m/s to the left. using conservation law of momentum;
M1U1 + M2U2 = V (M1 + M2)
(1.0 × 2) + (0.5 × -4) = V (1 + 0.5)
2 -2 = V (1.5)
0 = V (1.5)
divide both side by 1.5
0/1.5 = V 1.5/1.5
V = 0
since final velocity after sticking together of the two masses equals zero then their combined kinetic energy will also equal to zero
1/2 V(M1 +M2)
1/2 ×0 × 1.5 = 0J
Answer:
square metres of plant materials required to support the fox = 3650 m²
Explanation:
From the given information:
the daily caloric requirement of the fox = 800
In a year, we have = 800 kcal × 365 /year = 292,000 kcal/year
Also, only 10% of the energy at a particular trophic level can be passed onto the next.
the net productivity of the plant material = 8000 kcal/m²/yr
So, using 10% of energy at a particular level, the fox only need 80 kcal/m²/yr
The objective is to determine in square meters, how many materials are required to support the fox.
square metres of plant materials required to support the fox = 
= 3650 m²
