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:
166.67%
Explanation:
The computation of the percentage increase in grain production for the period 1950-1955 is shown below:
= (Year 1995 grain production - Year 1950 grain production) ÷ ( Year 1950 grain production)
= (1,600 million tons - 600 million tons) ÷ (600 million tons)
= 1,000 million tons ÷ 600 million tons
= 166.67%
Hence the increase in percentage is 166.67%
Answer:
B. Undernutrition
Explanation:
The reason why A. malnutrition is not correct is that malnutrition arises from lacking a few or one specific nutrient in your body.
Undernutrition arises because of inadequate intake of dietary energy regardless of specific nutrients.
While we use malnutrition in day to day use as an umbrella term for inadequate diets that is not the real meaning of that word.
Non renewable resources are formed over very long periods of time.
The answer is in the name, “non renewable”.
