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 : When a raw egg is placed in vinegar then it dissolves the shell of egg and makes it a naked egg.
Explanation : The shell of the egg is made up of calcium carbonate and when placed in vinegar which is mainly made up of acetic acid, dissolves the outer shell covering of calcium carbonate and makes the egg naked. This makes the raw egg bouncy in nature.
The three possible ways we could attempt an interpretation of the finding are listed below.
1. Society as a whole has failed its adolescents by not ensuring that they are brought up in healthy homes.
2. Parents have not created healthy homes for their children. Childbearing comes with a set of responsibilities on those who engage in the activity.
3. It is imperative to ensure that adolescents receive adequate love and understanding in healthy homes so that they may behave healthily.
Thus, since one cannot give what she or he does not have, society must ensure that we have healthy homes for the growth of adolescents and the nurturing of healthy habits.
