Answer:
It is significant that so much carbon dioxide stays in the atmosphere because, CO2 is the most important gas for controlling Earth's temperature. //Plants breathe in CO2 to give us oxygen.
Answer:
Industry vs. Inferiority Stage
Explanation:
Erik Erikson proposed "8 Psychosocial Stages" that people go through from <em>infancy to adulthood. </em>
Among the stages, Amanda's situation shows that she belongs to the stage of "Industry vs. inferiority." This commonly occurs in children between the ages <u>5 and 12</u>. Here,<em> Amanda knows the importance of going to school and studying.</em> She also knows the value of her teacher in her life. In order to become accepted in the society, <em>Amanda tries her best to be successful in her academic tasks. </em>In this way, she is trying to win the approval of her group of friends or classmates in school. Her good grades reinforced her to study harder.
So, this explains the answer.
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
