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
As different species evolved, it can be seen that those pressures influenced how their cutaneous senses developed through the changes and sensory adaptation. In different climates and situations, one would need to adapt in order to survive. Ex. Someone who works in construction or gardening would develop callouses from the pressure of the tools they use.
Answer:
3.1 because you round the numbers to the nearest .1 spot if its .5 or above then it goes to the next whole number
