Answer:
1,362.2 N
Explanation:
1. Find what you have and what you need.
Weight = 175lb 1lb= 4.448N Gravity of Alderon to Earth 1.75:1 Weight on Alderon in N?
2. Convert the units from lb to N and then muliply by 1.23.
= 1,362.2 N
Maybe it not meant to be or it complicated
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:
C.
What do genealogists have to look forward to in the future?
Explanation:
After reading the article, the reader learns about the history of genealogy dating to as far back as ancient Rome. The various ways by which ancient people kept and traced records were highlighted in the text. The writer records this chronology down to our present generation were the World Wide Web has made the keeping of records even simpler.
At this point, and after reading the last paragraph where the writer assumes that soon tracing genealogies will be as simple as pushing a button, the reader might now wonder the new inventions that would be possible in the future and that would make the tracing of genealogies even easier.
If there was no moon, there would be no waves, no tides, no convection, no weather, and so the biosphere would be completely different
