<u>Answer:</u>
A) Mass of dinosaur = 77,000 kg
Weight of dinosaur = 755370 N
B) Mass of dinosaur = 77,000 kg
Weight of dinosaur = 377685 N
<u>Explanation:</u>
A) Mass of dinosaur the brachiosaurus = 77,000 kg
We have weight of body = mg = 77,000*9.81 = 755370 N
B) Mass of a body is constant, it will not get affected by change in acceleration due to gravity value.
So, Mass of dinosaur = 77,000 kg
We have weight of body = mg' = m*g/2 = 77,000*9.81/2 = 377685 N
