Explanation:
there are many things. I am not sure what your teacher told you.
one of the first strange observations leading to this conclusion was the "loop-di-loop" in the track of Mars. because of the different orbits of Earth and Mars, sometimes one (particularly Earth as the faster one) swings around the sun in relation to the other, and with that first moves away and suddenly moves closer again, making the track of Mars appear on Earth as if it would make a loop in the sky.
Answer:
D 500 N
Explanation:
As the velocity is constant the scale reads the same whether at rest, or at a fixed velocity. The only thing that would make the scale read differently would be a vertical acceleration.
Answer:
Newtons third law of motion
Explanation:
For each action, there is an equal and opposite reaction.
Answer:
sir Isaac Newton is referred as the father of modern physics
Hydrogen = mass = 1 u = 1 g/mol
Lead = mass = 207,2 u = 207,2 g/mol
1 kg = 1000 g
1000g / 1g/mol = 1000 atoms H
1000g / 207,2g/mol = 4,82 atoms Pb
Soon, we have more hydrogen atoms
