Answer:
Gravity explains this.
Explanation:
Weights and mass are different terms .
Weight is defined as the force exerting on the surface due to the mass and gravity of acceleration.

Here mass is related to the density of the body. So as the density would be same mass woulnt vary.
Whereas the Gravity changes due to the property of the planet.
Gravity is different for different planets and hence moon and earth have two different values.
So the mass i.e density remains same on both planets but the g value always changes hence weight is different.
Answer:
B. 26.00 g Fe
Atomic mass of Fe (Iron) is 55.845g
Answer:
An object with a high mass close to the Earth could be sent out into a collision course with the asteroid, knocking it off course. When the asteroid is still far from the Earth, a means of deflecting the asteroid is to directly alter its momentum by colliding a spacecraft with the asteroid.
Hope it helps!!
