Weight= Mass x Gravity. Gravity on Earth is 9.81. Therefore if you multiply 42 by 9.8, you will get 411.6 which is her weight on Earth.
Answer: Is permanently deformed.
Explanation (see the diagram shown below).
For most structural materials:
(a) The deformation in the elastic zone is recoverable, and the material returns
to its original shape when the load (or stress) is removed.
(b) A permanent set (non-recoverable deformation) occurs when the material
is sressed beyond the elastic zone, that is, in the plastic zone.
Answer:d
Explanation:
All the given situations are possible because
(a)When particles are oppositely charged then they attract each other
(b)One is Positively charged and other is uncharged: Charged particle will induce charges of opposite nature to attract the other particle
(c)Negatively charged particles will induce the positive charge in the uncharged particle to attract the initially uncharged particle.
Galileo Galilei was the first to systematically study force and motion.
He began doing so by conducting experiments to search for the cause of motion.

Answer:
Explanation:
"Rotation" refers to an object's spinning motion about its own axis. "Revolution" refers the object's orbital motion around another object. For example, Earth rotates on its own axis, producing the 24-hour day. Earth revolves about the Sun, producing the 365-day year.
