Answer:
0.466 (3 sig. fig.)
Explanation:
Frictional force acting on the box = 5.00×10^2xsin25
Normal force acting on the box = 5.00×10^2xcos25
coefficient of friction = 0.466 (3 sig. fig.)
Answer:
F(friction) = μ M g definition of frictional force
μ = F / (M g) = 11 N / 50 N = .22

Answer:
negative ion
Explanation:
An atom that has fewer neutrons than protons and more electrons than protons is a negative ion.
The positively charged particles in an atom are the protons
The negatively charged particles in an atom are the electrons.
The charge an atom carries depends on the balance between the number of protons and electrons in an atom.
- When the number of protons is more than the number of electrons, the atom is positively charged.
- When the number of electrons is more than the number of protons, the atom is negatively charged.
Making models
is a skill that involves creating a representation of complex objects or
processes. Through the years, people have been creating models in order to
make a clearer visualization and give reality to a certain object. Some
example of model making are toys like plastic cars as a model
representation of a real car, a plastic plane, model representation of a
real plane and a doll, a model representation of us, human. One of the
most famous model representation as of today is the film or movie making.
This represents the lives of the people and show stories about how people
face every challenge in life.
