In a stronger gravitational field a given mass will have a larger weight.
Iron is a magnetic metal, and it is essential to the Earth's magnetic field!
Essentially it "records" (stores the information, maintains) the direction and orientation of the magnetic field.
Among others, the magnetic field protects the Earth from dangerous cosmic rays.
Answer:0.69
Explanation:
Coefficient of kinetic friction=f/R=61.8/90=0.69
Answer:
When inertia increases, it's because the mass increased, which increases the normal force, which ultimately increases friction.
The basic unit of energy is a joule. Kill calories measure the energy available in food.
