Answer:
The mass of the feather would be 0.0075 kg.
Explanation:
If the feather were to be on earth, it would have experienced the gravitational pull of the earth downwards. So that from Newton's second law of motion,
F = mg
where f is the force on the object, m is the mass of the object and g is the acceleration due to gravity of the earth.
But, F = 0.075 N, g = 10 m/.
So that,
0.075 = m x 10
m =
= 0.0075 kg
The mass of the feather would be 0.0075 kg.
Explanation:
As the atomic number increases, so does the number of electrons and protons.

Friction can be defined as a type of force that prevents two smooth surfaces from sliding together on each other. Friction is a strong force that oposses motion when two surfaces come in contact with each other.
The different methods/ways to reduce friction include;
- Application of lubricant to surfaces
- Streamlined bodies; this goes a long way in preventing friction between two bodies.
- Decrease in weight; reducing the amount of weight on a substance can also help to reduce friction
- Applying wheels to objects that move/roll on the ground.
