Given that,
Mass of each washer = 4.9 g
We need to calculate the mass of two washers in kg
Using conversion of unit
Mass of each washer 
So, Mass of two washers is

Put the value of m


If 4 washer are attached to the spring
We need to calculate the applied force on the car
Using formula of force

Put the value into the formula


Hence, (i), The mass of two washers is 0.0098 kg.
(ii). The applied force on the car is 0.192 N.
Answer:
Geosphere
Explanation:
The Geosphere is the solid Earth,composed principally of rock (by which we mean any naturally formed, nonliving, firm coherent aggregate mass of solid matter that constitutes part of a planet).
The geosphere is defined to be that component of the Earth system involving the inside of the Earth, rocks and materials, minerals, land forms and the mechanisms that shape the surface of the Earth. Contrary to Christopher Columbus, the Earth is not in itself a perfect sphere.
