One nanometer is equal to how many centimeters?

1 cm = 10,000,000 nm

Explanation:

Since 1 meter = 100 centimeter

and     1 meter = 1,000,000,000 nanometer

so,       1 cm =  10,000,000 nm

Here we can simplify a formula to convert cm to nm as

nanometers = 10,000,000 multiplies centimeters.

Example: convert 8 cm into nms.

                 so nm = 10,000,000 multiplies 8

                               80,000,000 nms

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

that the claims meet official rules.

don't misinterpret the claims
