The density of lead is 11.3 g/cm3. what is this value in kilograms per meter cubes?

11300 kgm⁻³

Explanation:

Density is defined as the mass per unit volume. It is an intensive property,

Unit conversion

1 g = 1*10⁻³ kg

1 cm³ = 1*10⁻⁶ m³

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.

this would be about 43%
