What is the difference between acceleration and linear acceleration?

Akimi4 [234]

Linear acceleration is a type of acceleration of a body along a straight path or line.

Acceleration is defined as the rate of change of velocity with time.

Acceleration = $\frac{Change in velocity}{time}$

There are different types of acceleration .

linear acceleration is used to describe the rate of change of velocity of a body along a straight path with time.
centripetal acceleration is the rate of change of velocity of a body traveling along a circular path with time. It is directed towards the center.

If the density of a diamond is 3.5 /cm^ 3 what would be the mass of a diamond whose volume is 0.5 cm ^ 3 ?

Elan Coil [88]

Answer:

1.75g

Explanation:

Given parameters:

Density = 3.5g/cm³

Volume = 0.5cm³

Unknown:

Mass of the diamond = ?

Solution:

Density is the mass per unit volume of a substance

Density = $\frac{mass}{volume}$

So;

Mass = 3.5 x 0.5 = 1.75g
