The density of the object is the ratio of its mass and volume. From the given dimensions above, we determine the volume through the equation,
V = L x W x H
Substituting,
V = (3 cm)(2 cm)(1 cm) = 6 cm³
From the idea presented above,
d = m/V
Substituting the known values,
d = (30 g)/ (6 cm³) = 5 g/cm³
ANSWER: 5 g/cm³

The most widely accepted scientific explanation of the origin of the universe is D. The big bang theory.
The radio waves have a very low frequency so they will always have a very low energy.
Good luck :)
The acceleration of the car at impact is 15m/s².
<h3>What is Newton's Second Law of Motion?</h3>
Newton's second law provides a precise explanation of the modifications that a force can make to a body's motion. According to this, a body's momentum changes at a rate that is equal to the force acting on it over time in both magnitude and direction. A body's momentum is equal to the sum of its mass and velocity. Similar to velocity, momentum has both a magnitude and a direction, making it a vector quantity.
acceleration - rate of change of velocity with time, both in terms of speed and direction. A point or object going straight forward is accelerated when it accelerates or decelerates.
There are three types of accelerated motions :
- uniform acceleration,
- non-uniform acceleration
- average acceleration.
express all the units in their most basic form.
kg, newton = kg*m/s², acceleration =m/s²
