Answer:
THE MASS OF THE LIQUID IS 22.5 g
Explanation:
Density = 0.180 g/cm3
Side length = 5 cm
Mass = unknown
To calculate the mass of the liquid, we use the formula:
Mass = density * volume
Volume of a cube or cuboid container = l^3
Volume = 5 ^3 = 125 cm3
So therefore, the mass of the liquid is:
Mass = 0.180 * 125
Mass = 22.5 g
In conclusion, the mass of the liquid in the container is 22.5 g

List three unique examples of situations in your daily life where expansion and contraction occur.
The momentum of a 5-kilogram object moving at 6 meters per second is-
The momentum of an object is 30 kgm/s . This can be calculated by using momentum formula see description below.
What is momentum?It is defined as the product between mass and velocity. Its symbol is p.
It is given by:
p = m * v
What information do we have?
Mass = 5kg
Velocity = 6 m/s
To find:
Momentum=?
On substituting the values:
p = m * v
p =5 kg * 6 m/s
p = 30 kgm/s
Thus, the momentum of an object is 30 kgm/s.

How does Density depend on the type of object being measured ?
Answer:
ways to exaplined
Explanation:
Density is calculated by
dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL. If both water samples are at the same temperature, their densities should be identical, regardless of the samples' volume.
