Remember: Density = Mass Volume
Volume = Length x Width x Height (mL is also a measure of volume)
a Density of a wood cube with 3 cm per side that has a mass of 81 grams
b. Density of a lead cube with 5 cm per side that has a mass of 400 grams
a Density of Liquid A that has a volume of 100 mL and a mass of 200 grams
Density of a
Density of b
Density of c

A. 3g/cm³

B. 3.2g/cm³

C. 2g/cm³

Explanation:

A. Density = mass ÷ volume

Volume = length × width × height

Where;

Mass = 81grams, length = 3cm

Volume= 3cm × 3cm × 3cm = 27cm³

Density = 81/27

Density = 3g/cm³

B) Volume = length × width × height

Where;

Mass = 400grams, length = 5cm

Volume= 5cm × 5cm × 5cm = 125cm³

Density = 400/125

Density = 3.2g/cm³

C) Volume = 100mL

Where;

Mass = 200grams

Density = 200/100

Density = 2g/cm³

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

explanation:

you know that this symptom is misleading and quite often is related to: heart attack

a heart attack is a condition that occurs when the blood flow that transports oxygen to the heart muscle is damaged or cut off completely. the coronary arteries that supply the heart muscle with blood flow can be blocked by the accumulation of plaque. also, when the plaque within the heart artery breaks, it creates blood clot that can also hinder the blood flow. men that are over 45years of age and women that are over 55years of age are at risk of having a heart attack. the symptoms of a heart attack include chest discomfort, chest pain, coughing, and shortness of breath.
