12 If pressure is applied to a rock until its volume is
mote1985 [20]

Answer: The correct answer to the question is option 2

If pressure is applied to a rock until it's volume is reduced by one half how the new density compares to it's original density is ; THE NEW DENSITY IS TWICE IT'S ORIGINAL DENSITY.

Explanation: Density is defined as mass divided by volume,density increases with pressure and it's determined by spaces between atoms in the object being measured.

Density is directly proportional to Pressure,so when pressure increases, Density increases and when pressure decreases,density decreases.

Density is indirectly or inversely proportional to temperature. so when pressure and density increases, temperature remains constant.

This is applicable to the scenerio with the rock in the question,as the pressure on the rock is increasing,the density is increasing too.

Natasha_Volkova [10]

Answer:

The correct answer is option b, 0.3m/s

Step by Step solution:

The relation between speed, wavelength and frequency of a wave is given by the following equation:  

Speed = Wavelength x Frequency

Substituting the values in above equation we get –  

= 3  x 0.1  

= 0.3 m/s

What type of blood does the pulmonary artery transport?
Verizon [17]

Answer:

The pulmonary artery carries oxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveolar and becomes oxygenated as part of the process of respiration. In contrast to the pulmonary arteries, the bronchial arteries supply nutrition to the lungs themselves.

Why is it important to avoid planting the same crop in the same field year after year
4vir4ik [10]
Planting the same crop in the same place each year zaps nutrients from the earth and leaves soil weak and unable to support healthy plant growth. Because soil structure and quality is so poor, farmers are forced to use chemical fertilizers to encourage plant growth and fruit production.
