True. The world population in 1965 was 3.324 billion . In 2000 the world population was 6.115 billion. The difference is 2.791.
Answer: A. Gamma Ray
Explanation:
X-ray scans can diagnose possibly life-threatening conditions such as blocked blood vessels, bone cancer, and infections. However, x-rays produce ionizing radiation—a form of radiation that has the potential to harm living tissue. However, the risk of developing cancer from radiation exposure is generally small.

The pH of pure water has been best described as neutral pH with equal hydronium and hydroxide ions. Thus, option A is correct.
pH has been described as the measurement of hydrogen ions in a solution. The pH has been measured on a scale of 1-14. pH 7 has been the neutral pH.
The higher hydronium ion concentration tends to move the pH from 7 towards 1. The higher hydroxide ion concentration tends to move the pH above 7.
The neutral pH has been neither acidic nor basic with the equal constituents of hydronium and hydroxide ion in the solution.
Thus, the pH of pure water has been 7. It has neutral pH with equal hydronium and hydroxide ions. Thus, option A is correct.

Answer:
D is the answer to this problem
Answer:
d. inversely proportional to the volume of its container.
Explanation:
Boyle's law states that at constant temperature and number of moles, the pressure of the gas is inversely proportional to the volume of the gas.
Thus, P ∝ T
P is the pressure
T is the temperature
For two gases at same temperature, the law can be written as:-
<u>Thus, according to the question, the answer is:- d. inversely proportional to the volume of its container.</u>
