A physical property is any property of a physical system that is measurable. [1] The changes in the physical properties of a system can be used to describe its changes between momentary states. A quantifiable physical property is called physical quantity. Measurable physical quantities are often referred to as observables.
The 2020 Karachi floods (Urdu: سيلاب کراچی ) were the worst flooding Karachi had seen in almost a century, and killed at least 41 people. [1] [2] [3] The floods were caused by record monsoon rains from 24 to 27 August, [4] which were inadequately drained by poorly maintained drainage systems in the city.
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge.Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations.
[2] [3] [4] A scientist who specializes in the field of physics is called a physicist. Physics is one of the oldest academic disciplines . [ 5 ] Over much of the past two millennia, physics, chemistry , biology , and certain branches of mathematics were a part of natural philosophy , but during the Scientific Revolution in the 17th century ...
The National Disaster Management Authority (Urdu: مقتدرہ قومی آفات انتظامی پاکستان, abbreviated as NDMA), is an autonomous and constitutionally established federal authority mandated to deal with the whole spectrum of disasters and their management in the country.
The Emergency Services Academy, the first training institute of its kind in Pakistan, was established as a center for imparting emergency medical training, fire fighting, structural collapse search and rescue, high-angle and confined space rescue, water rescue, and other emergency management skills.
The agricultural damage reached more than 2.9 billion dollars, and included over 700,000 acres (2,800 km 2) of lost cotton crops, 200,000 acres (810 km 2) of sugar cane and 200,000 acres (810 km 2) of rice, in addition to the loss of over 500,000 tonnes of stocked wheat, 300,000 acres (1,200 km 2) of animal fodder and the stored grain losses.
