کشش ثقل اشیاء کے درمیان درمیانے درجے کا ______ ہے۔
Answer: Independent
Explanation The gravitational force between two objects is independent of the medium between them. Gravity acts through a vacuum just as it does through a medium like air, water, or solid objects. The presence or absence of a medium does not affect the gravitational force between the objects.
Answer: 1/2 Joule
Explanation The kinetic energy (K.E) of an object is calculated as: K.E = (1/2) x mass x velocity^2 = (1/2) x 1 kg x (1 m/s)^2 = 0.5 Joule = 1/2 Joule So, the kinetic energy of the body is 1/2 Joule or 0.5 Joule.
جو ایٹم اپنے بیرونی خول سے دو الیکٹران کھو کر آئن بناتا ہے اسے _____ کہتے ہیں؟
Answer: Magnesium
Explanation Magnesium (Mg) is an alkaline earth metal that loses two electrons from its outer shell to form a divalent cation (Mg²⁺). This means that it typically loses two electrons to form compounds, resulting in a valency of +2.

Answer: Ratio
Explanation A ratio is a comparison of two values or quantities , often expressed as a fraction or a decimal. It shows the relative size or magnitude of one value compared to another. For example : 2:3 or 2/3 is a ratio comparing the value 2 to the value 3.
ایکسلریشن کی ایس آئی یونٹ کیا ہے؟
Answer: m/s²
Explanation The SI unit of acceleration is meters/second^2 ( m/s^2 or ms^-2) Acceleration (a) is defined as the rate of change of velocity. Velocity is a vector quantity, and therefore acceleration is also a vector quantity.
تمام منتقلی عناصر _____ ہیں؟
Answer: Metals
Explanation Transition elements , also known as transition metals , are a group of elements in the d-block of the periodic table. They are characterized by their ability to form ions with different charges. They are often found in the middle of the periodic table.
پانچ بادشاہی نظام میں وائرس ______ میں رکھا گیا ہے؟
Answer: None of these
Explanation In the five-kingdom system , viruses are not placed in any of the five kingdoms: Monera (bacteria) Protista (eukaryotic organisms) Plantae (plants) Animalia (animals) Fungi (fungi) Viruses are considered non-living entities. So, in the five-kingdom system , viruses are not classified in any of the five kingdoms.
