6.0 × 10^26 kg
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The mass of Earth is approximately 6.0 x 10^24 kilograms ( 5.98 x 10^24 kg ).
This is a widely accepted scientific value , based on various measurements and calculations, including:
Gravity measurements Satellite orbits Seismological data Planetary formation models
دو پوائنٹس کے درمیان سب سے کم فاصلہ _____ کہلاتا ہے؟
Distance
Speed
Displacement
Velocity
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The shortest distance between two points is called displacement. Displacement is a measure of the straight-line distance between two points . It is a vector quantity. Key Point : The longest distance between two points is called the circumference (if the points are on a circle) or a diagonal (if the points are on a polygon or a rectangle).
ہوائی جہاز کا آئینہ ایک تصویر بناتا ہے جو ___ ہے؟
Real and Inverted
Virtual and Inverted
Real and Upright
Virtual and Upright
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
A plane mirror produces a virtual image , meaning it's not a real image that can be projected onto a screen. The image is also upright , meaning it's not inverted or flipped.

80°C
90°C
100°C
10°C
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The freezing point of water is 0°C (zero degrees Centigrade). The boiling point of water on the Centigrade scale ( also known as the Celsius scale ) 100°C (one hundred degrees Centigrade).
زمین کو ایک چکر مکمل کرنے میں کتنا وقت لگتا ہے؟
23 hours 59 minutes 59 seconds
24 hours 00 minutes 00 seconds
23 hours 56 minutes 04 seconds
24 hours 01 minutes 01 seconds
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The Earth takes approximately 23 hours, 56 minutes, and 4 seconds to complete one rotation on its axis, which is called a sidereal day. This is the time it takes for the Earth to rotate once relative to the fixed stars. The extra 4 minutes is due to the Earth's slightly ellipsoidal shape and the effects of the Moon's gravitational pull.

Fore brain
Cerebrum
Cortex
Frontal lobe
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The Frontal Lobe (part of the Cerebrum) controls reasoning, planning, and problem-solving.
More Details
Cerebellum → balance & coordination,
Medulla → involuntary actions,
Cerebrum → higher thinking functions, divided into 4 lobes (Frontal, Parietal, Temporal, Occipital).
گیس کے حجم اور پریشر کے درمیان کیا تعلق ہے؟
Directly Proportional
Exponentially Related
Not Related
Inversely Proportional
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
According to Boyle's Law , when temperature is constant, the pressure of a gas increases as its volume decreases, and vice versa. This means Pressure × Volume = Constant → they are inversely proportional.
متواتر جدول میں ادوار ____ ہیں؟
Vertical columns
Horizontal rows
Diagonal lines
Blocks
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Periods in the periodic table are horizontal rows (left to right).
There are 7 periods in total.
Elements in a period have the same number of electron shells but different chemical properties.
Groups are the vertical columns in the periodic table.
There are 18 groups .
Elements in the same group have similar chemical properties and the same number of valence electrons.
متواتر جدول میں عناصر کو ____ کے مطابق ترتیب دیا جاتا ہے؟
Increasing atomic mass
Decreasing atomic number
Both A and B
Increasing in atomic number
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The modern periodic table is arranged by increasing atomic number (number of protons). This arrangement resolves inconsistencies in earlier tables and groups elements with similar properties together.
آواز کی لہر کے لگاتار دو کمپریشن کے درمیان علیحدگی کو ____ کہتے ہیں؟
Time period
Frequency
Amplitude
Wavelength
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Wavelength is the distance between two consecutive points on a wave that are in phase. It is typically denoted by the symbol λ (lambda). Key Points:
Time period (T) is the time taken by the wave to complete one oscillation. Frequency (f) is the number of oscillations per unit time. Amplitude (A) is the maximum displacement of the wave from its equilibrium position.
