Explanation
The pattern for each equation is as follows: Subtract the second number from the first number. Add the first and second numbers. Combine the two results to form a new number. Let's apply this logic to the given examples:
7 + 2 = 59
7 - 2 = 5
7 + 2 = 9
Combined: 5 followed by 9, which is 59.
5 + 3 = 28
5 - 3 = 2
5 + 3 = 8
Combined: 2 followed by 8, which is 28.
9 + 1 = 810
9 - 1 = 8
9 + 1 = 10
Combined: 8 followed by 10, which is 810.
2 + 1 = 13
2 - 1 = 1
2 + 1 = 3
Combined: 1 followed by 3, which is 13.
Solving for 5 + 4
Applying the same logic to 5 + 4:
5 - 4 = 1
5 + 4 = 9
Combined: 1 followed by 9, which is 19 .

اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
To find the answer, we need to calculate the percentage step by step:
20% of 30% = (20/100) × (30/100) = 6/100 = 6% 10% of 6% = (10/100) × (6/100) = 0.6/100 = 0.6% So, the correct answer is: 0.6%
ہلکا پھلکا ہوتا ہے جب _____؟
Opposite charges in different clouds break down the resistance offered by the intervening air
Molten lava spread on the floating clouds
Earth pressure fall on the floating clouds
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Lightning occurs when opposite electrical charges in clouds (or between clouds and earth) discharge.
This sudden discharge produces the flash of light we see as lightning.
عام طور پر ابر آلود راتوں میں ٹھنڈ نہیں بنتا ہے۔ وجوہات کیا ہیں؟
Clouds generate air currents and disturbances which stop cooling
Clouds prevent radiation and therefore help the ground to maintain heat
Clouds absorb heat which has been sucked by the clouds from earth
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
On cloudy nights, clouds act like a blanket , trapping heat radiated from the earth.
This prevents the ground temperature from falling low enough to form frost.
ریفریکیٹ انڈیکس کی عین مطابق پیمائش کے لئے مندرجہ ذیل میں سے کون سا آلات استعمال کیا جاتا ہے؟
Spectrometer
Micrometer
Photometer
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The instrument used for the precise measurement of refractive indices is a spectrometer .
A specific experiment using a spectrometer and a prism allows for the calculation of a material's refractive index.
پانی اونچائی پر 100 سینٹی گریڈ سے نیچے کیوں ابلتا ہے؟
Water available at higher altitudes is purer than at the plains
Pollution-free air at higher altitudes increases the calorific value of fuel used
The atmospheric pressure at higher altitudes is lower as compared to that at sea level
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Lower pressure means water molecules need less energy to escape as vapor.
This causes water to boil at a temperature below 100°C .
برقی چارجز میں کشش اور پسپائی کا قانون کس نے دریافت کیا؟
Einstein
Coulumb
Gullelio
Newton
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Charles-Augustin de Coulomb , a French physicist, discovered the law of attraction and repulsion in electric charges in the 18th century. His law, known as Coulomb's Law, states that the force between two charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
چھوٹے برقی دھاروں کو درست طریقے سے پیمائش کرنے کے لئے مندرجہ ذیل میں سے کون سا آلات استعمال کیا جاتا ہے؟
Ammeter
Galvanometer
Fluxmeter
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
A galvanometer is a highly sensitive instrument used to detect and measure very small electric currents , often in the microampere range .
It can also detect the direction of the current based on the needle's deflection.
جوہری ری ایکٹرز میں چین کے رد عمل کو مندرجہ ذیل میں سے کون سا کنٹرول کرتا ہے؟
Moderator
Rods
Ions
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
They are used to control the rate of fission in a nuclear reactor.
They work by absorbing neutrons , which are the particles that trigger the fission of uranium or plutonium atoms.
Control rods are typically made of neutron-absorbing materials like boron, cadmium, or hafnium.
