آئن اسٹائن کے ذریعہ متعارف کروائے جانے والے مندرجہ ذیل میں سے کون سے تصورات نے جدید کوانٹم میکانکس کی بنیاد رکھی؟
Photoelectric effect
Principle of Relativity
Theory of General Relativity
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Einstein's explanation of the photoelectric effect (1905) introduced the concept of quantized energy (photons) , laying the foundation for quantum mechanics. This discovery led to Einstein receiving the Nobel Prize in Physics (1921) and helped develop wave-particle duality in quantum theory.
یہ دو لاشیں غیر صفر کی رفتار کے ساتھ مخالف سمتوں میں آگے بڑھ رہی ہیں ، مندرجہ ذیل میں سے کون سا بیان صحیح ہے؟
Relative velocity <= Absolute velocity
Relative velocity = Absolute velocity
Relative velocity < Absolute velocity
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
When two bodies are moving in opposite directions , their velocities are added to find the relative velocity.
Let's say the velocities of the two bodies are v1 and v2.
Relative velocity = v1 + v2
Since both velocities are non-zero and in opposite directions, the relative velocity will be greater than the absolute velocity of either body.
So, the statement " Relative velocity > Absolute velocity " is true.
کیپلر کے قانون کی مدت کا کیا تعلق ہے؟
Time period and semi-major axis
Time period and semi-minor axis
Time period and eccentricity
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Kepler's Third Law of Planetary Motion states :
T² = (4π²/G * (M₁ + M₂)) * a³
Where:
T = Orbital Period
a = Semi-major Axis
G = Gravitational Constant
M₁ and M₂ = Masses of the two bodies (e.g., planet and star)
This law shows that the square of the orbital period (T) is proportional to the cube of the semi-major axis (a).
اگر کوئی مصنوعی سیارہ زمین کی سطح کے قریب سے گردش کر رہا ہے تو ______؟
Its kinetic energy will be maximum
Its speed is minimum
Its speed is minimum
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
When a satellite orbits close to the Earth's surface, it must travel faster to avoid falling towards the Earth due to gravity. This means its speed is maximum.
Since kinetic energy (KE) is proportional to the square of the speed (v), the kinetic energy will also be maximum:
KE = (1/2)mv^2
where m is the mass of the satellite.
So, when a satellite orbits close to the Earth's surface, its kinetic energy will be maximum.

None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
At resonance in a series LCR circuit, the inductive reactance (XL) equals the capacitive reactance (XC), so the impedance (Z) is equal to the resistance (R).
Z = R
The power factor (PF) is the ratio of the real power (P) to the apparent power (S):
PF = P / S = R / Z
Since Z = R at resonance, the power factor is:
PF = R / R = 1
