KMU CAT PAST PAPERS AND SYLLABUS
چار آپشن میں سے کسی ایک پر کلک کرنے سے جواب سرخ ہو جائے گا۔
- 2π
- 30 𝜋
- 100 𝜋
- 3000π
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
To find the angle in radians per second, first convert the rpm (revolutions per minute) to radians per second.
3000 rpm = 3000/60 revolutions per second = 50 revolutions per second.
Each revolution is 2π radians.
So,
50×2π=100π radians per second.
- Is zero
- Is constant but not zero
- Increases uniformly with respect to time
- Is proportional to the displacement of mass from a fixed point
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
According to Newton's second law,
F=ma, a constant non-zero force results in uniform acceleration of the mass.
مندرجہ ذیل میں سے کون سا دو ویکٹروں کے ویکٹر کی پیداوار کی مثال ہے؟
- Linear momentum
- Angular momentum
- Force
- Electric flux
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The vector product (cross product) of two vectors gives a vector that is perpendicular to both original vectors.
Angular momentum is a vector product of position and linear momentum vectors.
- Momentum
- Acceleration
- Force
- Work
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Energy and work have the same dimensional formula,
Both represent the ability to perform work or cause a change in energy.
- PbCl₂
- PbCl₄
- Pb₂Cl₄
- PbCl
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
PbCl₂ (lead(II) chloride) is ionic.
Lead(II) chloride forms an ionic lattice structure with chloride ions,
while PbCl₄ is a covalent complex.
- Centriole
- Microfilament
- Cilia and flagella
- Spindle fiber
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Cilia and flagella have a characteristic "9+2" arrangement of microtubules: nine outer pairs and two central single tubules.
- Lipid
- Proteins .Carbohydrates
- Both a and b
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The selective permeability of a membrane is primarily due to its lipid bilayer and the embedded proteins.
Lipids form the basic structure of the membrane, while proteins play roles in transport and signaling.
- Enzymes
- Protein
- Sugar
- Lipids
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The smooth endoplasmic reticulum (SER) is involved in the synthesis of lipids, including phospholipids and steroids.
- Endoplasmic reticulum
- Golgi apparatus
- Mitochondria
- Glyoxisome
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The glyoxisome is a single-membrane organelle.
In contrast, the endoplasmic reticulum, Golgi apparatus, and mitochondria all have double membranes.
- 1,2 glycosidic linkage
- 1,3 glycosidic linkage
- 1,4 glycosidic linkage
- 1,5 glycosidic linkage
