Experiment Steps
- Check the transistor terminals and status.
- Assemble the circuit in Fig. 1.1 and measure the following values:
- VE = 0V
- VC = 5.29V
- R3.9K = 3.85KΩ
- VBE = 0.65V
- VCE = 5.29V
- R1.5M = 1.5MΩ
- IE = IC = 0.97mA
- Place a bulb near the transistor for 30 seconds, then observe and record:
- VCE = 5.18V
- VE = 0V
- IC = 0.98mA
- VC = 5.18V
- Assemble the circuit in Fig. 1.2 and repeat Step 2.
- Assemble the circuit

The Vastness and Composition of the Universe
- The universe is predominantly made up of dark energy (68%) and dark matter (27%), with normal matter constituting less than 5%.
- Galaxies are not uniformly distributed but form a foamy structure, concentrated in sheets and filaments surrounding vast cosmic voids.
- The Milky Way belongs to the Local Group, a cluster of about 30 galaxies, with Andromeda as our nearest major galactic neighbor.

Literary Theory and Criticism: A Comprehensive Overview
Chapter 2: Before and During New Criticism
Early Approaches to Literary Interpretation
- Impressionistic Criticism: Focused on personal responses to literature, moralizing, and reading aloud.
- Writer’s Milieu: Considered the writer’s circle of friends and influences from other writers and artists.
Key Concepts of New Criticism
- Close Reading: Emphasized detailed, careful attention to the text itself, focusing on the words on the page.
- Intrinsic Criticism: Advocated for focusing on the literary work itself,
Understanding Force, Motion, and Momentum: Exploring Newton’s Laws
1. Motion Under Zero External Unbalanced Force
Answer: An object can travel with a non-zero velocity even when experiencing zero net external unbalanced force. This occurs when the object maintains a constant velocity in a specific direction, resulting in no net force acting upon it. To alter its state of motion, a non-zero external unbalanced force must be applied.
2. Dust Removal from a Carpet
Answer: The inertia of dust particles causes them to resist changes in their state of rest. When
Gravity and Buoyancy: A Comprehensive Guide
Universal Law of Gravitation
Every object in the universe attracts other objects by a force of attraction, called gravitation, which is directly proportional to the product of masses of the objects and inversely proportional to the square of distance between them. This is called Law of Gravitation or Universal Law of Gravitation.
