Question 2

What is electrical resistance?

Accepted Answer

How much a material opposes the flow of electrical current

Answer

Electrical resistance is the opposition to the flow of electric current in a circuit. It is measured in Ohms (Ω). Materials with high resistance slow the current; those with low resistance (conductors) allow it to flow easily.

Question 3

What is the difference between a herbivore and a producer in a food chain?

Accepted Answer

A producer makes its own food; a herbivore eats plants

Answer

Producers (usually plants) make their own food through photosynthesis. Herbivores are animals that consume plants (primary consumers). In a food chain: plant (producer) → herbivore → carnivore.

Question 4

What does it mean when forces on an object are 'balanced'?

Accepted Answer

The object stays still or continues at constant speed

Answer

When forces are balanced (equal in size and opposite in direction), there is no resultant force. The object either stays still or moves at a constant speed in a straight line (Newton's First Law).
