Section A

Q1. Explain the difference between Prokaryotic cell and Eukaryotic cell.

Q2. What do you mean by Uniform Motion and Non- Uniform Motion? Draw Graph of each.

Q3. A car moves with a speed of 55km/hr and suddenly applies brakes to stop the car. It take 15secs for the car to come at rest. Find the distance covered by the car if the rate of retardation is 2m/s2.

Q4. A circular ground has a radius of 15 meters. The cyclist takes 5seconds to complete a round of the ground. Find the speed of the cyclist.

Section B

Q1. Explain the properties of Solids, Liquids and Gases on basis of cohesive force, compressibility and movement of particles in them.

Q2. Write the functions of Lysosomes, Gogli Bodies and Smooth Endoplasmic Reticulum.

Q3. Write difference between Displacement and Distance. Also show how speed and velocity are different quantities?

Q4. Explain Latent Heat of Fusion. How much energy is given out to convert solid Ice into liquid water in one kilograms of Ice?

Q5. On a 120km track, a train travels the first 30kms at a uniform speed of 30km/hr. How fast must the train travel the next 90 kms in order to have a average speed of 60km/hr for the entire trip?

Q6. In what way can the velocity of an object be changed? Why does a body in uniformly circular motion always have acceleration?

Section C

Q1.

From the following figure, find out:-

a) What type of motion is seen from O to A and A to B?

b) Find Acceleration from B to C and also from C to D.

c) Total Distance from O to D by the body.
