ICS Part 1 Physics English Medium Chapter 4 Online Short Questions Test with Answers

Question # 1

What are the essential conditions for conservative field?

Ans 1: For a field to be conservative, energy should be conserved and work should be independent of the path followed.As in case of work done along a path in the gravitational field of earth.

Question # 2

Write down two sources of energy which are renewable

Ans 1: The renewable sources of energy are:
1. Hydroelectric Energy
2. Wind Energy
3. Tides Energy
4. Biomass Energy
5. Sunlight Energy

Question # 3

How sunlight is directly converted into electricity by solar cells?

Ans 1: By using semiconductor devices,the solar cell also called photo voltaic cell, sunlight can be directly converted into electricity. These solar cells are made of silicon wafers. Electron in the silicon gain energy from sunlight to create a voltage. Voltage can be increased by increasing the number of solar cells.

Question # 4

An object has one joule of potential energy.Explain what it means.

Ans 1: It means that work has been done on the body by the force of 1 N which has lifted the body through a distance of 1 m.This work has been stored in the body in the form of P.E. Which is 1J.

Question # 5

What is a machine ? Discuss the input and output and efficiency of a mechanical machine ?

Ans 1: Machine:A machine is a thing or device with the help of which we can do more work than we can do by hands.
Input of Mechanical machine:The amount of work dine on a machine by a given effort force is known as input of machine.
Input = effort *effort arm
Input = P*d
Output of Mechanical Machine:The amount of work done by a machine on the load (weight) is known as output of the machine
output = load * load arm
output = w*d
Efficiency:The ratio of output and input of a machine is known as efficiency
Efficiency:Output / input
n = w*d/ p*d

Question # 6

How can we gain energy from tides?

Ans 1: The tides raise the water in the sea roughly twice a day.If the water at the high tides is trapped in a basin by constructing a dam, then it is possible to use this as a source of energy. There dam is filled at high tide and water is released in a controlled way at low tide to drive the turbines and generate electricity.

Question # 7

Differentiate between geyser and aquifer.

Ans 1: Geyser isa hot spring that discharges steam and hot water, intermittently releasing an explosive column into the air

Aquifer is a layer of rock holding water that allows water to percolate through it with pressure.

Question # 8

Define conservative and non-conservative fields?

Ans 1: Conservative field: The field in which work done along a closed path is zero is called conservative field. For Example, Earth's gravitational field

Non-Conservative fields:The field in which work done along a closed path is not zero is called non-conservative field. For Example, field of frictional force.

Question # 9

Define and explain work ?

Ans 1: Work:The scalar product of force and displacement is known as work.
Explanation:Consider a force 'F' is acting on a body of mass 'm' and moves it form point 'A' to point 'B' through a displacement 'd'
Work = Force * displacement
W = F*d cosO

Question # 10

What is Salter's duck?

Ans 1: Salter's duck is a device which can be used to utilize the water waves energy and to generate electricity .It consists of two parts
1. Duck float
2. Balance float
The wave energy makes duck float move relative to the balance float. The relative motion of the duck float is then used to run electricity generators.
