If you want to learn more about the nature and properties of matter and energy or you're simply preparing for a Physics exam, these Physics past questions and answers are ideal for you.
II only
III only
I & IV only
II & III only
Correct answer is B
- I & II are in neutral equilibrium. They will roll continuously on the table
- III is a body with high centre of gravity (unstable)
- IV is a body with high centre of gravity (stable)
"Sum of all forces acting on a body is zero." This condition represents equilibrium'
First condition
Second condition
Third condition
Fourth condition
Correct answer is A
First condition
9.6 × 10\(^6\)N/m\(^2\)
9.5 x 10\(^5\)N/m\(^2\)
9.4 x 10\(^6\)N/m\(^2\)
9.5 x 10\(^6\)N/m\(^2\)
Correct answer is A
P = Pa + ρgh = (1.00 × 10\(^5\)) + (950 × 10 × 1000)
P = 10\(^5\) + (95 × 10\(^5\)) = 10\(^5\)(1 + 95) = 96 × 10\(^5\)
P = 9.6 × 10\(^6\) N/m\(^2\)
Efficiency of conduction in liquids and gases compared to solids is
less efficient than solid
more efficient than solids
equally efficient to solids
efficiently may vary
Correct answer is A
Efficiency of conduction in liquids and gases compared to solids is less efficient than solid.
I only
II only
III only
I & III only
Correct answer is C
- the total energy at any point is a combination of the P.E and K.E
- the sum of PE and KE at any point is always constant not the ratio of P.E to K.E
