I dont think so.... if u have so much time than ok. Otherwise just practice important question. 3hrs sample paper solving will remove ur whole time to do revision of topics u know. If u couldnt do it good then again tension and pressure. Better use sample papers for board exams

Sachin B 7 years, 1 month ago

Hello Dear. Given :- Ratio of the Resistance of two bulbs P and Q = 1 : 2. Let the Resistance of the bulbs P and Q be x and 2x respectively. ∵ Current remains same in the series, ∴ Let the current in the Resistors P and Q be I. Now, For Bulbs P, Power = P₁ Current = I Resistance = x ∵ Power = I² × R ∴ P₁ = I² × x For Bulb Q, Power = P₂ Current = I Resistance = 2x ∴ Power(P₂) = I² × 2x ∴ Ratio of the Powers, P₁/P₂ = I²x/I²2x P₁/P₂ = 1/2 ⇒ P₁ : P₂ = 1 : 2 Hence, the Ratio between the Power Dissipation of the bulb P and bulb Q is 1 : 2.

Stress and strain

Posted by Veshali Kathuria 7 years, 1 month ago

CBSE > Class 11 > Physics

1 answers

Yogita Ingle 7 years, 1 month ago

Stress: In mechanics, stress is defined as force applied per unit area. It is given by
σ = F/A
where, σ<amp-mathml data-formula="\[ \sigma \]" inline="" layout="container"></amp-mathml> is the stress applied
F is the force applied
A is the area of force application
Stress is expressed as N/M².
Strain: The strain is the amount of deformation experienced by the body in the direction of force applied, divided by initial dimensions of the body. The relation for deformation in terms of length of a solid is given below.
ϵ = δl/ L
where, ϵ<amp-mathml data-formula="\[ \epsilon \]" inline="" layout="container"></amp-mathml> is the strain due to stress applied
δl<amp-mathml data-formula="\[ \delta \]" inline="" layout="container"></amp-mathml> is the change in length
L is the original length of the material.
