(10 sin 30°)/(10+10 cos 30°) |
| Answer» (10x1/2)/10+10√3= 5/(10+5√3)=5/5(2+√3)= 1/(2+√3)<br>Ans is 10/10+5√3<br>But cos 30°= √3/2So it will be (10+10X√3/2)<br>(10×1/2) / (10+10×1/2) = 5/(10+5) = 1/3 = 0.333333333...... ans | |

Ch 5 exercise ques 5.18 |
| Answer» As the body continues to move without change in velocity, we consider it as zero impulse.This can be proved numerically.m1 = m2 = 0.05 kg U1 = V1 = 6m/s U2 = V2 = -6 m/sImpulse = Force × time =ma × t = m( v-u)/t × t = m(v - u) Impulse on 2 by 1 = m1 (v1 -u1) = m1(0) =0Impulse on 1 by 2 = m2(v2-u2) =0 | |

Moment of inertia of solid sphere... ✍✍✍✍ |
| Answer» Hello bhai....kaise ho?? Pahchana?...padhai kaise chal rahi??.....ghar me sab badhiya?<br>Moment of inertia of sphere is normally expressed as;\tI = ⅖ MR2\tHere, r and m are the radius and mass of the sphere respectively. Students have to keep in mind that we are talking about the moment of inertia of a solid sphere about its central axis above. Additionally, if we talk about the\xa0moment of inertia\xa0of the sphere about its axis on the surface it is expressed as;\tI = 7/5 MR2\t | |

the density of mercury is 13.6 g/cm3. convert this to kg/m3 |
| Answer» SI unit of density is Kg/m³1 m = 100 cm => 1 cm = 10-² m1 Kg = 1000g => 1g = 10-³ Kgnow,13.6 g/cm³ = 13.6 × ( 10-³)/(10-²)³ Kg/m³= 13.6 × 10-³/10^-6 Kg/m³= 13.6 × 10^(-3 + 6) Kg/m³= 13.6 × 10³ Kg/m³ | |

Expression for energy stored in string |
| Answer» Hooke’s Law, F = -kx, where F is the force and x is the elongation.The work done = energy stored in stretched string = F.dxThe energy stored can be found from integrating by substituting for force,and we find,The energy stored = kx2/2, where x is the final elongation.The energy density = energy/volume= (kx2/2)/(AL)=1/2(kx/A)(x/L)= 1/2(F/A)(x/L)= 1/2(stress)(strain) | |

Convert into 10 joule to into erg |
| Answer» 1J= 10⁷erg 10J = 10×10⁷ erg = 10⁸erg<br>we know, 1 Joule = 1 Kg m²/s²1 erg = 1 g cm²/s²so, 1 Joule = 1Kg m²/s²= {1000 g} {100cm}²/s². [ 1kg = 1000g and 1m = 100cm]= 1000 × 10000 g cm²/s²= 10000000 erghence, 1 Joule = 107 ergso, 10 Joule = 10 × 107 erg = 108 erg | |

|vector A+vector B|is less than |vector A|+|vector B| |
| Answer» True, But not always, because magnitude of any vector or vectors taken separately is always greater than that of which are taken together, But this idea becomes wrong when vectors which are taken together have same sign because in this case there is effective addition of magnitude of both vectors and then there result is equal to that which are taken seperately. | |
