Solve above question correctly |
|
Answer» S O L U T I O N The relation between length and AREA is R = ρl/A _[i] Where ρ being specific resistance is the proportionality constant and DEPENDS on the NATURE of MATERIAL. [i] Length = L/2, area = 2A Putting in Eq [i] we have R = ρ( L/2 )/2A = ρL/4A [ii] Length = L, area = A Putting in Eq [i] we have R = ρL/A [iii] Length = 2L area = A/2 Putting in Eq [i] we have R = ρ 2L/ A/2 = 4ρL/A As it is understood from above, resistance is minimum only in option B! |

Why both electric potential and electric potential difference are scalar quantity |
|
Answer» The Electric Potential is DEFINED as the amount of work-done PER UNIT positive charge to bring from infinity to that POINT under the influence of the primary charge only. And workdone is defined as the dot product of FORCE and displacement which is a scalar quantity. Thus Electric potential is a scalar quantity. |

if an object is projected under gravity but in air resistance then which time will be greater ? upward journey time or downward journey time? |
|
Answer» Answer: Explanation: TIME of Ascent: The time taken by body thrown up to reach maximum height H is called as time of ascent. Let t₁ be time of ascent. at maximim height, its velocity is zero, V=0 hence, V=u-gt O=u-gt₁ t1=u/g (1) Time of descent: after reaching the maximum height, the body begins to travel downwards and reaches the ground. The time taken to by a freely falling body to touch the ground is called time of descent. Initial velocity for downward JOURNEY is zero u= 0 let t₂ be time of descent. Initial velocity for downward journey is zero 9 u= 0 let t₂ be time of descent. s=ut+1/2 gt² h=0+1/2gt₂² t2=√2h/g but, h=u²/2g so, we get t₂=√2u²/2g 65 --(2) from equation 1 and 2 we can say the time of ascent is equal to time descent in the CASE of bodies moving under gravity. |

A spherical mirror has a radius of curvature -40 cm. An object ofsize 7 cm is placed 10 cm from it, what is the nature, size andposition of the image? |
|
Answer» Explanation: Given that, Height h=3cm Distance u=−15cm Radius = 10cm Now, the focus F= 2 r
f= 2 10
=5cm Now, by using mirror equation
f 1
= 1
+ u 1
5 1
= v 1
− 15 1
v 1
= 5 1
+ 15 1
v= 15
cm v=4cm So, the image will be formed between focus and pole Now, the magnification is m= u −v
m= 15 4
Now, m= h h ′
15 4
= 3 h ′
h ′ = 15 12
h ′ =0.8 Hence, the height of image is 0.8 cm and distance of image is 4 cm please mark as brainlist |
