Yogita Ingle 7 years, 2 months ago

Principle of Conservation of Mechanical Energy states that the energy can neither be created nor destroyed; it can only be transformed from one state to another. Orthe total mechanical energy of a system is conserved if the forces doing the work on it are conservative.

K=p2\2m kinetic energy =300% of k =3k. Final energy become k'=k+3k=4k final momentum p'=√2mk =√2m*4k =2p. %increase in momentum =p'-p\p*100=100%

What is efficiency

Posted by Rahul Yadav 7 years, 2 months ago

CBSE > Class 11 > Physics

1 answers

Priya Dharshini ☺☺ 7 years, 2 months ago

Efficiency is a measure of how much work or energy is conserved in a process. In many processes, work or energy is lost, for example as waste heat or vibration. The efficiency is the energy output, divided by the energy input, and expressed as a percentage. A perfect process would have an efficiency of 100%.

Posted by Rani Layek 7 years, 2 months ago

Priya Dharshini ☺☺ 7 years, 2 months ago

Projectile motion is a form of motion experienced by an object or particle that is thrown near the Earth's surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are assumed to be negligible).

ANSWER

if radius of the earth shrinks 2% mass remaining constant then how would the value of acceleration due to gravity change?

Posted by Meenal Meshram 7 years, 2 months ago

CBSE > Class 11 > Physics

1 answers

Priya Dharshini ☺☺ 7 years, 2 months ago

The acceleration due to gravity at the surface of earth is g = G m / R2 . The radius of eath decreases by 2 %, therefore R' = R - 0.02 R = 0.98R. Now acceleration due to gravity will be : g' = GM / ( 0.98 R )2 = 1.04 g Percentage increase in acceleration due to gravity [(g' - g )/g ] x 100 = 4 %
