ANDREW2EIC: Attempt this:focal lenght=15 mirror's equation=>1/f=1/u + 1/v since the image produced is 4 times the object.therefore 1v=4u. So, 1/15=1/u + 1/4u u=75/4 u=+18.75cm(since it's a concave mirror) |

ANDREW2EIC:wao @andrew,i've gained from that explanation of yours... I think it can also be solved this way, from the law of conservation of energy { F=Mv/t} since f=30N,M=0.075kg,t=0.05 then make v the subject of the formula and solve.the final answer will be 20 N/s |

buzyguy: Benzene is sp2 hybridized while ethyne is sp hybridized.the more the pi-bond encounterd the more the reactivity.the pi-bond distorts da shape nd increase da bond angle by reducing the repulsion btwn da molecules.hop itz wel clear!you're correct.besides,what school are you aspiring and what course? |
