Where I work, the water that is coming into the pipes for our consumption is the same water that is routed to the fire hydrants around the building I work. We have been told the water is safe. Does anyone know if it is ok?
MEASURE OF INSULATION ABILITY (As in reflective window coverings) a measure of the ability of a material such as insulation to retard heat flow. A higher number indicates better insulating properties.
U 25m/s and Q 40 5 degree with observe of to horizontal Usin45 and Ucos45 are vertical and horizontal speed enable time to achieve max. height be T so in easy words gravitational acceleration acts vertically it truly is 'g' by regulation of action 0 Usin45 - gT T Usin45/g Ta million.8 sec approx. if g taken 9.8 (answer A) enable height be H 0 - (Usin45)^2 -2gx (third regulation of action) x (Usin45)^2/2g x 15.94m approx. y (Ucos45)T + (aT^2)/2 on condition that a 0 (there is not any linear acceleration) y (Ucos45)T + 0 y 31.80 2 meter (answer B) answer C At time T projectile is at max height so gravitational acc. will change into 0 for an instantaneous. merely after T 'g' route inverts i.e. directed downward at the same time as horizontal speed element continues to be similar for entire projectile action vertical speed will also change into 0 for an instantaneous and merely after T vertical speed element is directed downward answer D i imagine you could do it your self thanx
