as we know tha momentum is product of mass and velocityi.e p=mv but here in this question velocity changes from 5m/s to 20 m/s so here formula becomes
p=(final velocity -initial velocity )mass
so (20-5)6=90kgm/s ANS
Answer:the H2O and O2 produced have the same mass as the original H2O2
I’m pretty sure it’s a starting point... unless it’s asking for an actual object
<span>The centripetal force that keeps the lady bug moving in a circle is FRICTION. The Centripetal Force</span><span> is a net force acting on an circling object that sustains constant circular motion. </span>It opposes the motion by acting in opposite direction. A ladybug sits at rest on a turntable that is rotating, during this motion, the ladybug's acceleration vector points <span>toward the center of the turntable.</span>
Answer:
let distance be D km
total time taken, T (hrs) = D/30 + D/50
Average speed , V = total distance/ total time = 2D/T = 2/(1/30+1/50) = 37.5 km/hr
