Answer: 31.85 m/s
Explanation:
Since we are talking about constant acceleration, we can use the following equation to find the speed 
of the rocket:
Where:
is the distance the rocket has traveled
is the time in which the rocket has traveled the distance 
Solving the equation with the given data:
This is the rocket's speed
Answer:
1.24 m/s
Explanation:
Metric unit conversion:
9.25 mm = 0.00925 m
5 mm = 0.005 m
The volume rate that flow through the single pipe is
This volume rate should be constant and divided into the 4 narrower pipes, each of them would have a volume rate of
So the flow speed of each of the narrower pipe is:
Answer: A. Sediment
Eutrophication is a phenomena in which a water body gets enriched with minerals and nutrients frequently entered into water body due to run-off from the land, which facilitates dense growth of plants especially on the superficial layers of water body. Decaying organisms, fertilizers and pollution all add nutrients and minerals necessary for plant growth specifically remain floating on the superficial layers of water where plant growth takes place but sediments gets settled at the bottom of the water body, the minerals present in it remain settle at the bottom and hence, does not contribute to eutrophication.
Answer:
Explanation:
Let mass of ice required is m kg
Heat gained by ice to attain zero degree
= m x 14.1 x 2100
= 29610m J
Heat gained by ice to melt = m x 3.34 x 10⁵ J
= 334000m J
Heat gained by water at zero degree to warm up to 27 degree
m x 4190 x 27 =113130 J
Total heat gained = 476740m J
Heat lost by hot water to cool up to 27 degree
.24 x 4190 x ( 75.8 - 27 )
= 49073.28 J
Heat lost = heat gained
476740 m = 49073.28
m = 49073.28/476740 kg
=102.93 gm
