Answer:

Super insulation are obtained by using layers of highly reflective sheets separated by glass fibers in an vacuumed space. Radiation heat transfer between any of the surfaces is inversely proportional to the number of sheets used and thus heat lost by radiation will be very low by using these highly reflective sheets which will an effective way of heat transfer.

Train levels a station and travels north at 60km/hr. Two hours later, a second train leaves on a parallel track and travels nort
Amanda [17]

Answer: they would be 300 miles from the station.

Explanation:

At the point where both trains meet, they would have covered the same distance.

Let t represent the time spent by the first train in covering this distance.

Distance = speed × time

The first train leaves the station and travels north at 60km/hr.

Distance covered by the first train is

60 × t = 60t

Two hours later, a second train leaves on a parallel track and travels north at 100km/hr. Time spent by the second train in covering this distance is (t - 2) hours

Distance covered by the second train is

100(t - 2) = 100t - 200

Since both trains covered the same distance, then

100t - 200 = 60t

100t - 60t = 200

40t = 200

t = 200/40

t = 5 hours

The distance that they would be from the station is

60 × 5 = 300 miles
