Answer: 1008 metres
Explanation:
speed of swimmer = 2.8 m/s
Time taken = 6minutes
(since speed is in metres per second, convert time in minutes to seconds
If 1 minute = 60 seconds
6 minute = 6 x 60 = 360 seconds
distance = ?
Since, speed is the distance covered divided by time taken in seconds, thus
Speed = distance / time
Distance = speed x time taken
distance = 2.8m/s x 360
= 1008 metres
Thus, the swimmer cover a distance of 1008 metres
A: Some ice will turn into liquid water.
The energy to vaporize the water at its normal boilng point (100°C) is the vaporization latent heat.
The vaporization latent heat of water is 2257 J/ g (you can find it in a textbook, tables or internet).
So, with 955 kJ you can vaporize this amount of water:
[995 kJ * 1000J/kJ ] / 2557 J /g = 389.13 g
Use the density to convert to volume: D = M / V => V = M / D
V = 389.13 g / 1.00 g / ml = 389.13 ml, which rounded to 3 significant figures is 389 ml
Answer: 389 ml
