Answer:
The amount of time needed for this heating to occur is 126.25 min
Explanation:
Given;
power required to heat the room = 2kW
volume of the room = 5 m X 5 m X 6 m = 150 m³
atmospheric pressure at sea level = 101 Kpa
Internal energy available in this room, E = PV
= 101 Kpa*150m³
= 15,150 Kpa.m³ = 15,150 KJ
P*t = E
where;
t is the time required to heat this room
1 kW = 3600 kJ/h
2 kW = 7200 kJ/h
Therefore, the amount of time needed for this heating to occur is 126.25 min
Answer:
75m
Explanation:
Given parameters:
Distance covered by the boat = 15m
Time taken = 8s
Unknown:
Distance covered by the boat in 40s = ?
Solution:
To solve this problem, we need to find the speed of the boat first;
Speed =
Insert the parameters and solve;
Speed = m/s
Now;
The boat will travel;
Distance = speed x time
Distance = x 40 = 75m
