Answer:
It must be moving at an angle with East towards North
Explanation:
As we know that boat headed towards North while river is flowing towards East
So here the resultant velocity of boat is vector sum of velocity of river and velocity of boat.
So we will find the vector resultant as
here we know
= velocity of boat towards North
= velocity of river towards East
now if we add two vectors along North and and east then the resultant must be between North and East so the boat will move at some angle with East towards North
Answer:
223.25
Explanation:
The thermal conductivity of an object is defined as the measure or the ability of the object to transfer heat or conduct heat through its body.
In the context, the thermal conductivity of the material is given as
And it is given that :
1 Btu = 1055 J
1 ft = 0.3048 m
We know that 1 h = 3600 s
So the thermal conductivity of the material in is :
Thermal conductivity :
= 223.25
Answer:
Explanation:
We can use the equation for the speed
where x is the distance and t the time. In this case we know that the time spent was 2 hours and the distance was 150km. By replacing we have
