Heat required to raise the temperature of a given system is
here we know that
m = mass
s = specific heat capacity
= change in temperature
now as we know that
mass of wood = 5 kg
mass of aluminium pan = 2 kg
change in temperature = 45 - 20 = 25 degree C
specific heat capacity of wood = 1700 J/kg C
specific heat capacity of aluminium = 900 J/kg C
now here we will find the total heat to raise the temperature of both
So heat required to raise the temperature of the system is 257500 J
Answer:
The new speed is 1230.28 m/h
Explanation:
The jet airliner moving initially at 503 mph to the east
The wind is blowing at 855 mph in a direction 52° north of east
At first let us distribute the velocity of the wind into east component
and north component
→ The east component is 855 cos(52) m/h
→ The north component is 855 sin(52) m/h
Now we have two components of velocity in the east direction
and one component of velocity in the north direction
The new speed is the resultant of the east and north components
→ The east components are 503 m/h and 855 cos(52) m/h
→ The north component is 855 sin(52) m/h
Add the components of the speeds in direction of east
→ The east component = 503 + 855 cos(52) = 1029.39 m/h
→ The north component = 855 sin(52) = 673.75 m/h
Now we can find the new speed as a resultant speed of the east and
north components
→ The new speed =
→ The new speed = 1230.28 m/h
<em>The new speed is 1230.28 m/h</em>
