To solve this problem it is necessary to apply the concepts related to heat exchange in the vegetable and water.
By definition the exchange of heat is given by
where,
m = mass
c = specific heat
= Change in temperature
Therefore the total heat exchange is given as
Our values are given as,
Total mass is = 200lb ,however the mass of solid vegetable and water is given as,
Replacing at our equation we have,
Therefore the heat removed is 22411.2 Btu
Answer:
Explanation:
First displacement of the particle is given as
= 11 m at 82 degree with positive X axis
so we can say
resultant displacement of the particle after second displacement is given as
r = 8.7 m at 135 degree with positive X axis
so we can say
now we know that
now we have
so we will have
so angle of the second displacement is given as
Gravity is an example of friction. If we didn't have gravity, we would be flying all over the place. Also, friction keeps us from sliding on the ground and falling.
