Answer:
4.34 mi at
north of east
Explanation:
The displacement of an object in motion is a vector connecting its initial position to the final position of motion.
In this problem, the man has 2 different motions:
- 3.50 mi due east
- 2.57 mi due north
We can take the east direction as positive x-direction and north as positive y-direction, so these two motions can be written as:


Since the two motions are perpendicular to each other, the resultant displacement can be found by using Pythagorean's theorem; therefore:

We can also find the direction using the equation:

And therefore,

Answer: There is no change in temperature when heat is given out or taken in by the object
Explanation:
The heat capacity of an object is infinite when it undergoing phase transition since the heat is ued in changing the state of the substance and ntot in raising the teperature of the substiance. Thus, heat capacity is infinite during change of state. This is known as latent heat. The correct option is
There is no change in temperature when heat is given out or taken in by the object
