Answer:
The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted. Nothing happens to the energy. It does not change form, since energy has no form. ... If the energy was moving, it gets stored or re-transmitted elsewhere. Using energy means controlling its movement, rather than consuming it.
Answer:
900 m
Explanation:
Given that,
A hiker travels 300 m [N], turns around and hikes 550 m[S], and then finds out he has to hike back another 50.0 m [N].
We need to find the total distance travelled by the hiker.
Let north be positive and south be negative direction.
Distance = total path covered
D = 300 + 550 + 50
D = 900 m
So, the required distance is equal to 900 m.
