Answer:
v = 2.5 mi/h
Explanation:
The velocity of an object is defined as the time rate of change of its position. In other words the velocity of an object is just a ration of displacement covered by the object to the time taken by the object, to cover that distance. So, in this case we will use the same formula or equation to calculate the velocity of the man. The formula is as follows:
v = s/t
where,
v = velocity of the man = ?
s = distance of the trail = 5 miles
t = time required to complete the trail = 2 h
Therefore,
v = 5 miles/ 2 h
<u>v = 2.5 mi/h</u>
Because it is how fast it goes and it depends on the speed
Answer:
Light travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum—a completely airless space. (Sound, on the other hand, must travel through a solid, a liquid, or a gas.)
Explanation:
Metals are giant structures of atoms held together by metallic bonds. “Giant” implies that large but variable numbers of Atoms are involved - depending on the size of the bits of metal. most metals are close packed - that is, they fit as many items as possible into the available volume.
