Answer:
Thermal expansion causes the bar to expand in length (also, thermal contraction causes the bar to shrink). Having the meter measured in this way allows for consistency and can be easily converted.
Explanation:
Answer:
a = d p / dt = 23 m / s², The direction is the direction of the force
Explanation:
Newton's second law can be written in the form
F = dp / dt
How the body is initially at rest
F = m a
a = F /m
a = 6 /0.260
a = 23 m / s²
a = d p / dt = 23 m / s²
The direction is the direction of the force
The further away from the mid-ocean ridge, the older the rocks are on the ocean floor. Therefore, the ocean floor feature that would contain the newest rocks would be the mid-ocean ridge.
Answer:
In a truss bridge, two long - usually straight members known as chords - form the top and bottom; they are connected by a web of vertical posts and diagonals. The bridge is supported at the ends by abutments and sometimes in the middle by piers.
