Answer:
D) all of the above
Explanation:
All of the given choices are correct definition of what weight of a substance implies.
Weight is the vertical force on a body due to the gravitational attraction or pull.
Weight = mass x acceleration due to gravity
Mass of a body is directly proportional to its weight and so also is the gravity.
Mass is the amount of matter within a substance.
Weight is the force of gravity exerted by a body on another or a surface.
The reason why the weight of a body changes from place to place is mainly due to the gravitational pull
Answer:
Average speed = (total distance covered) / (time to cover the distance)
You only need the first and last points from the table.
First point: Position=0, Time=0
Last point: Position= 16.34, Time = 2.34 hours
Total distance covered = 16.34 (miles ? km ?)
Time to cover the distance = 2.34 hours
Average speed = (16.34 miles) / (2.34 hours)
Average speed = 6.983 mile/hour
Explanation:
Answer:
has a radius of 2439 km (1524 mi), and the metallic iron-nickel core is believed to make up about 75% of this distance. Measurements of the planet's magnetic field made by Mariner 10 as it flew by the planet indicates that this core is likely to be hot and fluid.
Um... This is not exactly physics...(Although, this school of thought is most likely Moral Relativism.)
