Answer: 50 m
Consider the figure below: Let O be the starting reference point. The boy runs northwards 125 m and then 75 m southwards.
Displacement is the shortest path traveled from the reference point. Distance is the total path length traveled. Hence, the distance would be 125 +75 =200 m but the displacement would be .
Answer:
Density of water is 1 g/cm³.
Explanation:
Given:
Mass of given volume of water is,
Volume of the given amount of water is,
We know that, density of a quantity is given as the ratio of its mass to that of its volume.
Here, in order to calculate density of water, we need to divide the mass of water by its volume. Therefore,
Plug in 10 g for 'm', 10 cm³ for 'V and solve for density. This gives,
Therefore, the density of water of mass 10 g and volume 10 cm³ is 1 g/cm³.
