Answer:
The distance moved is 82 m.
The displacement is 18 m to the south.
Explanation:
The distance is a measure of the total length traveled along the path, while the displacement only takes into account the length between the starting position (departure) and final position (arrival). That is, distance refers to how much space an object travels during its movement, being the amount moved, while displacement refers to the distance and direction of the final position with respect to the initial position of an object.
So, the distance being the sum of the distances traveled, you get:
18 m + 22 m + 14 m + 28 m= 82 m
<u><em>The distance moved is 82 m.</em></u>
You know that the tennis ball moves 18 meters to the north, then 22 meters to the south, then 14 meters to the north, and finally 28 meters to the south. Then the tennis ball moves:
- northward: 18 m + 14 m= 32 m
- to the south: 22 m + 28 m= 50 m
Calculating the displacement as the difference between the final position and the initial position, you get:
displacement= 50 m - 32 m= 18 m
<u><em>
The displacement is 18 m to the south.</em></u>
Answer:
0.0018
Explanation:
Given that,
Mass of a solid, m = 450 kg
Volume, V = 250 cm³ = 0.00025 m³
The density of solid is given by :
Density = mass/volume
So,
The density of water is 1000 kg/cm³.
Relative density = density of solid/density of water
So, the relative density of the solid is 0.0018

<span><u>Answer </u>
Metals are better conductors that metalloids and non-metals.
<u>Explanations
</u>
Metals have free electrons that facilitate the conductivity of heat. When a metal is heated at one end the electrons at that end gain kinetic energy and a carry heat energy from one end to the other.
Metalloids on the other hand lies between a metal and a non-metal. They would conduct heat but not as effective as metals.
For non-metal, they do not have free electron and so they do not conduct heat at all. </span><span>
