south = -(north)
Displacement = (4 km north) + (2 km south) + (5 km north) + (5 km south)
Displacement = (4 km north) - (2 km north) + (5 km north) - (5 km north)
Displacement = (4 - 2 + 5 - 5) km north
<u>Displacement = 2 km north </u>
Answer:
<em>W=700 Joule</em>
Explanation:
<u>Physics Work
</u>
Is the dot product of the force vector by the displacement vector
When both the force and the displacements are pointed in the same direction, the formula reduces to its scalar version
The weightlifter is applying a net force of 350 N to lift the weights a distance of 2 m, thus the net work done is
For a given wave in a given medium, if the frequency doubles,
the wavelength becomes 50% shorter.
That is, it becomes half as long as it was originally.

Explanation:
The measuring sensitivity of liquid-in-glass thermometers increases with the amount of liquid in the thermometer. The more liquid there is, the more liquid will expand and rise in the glass tube. For this reason, liquid thermometers have a reservoir to increase the amount of liquid in the thermometer.
Answer:
1. A glass of water at 80°C because the more heat it will recieve, the more temperature increases. Heat is a sort of energy so the more it is heated, the more energy the water will recieve. So in comparison to 20°C, 80°C has more energy in it because it has a higher temperature.
2. An aluminium can at 30°C because the more heat it will recieve, the more temperature increases. Heat is a sort of energy so the more it is heated, the more energy the aluminium will recieve. So in comparison to 20°C, 30°C has more energy in it because it has a higher temperature.
