In order to see what forces are acting upon an object in every direction.
Because the object is still made of the same material
Density is not affected by the weight and shape of an object its affected by how concentrated the atoms are in a given volume
Mechanical waves transfer energy by including vibration in the propagation medium electromagnetic waves do not require a medium for propagation but still transfer energy by having an electric and magnetic field propagate perpendicular to one another. Hope this helps:)
Hey I need a pic then I'll answer in the comments. If no pic then if a red petal is directly facing a side, then it will be facing the adjacent clockwise side.
Answer:
a) 12.4 km
b) 8.8 km
Explanation:
a) Distance is the total space covered by an object in its entire journey.
So, distance = 6.9+1.8+3.7 = 12.4 km
Distance travelled by the whale is 12.4 km
b) Displacement is the minimum distance between the final and initial point of the journey.
Let us take direction towards East as positive and direction towards west positive.
So, Displacement is given by
6.9-1.8+3.7 = 8.8 km
The displacement of the whale is 8.8 km
