Answer:
a) 121 km
b) 74°
Explanation:
To start with, we assume that there exist two components, the East and the North. We'd be representing the East, by "e" and the North, by "n"
Now we start with the
First vector:
east1 = 232 cos 30 = 201
north1 = 232 sin 30 = 116
Now, that of the second vector will be
east 2 = - 168
north2 = 0
Next, we add the two together and get
East components
201 - 168 = 33 east
North components
116 + 0 = 116
Therefore, the magnitude has to be
magnitude = √(33² + 116²)
Magnitude = √14545
Magnitude = 121
tanθ = 116/33
Tanθ = 3.51
θ = tan^-1 3.51
θ = 74° North East
Answer:
Inelastic collisions actually do conserve energy, but the loss of energy to heat and mechanical vibration is hard to calculate so the math equating energy before and energy after is hard to balance.
Answer:
i believe there is something wrong in your question
Explanation:
False. What actually determines the properties of elements are the electrons, or aka valence electrons. They are used to bond, which determines its properties.
Answer:
No, the apparent weight will be different.
Explanation:
Although the mass is still the same, the apparent weight will be different. This is because of the centripetal acceleration caused by the Earth's rotation. At the poles, there is no centripetal acceleration. The closer you get to the equator, the larger the centripetal acceleration becomes, and the lower the apparent weight becomes.
