Answer:
please find the attachment to this question.
Explanation:
In this question, we represent the 100N in the North-East direction, but first, we define the vector representation:
It is generally represented through arrows, whose length and direction reflect the magnitude and direction of the arrow points. In this, both size and direction are necessary because the magnitude of a vector would be a number that can be compared to one vector.

Some commonly used techniques might be distillation and magnetism.
Distillation is basically a method of separating liquid mixture by basically boiling and condensing the different liquids. Since liquids don't have the same boiling points. one will evaporate first, and the other liquid or liquds will remaim.
Magnetism is a method of separating solid mixtures. One or some solids will get atracted to the magnet and the others will remain. Note that this only works if one of the solids has a magnetical property.
Hope it helped,
Happy homework/ study/ exam!
Answer:
a) Find the work done by the resistive force during the roundtrip.
W=-30kJ
b) Is the resistive force a conservative force? explain.
The resistive force is not a conservative force since the work done during the round trip is not zero
Explanation:
The worf done on object y a constant force F is given by:
W= (F cos ∅)S
Where S is the displacement and ∅ is the angle between the force and the displacement.
The displacement of the bicycle during each part of the trip is s=5000m and teh magnitude of teh resistance force is F=3.0N
∅1=180° he angle between the displacement and the force
W1=W2
W1 = (3.0 cos180) 5000m
W1=-15.O kJ
W=W1+W2
W=-30kJ
The resistive force is not a conservative force since the work done during the round trip is not zero
Answer:
45degres
Explanation:
A projectile travels the farthest when it is launched at an angle of 45 degrees.
It means the experiment can be reproduced again and again with close results to that of the first experiment. please give brainliest?
