Answer:
Explanation:
Displacement can be displayed as a vector, this because it has magnitud and direction. Because of this, we can think John's Resultant Displacement as the join of this two vectors.
The First Vector is from the 249 Km Marker to the 141 Km Marker, which give us a Vector with a Magnitude equals to 108 Km.
The Second Vector goes from 141 Km Marker to the 174 Km Marker, which give us a Vector with a Magnitude equals to 33 Km.
However is important to know the direction for each Vector, we notice that John was traveling on one direction and then he returned. This makes our Vector to have a different direction, and this means difference signs. Difference signs means substraction. So, the Third Vector will be:
Third Vector = 108 Km - 33 Km
Third Vector = 75 Km
The moon is closer to the earth than the sun
What do you need help with?
Answer:
65 miles
Explanation:
The distance travelled till 150 miles is
260 - 150 = 90
But as he walks back although his distance increase his displacement from initial point decrease.
Distance moved from 150 mile post to 175 mile post is
175 - 150 = 25
As he walks backwards in second time in consideration with first time to calculate the displacement we need to substract 90 from 25,
So displacement is 65 miles
Answer:
For a positive point charge, the lines radiate <u>outwards</u>, while for a negative point charge, the lines converge<u> inwards.</u>
Explanation:
A single point charges produces an electric field which has a radial shape.The sign of a charge determines the the direction of the field. In Positive charge have the direction of field is out of the charge and for negative charge, the direction of field is towards the charge.This behavior is in relation to how a positive test charge will experience in a field.
