It would be B, the weather patterns outside.
The magnitude of the displacement of the car from the starting point to halfway around the track is 256 m.
Answer:
Explanation:
Since the race track is a circular track, the distance for one lap will be equal to the circumference of the circular track. And the circumference will be equal to the circumference of the circle.
Since the radius of the track is given as 200 m, then the circumference of the circular track will be
Circumference = 2πr = 2 × 3.14 × 200
So the circumference of the circular track = 1256 m.
So the starting point or position of the track is considered as zero and if the car has traveled half way means, the car has covered half of the circumference of the track.
As the circumference = 1256 m, then half of the circumference of the circle = 1256/2 = 256 m.
So the displacement is the measure of difference between the final position and initial position. As here the initial position is zero and the final position is the halfway around the track which is equal to 256 m.
Then Displacement = Final-Initial = 256-0= 256 m.
So the magnitude of the displacement of the car from the starting point to halfway around the track is 256 m.
Answer:
A. Mg+2
Explanation:
im not sure, but since it lost two electrons which have a negative charge it gained two charge.
Answer:
High Potential Difference
Explanation:
Lightning is a type of Electrical Discharge and for any electrical discharge to happen we require a high potential difference between two areas in space.
In case of lightning this potential difference can be formed between 2 clouds, between a cloud and the ground or two different areas in the same cloud.
So during lightning this potential difference causes different type of lightning due to electrification followed by charge separation and hence aggregation of charge is specific areas of clouds.
