Answer:30 V
Explanation:
Electric Field Strength is 50 N/C due to east
Voltage measured at a point P is 80 V
Let us assume point P is at a distance of x m
therefore
x=1.6 m
Now Potential directly 1 m west of P
therefore distance is 1.6 -1 =0.6 m
Thus potential is
Answer:
Sarah is right
Explanation:
This is an exercise that differentiates between scalars and vectors.
A scalar is a number, instead a vector is a number that represents the module in addition to direction and sense.
In this case, the distance (scalar) traveled is a number, which is why it is worth 1500m, but the displacement is a vector and since the point where it leaves is the same point where the vector's modulus arrives is zero, so the DISPLACEMENT VECTOR is zero
consequently Sarah is right

Answer: b. The flow of air is neither toward the warm air mass nor toward the cold air mass.
A stationary front forms between two air masses. A stationary front results when the warm front or cold front air stops moving. This occurs due to the fact that warm front and cold front air masses being opposite to each other but neither of them are able to repel the other. This affects the climatic conditions of the region. The weather is often cloudy along a stationary front and also supported with fall of rain and snow especially if the air in the front is cold with low atmospheric pressure.
<em>Therefore, along a stationary front the flow of air is neither toward the warm air mass nor toward the cold air mass.
