D. The ocean water runs off earth’s surface
Answer:
I am 98% sure that the answers are B and A
Explanation:
Answer:
Explanation:
Initial charge,
After conduction, charge on the body becomes,
We need to find the number of electrons gained by this charged body.
Net charge,
Let n be the number of electrons gained by this charged body. So,
So, electrons gained by this charged body.
The speed of an object can be determined from the distance vs time graph.
You know that speed = distance/time
in the graph, distance/time = slope of the curve.
So SPEED IS GIVEN BY THE SLOPE of the curve in the graph.
● If the distance vs time curve is a straight line, parallel to time axis(x-axis), slope is 0. That means speed is 0. So the object is at rest.
● If the distance vs time curve is a straight line, with some non-zero slope; That means speed is nonzero and constant. So the object is in uniform motion.
● If the distance vs time curve is a curved, the slope is changing. That means speed is changing. So the object is in an accelerated motion.
