I would have to say hockey it's like soccer... but with ice
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.
Bruh just multiply 9.5 by 140 because if he runs for 140 seconds and runs 9.5 meters per second then he runs 9 meters per second
The answer to your question is Protons!
<span>A.) He used an experiment with gold foil to prove that an atom had a
positive nucleus in the middle and was surrounded by negative electrons.
Hope this helps!
