This is a graph of a marble traveling across a smooth surface. what is the average speed of this marble?

v = 1.5 m/s

Explanation:

The attached figure shows a distance time graph. The motion of marble is uniform. It covers equal distance in equal interval of time. The average speed of the car is calculated by finding its slope in d-t graph.

From the attached figure,

Slope of the graph is given by :

v = 1.5 m/s

So, the average speed of this marble is 1.5 m/s.

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
