Question

select the correct answers. which of these are commonly used units of measure for the speed of a moving object? select 2 choice(s) m km m/s² g/ml m/s km/h

Explanation:

Speed is defined as the distance traveled per unit of time. The formula for speed is \(v=\frac{d}{t}\), where \(v\) is speed, \(d\) is distance, and \(t\) is time.

• \(m\) (meter) is a unit of distance, not speed.
• \(km\) (kilometer) is a unit of distance, not speed.
• \(m/s^{2}\) is a unit of acceleration (\(a = \frac{\Delta v}{\Delta t}\), where \(\Delta v\) is change in velocity and \(\Delta t\) is change in time).
• \(g/ml\) is a unit of density (\(

ho=\frac{m}{V}\), where \(m\) is mass and \(V\) is volume).

• \(m/s\) (meters per second) is a unit of speed as it represents distance (\(m\)) divided by time (\(s\)).
• \(km/h\) (kilometers per hour) is also a unit of speed as it represents distance (\(km\)) divided by time (\(h\)).

Answer:

\(m/s\), \(km/h\)
