Elements to the left tend to form positive ions is the right answer mark me brainlist
That's a simple description of how <em>ultrasound</em> works.
Um tbh i failed school so hahah
Answer:
7.66 m/s²
Explanation:
The following data were obtained from the question:
Initial velocity (u) = 0 mph
Final velocity (v) = 60 mph
Time (t) = 3.5 s
Acceleration (a) =.?
Next, we shall convert mile per hour (mph) to metre per second (m/s). This can be obtained as follow:
Recall:
1 mph = 0.447 m/s
Initial velocity (u) = 0 mph
Initial velocity (u) = 0 × 0.447 = 0 m/s
Final velocity (v) = 60 mph
Final velocity (v) = 60 × 0.447 = 26.82 m/s.
Finally, we shall determine the acceleration of Rihanna as follow:
Initial velocity (u) = 0 m/s
Final velocity (v) = 26.82 m/s.
Time (t) = 3.5 s
Acceleration (a) =.?
a = (v – u) /t
a = (26.82 – 0) / 3.5
a = 26.82 / 3.5
a = 7.66 m/s²
Thus, the acceleration of Rihanna is 7.66 m/s²
