Wewaii [24]2 years ago
3 0

Answer:

the acceleration is 3 k/h/s

Explanation:

The formula for acceleration is Δv/t, so change in velocity divided by time.

The original velocity is 15 kph, and the final velocity is 30 kph. Therefore, the change in velocity is 15 kph. 15/5=3 k/h/s

To present his data on the <span>solubility of three different salts in water at 22°C, bar graph should be used since there are different salts and the only variable is the type of salt used. Line graph and scatter plot use two coordinates or variables and is common to comparing data using the same sample while using histogram to find out data distribution is irrelevant.</span>
