What determines the velocity of an object? Its acceleration at a given point in time Its weight in a given location Its displace
tensa zangetsu [6.8K]

We can confirm that the velocity of an object is determined by the displacement of the object over a period of time.

<h3>How do we know that displacement and time determine velocity?</h3>

We know this by analyzing the scientific formulas created to measure the velocity of an object. The formula for this is \frac{d}{t} , meaning displacement over a period of time. Since option 3 described this equation perfectly, we can say that this is the correct option.

Therefore, we can confirm that the velocity of an object is determined by the displacement of the object over a period of time.

Answer:

I hope this will help you and Please mark me as Brilliant

Explanation:

Approximately 2 mL of Solution A (on the left) is added to a sample of Solution B (on the right) with a dropping pipet. If a precipitate forms, the resulting precipitate is suspended in the mixture. The mixture is then stirred with a glass stirring rod and the precipitate is allowed to settle for about a minute.

Solution A: 0.5 M sodium hydroxide, colorless

Solution B: 0.2 M nickel(II) nitrate, green

Precipitate: light green

Ni(NO3)2(aq) + 2 NaOH(aq) —> Ni(OH)2(s) + 2 NaNO3(aq)
