Answer:

(C) by increasing its mass

Explanation: Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.

I NEED HELP ASAP, If you help me I’ll give you Brainlist [Calorimetry and specific heat lab]
Lyrx [107]

Answer:

Explanation:

I gave this formula as

What you should get - what you got

---------------------------------------------------   * 100

What you should get

Suppose you are talking about the specific heat of copper and you did a lab and did it fairly well and the specific heat came out to be 0.33

That's what you got, 0.33

What you should get is 0.35 according to the table you've given us.

% error = 0.35 - 0.33

                -------------- * 100

                      0.35

% error = 0.02 * 100/ 0.35

% error = 2/0.35

% error = 5.71

Now here is the really hard part. You have to decide what a positive error is and what a negative error.

A positive error using this formula means you are too low.

A Negative error means that you are too high, just the opposite of what you might think.

A student measures the mass of 40 mL of a liquid 3 times. They obtain mass readings of 28.5 g,
algol [13]

It can be said that the measurements of the students are precise but not accurate.

<h3>What is accuracy and precision?</h3>

Accuracy is the degree of conformity of a measure to a true or standard value while precision is the ability of a measurement to be reproduced consistently.

Simply put, measurements are said to be accurate when they are close to a true or standard value but are said to be precise when they are close to one another.

According to this question, a student measures the mass of 40 mL of a liquid 3 times and obtained the following mass readings: 28.5g, 28.4g and 28.2g.

Based on the measurement, the measured data are precise because they are close to one another but are not accurate because they are not near the standard value of 37.9g.
