Answer:
<h2>0.14 kg</h2>
Explanation:
The mass of the ball can be found by using the formula
v is the velocity
k is the kinetic energy
From the question we have
We have the final answer as
<h3>0.14 kg</h3>
Hope this helps you
Accuracy is the closeness of a measurement to the true value. Precision is the closeness of agreement among a set of results.
Suppose you read a refrigerator thermometer five times and get the Celsius readings 39.0, 39.3, 39.0, 39.1, and 39.0.
The average temperature is 39.1 °C. Your readings are <em>precise</em> because most of the readings are within 0.1 °C of the average.
However, if the actual refrigerator is 37.0 °C, your readings are <em>not accurate</em> because they are off by about 2°C.
If you use a thermocouple and get an average reading of 37.00, 37.03, 37.00, 37.01,and 37.00, your readings are both <em>accurate</em> and <em>more precise</em> than those from the refrigerator thermometer.
Answer:
1. True.
2. False.
3. True.
Explanation:
1. Mass is simply defined as the quantity of matter present in a body. This means that mass gives us an idea of the amount of matter present in any object or body.
Therefore, the answer to the question is True.
2. Weight of an object is simply defined as the gravitational pull of the earth on an object. This implies that location of the object will greatly influence it's weight as the gravitational pull will varies from place to place. Hence, the weight of the object will differ as the location of the object changes.
Therefore, the answer to the question is False.
3. As defined above mass is the amount of matter present in an object.
The mass of an abject is constant irrespective of the location of the object.
Therefore, the answer to the question is True.
Answer:
