Moving the body to do something
The first one: A. Decreases one half of the original weight.
The second one: D. a change in the objects linear velocity.
Answer:Even things that appear to be at rest move.
When we describe the motion of one object with
respect to another, we say that the object is moving
relative to the other object.
• A book that is at rest, relative to the table it lies
on, is moving at about 30 kilometers per second
relative to the sun.
• The book moves even faster relative to the center
of our galaxy.
Explanation:
Answer:
<h3>6.80kg, 6.70kg and 6.90kg.</h3>
Explanation:
To get the set of measurements that best represents accuracy if the true value is 6.80 kg, we will find the mean of the set of numbers and chech which is equal to 6.80kg
According to the set of data 6.8kg, 6.7kg and 6.9kg
Mean = sum of the number/sa mple size
Sum of the numbers = 6.8+6.7+6.9 = 20.4
sample size = 3
Mean of the set of measurement = 20.4/3
Mean of the set of measurement is 6.80kg
Since the answer is 6.8kg, hence set of measurements that best represents accuracy are 6.80kg, 6.70kg and 6.90kg.
