Your gonna have to divide 143 into 9 and then that will be your answer
D: how close a measurement is to an accepted value for the measurement.
Answer: Option C. Is the correct answer.
Explanation: Wave length is the distance between the crest of each wave. If you were to decrease it you would be decreasing the distance between each wave therefore making it smaller and closer together as option C. shows.
Answer:
330Ns
Explanation:
Given parameters:
Mass of the box = 5kg
Initial velocity = 0m/s
Force applied = 15N
Time = 22s
Unknown:
Impulse = ?
Final momentum = ?
Solution:
The impulse of the box can be determined using the expression below:
Impulse = Force x time
Impulse = 15 x 22 = 330Ns
The final momentum is the same as this impulse
The impulse and the final momentum is 330Ns
One consequence of Newton's third law of motion is that all actions have equal and opposite reactions. <em>(C)</em>
In fact, that's pretty much what the law itself says in so many words.
