Assess It! Question #2: Which of the following statements about the Law
2 answers:
Answer:
Statement B is the only true statement
"<em>Decreasing the mass of an object increases its acceleration while force is constant.</em>"
Explanation:
Recall that Newton's 2nd Law states:
F = m * a
Therefore, if the force (F) is constant, and the mass (m) decreases, the acceleration (a) of the object must increase.
This agrees with the statement labeled as B: "<em>Decreasing the mass of an object increases its acceleration while force is constant.</em>"

<u>Answer</u>
D. 1,500 m/s
<u>Explanation</u>
the wave equation states that,
V = λf
Where V ⇒ Velocity
λ ⇒ wavelength
f ⇒ Frequency
F = 1/T
Where T ⇒ period
F = 1/0.006
= 166.667
∴ V = 9 × 166.667
= 1,500 m/s
