I have a strong hunch that if you read through pages 184 to 187 in the book,
you'll find each of these statements there, with no blank spaces.
1. negative
2. static
3. electrons
4. repel
5. attract
6. static
7. electric current
8. closed or complete
9. open
Answer:
x(t) = 0.077cos(6.455t)
Explanation:
If the spring can be stretched 0.2 m by a force of 50 N, then the spring constant is:
k = 50 / 0.2 = 250 N/m
The equation of simple harmonic motion is as the following:

where 
We also know that the initial velocity is 0.5 m/s, which is also the maximum speed at the equilibrium:


is the initial phase
Therefore, the position of the mass after t seconds is
x(t) = 0.077cos(6.455t)
Answer:
the answer is d
Explanation:
the more mass there is, the larger the gravitational pull is.
That completely depends on all sizes and all directions of all of the vectors that combined to produce the resultant one.
