Answer:
0.1m
Explanation:
k = 64N/m
Ep = 0.32J
x = ?
Ep = 1/2 * kx²
make x the subject of the formula
x² = 2Ep/k
x = √(2Ep/k)
x = √(0.64/64)
x = √0.01
x = 0.1m
Answer:
v = √(5² + 4²) = √41 ≈ 6.4 m/s
Explanation:
The third choice best describes reliability: <span>Editorial blogs are considered an unreliable source because the author may not have a science background.
The first statement is illogical, just because the public can access information does not make it unreliable. The second also is incorrect, if charities receive money from the public, they may have incentive to publish popular theories to get more support, so they are unreliable. The fourth is incorrect, because we don't have any background on who the authors are.
