2 kg
Explanation:
Remember:
F = m * a re-arrange to
F/a = m substitute in the given values
10 / 5 = 2 kg
Answer:
12 units
Explanation:
Original F = C q1q2/r^2 now change the parameters
New F = C 1/3 q1 2 q2 / (2r)^2
= 2/12 C q1q2/r^2 <=======the new force is 1/6 of original
1/6 * 72 = 12 units
Answer:
Tuning the keys.
Explanation:
<em>"Guitar strings are tuned (tightened and loosened) using their tuning keys. </em><em>Applying too much tension to a string tightly can raise it to the pitch of the next note, while loosening it can easily lower it the same amount.</em><em> Increasing the tension raises the pitch. The length of a string is also important."</em>
