Answer:
0
Explanation:
The displacement is zero since it goes in a full circle and ends up where it started.
2 electrons. electrons are negative, protons are positive. if it is electrically neutral, there must b the same Amt of them so they can cancel out
It would be "resonance" that is occurring that causes the nonvibrating tuning fork
<span>to begin to vibrate. Specifically the resonance of the sound waves that are traveling through air. </span>
Answer: -5 m/s
Explanation:
First find the net force by summing up the forces:
-10N + 5N = -5N
Use Newton's Second Law of motion to solve for the acceleration:
F = ma
-5N = 1kg(a)
a = -5 m/s^2
Use the first kinematic equation to solve for the final velocity:
Vf = Vi + at
Vf = 0 + (-5)(1)
Vf = -5 m/s
In this item, there needs to be a basis as to how many significant numbers can be present in a certain figure. If the answer 327.66 m/s is to be expressed as a 3 significant figures only, the answer would have to be 328. What was done here is to simply round up the units digit of the number since the decimal place (tenths) digit has a value of greater than 4.
The answer to this item is therefore letter B.
