will gain 1 electron in order to become stable.
force is mass * acceleration
so 2kg * 2m/s^2 = 4 N
Katarina is right. The explanation correct is because r is a distance and always positive, from she can see that when y is negative, sinθ is also negative.
<h3>What is the explanation for the above?</h3>
For every interval of odd multiple of π, to next even multiple of π, sinθ will be negative.
Mathematically,
Sin θ will be negative in
[(2n +1)π, (2n + 2)π]
Where, n is any integer (Positive or negative).
Hence, it is right to state that Katarina is right. The explanation correct is because r is a distance and always positive, from she can see that when y is negative, sinθ is also negative.

Full Question:
Dacia Asks Katarina To Tell Her What The Values Of Y Are That Can Make Sine Negative. Which Of Katarina's Replies Is Correct?
Answer:
b
Explanation:
n = m(g +a)
n= normal force (N)
m=mass (kg)
g=acceleration of gravity
a= acceleration of elevator
rearrange:
a= n/m - g
a= (810 N/73 kg) - 9.8 m/s ^2
a= 1.3 m/s ^2 up
and the acceleration is upwards bc her weight is less than the scale reading
Answer:
I believe this represents Newton's first law of motion. Any object in motion will continue to move until a force stops it, be it friction or a physical object.
