ololo11 [35]

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.

A 4-kilogram cat is resting on top of a bookshelf that is 3 meters high. What is the cat’s gravitational potential energy relati
hichkok12 [17]
The answer is 117.6 J

The potential energy of the object is actually its stored energy:

<span>E = m · g · h
E - the potential energy of the object,
m - the mass of the object,
g - acceleration due to gravity,
h - the height of the object.

m = 4 kg
g = 9.8 m/s</span>²
h = 3 m

E = 4 * 9.8 * 3 = 117.6 J
