Answer: m∠P ≈ 46,42°
because using the law of sines in ΔPQR
=> sin 75°/ 4 = sin P/3
so ur friend is wrong due to confusion between edges
+) we have: sin 75°/4 = sin P/3
=> sin P = sin 75°/4 . 3 = (3√6 + 3√2)/16
=> m∠P ≈ 46,42°

Answer:
Explanation:
Since the object is under a circular motion, according to Newton's second law, when the object is at the top of the circle we have:
Where 
is the centripetal force and is given by:
Replacing and solving for T:
Rotation. The Earth rotates around the sun on it’s axis. Depending how far north or south you live, and the angle of the sun at different times of year gives you the amount of daylight or darkness you will receive. So the length of day or night depends on how much the sun is able to reach the spot on a round object such as the planet Earth.
Answer:
C
Explanation:
Static electricity is what makes your hair stand up when you rub a balloon against it or gives you a shock from your doorknob. In static electricity, electrons are moved around mechanically (i.e. by someone rubbing two things together).
