Answer:
Explanation:
The y component of the force is 100 sinØ . But given that y component is 30N
so 100 sinØ = 30
sinØ = 0.3
Ø = 17.5°.
X component of force = 100 cosØ
= 100 cos17.5
= 95.35 N .
Y component of force = 30 N .
Angle Ø = 17.5°.
Answer:
They were produced by stars that lived and died before our solar system was born.
Explanation:
According to what it's understood today, all elements heavier than hydrogen (including helium and excluding some that were created in laboratories) are created through nuclear fusion in the core of stars.
They start fusing hydrogen into helium, then as the star grows older helium is fused into beryllium and so on for all the periodic table.
So as far as science understands it today it's a literal truth that we are made of stars. (as almost everything else)
Answer: I looked it up and it says something about the waves traveling in a solid but I don’t know if that’s correct.
Answer:
5 sq. root 3
Explanation:
theta= 60°
=> u sin theta = 10 × sin 60
= 10× sq. root 3/2
= 5 sq. root 3
The outer planets have a high gravity due to their large size
