Yes, considering lava accommodates rocks that have collapsed of cave walls it is heterogeneous.
Answer:
69.28N
Explanation:
horizontal force
Cos 60°= F(horizontal)/80N
If we cross multiply, we have
F(horizontal)= 80 cos 60°
= 40N
vertical forces
Sin 60°= F(vertical)/80N
If we cross multiply we have
F( vertical) = 80 sin 60°
= 69.28N
Therefore, the vertical force is 69.28N
