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
Answer:
Δ S = -50 J
Explanation:
given,
Temperature, T = 500 K
Heat dissipates, Q = 25.0 kJ
Q = 25000 J
change in entropy, ΔS = ?
using equation of entropy
Δ S = -50 J
negative sign is used because heat is lost in the surrounding.
Hence, Change in entropy is equal to -50 J
