I believe the answer is 25*3.5 I apologize if this information is incorrect.<span />
The 6 common phase changes are evaporation, condensation, freezing, Melting, sublimation & deposition. Hope this helps.
Answer:
a = 6.7 m/s²
Explanation:
The formula to apply here is :
Mass * acceleration = Tension -weight
m*a = Ft -mg -----where m is mass of block, a is acceleration , Ft is force due to tension.
Given in the question that ;
Mass of block = 3 kg
Ft = 50 N
g= 10
m*a = Ft -mg
3*a = 50-30
3a= 20
a= 20/3
a= 6.7 m/s²
