Answer:
I think it's D!!
cuz protons are in the atoms
The water cycle starts with evaporation. It is a process where water at the surface turns into water vapors. Water absorbs heat energy from the sun and turns into vapors. Water bodies like the oceans, the seas, the lakes, and the river bodies are the main source of evaporation. Through evaporation water moves from hydrosphere to atmosphere.
Answer: 339.148N
Explanation:
Data
Time (t) = 47s
U = 0m/s
V = 9.5m/s
Mass of B = 540kg
Frictional force on B = 230N
Both boats are connected so if A moves, B moves too.
Acceleration of boat A =?
Using equation of motion,
V = u + at
9.5 = 0 + a*47
a = 9.5 / 47
a = 0.2021 m/s²
The force required to accelerate boat B since it's the same force moving both boats =?
F = Mass * acceleration
F = 540 * 0.2021 = 109.14N
A frictional force of 230N exists on boat B
Total force (Tension) = frictional force + normal force = (109.15 + 230)N = 339.148N
For any pure substance, the boiling point and melting point will always remain sharp or distinct. This is because the substance has uniform properties all throughout. Hope this answers the question. Have a nice day. Feel free to ask more questions.
