Answer:
The branches of physics are;
- Classical physics
- Modern physics
- Nuclear physics
- Atomic physics
- Geophysics
- Biophysics
Explanation:
Physics is a branch of science that studies nature, properties of matter and energy. The subjects in study are; mechanics, light, heat, light, sound, electricity, properties of atoms and magnetism.
The common branches are;
- Thermodynamics which that studies heat, how it is transferred and effects
- Sound that studies production, properties and application of sound waves
- Light that deals with properties,pysical aspects and objects that utilize light
- Electricity and magnetism that studies charges, their effects and relation with magnetism
- Classical physics that studies laws of motion and gravity
- Modern physics that study theory of relativity and quantum mechanics
Answer:
A total = 0.04 m²
Explanation:
given data
mass = 75 kg
area = 0.05 m²
pressure = 3 kPa
solution
pressure when human walking on ground
p = .................1
p =
p = 14.715 kPa
and
when walk on snow got extra pressure
P total = p + p (extra) ................2
P total = 14.715 + 3 = 17.715 kPa
and
total pressure is also
p total =
A total =
A total = 0.04 m²
Answer:Its an electric train so there is no smoke so no where.
