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:
Christmas is celebrated to remember the birth of Jesus Christ, who Christians believe is the Son of God.
Explanation:
Christmas is celebrated to remember the birth of Jesus Christ, who Christians believe is the Son of God. The name 'Christmas' comes from the Mass of Christ (or Jesus). A Mass service (which is sometimes called Communion or Eucharist) is where Christians remember that Jesus died for us and then came back to life.
Answer:
The correct answer is option C. pneumatic power transfer
Explanation:
Pneumatic power transfer is mostly used in food processing industry. The reason is because this pneumatic system usually consists of just air in the form of gas, which means that they will not face any poisonous leakages in the food production houses.
These systems rely heavily on the constant supply of compressed air which is then used to transmit and control the energy.
Answer:
The answer is " and 157.5 MPa".
Explanation:
In point A:
The strength of its products with both the grain dimension is linked to this problem. This formula also for grain diameter of 310 MPA is represented as its low yield point
Here y is MPa is low yield point, x is mm grain size, and k becomes proportionality constant.
Replacing the equation for each condition:
People can get yo = 275 MPa with both equations and k= 15.5 Mpa .
To substitute the answer,
In point b:
The equation is
equation is:
by putting the above value in the formula we get the value that is= 157.5 MPa
