Answer:
b. able to travel through a vacuum.
Explanation:
The most distinguishing factor of an electromagnetic waves is that they are able to travel through a vacuum.
These waves do not require materials in a medium for propagation.
- Electromagnetic waves are formed by the propagation of the electric and magnetic fields.
- They vibrate at an angle of 90° .
- They are unlike like mechanical waves that requires that requires materials in medium for their propagation.
When given the exact same cross sectional area (as a constant), as the load increases, the stress will also increase as a consequence. The opposite holds true. When given a constant, non-changing cross sectional area, the stress decreases as the load decreases.
α=30°
F=20 N
Fh=F*cos(α)
Fv=F*cos(90-α)=F*sin(α) (vertical component of the force F)
Fv=20*0,5=10.00 N
Answer (C)
Answer:
The correct options are:
1) Protons
Explanation:
Brayons are composite subatomic particles which consist of odd number of valence quarks.Quarks are the fundamental particles in the nature that combine to form other particles such as neutrons and protons. In these composite subatomic particles strong nuclear forces dominate as compared to other fundamental forces in the nature.
A list of brayons includes (names are as represented in theory):
1) Proton's
2) Neutrons
3)Lambda
4) Sigma
5)Xi
6) Omega
7) Delta
Hence we find only proton is matching from the given options.
Answer:
a) The electric potential between the cylinders,
b) The electric field between the cylinders,
Explanation:
Voltage at the inner conductor, V₁ = 20 volts
Voltage at the outer conductor, V₂ = 100 volts
Change in potential,
The change in potential is given by the formula:
The electric field,
To get the electric potential at a certain point, L from the center:
The distance from the outer conductor to the center = b - L
The electric potential at L will be given by the equation:
