B is a trough.
A trough is the opposite of a crest, in that it occurs at the maximum negative displacement of a wave.
In this problem, A would be the crest, C would be the wavelength, and D would be the amplitude.
Hope this helps!! :)
Answer:
σ = 4.1 MPa
Explanation:
Given that
m= 2.5 kg
v= 32 km.hr
v= 8.88 m/s
The kinetic energy of the mass ,KE
KE = mv²/2
KE = 2.5 x 8.88²/2
KE= 98.56 J -------1
The strain energy of the string
----2
KE= E
σ = 4.1 MPa
Answer:
- So, the force its N to the west.
Explanation:
The force on a charge q made by an electric field its
The electric charge of the electron its
.
Taking the unit vector pointing towards the east, the electric field will be:
.
So, the force will be:
So, the force its N to the west.
Explanation:
force, compel, coerce, constrain, oblige mean to make someone or something yield. force is the general term and implies the overcoming of resistance by the exertion of strength, power, or duress.
