Answer:
Wavelength
Explanation:
Wavelength is the distance between two corresponding consecutive phases of a waveform. It is usually represented by λ in the mathematical expressions.
A continuous propagating wave repeats its wavelength over the distance.
A wave has crest and trough with respect to time and space.
Wave is defined as a disturbance of any parameter repeated in a cyclic manner over the given time.
Answer:
Velocity
v= i + 2 j
Acceleration
a= 2 j
Explanation:
Given that
r(t) = t i + t² j + 3 k
We know that
Velocity v given as
v= dr/dt
dr/dt= i + 2 t j +0
v= i + 2 t j
At t= 1
v= i + 2 x 1 j
v= i + 2 j
Acceleration ,a
a= dv/dt
v= i + 2 t j
dv/dt= 2 j
a= 2 j
