It's velocity is not constant as direction is changing.
We know, velocity is speed with direction, so if direction is changing, velocity can't be constant, doesn't matter that speed is constant.
Hope this helps!
Answer:
Explanation:
When the block is displaced by x units
F= spring force
two springs are connected parallel
Writing Newtons second law, F = ma
a= x" ( differentiating x w.r.t time twice)
this the standard form of equation of oscillation spring mass system
This is the differential equation, x'' means that double differentiation of x , i.e, x'' is acceleration
since, Period 
therefore,
Answer:
15.8 N
Explanation:
The component in a given direction is the magnitude of the applied force, multiplied by the cosine of the angle between its application and the direction of interest.
The horizontal component is ...
(20 N)cos(38°) ≈ 15.8 N
1). A radio EM wave has a frequency somewhere between 10 KHz and 300 GHz, whereas a visible light EM wave has a frequency somewhere between 428,000 GHz and 790,000 GHz.
2). A radio EM wave has a wavelength somewhere between 1 mm and 30 km, whereas a visible light EM wave has a wavelength somewhere between 380-700 nanometers.
