Answer:
It Is violet
Explanation:
It has the shortest wavelengths and the shorter the wavelengths the higher the frequency.
The description refers to the styloid process or tuberosity. This styloid process is seen in the 5th metatarsal and this area shows the fifth metatarsal's growth plate. This bone is being attached by strong tendon known as the <span>Peroneus brevis tendon.</span>
Answer with Explanation:
Mass of block=1.1 kg
Th force applied on block is given by
F(x)=
Initial position of the block=x=0
Initial velocity of block=
a.We have to find the kinetic energy of the block when it passes through x=2.0 m.
Initial kinetic energy=
Work energy theorem:

Where
Final kinetic energy
=Initial kinetic energy

Substitute the values then we get

Because work done=

![K_f=[2.4x-\frac{x^3}{3}]^{2}_{0}](https://tex.z-dn.net/?f=K_f%3D%5B2.4x-%5Cfrac%7Bx%5E3%7D%7B3%7D%5D%5E%7B2%7D_%7B0%7D)

Hence, the kinetic energy of the block as it passes thorough x=2 m=2.13 J
b.Kinetic energy =
When the kinetic energy is maximum then 





Substitute x=

Substitute x=

Hence, the kinetic energy is maximum at x=
Again by work energy theorem , the maximum kinetic energy of the block between x=0 and x=2.0 m is given by

![k_f=[2.4x-\frac{x^3}{3}]^{\sqrt{2.4}}_{0}](https://tex.z-dn.net/?f=k_f%3D%5B2.4x-%5Cfrac%7Bx%5E3%7D%7B3%7D%5D%5E%7B%5Csqrt%7B2.4%7D%7D_%7B0%7D)

Hence, the maximum energy of the block between x=0 and x=2 m=2.48 J
Answer:
2.91 x 10¹² sec
Explanation:
d = distance of nearest star, Proxima Centauri = 4.3 ly = 4.3 x 9.46 x 10¹⁵ m
v = speed of new horizon probe = 14 km/hr = 14000 m/s
t = time taken for the new horizon probe to reach nearest star, Proxima Centauri = ?
Using the equation
d = v t
Inserting the values given
4.3 x 9.46 x 10¹⁵ = (14000) t
t = 2.91 x 10¹² sec
