Answer: The shortest wavelength of light is the ultraviolet ray, which is the highest in Energy.
Explanation:
- In the electromagnetic spectrum, we find the visible spectrum (roughly between 400 - 700 nm wavelength) between the ultraviolet (with wavelengths lower than visible) and the infrared (with wavelengths higher than visible, used by fiber optics in telecommunications).
- As there is a relationship inversely proportional between wavelength and frequency (which is the inverse of the period), if the wavelength is shorter, the frequency is higher.
- If the frequency is higher, this means that the light can change more quickly, which is a consequence of having more energy.
- This is clearly showed in quantum theory by this expression for the energy of one photon: E = hν, where h is the Planck Constant, and ν is the frequency of the photon.
Answer:
Most of the frogs have webbed feet which helps them swim. The thin skin between the toes helps them to push through the water. The frog's feet is webbed ,So they can easily swim.. The skin between toes are flexible soo they can freely push and pull it
Explanation:
The friction force has a 2 N force.
The static friction coefficient that exists between the project and the surface should be multiplied to provide the friction force. When the surface is thought of as horizontal, the normal force should be equal to the weight of the block and should also be directed in the opposite direction.
the friction force is therefore
= 0.5*N = 0.5* (10)
= 5
The friction force is greater than the force acting on the block, which is why there is no movement of the object even though it should be the reverse. Furthermore, the actual force needs to be equal.
The friction force here should therefore be 2N.

A 2.0-N force acts horizontally on a 10-N block that is initially at rest on a horizontal surface. The coefficient of static friction between the block and the surface is 0.50. What is the magnitude of the frictional force that acts on the block?
Answer: energy transfer. or, kinetic energy.
Explanation:
when something collides with another, it transfers kinetic energy to the other it collided with, making it move.
Answer:
W = 0.012 J
Explanation:
For this exercise let's use Hooke's law to find the spring constant
F = K Δx
K = F / Δx
K = 3 / (0.16 - 0.11)
K = 60 N / m
Work is defined by
W = F. x = F x cos θ
in this case the force and the displacement go in the same direction therefore the angle is zero and the cosine is equal to 1
W = ∫ F dx
W = k ∫ x dx
we integrate
W = k x² / 2
W = ½ k x²
let's calculate
W = ½ 60 (0.19 -0.17)²
W = 0.012 J
