Answer
Given,
Periscope uses 45-45-90 prisms with total internal reflection adjacent to 45°.
refractive index of water, n_a = 1.33
refractive index of glass, n_g = 1.52
When the light enters the water, water will act as a lens and when we see the object from the periscope the object shown is farther than the usual distance.
The accurate about the planet’s climate system is the wind
because heating near the equator blows the wind to drive the convection cells in the atmosphere, and the friction created by the rotation of the spherical planet in the atmosphere causes the wind to appear to bend left or right across the surface of the planet. ..
The climate system is a highly complex global system consisting of five major components: the atmosphere, the ocean, the cryosphere (cryosphere), the land surface, the biosphere, and the interactions between them.
Solar energy drives the climate by heating the surface of the earth unevenly. Ice also reflects incoming sunlight, further cooling the poles. Temperature differences move the ocean and atmosphere as they work together to disperse heat throughout the globe.

V = fλ
v/f = λ
λ = v/f = (1.45 x 10³) / 230
λ = 6.304 m
Wavelength is ≈ 6.304 m
Answer: 10m/s^2
Explanation:
Force acting on couch = 200N
Mass of couch = 20 kg
Acceleration of the couch = ?
Recall that force is the product of the mass of an object by the acceleration by which it moves.
i.e Force = Mass x Acceleration
200N = 20kg x Acceleration
Acceleration = 200N/20kg
Acceleration = 10m/s^2
Thus, the acceleration of the couch is 10m/s^2
