Answer:
k = 26319 N/m
Explanation:
given,
Period of bounce = 1.5 s
mass of the car = 1500 kg
four springs
to find the value of k

k = 26319 N/m
Now the value of force constant is k = 26319 N/m
It exchanges the cations or the anions of two ionic compounds.
The answer is The Heliocentric Theory was a theory that the planets revolved around the sun
Answer: Proposed that the sun was the center of the solar system.
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.
