Answer:
the cognitive abilities of an individual to learn from experience to reason well, and to cope effectively with the demands of daily living
Explanation:
Yes that can be understood by a simple example
Suppose two people are in exam
- A difficult and logical question came
- The person can use his cognitive abilities faster can solve that
Answer:
When a converging lens is placed under water then its focal length increases.
Explanation:
When any lens, be it converging or diverging is immersed into water then the speed of light before and after the refraction through the lens has less speed and due to less difference in speed it shows less deviations as a result the focal length is increased for the lenses.
Lesser the difference between the refractive index of the medium and the lens glass greater becomes its focal length.
<u>The focal length of the lens immersed in a medium is given by:</u>
where:
refractive index of the glass material with resp. to air
refractive index of the medium with resp. to air
radii of curvature of the two surfaces of the lens
Final angular speed
ω = v / r = 2.20m/s / ½*35.0m = 0.126 rad/s
and so prior to reaching that final speed
the angular acceleration
α = Δω / Δt = 0.126rad/s / 15.0s = 0.00838 rad/s² ◄
and the tangential acceleration
a = Δv / Δt = 2.20m/s / 15.0s = 0.147 m/s² ◄
OR
a = αr = 0.00838rad/s² * ½*35.0m = 0.147 m/s² ◄
Answer: F = Gm·M/R²
Explanation: you need to calculate gravitational force.
M = mass of Earth
G = gravitational constant 6.67·10^-11 Nm²/ kg²
R= 6378 km ( also double this)
And mass of satellite is 1000 kg
