Answer:
The answer to the question lies in the character of God. God is either finite or infinite. If God is finite and limited, then God could make a rock He could not lift. If God is unlimited in power, then He could create a rock of any size and weight and still be able to lift it.
Explanation:
Answer: Taking into account sound is a wave, we can use the information of the displacement (generally given as a graph) to find the wavelength and frequency, then we can calculate the speed with the formula of the speed of a wave.
Explanation:
If we have the displacement graph of the sound wave, we can find its amplitude, its wavelength and period (which is the inverse of frequency).
Now, if we additionally have the frequency as data, we can use the equation of the speed of a wave:
Where:
is the speed of the sound wave
is the wavelength
is the frequency
First, light passes through the cornea. It bends the light inward. The light then passes through the pupil. After entering the eye through the pupil, the light passes through the lens. It focuses the light to create an image on the retina. It consists of light receptor cells called rods and cones. The rods and cones send nerve impulses about the image to the brain through the optic nerve. The visual cortex of the brain receives and interprets the information and tells you what you are seeing
By Newton second law of motion
Force = Mass*Acceleration
=> 20N = 5kg*Acceleration
So Acceleration = 20/5 ( Also Acceleration= Force/Mass)
So 20/5 = 4
So Acceleration = 4m/s^2
