Answer:
False
Explanation:
The steel ball and the wooden ball do not have the same force acting on them because their masses are different. But, they have the same acceleration which is the acceleration due to gravity g = 9.8 m/s².
Using the equation of motion under freefall, s = ut +1/2gt². Since u = 0,
s = 1/2gt² ⇒ t = √(2s/g)
Since. s = height is the same for both objects, they land at the same time neglecting air resistance.
Answer:
The charge resides on the outer surface = C
Explanation:
Surface area of cell
Separation between two plate
Dielectric constant
Potential difference
The capacitance of parallel plate capacitor in free space is given by,
Where permittivity of free space =
The Capacitance of capacitor is increase by times when it placed in dielectric medium.
And we know that,
So charge on the outer surface is given by,
Our eyes are detectors which are designed to detect visible light waves (or visible radiation). ... The electromagnetic spectrum includes gamma rays, X-rays, ultraviolet, visible, infrared, microwaves, and radio waves. The only difference between these different types of radiation is their wavelength or frequency.
