Ford was the first person to receive this patent.
Answer
I think most see black and white.
Explanation:
Image distance, v = -17 cm (-ve for virtual image)
Radius of curvature of concave mirror, R = 39 cm
Focal length, f = -19.5 cm (-ve for a concave mirror)
(a) Using mirror's formula as :


u = 132.6 cm
So, the object is placed 132.6 cm in front of the mirror.
(b) Magnification of the mirror, 

m = -0.128
Hence, this is the required solution.
The total mechanical energy of the ball is the sum of its potential energy U and its kinetic energy K, therefore:

so, the total mechanical energy of the basketball is 118 J.
Answer:

Explanation:
Given,
Number of turns, N = 64
angular velocity, ω = 377 rad/s
Magnetic field, B = 0.050 T
Area, a = 0.01 m²
maximum output voltage = ?
We know,



The maximum output voltage is equal to 12.064 V.
