Answer:
The focal length is 15.549 cm
The power of the lens is 0.0643 D
Solution:
As per the question:
The near point is 50.0 cm
Distance of the glasses from the eyeball, d = 2.00 cm
The near point of a normal human eye is 25 cm
Now,
The image distance, v' = 50.0 - 2.00 = 48.0 cm
The object distance, u' = 25.0 - 2.00 = 23.0 cm
Now, using the Lens maker formula to calculate the focal length:
f = 15.549 cm
Now, the power of the lens in diopters is given by:

1500 kg is the mass of a truck if it produces a force of 9,000 N while accelerating at a rate of 6 m/s²
F=ma
m=F/a
m= 9,000 N / 6 m/s²
m=1500 kg
In physics, mass is used to convey inertia, a property common to all matter. In essence, it is the resistance of a mass of matter to altering its course or speed in response to the application of a force. The more mass a body has, the less of a change an applied force makes. Using Planck's constant, the kilogram, the ISU's unit of mass, is equivalent to 6.62607015 1034 joule seconds (SI). One kilogram is multiplied by one square meter per second to yield one joule. Since the second and the meter have already been defined in terms of other physical constants, the kilogram is determined by precise measurements of Planck's constant.
