If your mass is 50 kg (you weigh 110 pounds), and the mass of the refrigerator
is 100 kg (it weighs 220 pounds), and you're standing so that the center of
the frig and the center of you are 1 meter apart (about 3 feet), then the force
of gravity between you and the frig is about 0.0000012 ounce. That's why.
Answer:
PE = (|accepted value – experimental value| \ accepted value) x 100%
Explanation:
Answer:
Minimum percentage error = 20%
Explanation:
The zero error of the screw gauge is
(5*0.5)/50 = 0.05 mm
Least count on the circular scale is 0.5/50 = 0.01 mm
Equivalent circular scale reading = 0.01 * 25 = 0.25 mm
Reading on the main scale = 2 * 0.5 = 1 mm
Actual measurement = 1 +0.25-0.05 = 1.20 mm
The minimum percentage error in the reading will be (1.20 mm -1.00 mm)/1*100 = 20%
