Answer:

mark the brainiest if you like the answer

Explanation:

Distance moved by effort is 20m,that of load is 0.8m

VR= L

d

E

d

VR= 0.8

20

VR=25

the load is 10,000N and effort=500N

MA= effort

d

load

d

MA= 500

10000

MA=20

The error in his measurement of time is δT=0.01 s and he measures the depth of the well to be L=20m. Take the acceleration due to gravity g=10ms-2 and the velocity of sound is 300ms-1 .Then the fractional error in the measurement,...
