The values of measurement of a physical quantity in five trial were found to be 1.51, 1.53, 1.53, 1.52, and 1.54. Then (1) Average absolute error is 0.01 (2) Relative error is 0.01. (3) Percentage error is 0.01% (4) Percentage erroris 1% (multiple answers correct)

Answer»

lute Error = +or- 0.004

Relative Error = ∆ā/ā = 0.02/7.63 = 0.003

Percentage error = ∆ā/ā × 100 = 0.3% (approximately)

(1), (2), (3) are close to the answers

Explanation:

Given,

a a - ā = ∆a

1.51 1.51 - 1.53 = -0.02

1.53 1.53 - 1.53 = 0

1.53 1.53 - 1.53 = 0

1.52 1.52 - 1.53 = -0.01

1.54 1.54 - 1.53 = 0.01

∑a= 7.63

ā = ∑a/n = 7.63/5 = 1.526 which approximately 1.53

∆ā = ∑ |∆ā| / n = | -0.02 + 0 + 0 - 0.01 + 0.01 | / 5

=0.02 / 5 = which is approximately equal to 0.004

Relative Error = ∆ā/ā = 0.02/7.63 = 0.00262....

Approximately = 0.003

Percentage error = ∆ā/ā × 100 = 0.3% (approximately)

These are the answers for the given VALUES.

So, In the objective OPTIONS given, the values closest can be selected since the EXACT value is not matching with the options.

So the Answer for your Question may be

(1), (2), (3) which are close to the answers WHEREAS (4) is no where near the answer.

Concept of free fall for class 11​

Answer» ONG>Answer:

In Newtonian physics: free fall is any MOTION of a body where gravity is the only force acting upon it.

in this case V= u -gt. and S =ut +1/2 gt^2

all other forces like air resistance, buoyancy etc are Absent! it's an IDEAL case.

a Paratrooper whose Parachute did not open YET , experience nearly a Freefall. Newtons Apple fell free and must have hit Newton on head with Velocity nearly 3.6 m/sec if the height from which it fell was 2 meters.

In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it.
