If `I_1 = (12.0 +- 0.1)` cm and `I_2 = (8.5 +- 0.5)cm` find `(l_1 +l_2) and (l_1 +l_2)` with proper error limits.

If L_(1) = (2.02 +- 0.01)m and L_(2) = (1.02 +- 0.01)m then L_(1) + 2L_(2) is (in m)

If L_(1) = (3.03 +- 0.02)m and L_(2) = (2.01 +- 0.02)m then L_(1) + 2L_(2) in (in m )

If L_1 = 2.02 m pm 0.01 m , L_2 = 1.02 m pm 0.01 m , determine L_1 + 2L_2

If L_1 = 2.02 m pm 0.01 m , L_2 = 1.02 m pm 0.01 m , determine L_1 + 2L_2

The lengths of the two pieces of wire are l_1 =(35.2 +- 0.1) cm and l_2 = (47.4 +- 0.2) cm. what is the total length of wire with error limits ?

If l_(1) = (10.0 pm 0.1) cm and l_(2) = (9.0 pm 0.1) cm , find the their sum , difference and error in each .

If l_(1) = (10.0 pm 0.1) cm and l_(2) = (9.0 pm 0.1) cm , find the their sum , difference and error in each .

If L = 2.06 cm +- 0.02 cm B = 1.11 cm +- 0.03 cm What are (L + B) and (L - B) equal to ?
