the heat produced in a circle depends upon resistance current and time if error in measuring these quantities are 1% 2% and 1% respectively the measured heat is

6%

Explanation:

Equation ; Q = I^2 RT

(Q is the heat; I - current; R - resistance ;T - time)

∆Q/Q = 2×∆I/I + ∆R/R + ∆T/T

= 2× 2 + 1 + 1

= 4 + 1 + 1

= 6%

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
