Actually they are closer...this is because <span>the nearside mirror is convex to increase its field of view. The idea is to make sure you are aware of any vehicles that might be sneaking up on your "inside" before you move back into the "slow lane".</span>

Answer:
a) T = (2,375 ± 0.008) s
, b) When comparing this interval with the experimental value we see that it is within the possible theoretical values.
Explanation:
a) The period of a simple pendulum is
T = 2π √ L / g
Let's calculate
T = 2π √1.40 / 9.8
T = 2.3748 s
The uncertainty of the period is
ΔT = dT / dL ΔL
ΔT = 2π ½ √g/L 1/g ΔL
ΔT = π/g √g/L ΔL
ΔT = π/9.8 √9.8/1.4 0.01
ΔT = 0.008 s
The result for the period is
T = (2,375 ± 0.008) s
b) the experimental measure was T = 2.39 s ± 0.01 s
The theoretical value is comprised in a range of [2,367, 2,387] when we approximate this measure according to the significant figures the interval remains [2,37, 2,39].
When comparing this interval with the experimental value we see that it is within the possible theoretical values.
Explanation:
the impact cull ball stop,bit transfer all of it
momentum and kinetic energy to the another ball resunting in the hit ball rolling with the initial speed of the cue ball .
1) temperature
2) pressure
3) concentration
4) surface area
5) the presence of a catalyst
