Answer:
a = 3 m/s^2
Explanation:
Vi = 10 m/s
Vf = 40 m/s
t = 10 s
Plug those values into the following equation:
Vf = Vi + at
40 = 10 + 10a
---> a = 3 m/s^2
Answer: 0.059M
Explanation: time.
t = 19minutes
t = 19 × 60 s
t = 140s
k = n/delta t
(where n is the ratio of change in concentration while delta t is the change in time)
k = n/dt = 6.30×10−3 s−1
6.30×10−3 s−1 = dc/140s
n = 6.30×10−3 s−1 × 140s
n = 882 ×10−3
= 0.882
Concentration of reactant used in forming a product in the reaction after 19 minutes =
n × concentration
0.882 × 0.5 = 0.441M
Reactant concentration
= (0.5 - 0.441)M
= 0.059M

Answer:
3.2 seconds
Explanation:
50 swings = 2 mins 40 secs
= 50 swings = 2 x 60 + 40 secs
= 50 swings = 160 secs
= 1 swing = 160 / 50 secs
= 1 swing -= 3.2 secs
