"watt" means "Joule of energy per second"
"60 watts" means "60 Joules per second"
(60 joules per second) x (5 seconds) = <em>300 Joules of energy</em>
To determine the reaction order with respect to crystal violet and determine the rate constant and half life for the reaction: [CV+ + OH– Þ CVOH]
Answer:

Explanation:
Time elapsed on Earth
= 12 years
Time elapsed on board the ship
= 9.2 years
now r=
= 12/9.2= 1.3043


v= 
therefore distance L= 
putting value we get
=
=
=

Answer: 2.541884 meters
Explain:
Formula: s = 0.5 * g * t^2
Time of fall (t) is 0.72 while the gravitational acceleration rate is (9.80665m/s^2).
