This means that the horizontal force is 750sin(25°). To be able to move the truck, force applied must be greater than static friction, which equals to its coefficient (0.77) x normal contact force (= weight)
Hence, 750sin(25°) = 0.77mg. m = 750sin(25°)/(0.77g)
Answer:
Average speed = 24 km/h
Explanation:
<u>Given the following data;</u>
Uniform speed A = 30 km/h
Uniform speed B = 20 km/h
To find the average speed;
Mathematically, the average speed of an object is given by the formula;
..... equation 1
Total time = TA + TB




Total distance = x + x
Total distance = 2x
Substituting the values into equation 1;



<em>Average speed = 24 km/h</em>
Depends on the elasticity and density of the medium through what it is traveling <span> </span>
Explanation:
Given that,
Charge 1, 
Charge 2, 
Distance between charges, r = 0.0209 m
1. The electric force is given by :


F = -492.95 N
2. Distance between two identical charges, 
Electric force is given by :




Hence, this is the required solution.
Answer:
a) CI^- ⇒ CI2 + 2e^-
b) 4.2 * 10^9 amperes
c) 1.4 * 10^10 watts
Explanation:
Given data:
Annual production of C12 = 45 millions tons per year
Typical plant operational percentage = 90%
Operating voltage of a cell = 3.4 v
A) Half-cell reaction for oxidation chloride to form chlorine
CI^- ⇒ CI2 + 2e^-
B) Calculate the total current worldwide needed to generate the global supply of CI 2
Total current =
=
= 4.2 * 10^9 amperes
Q = charge , t = time
C ) Calculate electrical power need to produce global supply of chlorine using electrolysis
P = V*I
= 3.4 * 4.2 * 10^9
= 1.4 * 10^10 watts
