Answer:
1.553 M^2s^-1
Explanation:
Now let us consider experiments 1,2,3.
In experiment 1 and 2, the concentration of NO is doubled and the initial rate of reaction is quadrupled.
0.575/0.144 = 4
So;
2^2 =4
In experiment 2 and 3
The concentration of reaction of H2 is doubled and the rate of reaction is doubled.
0.575/0.287 = 2
2^1 =2
So we can now write;
Rate =k[NO]^2 [H2]^1
Taking up the first reaction;
0.144 =k [0.475]^2 [0.411]
k = 0.144/ [0.475]^2 [0.411]
k = 1.553 M^2s^-1
The magnitude of the force causing this acceleration is 15 N
<u>Explanation:</u>
we know that
F=ma: According to the newton's second law
F - force acting on the object
m - mass of the object
a - acceleration
Newton's second law states that acceleration depends on force acting on the object and mass of the object.
Force is directly proportional to acceleration and mass is inversely proportional to acceleration.
here,
m = 5 kg
a = 3 m/s2

Power is defined in a mathematical expression as P = F x v where F is in N and v is in m/s. From the given equation, the v = d/t which is v = 10/ 6, then substituting the answer to the power formula W = 54 N (10/6 m/s) = 90 Watts.
