Answer:
The force of static friction acting on the luggage is, Fₓ = 180.32 N
Explanation:
Given data,
The mass of the luggage, m = 23 kg
You pulled the luggage with a force of, F = 77 N
The coefficient of static friction of luggage and floor, μₓ = 0.8
The formula for static frictional force is,
Fₓ = μₓ · η
Where,
η - normal force acting on the luggage 'mg'
Substituting the values in the above equation,
Fₓ = 0.8 x 23 x 9.8
= 180.32 N
Hence, the minimum force require to pull the luggage is, Fₓ = 180.32 N
Answer:
Solution A is 1 x 10⁵ times more acidic than solution B
Explanation:
The pH scale is a logarithmic scale used to express the acidity or basicity of a solution.
The values are written from 1 - 14 with 1 being the most acidic and 14 a basic solution.
Each interval is ten folds more concentrated than the next because it is a logarithmic scale.
Since the pH of A = 3.4
pH of B = 8.4
The difference = 8.4 - 3.4 = 5.0
So, Solution A is 1 x 10⁵ times more acidic than solution B
C is the correct option
As momentum = (mass) (velocity)
P=mv
So the object having greater mass has less velocity and the object having smaller mass will move faster. But product of mass and velocity is same to each other.
Well,
The sun's energy is produced mainly in the core, which has sufficient temperature to initiate nuclear fusion.
