Answer:
A hydraulic brake system
Explanation:
A wheel cylinder is a component of a hydraulic brake system. It is located in each wheel and is usually positioned at the top of the wheel, above the shoes. Its function is to exert force onto the shoes so as to bring them into contact with the drum and stop the vehicle with friction.

Explanation:
2 to 3 times
4 to 6 times
8 to 10 times
Answer:
8 to 10 times
Explanation:
For dry road
u= 15 mph ( 1 mph = 0.44 m/s)
u= 6.7 m/s
Let take coefficient of friction( μ) of dry road is 0.7
So the de acceleration a = μ g
a= 0.7 x 10 m/s ² ( g=10 m/s ²)
a= 7 m/s ²
We know that
v= u - a t
Final speed ,v=0
0 = 6.7 - 7 x t
t= 0.95 s
For snow road
μ = 0.4
de acceleration a = μ g
a = 0.4 x 10 = 4 m/s ²
u= 30 mph= 13.41 m/s
v= u - a t
Final speed ,v=0
0 = 30 - 4 x t'
t'=7.5 s
t'=7.8 t
We can say that it will take 8 to 10 times more time as compare to dry road for stopping the vehicle.

The value of x in the equation is 2.
Equation is defined as a mathematical expression that includes the sign "equal to" between two expressions with equal values. The three primary forms of linear equations are point-slope, standard, and slope-intercept. Systems of equations can be solved using one of three techniques: graphing, substitution, or elimination.
"Start Fraction one-half End Fraction left-parenthesis n minus four right-parenthesis minus three equals three minus left-parenthesis two plus three right-parenthesis" will have the algebraic expression
1/2 (n-4) - 3 = 3 - (2n + 3)
Add two to both sides (n-4) - 6 = 6 - 2(2n+3)
n - 4 - 6 = 6 - 4n - 6
Add comparable terms together: n + 4 n = 4 + 6
5n = 10
n = 10/5 = 2
∴ n = 2
Thus, the value of x in the equation is 2.
