Answer:

Option A is correct.

The hydraulic pressure in a closed hydraulic brake system is constant.

Explanation:

The hydraulic brake system works on the principle of pressure transmission. It is termed a closed hydraulic brake system when there is no leakage of fluid all through the setup. The transmission works on the basis of Pascal's law for pressure and it explains that pressure applied to a fluid is transmitted undiminished to every part of the fluid.

The force applied on the brake pedals by the driver at the controlling end of the hydraulic system is transmitted by the pushrod on the piston(s) in the master cylinder.

This causes fluid from the brake fluid reservoir to flow into a pressure chamber. This in turn causes an increase in the pressure of the entire hydraulic system, forcing fluid through the hydraulic lines toward the caliper(s) where it then acts upon the caliper piston(s).

The force applied on the brakes pedal, F₁,

is applied on the cross sectional Area of the master piston, A₁ and this is transmitted in terms of pressure by the fluid (with no loss in pressure, that is, constant pressure, if the hydraulic braking system is especially a closed one) through the callipers to the calliper(s) pistons.

Hope this Helps!!!

Answer:

A. Is constant

Explanation:

This is in accordance with pascal's law of pressure that states the hydraulic pressure in a fluid is transmitted undiminished to every portion of the fluid.

2. Write a Java program that generates a new string by concatenating the reversed substrings of even indexes and odd indexes sep
Nana76 [90]

Answer:

  1. public class Main {
  2.    public static void main(String[] args) {
  3.        String testString = "abscacd";
  4.        String evenStr = "";
  5.        String oddStr = "";
  6.        for(int i=testString.length() - 1; i >= 0; i--){
  7.            if(i % 2 == 0){
  8.                evenStr += testString.charAt(i);
  9.            }
  10.            else{
  11.                oddStr += testString.charAt(i);
  12.            }
  13.        }
  14.        System.out.println(evenStr + oddStr);
  15.    }
  16. }

Explanation:

Firstly, let declare a variable testString to hold an input string "abscacd" (Line 1).

Next create another two String variable, evenStr and oddStr and initialize them with empty string (Line 5-6). These two variables will be used to hold the string at even index and odd index, respectively.

Next, we create a for loop that traverse the characters of the input string from the back by setting initial position index i to  testString.length() - 1  (Line 8). Within the for-loop, create if and else block to check if the current index, i is divisible by 2, (i % 2 == 0), use the current i to get the character of the testString and join it with evenStr. Otherwise, join it with oddStr (Line 10 -14).

At last, we print the concatenated evenStr and oddStr (Line 18).

GREYUIT [131]

Answer:

a) the two-way concrete joist framing system

Explanation:

A waffle slab is also known as ribbed slab, it is a slab which as waffle like appearance with holes beneath. It is adopted in construction projects that has long length, length more than 12m. The waffle slab is rigid, therefore it is used in building that needs minimal vibration.

Arlecino [84]

Answer:

The correct answer is At least two of the stimulants will have different effects on the mean time spent awake.

Explanation:

The null hypothesis exposed leads to consider an alternative hypothesis that differs from the behavior of the 4 stimulants. In this case it is related to the effects on patients, since in practice at least one will present differences compared to the others, influencing the sleep time of consumers.
