Answer:
The mechanical advantage is 0.25
This mechanical advantage shows that the force at which the deodorant sprays is the quarter of the applied effort, and hence the efficiency of your finger as a machine is 25%.
Explanation:
Given;
output force, F₂ = 15 N
input force, F₁ = 60 N
Mechanical advantage also known as force ratio is defined as the ratio of the output force (load) to the ratio of input force (effort).
This shows that the force at which the deodorant sprays is the quarter of the applied effort, and hence the efficiency of your finger as a machine is 25%.
Answer and Explanation:
Using Javascript:
test7_11_13(num){
If(num%7===0||num%11===0||num%13===0){
Console.log("yes it is a multiple of 7,11 or 13");
}
else{
Console.log("It is not a multiple of any of the numbers");
}
function(num){
var makeString= num.toString();
var splitString= makeString.split("");
var makeNumber= splitString.map(Number());
var New_number= makeNumber.reduce(function(a, b) {
return a+b};,0)
}
If(New_number%2===0){
Console.log("it's an even number");
}
else{
Console.log("it's an odd number")
}
If(num%2===0||num%3===0||num%5===0||num%7===0||num%11===0){
console.log("it's not a prime number");
}
else{
console.log("it's a prime number");
}
}
From the above we have used javascript if..else statements to test the conditions for each question and output the answer to the console using console.log(). In the last part for prime number, you could also choose to use else if statements(if,else if, else if) to test the value of the num parameter and output if it's a prime number.
