What will the value of the result variable be after the code segment below has been run.

int result ;

int number4 = 6,number11 = 9;

result = number4 + ++number11;

What will the value of the result variable be after the code segment below has been run.   

bool result ;  

int number3 = 17, number7 = 33;  

result = number3 > number7 ; 

What will the value of the solution variable be after the code segment below has been run.   

bool solution;

solution = number3 == number7;

The formula below describes Newton's second law of motion

Force = Mass x acceleration

Using the variables below Write one line of code that will calculate the acceleration of a object.

// Mass in Kg

float mass = 50.3;

// Froce in N

int force = 720; 

//acceleration

float accel;

//One line of code to calculate the acceleration of a object

What scale value would you use with analogWrite() to generate a average vlotage of 1V on PWM pin 10 ?

What will the value of the result variable be after the code segment below has been run.

(round to 4 decimal places)

float result ;  

int number3 = 253, number6 = 26;

float number11 = 3;  

result = ( number3 - number6 ) / number11 ;
