Answer:
Explanation:
Given
On Earth
On the moon
Required
The astronaut's mass on the moon
The mass of an object do not change base on location
So, if the mass of the astronaut is 80kg on earth, it will be 80 kg on the moon.
Hence:
Answer:
15
Explanation:
The if else state is used for checking the condition and if the condition is TRUE and program can execute the statement within the if else.
Initially input_value is 5
then the if statement check the condition 5>5, condition FALSE because 5==5
it not less than 5.
then program move to else if and check condition 5>2, condition TRUE.
then, input_value = 5 + 10=15 execute and update the value to 15.
After that, program terminate the if else statement.
Therefore, the answer is 15.
Answer:
15.7 ; 78.5
Explanation:
Mechanical advantage of a screw = Circumference / pitch
Circumference = pi × d
Where :
pi = 3.142, D = diameter
Therefore ;
Circumference = 3.142 × (1/4) = 0.785 in
Pitch = 1/TPI
TPI (thread per inch) = 20
Pitch = 1/ 20 = 0.05
Mechanical advantage = 0.785 / 0.05 = 15.7
Resistance force if effort force is 5lb
Mechanical advantage = Fr / Fe
Fe = effort force, Fr = resistance force
15.7 = Fr / 5
Fr = 15.7 × 5 = 78.5 lbs
