Answer:
: Rocket weight on earth
: Rocket weight on moon
Explanation:
Conceptual analysis
Weight is the force with which a body is attracted due to the action of gravity and is calculated using the following formula:
W = m × g Formula (1)
W: weight
m: mass
g: acceleration due to gravity
The mass of a body on the moon is equal to the mass of a body on the earth
The acceleration due to gravity on a body is different on the moon and on the earth
Equivalences
1 slug = 14.59 kg

To calculate the weight of the rocket on the moon and on earth we replace the data in formula (1):
: Rocket weight on earth
: Rocket weight on moon

Answer:
The extent to which it would stretch is 
Explanation:
From the question we are told that
The initial length is 
The area is 
The Young modulus of the steel is 
The tension is 
The Young modulus is mathematically represented as
Where 
is the stress which is mathematically represented as
Substituting values
And e is the strain which is mathematically represented as
Where 
The extension of the steel string
Substituting these into the equation above
Substituting values
