Answer:
the weight of the object decreases when it is taken from the Earth to the Moon
Explanation:
The weight of an object is defined as the product of the mass of the object with the acceleration due to gravity of the Planet.

where,
W = weight of the object
m = mass of the object
g = acceleration due to gravity on the planet
The mass of an object remains constant everywhere in the universe. Therefore, the weight is directly proportional to the value of acceleration due to gravity.
The value of acceleration due to gravity on the Moon is lesser than its value on the Earth.
<u>Hence, the weight of the object decreases when it is taken from the Earth to the Moon </u>
It takes twice the force to produce the same acceleration in the 2kg rock.
Answer:
young's modulus
Explanation:
We have given length of tendon L= 13 cm =0.13 m
Change in length 
Force = 12.1 N
Average diameter d =8.8 mm
So 
Area 
Now stress 
Strain 
Now young's modulus
I will run 2 miles three times a week for 4 weeks.
