Answer:
Weight at the surface of Jupiter's moon Io is 8.13 N .
Explanation:
Given :
Acceleration due to gravity at the surface of Jupiter's moon is 
.
Weight of watermelon in earth , 
.
Acceleration due to gravity at the surface of earth is 
.
We know , weight is given by :
Therefore , mass at the surface of Jupiter's moon Io is :
Hence , this is the required solution .
Answer:
Against but it really depends on the situation
Answer:
its The rolling friction is greater than the force of the car’s weight against the hill.
and A force was required to start the car rolling.
Explanation:
Answer: The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons. The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.
Explanation:
Acceleration = Change in velocity / time taken
= (5 - 15) / 2
= -5 ms^-2
