The best answer is C) total mass of the team.
In tug of war, the mass of each team is a critical factor in determining which side wins. The team with greater mass will require greater force to move, and also is likely able to exert greater force on the other team due to the correlation between strength and mass.
Answer: 6.64 × 10^ -6 m
Explanation:
for a constructive interference;
ρ= 2πm
remember that we are looking for the seventh bright side fringe.
so, m=7
ρ=14π
We now have to find the phase different
ρ`=2πx/ρ - 2πx/ρ
p` is the wavelenght in the mica. x= width of the mica wavelength in the mica.
ρ= ρ/n.
n= refractive index.
The phase will now be
ρ`= 2πx/ρ - 2πx = 2πx(n-1)/ρ.
ρ= ρ`
14π = 2πx (n-1)/ ρ
we now solve for x; x = 7ρ/n-1
x = 7(550× 20^ 9)/ 1.58 - 1
= 6.64 × 10^-6
Answer : <u><em>Gravitational potential energy</em></u>
Explanation :
Gravitational potential is defined as the work done in moving an object from a fixed reference location to the location of object. This arises from the law of gravity and it acts against the gravity.
Mathematically, it is defined as potential energy (U) per unit mass (m).
i.e. 
The general form of Gravitational energy is
where, 
is gravitational constant
and 
are masses of interacting bodies
and 
is the distance between them.
Negative sign shows here that the system is bound.
When skeletal muscles contract, bones move. But how do muscles make your bones move? A voluntary muscle usually works across a joint. It is attached to both the bones on either side of the joint by strong cords called tendons. A tendon is a tough band of connective tissue that connects a muscle to a bone. Tendons are similar to ligaments, except that ligaments join bones to each other. Muscles move the body by contracting against the skeleton. When muscles contract, they get shorter. By contracting, muscles pull on bones and allow the body to move.
Hope this will you to understand the movement of the skeletal muscles
