Answer:
Explanation:
Coefficients of Friction
Objects in physical contact produce friction which usually manifests as thermal energy being dissipated in the surface where the objects are interacting. It's usually harder to start to move an object from rest, that keeps moving it at a constant speed on the same surface. That is why there are two different coefficients of friction: the static and the dynamic. As mentioned, the static coefficient 
is greater than the dynamic coefficient 
. The car is already moving and is attempting to stop. The coefficient of friction is defined as
Where Fr is the force of friction and N is the normal or the force the road pushes back up on the car. With the given data, we have
The coefficient of friction is dimensionless (doesn't have any units)
Answer:
2 blocks north 1 block east
Explanation math lol
you go 3 up, 2 left then one back down which puts you at 2,2 then she goes 3 east so its x = 1 y = 2
Answer: DNA polymerase and DNA ligase also are important in DNA replication. In addition to maintaining the integrity of DNA sequences by DNA repair, an accurate duplication of DNA is a prerequisite for all cell divisions.
Physical development , Cognitive Development , psychosocial development I think!
(a) The work done by the bird to raise the snake on the branch is equal to the product between the weight of the snake and the height of the branch above the ground:
where 
is the mass of the snake and 
is the height of the branch with respect to the ground. Substituting numbers into the equation, we find
(b) The work the bird did to raise its own centre of mass from the ground to the branch is equal to the product between the bird's weight and the height of the branch:
where 
is the mass of the bird. Substituting numbers into the equation, we find
