Answer:
When the spectral lines are absorption lines, the effect is called inverse Zeeman effect.
Answer:
*he force to climb a plane inlcinado with constant velicad is equal to the cosine of the weight of the body
*he force to climb a plane inlcinado with constant velicad is equal to the cosine of the weight of the body
Explanation:
When a car is going up an inclined plane with constant speed, we can solve the problem using the translational equilibrium equation
Let's locate one axis parallel to the plane and the other perpendicular
F - W x = 0
F = W cos tea
therefore wes ee that the force to climb a plane inlcinado with constant velicad is equal to the cosine of the weight of the body
Work is defined by
W = F. l
in this case the force and displacement are constant
W = F L
where L is the length of the plane
W = mgL cos tes
we see that the work is equal to the cosine of the force times the distance on the plane
I'd say the atmosphere plays a role in all of these but if I had to choose one it would be D
Answer:
Explanation:
When I hear "transformation of energy from one form to another", I think of the system exchanging energy with its surroundings. A transformation of energy simply means the system contains a different type of energy than it previously did. One example I can give is a ball. A ball at the top of a hill has a maximum potential energy. If given the chance to roll, it will go to a minimum state of potential. This will convert all of the potential energy into pure kinetic energy, once it reaches the bottom of the hill of course.
