Answer:
Increases
Explanation:
From Newton's second law:
F = ma
If F stays the same and m decreases, then a increases.
Therefore, the magnitude of the train's acceleration increases (the acceleration becomes more negative).
Stars are not really planets because they are far, far away from our solar system.

Answer:
The magnitude of the force the garbage exerts on the floor of the service elevator is 12 N
Explanation:
Given;
mass of the garbage, m = 10.0 kg
acceleration of the elevator, a = 1.2 m/s²
The magnitude of the force the garbage exerts on the floor of the service elevator is given by;
F = ma
F = 10 x 1.2
F = 12 N
Therefore, the magnitude of the force the garbage exerts on the floor of the service elevator is 12 N
Answer:
437.5Kjoules
Explanation:
K.E=half multiply by mass multiply by square of velocity
=437.5Kjoules
Réponse/explication:
La réaction qui produit de l'hydrogène et de l'oxygène à partir d'eau est endothermique. Certains changements de phase comme la vaporisation, la fusion ou la sublimation et la plupart des réactions de décomposition chimique sont endothermiques.
