Answer:
The speed of the cart decreases
Explanation:
The track is frictionless, so we can consider the cart as isolated system (no external forces acting on it): therefore, the momentum of the cart is conserved
where m is the mass and v the speed of the cart.
When it starts raining, some water falls into the cart: this means that the mass of the cart, m, increases. But we said that the momentum, p, must remain constant: in order for that to happen, this means that the speed of the cart, v, must decrease (because the relationship is an inverse relationship, so if m increases, v must decrease).

Hey there!
Flammability is a chemical property. It doesn't change based on what state of matter the object is in.
Let me know if this helps :)
Answer:
All of the above
Explanation:
To ensure the ball go to where we expected it go
Malleable
Malleability
is a property of matter, that’s specializes in metals, in which these metals
can be bended, twisted or formed into a thinner sheets, and not being able to
shatter to pieces instead it can be formed into a new shape. Unlike the other
three, take for instance hardness. If a hard object such as wood for example
when used with an axe it breaks and it is lead to smithereens. Flammable like
is when applied to fire can dramatically explode when hit it obviously breaks.
Action force is your weight pushing down on the chair. The reaction force is the force exerted by the chair that pushes up on your body and is equal to your weight. objects have inertia.
