Answer:
The net force and the acceleration on the falling skydiver is upward
Explanation:
An upward net force on a downward falling object would cause that object to slow down. the skydiver this slows down. As the speed decreases, the amount of air resistance also decreases until once more the skydiver reaches a terminal velocity.
For a solid to change its state of matter into liquid, energy is applied or heat is being used. With a solid, particles are very compacted and still, with a liquid they are not as compacted but can still take a defined shape.
Answer:
There are actually three, Kepler's laws that is, of planetary motion: 1) every planet's orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet's orbital period is proportional to the cube of the semi-major axis of its

Answer:
d. Every second, the truck’s velocity increases by 3 km/h to the south.
Explanation:
Acelleration can be defined as change of velocity over change of time.
That's why if we say: "A truck accelerates 3 km/h/s south."
We are saying that the acceleration of the truck variate 3Km/h wich is velocity of the truck, and it variates every second and also its direction is south.
