Which explanation of the solar system best fits the observations of the planets and how they orbit the sun? (points : 3) the gravity of a large, massive star passing the sun ripped off blobs of material from it that formed the planets.
the planets formed at the center of a collapsing spinning cloud of gas and dust.
the sun and planets formed from a collapsing spinning cloud of gas and dust.
a comet hit the sun and sent off fragments that became the planets.

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

The table below shows the acceleration of gravity on different bodies in the solar system. on which body would a 10 kg lamp has the most gravitational potential energy when lifted to a height of 2 m? a. earth b. mars c. neptune d. uranus
