If an astronomer claims to have discovered an object with a very eccentric orbit, what best describes the orbital trajectory of the object?

Explanation:

It would look like  a squashed oval.

An celestial object's orbital eccentricity is a dimensionless factor which specifies the extent through which its trajectory  about another body detracts from a complete circle. A measure of 0 is a circular orbit, numbers between 0 and 1 generate an elliptic orbit, a parabolic escaping orbit and a hyperbola for value greater than 1. For values far greater than one  it looks like  a squashed oval.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

we need to know the time interval during which the force acts. impulse of force = momentum change
