If You Have Two Moons That Have the Same Radius

question 67

Multiple Choice

If you have two moons that have the same radius, but Moon A is denser and has 2 times the mass of Moon B, how do their escape velocities from their respective surfaces compare?

• A) Moon A has an escape velocity that is 1.4 times larger than Moon B.
• B) Moon A has an escape velocity that is 1.4 times smaller than Moon B.
• C) Moon A has an escape velocity that is 2 times smaller than Moon B.
• D) Moon A has an escape velocity that is 2 times larger than Moon B.
• E) Because gravity affects all masses the same, the escape velocities are the same.

Definitions:

Trachea

The main airway (windpipe) leading from the larynx to the lungs, allowing the passage of air for respiration.

Pharynx

The pharynx is a muscular tube that connects the nasal and oral cavities to the esophagus and larynx, playing a key role in the respiratory and digestive systems.

Nasal Conchae

These are long, narrow, curled shelves of bone that protrude into the nasal cavity, increasing its surface area.

Epiglottis

A leaf-shaped flap of cartilage located behind the tongue, at the top of the larynx, which prevents food from entering the airways during swallowing.
