The answer is
a symmetrical molecule.
a person running a car parked in a driveway
Explanation:
A person running a car parked in a driveway is an example of translational kinetic energy.
Translational motion is the movement of body along a straight path.
Translational kinetic energy refers to the energy of a body moving along a straight path.
- It is function of the mass and velocity of the moving body.
- The motion of train on its track is an example of this form of energy
- A fired bullet, falling object all experience translational kinetic energy.

Answer:
T or True
Explanation:
The intertidal zone is any place or area where the ocean meets land, also known as shorelines or coastlines. The ecosystems found in these area experience lots of changes. Just think, whenever the tides are low, the area is exposed to air and the sun, but during low tide, it is submerged underwater.
Answer : The correct option is, (B) 
Solution :
According to the Graham's law, the rate of effusion of gas is inversely proportional to the square root of the molar mass of gas.

or,
..........(1)
where,
= rate of effusion of unknown gas = 
= rate of effusion of oxygen gas = 
= molar mass of unknown gas = ?
= molar mass of oxygen gas = 32 g/mole
Now put all the given values in the above formula 1, we get:


The unknown gas could be carbon dioxide
that has approximately 44 g/mole of molar mass.
Thus, the unknown gas could be carbon dioxide
