Explanation:
The given data is as follows.
Concentration of caffeine = 2.97 mg/oz
Number of oz in a can = 12 oz
Therefore, the concentration of caffeine in one can is calculated as follows.
=
mg
= 35.64 mg
= 
Since, it is given that lethal dose is 10.0 g. Hence, number of cans are calculated as follows.
No. of cans = 
= 
= 280.58
= 281 (approx)
Thus, we can conclude that 281 cans of soda would be lethal.
The presence of potential energy between particles supports the shape of a heating curve.
<h2>Potential energy and heating curve</h2>
The existence of potential energy between particles supports the shape of a heating curve because potential energy causes the heating curve flat as well as in curve form. The heating curves show how the temperature changes as a substance is heated up.
The potential energy of the molecules will increase anytime energy is being supplied to the system but the temperature is not increasing so when the heating curve go flat it means there is potential energy so we can conclude that the existence of potential energy between particles supports the shape of a heating curve.

Hydrostatic pressure is independent of directions.
Kinetic energy is what a baseball use while traveling in the air
Answer:
3.1 m/s²
Explanation:
Apply Newton's second law:
∑F = ma
40 N = (13 kg) a
a ≈ 3.1 m/s²
