2. which of the following is accurate when discussing specific neat?
o a. the specific heat of a gas can be measured at constant pressure.
o b. specific heat values for solids will never vary for different ranges of temperature
o c. the specific heat of a gas can be measured at constant volume only.
o d. specific heat values for liquids will never vary for different ranges of temperatur

The specific heat of a gas may be measured at constant pressure. - is accurate when discussing specific heat.

Explanation:

i wanna say it’s between b and d, leaning more towards b.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
