Since the volume doesn't change, and we assume that that
no heat is allowed to escape from the container, the pressure
of the gas will be directly proportional to its absolute temperature.
Absolute temperature = Celsius temperature + 273 K.
at 50°C, the absolute temperature is 323 K .
at 30°C, the absolute temperature is 303 K.
So, as the gas is warmed, the pressure will rise to (323/303)
of where it started.
(323/303) x (2.00 atm) = (1.066) x (2.00 atm) = 2.132 atm
Answer:
A meteorologist is a scientist who studies weather Explanation:
Answer:
(a) k = 30.33 N/m
(b) a = 9.8 m/s²
Explanation:
First, we need to find the force acting on the bungee jumper. Since, this is a free fall motion. Therefore, the force must be equal to the weight of jumper:
F = W = mg
F = (65 kg)(9.8 m/s²)
F = 637 N
(a)
Now applying Hooke's Law:
F = k Δx
where,
k = spring constant = ?
Δx = change in length of bungee cord = 33 m - 12 m = 21 m
Therefore,
637 N = k(21 m)
k = 637 N/21 m
<u>k = 30.33 N/m</u>
<u></u>
(b)
Since, this is free fall motion. Thus, the maximum acceleration will be the acceleration due to gravity.
a = g
<u>a = 9.8 m/s²</u>
Answer:
well, as u can tell the top layer will always be the youngest layer aka the newest layer. The farther u go down the older the layers get. So the deeper u dig the farther back in time we see.
