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
Use energy conservation, since no energy is lost it must be constant.
E = 0.5mv² + mgh
At release the velocity v = 0 and the height is h.
E = 0 + mgh
At impact the height h = 0 and the velocity is v.
E = 0.5mv² + 0
Since the energy E is conserved:
0.5mv² = mgh
the mass m cancels and the equation becomes:
0.5v² = gh
h = 0.5v²/g
when g = 9.81 and v = 22:
h = 24,66
I’m so so sorry I wish I could help.... My best answer is no because they have different shapes but I am not sure
Hello!!
For calculate the Velocity of the wave let's applicate the formula:

Answer:
Magnitude of Force : 0.8 N
Explanation:
We know that the velocity of this particle changes from 15ms⁻¹, or in other words 15m / s, to the respective velocity 25m / s over the course of 2.5 seconds. Given this information we can determine the acceleration of the particle,
a = v₁ - v₂ / t = 25 - 15 / 2.5 = 10 / 2.5 = 4m / s²
Knowing the acceleration we can calculate the magnitude of the force using the formula f = ma - Newton's second law of motion,
f = m a = 200g 4m / s² = 800 g m / s²
Remember however that Newtons are in the standard units kg m / s². Therefore we have to convert 800 g to kg to receive our solution,
800 g = 800 / 1000 kg = 0.8 kg,
Magnitude of Force = 0.8 N ; Solution = Option B
