The speed of the yacht : 100 km/h
<h3>Further explanation </h3>
Linear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration
- At constant velocity motion:
the speed of vo = v = constant
acceleration = a = 0
Δx = vt or x = xo + vt
An equation of constant velocity motion
x = distance = m
v = speed = m / s
t = time = seconds
A yacht sailed at a steady speed for 0.5 hours, and traveled 50 kilometers
so the velocity/speed:
Answer: The volume of tank is 17.5 L.
Explanation:
Given: Mass of methane = 173 g
Pressure = 15.1 atm
Temperature = 298 K
Molar mass of methane is 16.04 g/mol.
Therefore, moles of methane are calculated as follows.
Now, ideal gas equation is used to calculate the volume as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.
Thus, we can conclude that volume of the tank is 17.5 L.
Answer:
Kinetic energy increases
Explanation:
Kinetic energy is energy that kinda only happens when somethings like moving so if something is moving super fast its kinetic energy is increasing but if something is slowing down from fast to slow its kinetic energy is decreasing that make sense?
Answer:
The pressure of the gas is 0.35 atm.
Explanation:
We can find the pressure of the gas by using the Ideal Gas Law:
Where:
V: is the volume = 605 mL = 0.605 L
n: is the number of moles = 0.00803 moles
T: is the temperature = 39 °C = 312 K
R: is the gas constant = 0.082 L*atm/(K*mol)
Hence, the pressure is:
Therefore, the pressure of the gas is 0.35 atm.
I hope it helps you!
