Baking soda and vinegar are pretty much the answers to every cleaning prayer. Pour a half cup of baking soda in the disposal and then add a chaser of a cup of white vinegar. It will bubble, which is what you want. Let it do its magic for a good 10 minutes and then turn on the water and disposal.
A hiker climbs to the top of a mountain at rate of 0.5 m/hr. The speed of hiker is 1.3 x 10⁻⁴ m/s and the velocity of the hiker is 1.3 x 10⁻⁴ m/s west.
Speed is a scalar quantity. It is used to measure the distance traveled in a period of time. It is represented by -
s = d/Δt
where,
s = speed
d = distance
Δt = change in time
Velocity is a vector quantity. It is used to measure the change in position, that is, displacement over the change in time. It is represented by -
v = Δs / Δt
where,
v = velocity
Δs = change in position/displacement
Δt = change in time
The standard unit of velocity and speed both is m/s.

Answer:
The value of partial pressure of oxygen 
= 83.66 K pa
Explanation:
Volume of oxygen = 80 liters
Temperature = 50°c
The total pressure = 96 K pa
The partial pressure of water at 50°c is calculated from the tables.
= 12.344 K pa
The total pressure is given by
Put all the values in the above equation we get
96 = 12.344 +
96 - 12.344
= 83.66 K pa
This is the value of partial pressure of oxygen.
