Oxygen and hydrogen are kept under the same temperature and pressure. Oxygen molecule is 16 times more massive than hydrogen one
1 answer:
Answer:
The average speed of molecule of oxygen is one-fourth of the speed of the hydrogen molecule.
Explanation:
The kinetic energy of gas molecule is given by following equation:
Since the temperature (T) is constant for both molecules. Therefore, there kinetic energies will also be the same. Therefore,
<u>The average speed of molecule of oxygen is one-fourth of the speed of the hydrogen molecule.</u>

Answer:
Part 1. Pendulum clock is slower.
Part 2. Spring-loaded clock remains the same.
Explanation:
The period of a simple pendulum is given by
where = length of pendulum and
= acceleration due to gravity.
It is seen that the period is inversely proportional to the square root of the gravitational acceleration. So if gravity increases, period decreases and vice versa.
on the moon is about one-fifth that of the Earth. Hence, the pendulum will have a larger period, about twice (
). A larger period means it takes longer to finish an oscillation, so the pendulum clock is slower.
The period of a loaded spring is given by
where = the spring constant and
= mass of load on the spring.
It is seen that this relation does not depend on gravity nor does it have any parameter that depends on gravity: k is a constant of the spring that does not change while mass is independent of location.
Hence, the spring-loaded clock will remain the same.
As a note, one might assume that gravity affects the loaded spring because the load is 'pushed' down by gravity. In fact, only the equilibrium position is affected by gravity; it only determines where the oscillation starts from, not how long it takes.
Answer: The next 5 steps are.
step 2: Find the magnitude of vectors.
step 3: Calculate 'x' and 'y' components.
step 4: Sum the above obtained vector components.
step 5: Calculate the magnitude of Resultant Vector.
Step 6: Determine the direction of the resultant vector.
Explanation:
Let the two vectors be 'A' and 'B'.
Let A = and B =
It is given that, when solving a two dimensional, multi-charge problem, is to define the vectors.
So, step 1 is to define the vectors A and B.
In step 2, we find the magnitude of the vectors by,
In step 3, we find the components 'x' and 'y'
Then in step 4, we sum the components. Now we get the Resultant vector (R).
In step 5, Calculate the magnitude of 'R' using the above formula to find magnitude.
In step 6, we determine the direction of 'R'.
