b. seismic waves need a medium for propagation.
Answer: The partial pressure of if the total pressure of the mixture is 3.9 atm is 0.975 atm
Explanation:
According to Raoult's law, the vapor pressure of a component at a given temperature is equal to the mole fraction of that component multiplied by the vapor pressure of that component in the pure state.
where, x = mole fraction of nitrogen in solution = 0.25
= partial pressure of nitrogen = ?
= Total pressure = 3.9 atm
Putting in the values :
The partial pressure of is 0.975 atm
SOLVED DOWN BELOW
Explanation:
In series the same current goes thru both resistors, equiv resistance is 200 ohms, then using ohms law
<em>I = 25/200</em>
<em>I= .125 amps or 125 ma</em>
__________
<em>R= r1 * r2 / r1 +r2</em>
<em>R= 100 * 100 / 100 + 100</em>
<em>R= 10000 / 200</em>
<em>R= 50 ohms </em>
Answer:
Slow
Explanation:
As we know that the time period of simple pendulum is given by
Where, l be the effective length of the pendulum and g be the acceleration due to gravity
As the length of the pendulum increase, then the tie period of the pendulum will also increase.
It means the clock run slow.
