Answer:
1.98 atm
Explanation:
Given that:
Temperature = 28.0 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (28 + 273.15) K = 301.15 K
n = 1
V = 0.500 L
Using ideal gas equation as:
PV=nRT
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L atm/ K mol
Applying the equation as:
P × 0.500 L = 1 ×0.0821 L atm/ K mol × 301.15 K
⇒P (ideal) = 49.45 atm
Using Van der Waal's equation
R = 0.0821 L atm/ K mol
Where, a and b are constants.
For Ar, given that:
So, a = 1.345 atm L² / mol²
b = 0.03219 L / mol
So,
⇒P (real) = 47.47 atm
Difference in pressure = 49.45 atm - 47.47 atm = 1.98 atm
Transverse wave = at right angles to the direction of the motion of the wave
in transverse wave medium particles will move perpendicular to the direction of motion of medium particles
they all are perpendicular to wave always
Longitudinal wave = back and forth in the direction of the motion of the wave
in longitudinal waves medium particles will move in the direction of wave and the motion is always in back and forth type
electromagnetic wave = alternating waves moving at right angles to each other
electromagnetic waves are combination of electric field and magnetic field which oscillates perpendicular to wave as well as they are perpendicular to each other
Answer:
Disregard a goal if you don't achieve it
Explanation:
This is because in achieving your targets/goals/dreams rewarding yourself for every small accomplishment is very important. It’ll help to keep you motivated and keep your head in the game. Similarly setting short and long-term objectives also plays a vital role. Setting a date is also important because it helps you to put your plan into action. However, disregarding a goal isn’t an option
