Answer:
The work done on the gas = 2PV
Explanation:
In this question, we need to apply the basic gas laws to determine the word done.
For this question, we need to draw a PV diagram (a pressure-volume diagram), which I have made and attached in the attachment. So please refer to that attachment. I will be using this diagram to solve for the work done on the gas.
So, Please refer to the attachment number 1. where x -axis is of volume and y-axis is of pressure.
As we know that, the work done on the gas is equal to the area under the curve.
W = Area of the triangle
W = 0.5 x ( base) x ( height)
W = 0.5 x (BC) x (AC)
W = 0.5 x (3V-V) x (3P-P)
W = 2PV
Hence, the work done on the gas = 2PV
Answer
we know,
where
E = energy
h = planks constant
λ = wavelength
from the above equation, we can see that energy is inversely proportional to wavelength.
that is why
Violet color light has low wavelength but the energy of Violet light is very high whereas red light has low energy and high wavelength.
Answer: Heart can beat 140 times in = 2 minutes
Answer:
(a)-0.701m
(b)-0.674m/s
Explanation:
Given a = -0.24,m/s² Xo = 0.170m, u = 0.190m/s
X = Xo + ut +1/2at²
X = 0.170 + 0.190×3.6 + 1/2×(-0.24) 3.6² = -0.701m
(b) its velocity at the end of this time interval is v
v = u + at
= 0.190 + (-0.24)× 3.6 = -0.674m/s
V1 =16 m/s and V2 =24 m/s. Constant acceleration = 9.8 m/s. The range for a horizontal drop is R=V1* the square root(2h/g. R1=16 * the square root of 2*5.4/9.8. =16.796 meters. And R2= 24 * the square root of 2*5.4/9.8 = 25.194. R2 - R1 = how far apart the two vessel will be. 25.194 - 16.796 = 8.398 or 8.4 meters
