Answer:
a)W=20 KJ
b) ΔQ= 220 KJ
Explanation:
Given:
V₁=0.1 m^3, P₁=200 kPa and heat is added to the system such that system expands under constant pressure.
Therefore V₂= 2V₁= 0.2 m^3
a) Work transfer W= P(V₂-V₁)=
W=20 KJ
b) internal energy change ΔU= 200 KJ
from first law we know that ΔQ(net heat transfer)= ΔU + W
ΔQ=
ΔQ=
ΔQ= 220 KJ

Answer:
C. Why you must push harder to move a car farther.
Explanation:
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Hence, Newton's 2nd Law explains why you must push harder to move a car farther because of its mass. Thus, it is important to increase the force that the engine provides and decrease the mass of the car.
Answer:
a) 4.04*10^-12m
b) 0.0209nm
c) 0.253MeV
Explanation:
The formula for Compton's scattering is given by:
where h is the Planck's constant, m is the mass of the electron and c is the speed of light.
a) by replacing in the formula you obtain the Compton shift:
b) The change in photon energy is given by:
c) The electron Compton wavelength is 2.43 × 10-12 m. Hence you can use the Broglie's relation to compute the momentum of the electron and then the kinetic energy.
