Process is called condensation and it happens when heat is removed from gaseous system.
Answer: 12) 1.07 m/s (right) 13) 4.05 m/s 14) 73 m/s 15) 10.9 m/s
Explanation:
12) Conservation of momentum. Momentum is the produce of mass and velocity.
13(2) + 15(-5) = 13(-5) + 15v
v = 1.06666... ≈ 1.07 m/s (right)
13) 18(9) + 22(0) = 18v + 22v
v = 18(9)/40 = 4.05 m/s
14) 0.65(35) + 0.08(0) = 0.65(26) + 0.08v
v = 73.125
15) This is a bit trickier. Let's ASSUME you jump off at 7 m/s relative to the truck. Doing this, we can assume that the reference frame is moving along with the truck at 10 m/s
the conservation of momentum equation becomes
600(0) + 80(0) = 600v + 80(-7)
v = 0.9333333... m/s
adding back the velocity of the reference frame means the truck is now traveling.
10.9333333... ≈ 10.9 m/s
I don't know what your options are, but heat moves from the sun moves in 3 ways: radiation, conduction, and convection. I hope this helps at least a little
Answer:
b) 1.29 V
Explanation:
Potential Difference: This is the work done when one coulomb of charge moves from one point to another in an electric field
The expression for the potential difference is
Q = CV .................... Equation 1
Where Q = amount of charge, C = Capacitance of the capacitor, V = potential difference.
Making V the subject of the equation,
V = Q/C................. Equation 2
Given: Q = 4.5 µC = 4.5×10⁻⁶ C, C = 3.5 µF = 3.5×10⁻⁶ F
Substituting into equation 2
V = 4.5×10⁻⁶ /3.5×10⁻⁶
V = 1.2857 V
V ≈ 1.29 V.
Hence the right option is b) 1.29 V
C. Both mass and velocity increases
