Answer:
Faith, to me is almost like hope but for faith you need to believe. Some people associate the word faith with religion. But that's not it. Faith is really just a stronger term than believing someone. Like you can believe in someone but not have faith in that same person. You can have faith in someone but to do that you have to believe and trust them.
Explanation:
the potential energy is increasing through steps A & B, then decreases at C.
An electromagnet is made from a coil of wire which acts as a magnet when an electric current passes through it. Often an electromagnet is wrapped around a core of ferromagnetic material like steel, which enhances the magnetic field produced by the coil.
Air spaces are used in insulation because air is a poor conductor.
Answer:
Work = 6912 joules
Explanation:
Non-conservative forces are dissipative forces such as friction or air resistance. These forces take energy away from the system as the system progresses, energy that you can't get back. These forces are path dependent; therefore it matters where the object starts and stops.
Total mass = 40 + 8 = 48kg
Initial speed u= 6 m/s
Final speed v = 3*initial
Final speed v = 3* 6 = 18 m/s
Distance s = 15
Acceleration a is?
V² = U² + 2aS
18² = 6² + 2a*15
324 = 36 + 30a
324-36= 30a
288 = 30a
288/30 = a
9.6= a
Force = mass* acceleration
Force = 48*9.6
Force = 460.8N
Work = force*distance
Work = 460.8*15
Work = 6912 joules
