According to Joule's Law, we have the relationship between charge, voltage, and current:
W = Vq
where q is the charge
V is the voltage or the potential difference
W is the work done
From the given values and rearranging the equation:
V = 10J / 4.0x10^-2
V = 250 V
The voltage difference is 250 V
The kinetic energy should be 1,102.5 joules.
Fg = m • g so 60kg • 9.8 m/s•s = 588 N
Answer:
C
Explanation:
Answer A: A surface wave is a wave that travels along the surface of a medium.
Answer B, C: Electromagnetic waves are waves that have no medium to travel whereas mechanical waves need a medium for its transmission.
Answer D: The sentence in the answer D does not fit to the blank in the definition ( of the question )
