While taking a bath, a person touches the metal case of a radio. The path through the person to the drainpipe and ground has a resistance of 4000 Ω . What is the smallest voltage on the case of the radio that could cause ventricular fibrillation? Estimate what was the power dissipated in the body during the impact?
9. In Fig.2
v1= √2(16)sin Wt V,
V2 =√2(24) sin(Wt +90°) V, and
v3=√2(15) sin(Wt -90°) V.
Determine the source voltage, e
determine the work done by a force F = xyi + yzj + xzk in taking a particle along the path defined by the equation r(t)=ti + 2t²j + t³k, 0≤t≤1 from t=0 to t=2.
- Say whether each of the following will make the electromagnet stronger, weaker or have no effect:
- Increasing the number of turns of wire. Stronger
- Decreasing the current passing through the wire.
- Putting the nail into the coil from the opposite direction
