A cardiac pacemaker can be affected by a static magnetic field as small as 1. 7 mt. pacemaker wearer comes to a long, straight wire carrying 28 amperes.
A pacemaker is a device that regulates an unsteady heartbeat. A pacemaker is inserted into one or more cardiac chambers using flexible, insulated wires called leads. The electrical pulses needed to change the heart rate are delivered by these lines. Some of the most recent pacemakers don't need leads.
The risk of problems is often quite low while having a pacemaker put. The primary worry is that the pacemaker will no longer be able to regulate the heartbeat due to a malfunction or a wire that has moved out of place. The average patient lived 101.9 months (or 8.5 years) after having a pacemaker implanted; at 5, 10, 15, and 20 years later, 65.6%, 44.8%, 30.8%, and 21.4% of patients were still living, respectively.

1) It's B. Ultraviolet rays cause substances to fluoresce.
2) It's D. The lens enlarges the image.
3) It's actually more powerful so it's B. People usually buy products based on quality than portability.
4) CORRECT
5) CORRECT
I believe the answer would be oxygeon deficit.
Answer:
Explanation:
Capacitance is defined as the charge divided in voltage.
Introducing a dielectric into a parallel plate capacitor decreases its electric field. Therefore, the voltage decreases, as follows:
Where k is the dielectric constant and the voltage of the capacitor without a dielectric
The capacitance with a dielectric between the capacitor plates is given by:
Where k is the dielectric constant and the capacitance of the capacitor without a dielectric. So, we have:
Therefore, a capacitor with a dielectric stores the same charge as one without a dielectric.
Answer:
When vectors are added or subtracted, the net force is called the resultant force.
