Answer:Technician A
Explanation:
Technician A statement is correct as
The battery is required to start the vehicle which, in effect, rotates the alternator at sufficient speed to keep the battery charged. This means if the battery is low it is not possible to start the vehicle and thus we are unable to test the alternator.
That is the battery is pre-requisite to test the alternator. So the battery must be at least a 75 % charge to test the alternator.
Answer:
Part A the answer is the dielectric constant.
Part B Mica- mylar- paper- quartz
Explanation:
The capacity of a capacitor is given by
C = ε ε₀ A / d
Where the dielectric constant (ε) is the value of the material between the plates of the capacitor, we see that as if value increases the capacity also increases.
Another magnitude that we must take into account that the maximum working voltage, the greater the safer is the capacitor
the flexibility of the material must also be taken into account
Part A the answer is the dielectric constant.
Pate B order the materials from best to worst
Mica. The best ever
Mylar Flexible
Paper Low capacity, low working voltage, flexible
Quartz high dielectric, but brittle
The mass affects the kinetic energy because the more the mass the more energy is given to the object and the speed<span> affects by making it go faster and longer, so whenever speed goes up so does energy.</span>
Answer:
The bending of light as it passes from one medium to another is called refraction. The angle and wavelength at which the light enters a substance and the density of that substance determine how much the light is refracted. The bending occurs because light travels more slowly in a denser medium.
hope this helped :))
