a. neutron stars
d. main sequence stars
Are smaller than the sun but I'm not sure about white dwarfs because a typical white dwarf is about as massive as the <span>Sun, yet only slightly bigger than the Earth.</span>
Answer:
<em>C. planetary accretion</em>
Explanation:
<em>Astronomers think planets formed from interstellar dust gases that clumped together in a process called </em><u><em>planetary accretion</em></u><em>.</em>
Explanation :
An electrical circuit can be either connected in series or parallel.
Series combination: The current flowing in each resistor is the same and the equivalent resistance is given by :
Parallel combination: The voltage for all components in the parallel combination is the same. The equivalent resistance is given by :
So, our of given options the correct one is (b) because the current flowing in both the resistors is the same.
Machines capable of manufacturing exactly the same component time after time,
with exactly the resistance you want, would be very expensive, and so would the
products they turn out. A resistor would cost a dollar instead of a few pennies.
The machine itself, and its output, work within tolerances.
The cheapest mass-produced resistors are guaranteed to be within 20% above
or below the resistance marked on them. And you know what ? For most bench-
work and prototyping, that's usually close enough.
