Answer:
17 ohms
Explanation:
Given that,
In a series circuit there are 17 light bulbs, each providing 1 ohm of resistance.
We need to find the total resistance of the circuit.
The equivalent resistance for series combination is given by :
![R_{eq}=R_1+R_2+....](https://tex.z-dn.net/?f=R_%7Beq%7D%3DR_1%2BR_2%2B....)
For 17 light bulbs, the equivalent resistance is given by :
![R_{eq}=R+R+....\text{upto 17 terms}\\\\R_{eq}=17R\\\\=17](https://tex.z-dn.net/?f=R_%7Beq%7D%3DR%2BR%2B....%5Ctext%7Bupto%2017%20terms%7D%5C%5C%5C%5CR_%7Beq%7D%3D17R%5C%5C%5C%5C%3D17)
Hence, the total resistance is 17 ohms. Hence, the correct option is (d).
Answer:
Positron emission
Explanation:
Positron emission involves the conversion of a proton to a neutron. This process increases the mass number of the daughter nucleus by 1 while its atomic number remains the same. The new neutron increases the number of neutrons present in the daughter nucleus hence the process increases the N/P ratio.
A positron is usually ejected in the process together with an anti-neutrino to balance the spins.
