Answer:
increase speed, decrease speed, and change direction
Explanation:
Answer:
Explanation:
Following relation exists between number of turns and volt
Volt in primary / volt in secondary = no of turns in primary / no of turns in sec
19000 / 120 = no of turns in primary / 159
no of turns in primary = 19000 x 159 / 120
= 25175 Ans .
Proton only. That’s the answer
<span>Energy of Photon emitted by heated lithium atom E = 2.961 Ă— 10â’19 J
We need energy for only one mole of photons n = 1
Total photons in one mole = 6.022x10^23 photons / mole
Total Energy = n x h x E => 1 x 6.022x10^23 x 2.961 Ă— 10^â’19
Total Energy = 1.783x10^5 J</span>
