The chemical symbol always begins with a capital letter.

<span>∆U = μB = (1.5)(0.815) = 1.2225 joules</span>
<span>To produce a charge of 1.15 Coulombs in an object, we need to transfer = 1.15/(charge on an electron) number of electrons
As we know that, total charge on an electron = 1.60217662 Ă— 10 ^-19 coulombs
Hence, number of electrons required to move = 1.15/(1.60217662 Ă— 10 ^-19)
= 0.71777 x 10^19 electrons, i.e. 7.17 x 10^18 electrons upto 3 significant figures</span>
Velocity includes direction, for instance going 140 MPH is speed but going 140 MPH North is velocity
Answer:
95.47 C
Explanation:
Heat added = mass × heat capacity × rise in temperature
So, rise in temperature =
20000 / (0.05 × 4190)
Rise in temperature = 95.47 C
