ask for the given problem. Will First Judd town

00:00:09.099 --> 00:00:17.330 A:middle L:90%
to determine which is couldn't s O work function often

00:00:17.329 --> 00:00:26.049 A:middle L:90%
bury him, which is generated as w is equal
4
00:00:26.050 --> 00:00:33.789 A:middle L:90%
to two point for each electron vote says one electron
5
00:00:33.789 --> 00:00:40.120 A:middle L:90%
void is equal to 1.6 into tennis to minus 19
6
00:00:40.119 --> 00:00:46.649 A:middle L:90%
Jews. They're for W busy quick oh, 2.48
7
00:00:46.659 --> 00:00:52.219 A:middle L:90%
into 1.6 into tennis to minus 19 which is coming

00:00:52.219 --> 00:00:57.140 A:middle L:90%
gas tree for 96 feet into tennis to minus 19
9
00:00:57.380 --> 00:01:00.350 A:middle L:90%
Troop. So we're basically converting from electron were to
10
00:01:00.060 --> 00:01:12.579 A:middle L:90%
choose. Also a violent off light is given as
11
00:01:12.579 --> 00:01:19.200 A:middle L:90%
Lambda, which is 3 65 9 millimeter. So
12
00:01:19.200 --> 00:01:22.329 A:middle L:90%
if we try to convert it into meter, it
13
00:01:22.329 --> 00:01:25.819 A:middle L:90%
is going to be 3 65 into tennis. True
14
00:01:25.819 --> 00:01:32.120 A:middle L:90%
. Minus nine meters. Now. In this problem
15
00:01:32.120 --> 00:01:34.919 A:middle L:90%
, we need to find two quantities. The 1st
16
00:01:34.920 --> 00:01:42.900 A:middle L:90%
1 is Maxima Kinetic energy off in a trance and
17
00:01:42.900 --> 00:01:49.689 A:middle L:90%
the 2nd 1 is speed of rituals. Now here
18
00:01:49.689 --> 00:02:08.120 A:middle L:90%
we start Formula for four grand energy is denoted as
19
00:02:08.129 --> 00:02:16.329 A:middle L:90%
easy quote to each time See over Landa And here
20
00:02:16.340 --> 00:02:22.590 A:middle L:90%
EJ is equipped to which is no. This plan
21
00:02:22.590 --> 00:02:32.450 A:middle L:90%
is constant. C is equal to speed off light
22
00:02:38.439 --> 00:02:50.509 A:middle L:90%
and Lambda is known as virulent by substituting all the
23
00:02:50.509 --> 00:02:54.020 A:middle L:90%
values in the formula for E, that is next
24
00:02:54.020 --> 00:03:00.280 A:middle L:90%
time. See over Lambda, we put devices right
25
00:03:00.280 --> 00:03:05.349 A:middle L:90%
now, which is 6.63 into tennis to minus 30
26
00:03:05.349 --> 00:03:12.610 A:middle L:90%
for that is true. Second multiplied by three include
27
00:03:12.610 --> 00:03:15.120 A:middle L:90%
and Rescue eight made a per second, which is
28
00:03:15.120 --> 00:03:20.299 A:middle L:90%
valid for C over 3 65 in pretending it's two
29
00:03:20.300 --> 00:03:27.040 A:middle L:90%
minus nine meters, which is equivalent. And by
30
00:03:27.039 --> 00:03:30.560 A:middle L:90%
calculating this, we get it as 5.449 in good
31
00:03:30.560 --> 00:03:38.169 A:middle L:90%
earnest to minus 19 Druids when we consider the kind
32
00:03:38.169 --> 00:03:43.360 A:middle L:90%
of big energy here which we need to calculate which
33
00:03:43.360 --> 00:03:50.039 A:middle L:90%
is given by the formula e minus w. So
34
00:03:50.039 --> 00:03:57.620 A:middle L:90%
here Well, we already have. That is 5.449
35
00:03:57.629 --> 00:04:06.049 A:middle L:90%
into tennis to minus 90 minus w is 3.296 lead
36
00:04:06.060 --> 00:04:11.300 A:middle L:90%
, including minister minus 19 which we have already calculated
37
00:04:11.300 --> 00:04:15.250 A:middle L:90%
previously. So we're just coming as 1.40 to 1
38
00:04:16.439 --> 00:04:19.490 A:middle L:90%
one point for it one, including minus two minus
39
00:04:19.490 --> 00:04:31.239 A:middle L:90%
19 truths. We can convert this value Kinetic energy
40
00:04:31.240 --> 00:04:35.289 A:middle L:90%
music will do what we have court as 1.4 800
41
00:04:35.410 --> 00:04:41.069 A:middle L:90%
initial mine in jewels. Okay, in ju in
42
00:04:41.069 --> 00:04:42.350 A:middle L:90%
a triangle. So what we need to do?
43
00:04:42.350 --> 00:04:47.209 A:middle L:90%
1.40 to 1, including Mr minus 19 divided by
44
00:04:47.560 --> 00:04:51.659 A:middle L:90%
1.6 in good and Mr minus 90 which is coming
45
00:04:51.660 --> 00:04:59.639 A:middle L:90%
as zero point nine to a strong word as the
46
00:04:59.639 --> 00:05:09.680 A:middle L:90%
fighting on here. In order to calculate the answer
47
00:05:09.680 --> 00:05:14.370 A:middle L:90%
for B, that is speed off electrons calculate speed
48
00:05:14.370 --> 00:05:18.949 A:middle L:90%
off electrons. We need to use a formula for
49
00:05:18.949 --> 00:05:24.699 A:middle L:90%
kinetic energy which has given us half into M into
50
00:05:24.709 --> 00:05:29.339 A:middle L:90%
the square. But M stands for you're a music
51
00:05:29.339 --> 00:05:33.590 A:middle L:90%
culture 9.11 include Ennis to minus 31 kilogram riches.
52
00:05:33.589 --> 00:05:39.620 A:middle L:90%
Monster electron kind antic energy value be already called So
53
00:05:39.620 --> 00:05:42.250 A:middle L:90%
therefore, in order to comfort value off me,
54
00:05:43.839 --> 00:05:46.589 A:middle L:90%
it is going to be a squared off two times
55
00:05:46.589 --> 00:05:54.810 A:middle L:90%
kinetic energy over in. But you just tried to
56
00:05:54.810 --> 00:06:00.370 A:middle L:90%
conquer this right now. So it is two times
57
00:06:00.379 --> 00:06:04.500 A:middle L:90%
the value of kinetic energy is 1.481 include Ennis to
58
00:06:04.500 --> 00:06:11.540 A:middle L:90%
minus 90 over myself. Electron is 9.11 in true
59
00:06:11.540 --> 00:06:16.220 A:middle L:90%
penitence to minus 30. But so finally therefore we
60
00:06:16.220 --> 00:06:23.949 A:middle L:90%
get Risi quitter. 570 drew 08 points year for
61
00:06:24.839 --> 00:06:28.399 A:middle L:90%
which we can already does. 5.70 Neto, turn
62
00:06:28.399 --> 00:06:31.750 A:middle L:90%
the rest. Five meter per second since its velocity
63
00:06:32.339 --> 00:06:34.550 A:middle L:90%
. And this is going to be on, sir
64
--> A:middle L:90%
.
