00:00:03.149 --> 00:00:07.960 A:middle L:90%
for this question were asked to calculate the time they're
2
00:00:07.960 --> 00:00:12.890 A:middle L:90%
required to 2,000,000,000 ting eso here. We're gonna use
3
00:00:12.890 --> 00:00:15.929 A:middle L:90%
this one there. That walk the work equals to
4
00:00:15.929 --> 00:00:18.570 A:middle L:90%
the power comes the time we're looking for the time
5
00:00:18.570 --> 00:00:22.949 A:middle L:90%
. So time English too worked up over power and
6
00:00:22.949 --> 00:00:26.089 A:middle L:90%
how to calculate the words we're gonna use the energy
7
00:00:26.089 --> 00:00:31.519 A:middle L:90%
to technical work. So the work that we're gonna
8
00:00:31.530 --> 00:00:35.460 A:middle L:90%
feel really the tank equals to the potential energy of
9
00:00:35.469 --> 00:00:39.140 A:middle L:90%
all the water and the petition energy of water is
10
00:00:39.140 --> 00:00:41.460 A:middle L:90%
actually the the weight of the water times the highly
11
00:00:41.460 --> 00:00:44.850 A:middle L:90%
water So the weight of the water see em.
12
00:00:45.439 --> 00:00:51.780 A:middle L:90%
Water equals to the desert water times the ballroom,
13
00:00:51.780 --> 00:00:56.049 A:middle L:90%
a clover, tink and kiss Our tank is a
14
00:00:56.049 --> 00:01:00.390 A:middle L:90%
, um this American Tink. So we do supply
15
00:01:00.390 --> 00:01:06.370 A:middle L:90%
. Oh, we're to supply the form there for
16
00:01:06.650 --> 00:01:08.579 A:middle L:90%
a spare the bottom of a spare. So that
17
00:01:08.590 --> 00:01:14.930 A:middle L:90%
is thrilled for pi times the radius tell Cube in
18
00:01:14.930 --> 00:01:21.430 A:middle L:90%
terms visit water, which is given by 62 15
19
00:01:22.140 --> 00:01:26.150 A:middle L:90%
So, um, that's over mass. So the
20
00:01:26.150 --> 00:01:33.420 A:middle L:90%
way of the water and the energy equals to the
21
00:01:33.420 --> 00:01:37.750 A:middle L:90%
work equals two. The weight of the water times
22
00:01:37.750 --> 00:01:42.939 A:middle L:90%
to hide the water and that equals two, um
23
00:01:42.950 --> 00:01:45.870 A:middle L:90%
, this December. Let's just calculated Cool later,
24
00:01:45.879 --> 00:01:48.159 A:middle L:90%
Okay? And h here, we know that,
25
00:01:48.159 --> 00:01:53.620 A:middle L:90%
uh, we just use LBO letters, and we're
26
00:01:53.620 --> 00:01:57.959 A:middle L:90%
plugging ever. Well, you understand the height here
27
00:01:57.969 --> 00:02:06.510 A:middle L:90%
is 72 feet. Okay, So the last step
28
00:02:06.519 --> 00:02:09.210 A:middle L:90%
is to divide it to divide this work by the
29
00:02:09.210 --> 00:02:15.370 A:middle L:90%
power and C equals two zombie over P. So
30
00:02:15.370 --> 00:02:20.759 A:middle L:90%
that's and James H. Over P. And he
31
00:02:20.759 --> 00:02:27.580 A:middle L:90%
here we know is 550. What's and this is
32
00:02:27.580 --> 00:02:31.729 A:middle L:90%
roughly we'll talk another battle and calculated It's roughly Oh
33
00:02:32.520 --> 00:02:36.830 A:middle L:90%
, 16 hours, 30 minutes.
