If water didnt expand when it froze then it would be more dense so ice would sink. If ice sunk then it would cause a lot of ocean life to die because of the cold and water levels to rise more.

Yes I agree.

The very basic fundamental to remember here is that the ice when expands causes the floating of itself on top of water. Thus, if ice stops expanding, it will not float on the top of water body and thus would sink and may cause the freezing additional water in the water bodies. This could happen in the Antarctic , Arctic and all cold regions. Rivers may stop flowing in cold regions as they all will be frozen and also the survival of species will become difficult

Lori’s family is on a road trip. They split their drive into the five legs listed in the table. Find the average velocity for ea
NARA [144]
It's not possible to answer the question exactly the way it's written.
That's because we don't know anything about the direction they
drive at any time during the trip. 

You see, "velocity" is not just a word that you use for 'speed' when
you want to sound smart and technical, like this question is doing. 
"Velocity" is a quantity that's made up of speed AND THE DIRECTION
of the motion.  If you don't know the direction of the motion, then you
CAN'T tell the velocity, only the speed.

Here are the average speeds that Lori's family drove on each leg
of their trip:

Speed = (distance covered) / (time to cover the distance) .

Leg-A:  
Speed = 15km/10min = 1.5 km/min

Leg-B:  
Speed = 20km/15min = (1 and 1/3) km/min

Leg-C  
Speed = 24km/12min = 2 km/min

Leg-D:  
Speed = 36km/9min = 4 km/min

Leg-E: 
Speed = 14km/14min = 1 km/min

From lowest speed to highest speed, they line up like this:

[Leg-E] ==> [Leg-B] ==> [Leg-A] ==> [Leg-C] ==> [Leg-D]
  1.0 . . . . . . . . 1.3 . . . . . . . 1.5 . . . . . . . 2.0 . . . . . . . 4.0 . . . . km/minute   

Whoever drove Leg-D should have been roundly chastised
and then abandoned by the rest of the family.  36 km in 9 minutes
(4 km per minute) is just about 149 miles per hour !

The current in a hair dryer measures 19 amps. The resistance of the hair dryer is 14 ohms. What is the voltage?
Masja [62]
Voltage  =  (current) x (resistance)

             =  (19 A)  x  (14 ohms)  =  266 volts .

Note:  Be careful using that thing ! 

It's dissipating

       I² R  =  (19 A)² x (14 ohms)  =  5,054 watts ! ! !

That's an awful lot of power for a blow-dryer ! 

The dryer is certainly not using very much of that power to run the fan. 
Most of it is being used to heat air.  5 kilowatts is more power than most
toasters or microwave ovens use, so please be careful with how much of
your hair or skin you expose to that hot-air blast.  You could probably cook
a meatloaf with it.
