Answer:
The answer is 312.5j
Explanation:
The kinetic energy (KE):
KE=1/2*m*v^2
M= mass of the object
v= velocity of the object
We have;
m=25g
v=5m/s
KE=1/2*25g*5^2m/s
KE =312.5j
Hello there!
I can help you out with #15 to help get you started/ unstuck! :)
So I see you have your conversion table drawn! Fantastic!
So you start off by putting the GIVEN unit in the first (top) space.
12 g
Next, you put " 1 g " ( 1 gram ) below, and to the right of it. (Diagonal right 1 block).
Why 1 gram? Because the units g will cancel each other out!
So on the box NEXT to your 12 g, put ___kg. This will give you your new unit.
For now, you can search up how many kilograms there are in a gram but it'll be very helpful in the future to have it memorized. :)
Clarification:
"How many kg are there in a g?"
We do this because the bottom says " 1 gram," so since we're converting grams to kilograms, we're converting 1 gram to ___ kilograms.
After filling out your chart, multiply the tops together! Cancel out units, and use a calculator if it's allowed! :)
Summary:
1). Make an empty conversion table.
2). Start with the given unit in the top left space.
3). Move down, and to the right: Put 1 (unit). This will cancel the units out later.
4). Above the 1 (unit), put (???) (new unit).
To find (???) simply search it up. :)
Ex). "How many kg are there in 1 g?"
The units should cancel out on their own. :)
With this, it simply takes practice. I'm sure you'll get the hang of it in no time! :D

Answer:half of shorter Pipe
Explanation:
Fluid is Flowing through two horizontal pipes with pressure difference
Both pipes have same radius
Length of one Pipe is twice of other
Let Longer Pipe be denote by 1 and smaller by 2
From Hagen Poiseuille equation
Where 
viscosity of medium
L=length of Pipe
Q=discharge
D=diameter
For longer Pipe
----1
For smaller Pipe
------2
From 1 & 2 we get
volume flow rate of longer pipe is half of smaller pipe
A non-moving bike has wheels that aren't spinning and zero angular momentum, which makes it very easy for external torque to change the wheels' direction, making the bike harder to balance. Even when staying relatively motionless, though, a rider can balance a bike with some effort.
<span>One astronomical unit is equal
to the average distance between the Earth and the Sun. The answer is letter B. However,
the distance between the earth and the sun varies as the earth revolves around
the sun. but recent discoveries have proven the exact distance. It is also
equal to 149, 597, 870, 700 meters and was defined by the International
Astronomical Union. </span>
