Answer: almost 12 years
Explanation:
Using the radial velocity method, planet hunters can track a sun's spectrum, to determine whether the sun has planets. The spectrum appears first slightly blue-shifted, and then slightly red-shifted. If the shifts are regular, repeating themselves at fixed intervals of days, months, or even years, it is almost certainly caused by a body orbiting the sun, tugging it back and forth over the course of its orbit. Because of the gravitational pull of Jupiter (about 3,000 times the mass of Earth), In which its average distance from the sun is 480 millions miles and takes nearly 12 years to make one revolution.
Answer: 22.7 meters
Explanation: The distance traveled is how much the ball has rolled in total, this means the lenght of the path that it has followed from begining to end.
Since it first travels 13.2 meters and then 9.5 meters, if we sum this quantities:
13.2 + 9.5 = 22.7 meters
So 22.7 is the distance that the ball has traveled.
Answer:
496.57492 kg/m³
Explanation:
= Atmospheric pressure = 101300 Pa
= Density of water = 1000 kg/m^3
= Height of water = 21.8 cm
= Height of fluid = 30 cm
g = Acceleration due to gravity = 9.81 m/s²
= Density of the unknown fluid
Absolute pressure at the bottom
The density of the unknown fluid is 496.57492 kg/m³
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:
length of one side of the coil is 0.1083 m
Explanation:
given data
no of turn = 269
coil rotates = 113 rad/s
magnetic field = 0.222-T
peak output = 79.2 V
solution
we will apply here formula for maximum emf induced in a coil that is
εo = N × A × B × ω ........................1
and here Area A = l²
so
l = 
put here value of A from equation 1
I = 
put here value and we will get
l = 
l = 0.1083 m
