Answer:
5,213mg
Explanation:
So, there are multiple ways to convert the different metric units, but I am going to explain how I was taught in elementary school, since it's the most simplest explanation.
To start off with, you want to memorize this saying:
King Henry Died By Drinking Chocolate Milk
Each beginning letter stands for a different metric unit.
Kilo, Hecto, Deka, Base, Deci, Centi, Milli
Base stands for your base, for instance, meter, gram, and liter would be considered your base units.
dg stands for Decigram, and mg stands for Milligram.
Then, you want to write this out:
KHDBDCM
If you can remember that saying above, writing these letters should be easier.
Once you write that down, you need to draw an arrow from each letter, starting from the second D, since the second D stands for Deci. You will stop the arrow at M since M stands for Milli.
The arrow should look something like the picture attached.
Count how many bumps the arrow does. There are 2 in total.
You then move your decimal 2 places to the right, since that's where the arrow is going.
52.13dg = 5,213mg
Remember that the decimal is invisible once it becomes a whole number. So, the decimal isn't necessary.
In conclusion, the answer is 5,213mg.
I hope this helped, have a good day!
Answer:
The toy's energy is 18 J.
Explanation:
We have, a 4 kg toy is lifted off the ground and falls at 3 m/s. It is required to find toy's energy.
The toy will have kinetic energy due to its motion. The energy is given by :
So, the toy's energy is 18 J.
Answer:
Because the gravitational attraction of the Sun hold them in motion around it
Explanation:
For an object travelling in a straight path at constant velocity, the net force acting on the object must be zero.
The planets in the Solar System, however, do not experience a zero net force: in fact, the Sun exerts a gravitational attraction on them, whose magnitude is given by
where
G is the gravitational constant
M is the mass of the Sun
m is the mass of the planet
r is the average distance between the Sun and the planet
Due to the presence of this force, the Sun makes the planets 'deviating' from their straight path, forcing them to following an elliptical path around the Sun.
