5213 mg is the answer
dmitriy555 [2]2 years ago

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!

Ms. Garcia’s car can go from rest to 25 m/s in 10 seconds. The car’s velocity changes at a uniform rate. How far does the car tr
vampirchik [111]

We will use this equation:

s = 1/2*a*t^2 + v0*t + s0

where:

s = space traveled

a = acceleration

t = time

v0 = initial speed

s0 = initial space

In this case::

v0 = 0

s0 = 0

So our equation will look like that now:

s = 1/2 * a * t^2

let's calculate the acceleration first of all:

a = (vf - vi) / t

where vf is the final speed and vi is the initial speed. t is the time.

a = (25m/s) / 10s = 2.5 m/s^2

Now we can calculate the space:

s = 1/2 * (2.5 m/s^2) * (10s)^2 = 125m

---

Hope it was helpful! Have a great day.

A soccer ball moving with an initial speed of 1.8 m/s is kicked with a
vova2212 [387]

Answer:

7.0 m

Explanation:

Step 1: Given data

Initial speed of the ball (u): 1.8 m/s

Acceleration (a): 6.1 m/s²

Final speed of the ball (v): 9.4 m/s

Step 2: Calculate the displacement (s) of the ball

The ball is moving with a uniformly accelerated rectilinear motion. We can calculate the displacement using the following suvat equation.

v² = u² + 2 × a × s

s = (v² - u²)/2 × a

s = [(9.4 m/s)² - (1.8 m/s)²]/2 × 6.1 m/s²

s = 7.0 m

What is the minimum (non-zero) thickness ttt of the film that produces a strong reflection for green light with a wavelength of
scZoUnD [109]

Answer:

200 nm.

Explanation:

The minimum thickness can be found using the following equation:

2t = \frac{m\lambda}{n}

Where:

t: is the thickness =?

m: is the order of interference = 1 (since it is minimum)

n: is the refractive index = 1.25

λ: is the wavelength = 500 nm

t = \frac{m\lambda}{2n} = \frac{500 nm}{2*1.25} = 200 nm

Therefore, the minimum thickness is 200 nm.

I hope it helps you!
