The period t of a simple pendulum is given by t = 2π formula887.mml, where l is the length of the pendulum and g is the accelera

tion due to gravity. thus if l and t are measured, we can estimate g with g = 4π2l/t2. assume that the period is known to be t = 1.49 s with negligible uncertainty and that l is measured to be 0.559 ± 0.005 m. estimate g, and find the uncertainty in the estimate. note: when doing calculations, use pi = 3.1416.

Filling in the given numbers, you have

... g = 4(3.1416/1.49)²·0.559 ≈ 9.9403

The error is proportional to the length, so is

... ±∆g = ±(0.005/0.559)g = ±0.0889

The estimate for the value of g is 9.9403 ± 0.0889 m/s².

Find the missing angle.
Gekata [30.6K]

Answer:

total angle of a triangle = 180°

other two angles = 85° , 65°

∴ the missing angle = 180 - ( 85 + 65 )

                                 = 180 - 150

                                 = 30

hope this answer helps you..

10 divided by 3 long division
sesenic [268]

Okay so the first thing we need to do is clarify the terms so that you know what each part of the division is:

  • The first number, 10, is called the dividend.
  • The second number, 3 is called the divisor.

What we'll do here is break down each step of the long division process for 10 divided by 3 and explain each of them so you understand exactly what is going on.

<h2>10 divided by 3 step-by-step guide</h2><h3>Step 1</h3>

The first step is to set up our division problem with the divisor on the left side and the dividend on the right side, like we have it below:

  __

3| 10

<h3>Step 2</h3>

We can work out that the divisor (3) goes into the first digit of the dividend (1), 0 time(s). Now we know that, we can put 0 at the top:

   _0_

3 | 10

<h3>Step 3</h3>

If we multiply the divisor by the result in the previous step (3 x 0 = 0), we can now add that answer below the dividend:

 _0_

3 | 10

    0

<h3>Step 4</h3>

Next, we will subtract the result from the previous step from the second digit of the dividend (1 - 0 = 1) and write that answer below:

 ___

3 | 10

- 0

__

1

<h3>Step 5</h3>

Move the second digit of the dividend (0) down like so:

 __0_

3 | 10

 - 0

-----------

10

<h3>Step 6</h3>

The divisor (3) goes into the bottom number (10), 3 time(s), so we can put 3 on top:

 __03_

3 | 10

- 0

___

10

<h3>Step 7</h3>

If we multiply the divisor by the result in the previous step (3 x 3 = 9), we can now add that answer below the dividend:

 _03_

3 | 10

- 0

__

10

 9

<h3>Step 8</h3>

Next, we will subtract the result from the previous step from the third digit of the dividend (10 - 9 = 1) and write that answer below:

  __03_

3 | 10

- 0

__

10

-9

_

1

<h3>So, what is the answer to 10 divided by 3?</h3>

Your answer is the top number, and any remainder will be the bottom number. So, for 10 divided by 3, the final solution is:

<h2>3 </h2><h2> - Remainder 1</h2><h2>Extra calculations for you:</h2>
  • Using a calculator, if you typed in 10 divided by 3, you'd get 3.3333.
  • You could also express 10/3 as a mixed fraction: 3 1/3
  • If you look at the mixed fraction 3 1/3, you'll see that the numerator is the same as the remainder (1), the denominator is our original divisor (3), and the whole number is our final answer (3).
