How long must a simple pendulum be if it is to make exactly one swing per three seconds? (that is, one complete oscillation take
Stolb23 [73]
This is a physics question.

Use the formula for simple pendulum:

T = 2π √(L/g)

Where T is the period (time to complete a full oscilation), L is the lenght and g acceleration of gravity ≈ 9.81 m/s^2 .

So, solve for l:

√(L/g) = T / (2π)

L = [T / (2π) ] ^2 * g = [ 6.0s / (2π) ]^2 * 9.81 m/s^2 = 8.9 m

Answer: 8.9 m

If 75% of budget is 1200, what is the full budget using a table?
Alisiya [41]

Answer: full budget of 100% will be 1600

Step-by-step explanation:

If 75% = 1200

Full budget will be 100%

Represent the question as if 75% = 1200

Then 100% = x

Cross multiply:

75%x = 1200%

Divide both sides by 75%

x = 1200%/75%

x = 16 × 100

= 1600

Convert ( 4 , 300 ∘ ) to rectangular form.
Rasek [7]

The rectangular representation of the polar point of (4 , 300) is (2,- 2√3)

According to the statement

we have given a coordinates of the rectangle and we have to find the polar coordinates.

So, For this purpose, we know that the

We Use the conversion formulas to convert from polar coordinates to rectangular coordinates which are

x = rcosθ

y = rsinθ

Substitute the given values in it then

x=(4)cos(300)

y=(4)sin(300)

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.

x=(4)cos(60) -(1)

y= - (4)sin(60) -(2)

And then

x=(4)cos(60)  

x=(4)(1/2)

x = 2 -(3)

and

y= - (4)sin(60)

y= - (4)(√3/2)

y= - 2√3 -(4)

Replace (3) with (1) and (4) with (2)

then it becomes

x = 2 and y= - 2√3

The rectangular representation of the polar point of (4 , 300) is (2,- 2√3)
