Reviewing Interactive Solution 5.46 will help in solving this problem. A stone is tied to a string (length = 0.551 m) and whirle

morpeh [17]

Answer:

The speed of the stone is

v = 7.45 m/s

Explanation:

Length, L=0.551m

maximum tension in the spring = 9.6%

So let speed of stone be

Tv = TH + 9.6/ 100 * TH

Tv - m*g = m*v^2/L

TH = m*v^2 / L

Factor mass to cancel in the equation

Solve to v

v^2= L*g*100 / 9.6

Replacing numeric:

v^2=0.551m*9.8m/s^2*100 / 9.6

v = sqrt( 56.24 m^2/s^2)

v = 7.45 m/s

Which of the following best explains how budgeting helps consumers reach their financial goals? A)budgets provide consumers with

miv72 [106K]

A budget is a guide that keeps you on the path to reach your financial goals. Budgeting keeps your finances under control, shows when you need to make adjustments to your spending, and helps you decide where your money goes instead of wondering where it all went.

Budgeting helps you answer these important questions:

Where does all my money go?

Is there a way to spend less?

How will I handle unexpected expenses like replacing a broken cell phone or repairing my car?

How can putting money into savings help me with some of my bigger financial goals?

Budgeting helps you achieve academic and financial goals.

Writing down your goals is the first step in creating a plan to make them realities. A budget will also help you prepare for unexpected expenses and obstacles. Budgeting involves challenging decision-making, but setting goals will make the tough choices a little easier.

As you create a budget, you’ll want to set short-, medium-, and long-term goals and track your progress toward achieving them.

The mean diameters of planets A and B are 8.1 × 103 km and 1.4 × 104 km, respectively. The ratio of the mass of planet A to that

lisabon 2012 [21]

Answer:

dA/dB = 4.955

Approximately, the ratio is 5/1

(Where dA is mean density for planet A while dB is mean density for planet B)

Explanation:

Mass of A = mA

Mass of B = mB

mA/mB = 0.96

Mean radius for A = mA = (8.1 × 10^3)/2 = 4.05 × 10^3 km

Mean radius for B = mB = (1.4 × 10^4)/2

= 7×10^3km

Density = mass/volume

Volume of a sphere = 4/3Πr3

Mean volume for A = (4/3) × Π × (4.05 × 10^3)^3

= 2.784 × 10^11 km3

Mean volume for B = 4/3×Π×(7×10^3)^3

= 1.437 × 10^12km3

Since m/v = d ( where m = mass, v = volume and d = density)

mA = 2.784 × 10^11 km3 × dA ...equation 1

mB= 1.437 × 10^12km3 × dB... equation 2

but mA/mB= 0.96

mA = 0.96 × mB

substitute for mA in equation 1

0.96 × mB = 2.784 × 10^11 x dA equation 3

Substitute for mB in equation 3..

(refer to equation 2)

0.96×1.437×10^12 × dB = 2.784 × 10^11 × dA .....equation 4

divide through by the coefficient of dA

dA = (0.96×1.437×10^12×dB)/(2.784 × 10^11)

divide through by dB

dA/dB = 4.955

therefore, the ratio of dA to dB is 5/1

Therefore, the mean density of A is almost five times that of B
