Uniform circular motion is used in physics to describe the motion of an object traveling at a constant speed in a circle. The sp

eed of the object is called tangential velocity and it can be calculated using the formula above, where r is the radius of the circle and T is the time is takes for the object to make one complete circle, called a period. Which of the following formulas could be used to find the length of one period if you know the tangential velocity and the radius of the circle?

Answer:

  B)  T = 2πr/v

Step-by-step explanation:

To solve the given equation for T, multiply it by T/v.

v=\dfrac{2\pi r}{T}\\\\v\dfrac{T}{v}=\dfrac{2\pi r}{T}\cdot\dfrac{T}{v}\\\\T=\dfrac{2\pi r}{v} \qquad\text{simplify}

PLEASE HELP !!!!!<br>Solve.<br>y +30 &lt; 15<br><br>​
Troyanec [42]

Hello there! y < -15

To solve, isolate y. To do this, subtract 30 from both sides of the equation.

y + 30-30 < 15-30

y < -15

This is your final answer. The statement is saying that y must be less than -15 when you add 30 to it for your final answer to be less than 15.

I hope this was helpful and have a great rest of your day! :)

Find an equation equivalent to r = 10 sinθ in rectangular coordinates
Flura [38]

Answer:

x^{2} + y^{2} - 10\cdot y = 0

Step-by-step explanation:

The following expressions are used to transform from polar into rectangular form:

r = \sqrt{x^{2}+y^{2}}

\sin \theta = \frac{y}{\sqrt{x^{2}+y^{2}}}

Now, the variables are substituted and equation is finally simplified:

\sqrt{x^{2}+y^{2}} = 10\cdot \frac{y}{\sqrt{x^{2}+y^{2}} }

x^{2}+y^{2} = 10\cdot y

The equivalent equation in rectangular coordinates is:

x^{2} + y^{2} - 10\cdot y = 0
