An object of mass m is traveling in a circle with centripetal force Fc. If the velocity of the object is v, what is the radius o
borishaifa [10]

Hi there!

Recall the equation for centripetal force:
F_c = \frac{mv^2}{r}

We can rearrange the equation to solve for 'r'.

Multiply both sides by r:
r * F_c = mv^2

Divide both sides by Fc:
\boxed{ r= \frac{mv^2}{F_c}}

Which does not contain a lens?
Nutka1998 [239]
<span>A lens is a piece of glass or other transparent substance with curved sides for concentrating or dispersing light rays, used singly (as in a magnifying glass) or with other lenses (as in a telescope). A binoculars, an eye, and a camera all contains a lens. A mirror does not contain a lens.</span>

S_A_V [24]

In order to solve this problem, it is necessary to apply the concepts related to the Pressure according to the Force and the Area as well as to the pressure depending on the density, gravity and height.

In the first instance we know that the pressure can be defined as

P = \frac{F}{A}

Where

F= Force

A =  Mass

In the second instance the pressure can also be defined as

P = \rho gh

Where,

\rho=Density of Fluid at this case Water

g = Gravitational Acceleration

h = Height

If we develop the problem to find the pressure then,

P = \frac{F}{A}

P = \frac{F}{\pi r^2}

P = \frac{2*10^6}{\pi (0.1)^2}

P = 6.37*10^{7} Pa

Through the second equation we can find the depth to which it can be submerged,

P = \rho gh

Re-arrange to find h

h = \frac{P}{\rho g}

h = \frac{6.37*10^{7}}{1000*9.8}

h = 6499.4m
