Given that,

The radius of a flywheel, r = 20 cm = 0.2 m

The centripetal acceleration experienced on the edge of the flywheel = 900 cm/s² = 9 m/s²

To find,

The speed of a point on the edge.

Solution,

The formula for the centripetal acceleration is given by :

$a=\dfrac{v^2}{r}\\\\v=\sqrt{ar} \\\\v=\sqrt{9\times 0.2} \\\\=1.34\ m/s$

Hence, the required speed is 1.34 m/s

Answer:

$\omega = 4.5\times 10^{-2} rad/s$

Explanation:

Given data:

Rotating cylinder length = 9 mi

diameter of cylinder is 5.9 mi

we know that linear acceleration is given as

a = r ω^2

where ω is angular velocity

so $\omega = \sqrt{\frac{a}{r}}$

$r = \frac{5.9}[2} \frac{1609 m}{1 mi} = 4.746\times 10^{3} m$

$\omega = \sqrt{\frac{9.80}{4.746\times 10^{3}}}$

$\omega = 4.5\times 10^{-2} rad/s$

Leftover planetesimals that formed in the region of the solar system now occupied by the jovian planets are called

rewona [7]

Answer:

Comets

Explanation:

Comets are planetary celestial bodies consisting of ice and dust, sometimes rocky particles formed in the region of the solar system. Long-period comets propagate towards the Sun by gravitational perturbations caused by passing stars. Some comets usually hyberbolic comets, move through the inner Solar System prior to entering the interstellar region. Short period comet lies beyond the orbit of the Neptune.

The Jovian planets include Jupiter, Saturn, Uranus, and Neptune.

Therefore, leftovers of comets (planetesimal bodies) formed in the region of the solar system that are now occupied by the Jovian planets is due to the dusty particles associated with the comets.

A vector has a component of 10 m in the x-direction, a component of 10 m in the y-direction, and a component of 5 m in the z dir

Kobotan [32]

The magnitude of this vector is 15

A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity. Examples of vectors in nature are velocity, momentum, force, electromagnetic fields, and weight.

The magnitude of a vector formula is used to calculate the length for a given vector (say v) and is denoted as |v|. So basically, this quantity is the length between the initial point and endpoint of the vector.

Let vector be = a

component of vector in x direction = 10 i

component of vector in y direction = 10 j

component of vector in z direction = 5 z

vector a = 10 i + 10 j + 5 z

magnitude of vector a = |a| = $\sqrt{10^{2} +10^{2} + 5^{2} }$

= 15
