A 5.0 g coin is placed 15 cm from the center of a turntable. The coin has static and kinetic coefficients of friction with the t
Kaylis [27]

Answer:

Angular speed will reach 6.833rad/s before the coin starts slipping

Explanation:

There is no question but I'll asume the common one: Calculate the speed of the turntable before the coin starts slipping.

With a sum of forces:

Ff = m*a

Ff=m*V^2/R

At this point, friction force is maximum, so:

\mu*N=m*V^2/R

\mu*m*g=m*V^2/R

Solving for V:

V=\sqrt{\mu*g*R}

V=1.025 m/s

The angular speed of the turntable will be:

ω = V/R = 6.833 rad/s   This is the maximum speed it can reach before the coin starts slipping.

William finds a piece of pure iron in his garden. After a few days, the iron begins to rust. What are the two types of substance
nordsb [41]
Answer: an element; a compound
A compound is a molecule with at least two kinds of atoms. Since iron is only containing Fe then it shouldn't be a compound.
After iron got rust reaction, it will have oxygen make it become iron oxide. The iron oxide having Fe and O so it is a compound.
