A merry-go-round makes one complete revolution in 5.3 s. A 48.5 kg child sits on the horizontal floor of the merry-go-round 2.7

Marianna [84]

Answer:183.94 N

Explanation:

Given

Time Period $T=5.3 s$

mass of child $m=48.5 kg$

Radius $r=2.7 m$

Velocity $v=\frac{2\pi \cdot r}{T}$

$v=\frac{2\pi \cdot 2.7}{5.3}$

$v=3.20 m/s$

Now Centripetal Force will be Balanced by Frictional Force

Centripetal Force $F_c=m\cdot \frac{v^2}{r}$

$F_c=48.5\cdot \frac{3.2^2}{2.7}$

$F_c=183.94 N$

therefore Friction Force is 183.94 N

Describe the relationship between amperage, voltage, and, as well as resstance.

Nikolay [14]

Answer:

$I=\frac{V}{R}$

Explanation:

Ohms law says that the current in the conductor between the two points is directly related or directly proportional to the voltage by keeping a proportionality of constant which is called resistance.

Mathematically Ohms law can be written as,

$I=\frac{V}{R}$

Here, I is the current measure in ampere or amperage, V is voltage measure in voltage and R is resistance measure in Ohm.

Now the relation between the amperage, voltage and resistance will be,

$I=\frac{V}{R}$

Amperage=Voltage/Resistance
