A ceiling fan draws a current of 0.625 A and has a voltage of 120 V. The resistance of the ceiling fan, to the nearest whole num
Fiesta28 [93]
So we want to know what is the resistance of the ceiling fan if the current I=0.625 A and the voltage V=120 V. So we can get the resistance from Ohms law: I=V/R where I is the current, V is voltage and R is resistance. So the resistance is R=V/I. Now we input the numbers and get: R=120/0.625=192 Ω. That is resistance to the closest whole number.

A 0.0208 m diameter coin rolls up a 18.0◦ inclined plane. The coin starts with an initial angular speed of 56.0 rad/s and rolls
anastassius [24]

Answer:

h = 0.0259 m

Explanation:

given,

diameter of the cone = 0.0208 m

                     radius,r = 0.0104 m

angle of inclination,θ = 18°

initial angular velocity, ω_i = 56 rad/s

final angular velocity ,ω_f = 0 rad/s

height, h = ?

Rotational kinetic energy

KE_r = \dfrac{1}{2}I\omega^2

Moment of inertia of coin

I = \dfrac{1}{2}MR^2

so,

KE_r = \dfrac{1}{4}MR^2\omega^2

Transnational Kinetic energy

KE_t = \dfrac{1}{2}Mv^2

v = r ω

KE_t = \dfrac{1}{2}MR^2\omega^2

now,

using conservation energy

Kinetic energy of the coin is converted into the potential energy  

KE_r + KE_t = PE

\dfrac{1}{4}MR^2\omega^2 + \dfrac{1}{2}MR^2\omega^2 = Mgh

\dfrac{3}{4}R^2\omega^2=gh

\dfrac{3}{4}\times 0.0104^2\times 56^2=9.8\times h

h = 0.0259 m

Vertical height gain by the coin is equal to 0.0259 m
