Answer:

The distance is 54.6 m

Explanation:

Given that,

Mass = 2.0 kg

Frictional coefficient = 0.21

Initial velocity = 15 m/s

We need to calculate the acceleration

Using formula of frictional force  

F = \mu mg

F=0.21\times2.0\times9.8

F = 4.12\ N

We need to calculate the acceleration

F = ma

a = \dfrac{F}{m}

a =\dfrac{4.12}{2.0}

a=2.06\ m/s^2

We need to calculate the initial velocity

Using equation of motion

v^2=u^2-2as

Put the value  

0=15^2-2\times2.06\times s

s = \dfrac{15^2}{2\times2.06}

s=54.6\ m

Hence, The distance will be 54.6 m.

A coil of area 0.320 m2 is rotating at 100 rev/s with the axis of rotation perpendicular to a 0.430 T magnetic field. If the coi
weqwewe [10]

Answer:

The maximum  emf generated in the coil is 60527.49 V

Explanation:

Given;

area of coil, A = 0.320 m²

angular frequency, f = 100 rev/s

magnetic field, B = 0.43 T

number of turns, N = 700 turns

The maximum emf generated in the coil is calculated as,

E = NBAω

where;

ω is the angular speed = 2πf

E = NBA(2πf)

Substitute in the given values and solve for E

E = 700 x 0.43 x 0.32 x 2π x 100

E = 60527.49 V

Therefore, the maximum  emf generated in the coil is 60527.49 V
