jack peddles a stationary bicycle. the pedals of the bicycle are attached to a 1000 turn coil of area 0.10 m2. the coil rotates

tatuchka [14]

The maximum voltage generated in the coil is 3.14 V.

According to the question, we are provided that a bicycle turns 1000 of the area of 0.10 m2, where the coil rotates half a revolution per second, which is placed in a uniform magnetic field of 0.01 T.

Therefore, no .of turns the coil took, N = 1000

Area of the coil, A= 0.10 m²

Frequency of the system =0.5 revolutions per second

= 0.5 Hz

The intensity of the Magnetic field , B =0.01 T

So the Equation we refer to for the calculating the desired value

E(ind) = $-db/dt$

= -d(NBAcosωt) / dt

= − NBA d(cosωt) /dt

= NBAωsinωt

if sinωt=1,

maximum E(ind)= NBAω

Since we know, ω=2πf

Therefore, (Eind)max = NBA(2πf)

= (1000)(0.01)(0.1)(2π)(0.5)

(E(ind))max= 3.14v.

the value for the voltage we got is 3.14 V

Convert 70 mi/h to m/s. 1 mi = 1609 m. Answer in units of m/s. Plz help me now

melisa1 [442]

Answer:

70mi/h

1mile =1609 meters

1hour=3600 seconds

So,

70×1609/3600

112,630/3600

31.286 m/s

Hope this helps you

Which of the following does NOT describe the conversion of potential to kinetic energy? Question 12 options:

Marianna [84]

The option “The sum emitting light energy” does not describe the conversion of potential energy to kinetic energy.

Answer: Option A

Explanation:

The potential energy, the object's energy at rest while the kinetic energy is the energy the object in motion. So among the options given, a rocket leaving the Earth's atmosphere consists of conversion of potential energy as the thrusting force to kinetic energy of the movement of the rocket to space.

Similarly the stretching of rubber band is a form of elastic potential energy and when it is released, the band will vibrate which will be the converted kinetic energy.

Also, the avalanche is the falling of ice berg which were once in rest, so the potential energy of the ice berg will get converted to kinetic energy during avalanche.

The option that is the sun emitting light does not convert potential to kinetic energy, instead it converts potential to light energy.

A car traveling 75 km/h slows down at a constant 0.50 m/s2 just by "letting up on the gas." calculate (a) the distance the car c

Serjik [45]

Solution:

At 1st convert km/h to m/s. 1 km = 1000 m, 1 h = 3600 s, 1 km/m = 1000/3600 = 5/18 m/s

Initial velocity = 75 * 5/18 = 20.8 m/s

The car’s velocity decreases from 20.8 m/s to 0 m/s at the rate of 0.5 m/s each second. We have the final velocity, initial velocity, and the acceleration.

Now according to the equation determine the distance.

vf^2 = vi^2 + 2 * a * d

a = -0.5 m/s^2

0 = 20.8^2 + 2 * -0.5 * d

so d = 431.64 m

since we have the final velocity, initial velocity, and the acceleration. Use the following equation to determine time.

vf = vi + a * t

0 = 20.8 – 0.5 * t

Solve for t = 41 seconds

(c) the distance travels by it during the first and fifth second are.

d = vi * t + ½ * a * t^2

d1 = 20.8 * 1 – ½ * 0.5 * 1^2 = 20.55 m

The easiest way to the distance for the 5th second is:

d = vi * t + ½ * a * t^2, a = -0.5

d5 = 20.8 * 5 – ½ * 0.5 * 5^2 = 91.5 m

d6 = 20.8 * 6 – ½ * 0.5 * 6^2 = 106.8m

d6 – d5 = 15.3 m

this is the required solution.
