Answer:

<em>Examples</em>

  1. Aeroplane taking a flight.
  2. Triggering a bullet in sky.
  3. Kicking a ball in sky.

<em>Non-Examples</em>

  1. A moving vehicle.

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

How are the ice cubes and water similar?<br> How are they different?
KATRIN_1 [288]

Answer:

As the liquid cools down, the amount of potential energy is reduced and the molecules start to move slower. When the water temperature reaches around 0°C, the molecules stick together and form a solid – ice

The "stuff" (molecules) in water is more tightly packed than in ice, so water has greater density than ice. Don't let the fact that ice is a solid fool you! As water freezes it expands. So, ice has more volume (it takes up more space, but has less density) than water

Change the following data into scientific notation.<br><br> 5 000 000 km
RoseWind [281]
To find out scientific notation, you want to make sure that number is less than 10. So do 5.000000, you don't rally need the zeros but I just want to make my point. So use 10^x meaning ten the whatever power adds zeros like 5.000000x10^6 meaning it is increasing it by six zeros moving it out of the decimals and letting become 5,000,000.
