victus00 [196]3 years ago
3 0

Answer and Explanation:

DE BROGLIE 'S HYPOTHESIS :

  • According to De broglie the matter have dual nature it can behave as particle as well as wave
  • According to this hypothesis all matter have wave like property and having wavelength.
  • The de broglie wavelength is given by \lambda =\frac{h}{P} here h is plank's constant and P is momentum
  • This hypothesis determines the probability of finding the object at a give point

a cyclist must travel 800 km. how many days will the trip take if the cyclist travels 8/h day at an average speed of 16km/h
sergey [27]
It would b 6 days and 6 hours
You would times 16 by 8 which gives 128km a day. To find how many days you would divide 800 by how many kilometres they cover a day which is 128
So 800/128 =6.25 which converts to 6 days and 6 hours.

Adolf and Ed are wearing harnesses and are hanging at rest from the ceiling by means of ropes attached to them. Face to face, th
exis [7]

Answer:

0.78 m

Explanation:

By the conservation of energy, the energy that they gain from potential energy, must be equal to the kinetic energy. So, for Adolf:

Ep = Ek

ma*g*ha = ma*va²/2

Where ma is the mass of Adolf, g is the gravity acceleration (10 m/s²), ha is the height that he reached, and va is the velocity. So:

100*10*0.51 = 100*va²/2

50va² = 510

va² = 10.2

va = √10.2

va = 3.20 m/s

Before the push, both of them are in rest, so the momentum must be 0. The system is conservative, so the momentum after the push must be equal to the momentum before the push:

ma*va + me*ve = 0, where me and ve are the mass and velocity of Ed. So:

100*3.20 + 81ve = 0

81ve = 320

ve = 3.95 m/s

By the conservation of energy for Ed:

me*g*he = me*ve²/2

81*10*he = 81*(3.95)²/2

810he = 631.90

he = 0.78 m

A solenoidal coil with 22 turns of wire is wound tightly around another coil with 330 turns. The inner solenoid is 21.0 cm long
Airida [17]

Answer:

0.00027646\ T

2.33\times 10^{-5}\ H

-0.04194 V

Explanation:

N_2 = Number of turns in outer solenoid = 330

N_1 = Number of turns in inner solenoid = 22

I_1 = Current in inner solenoid = 0.14 A

\dfrac{dI_2}{dt} = Rate of change of current = 1800 A/s

\mu_0 = Vacuum permeability = 4\pi \times 10^{-7}\ H/m

r = Radius = 0.0115 m

Magnetic field is given by

B=\mu_0\dfrac{N_2}{l}I\\\Rightarrow B=4\pi \times 10^{-7}\times \dfrac{330}{0.21}\times 0.14\\\Rightarrow B=0.00027646\ T

The  average magnetic flux through each turn of the inner solenoid is 0.00027646\ T

Magnetic flux is given by

\phi=BA\\\Rightarrow \phi=0.00027646\times \pi 0.0115^2\\\Rightarrow \phi=1.14862\times 10^{-7}\ wb

Mutual inductance is given by

M=\dfrac{N_1\phi}{I}\\\Rightarrow M=\dfrac{22\times 1.14862\times 10^{-7}}{0.14}\\\Rightarrow M=2.33\times 10^{-5}\ H

The mutual inductance of the two solenoids is 2.33\times 10^{-5}\ H

Induced emf is given by

\epsilon=-M\dfrac{dI_2}{dt}\\\Rightarrow \epsilon=-2.33\times 10^{-5}\times 1800\\\Rightarrow \epsilon=-0.04194\ V

The emf induced in the outer solenoid by the changing current inthe inner solenoid is -0.04194 V
