Answer:

the tangential velocity of the student is 4.89 m/s.

Explanation:

Given;

the radius of the circular path, r = 3.5 m

duration of the motion, t = 4.5 s

let the student's tangential velocity = v

The tangential velocity of the student is calculated as follows;

v = \frac{2\pi r}{t} \\\\v = \frac{2 \pi \times 3.5}{4.5} \\\\v = 4.89 \ m/s

Therefore, the tangential velocity of the student is 4.89 m/s.

When a particle vibrates and passes to the next vibration what happens?
kaheart [24]
Im not sure how detailed your answer is supposed to be but here it is: The particle that vibrates contains energy. That exact amount of energy is passed on to the next particle. This occurs because as you must know, energy is neither created nor destroyed. The same amount of energy contained in the vibration is simply passed on.

The correct option is A. the isobaric process represented by the PV diagram

<h3>What is  isobaric process?</h3>
  • An Isobaric method is a thermodynamic revolution taking place at consistent pressure. The period isobaric has been derived from the Greek words “iso” and “baros” indicating equal intimidation.
  • As such, the continued pressure is obtained when the importance is expanded or acquired. This basically neutralizes any pressure change due to the transfer of heat.
  • In an isobaric procedure, when the heat is transferred to the system some work is done. Nevertheless, there is even a change in the internal energy of the system.
  • This additionally means that no amounts as in the first law of thermodynamics evolve zero.

A single loop of wire with an area of 0.0920 m2 is in a uniform magnetic field that has an initial value of 3.80 T, is perpendic
jekas [21]

Answer:

Induced emf in the loop is 0.02208 volt.

Induced current in the loop is 0.0368 A.

Explanation:

Given that,

Area of the single loop, A=0.092\ m^2

The initial value of uniform magnetic field, B = 3.8 T

The magnetic field is decreasing at a constant rate, \dfrac{dB}{dt}=0.24\ T/s

(a) The induced emf in the loop is given by the rate of change of magnetic flux.

\epsilon=\dfrac{-d\phi}{dt}\\\\\epsilon=A\times \dfrac{dB}{dt}\\\\\epsilon=0.092\times 0.24\\\\\epsilon=0.02208\ V

(b) Resistance of the loop is 0.6 ohms. Let I is the current induced in the loop. Using Ohm's law :

\epsilon=IR\\\\I=\dfrac{\epsilon}{R}\\\\I=\dfrac{0.02208}{0.6}\\\\I=0.0368\ A

Hence, this is the required solution.

What is the difference between em waves and mechanical waves?
Anastaziya [24]

Answer:

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

Explanation:

Since electromagnetic waves do not require a medium to pass through, they are faster in matter that has fewer particles. ... ~ Sound cannot travel in a vacuum because mechanical waves, such as sound waves, require a medium to propagate through.
