So mathematical harmonics are based around a divergent set of fractions. Sigma(1/n)
with the 1st harmonic being... well 1, or 1 full wavelength.The second harmonic is exactly 1/2 the wavelength of the 1st with the third being 1/3 the wavelength. As Wavelengths go down, frequencies go up in a perfect ratio.

Second Harmonic has double the Frequency of the 1st or base note. Third Harmonic is triple and so on.

So the Harmonic set of 375 is.
1. 375
2. 375×2=750
3. 375×3= 1125

QveST [7]

We have thatThe options that define Speed, Velocity,Acceleration.

  • Speed is used to describe how fast the object is moving.
  • Acceleration is the rate of change of velocity in time.
  • Velocity is used to describe how fast the object is moving and tells us in which direction it is going.

Options

B,D,E

From the question we are told

Choose the correct definitions of speed, velocity, and acceleration. Check all that apply.

  • Acceleration tells us in which direction the object is going. Speed is the rate of change of velocity in time.
  • Acceleration is the rate of change of velocity in time.
  • Velocity is used to describe changes in the movement direction of the object. Acceleration tells us how far the object will go in a certain amount of time.
  • Velocity is used to describe how fast the object is moving and tells us in which direction it is going.
  • Speed is used to describe how fast the object is moving.
  • Velocity is the rate of change of speed in time.

Speed is used to describe how fast the object is moving and tells us in which direction it is going.

Generally

  • Acceleration is the rate of change of velocity in time.
  • Velocity is used to describe how fast the object is moving and tells us in which direction it is going.
  • Speed is used to describe how fast the object is moving without its direction in consideration

Hence

The options that define Speed, Velocity,Acceleration.

  • Speed is used to describe how fast the object is moving.
  • Acceleration is the rate of change of velocity in time.
  • Velocity is used to describe how fast the object is moving and tells us in which direction it is going.

Options

B,D,E

A loop of current-carrying wire has a magnetic dipole moment of 5. 0 10–4 am2. if the dipole moment makes an angle of 57° with a
Digiron [165]

The potential energy will be 1.46*10^-4J.

To find the answer, we have to know about the torque acting on a current loop in a uniform magnetic field.

<h3>How to find the potential energy of the loop?</h3>
  • We have the expression for torque acting on a current loop in a uniform magnetic field as,

                         \tau=MBsin\theta

where; M is the magnetic dipole moment, B is the magnetic field , and theta is the angle between M and B.

  • As we know that, the torque is equal to force times the perpendicular distance. Thus, it is equivalent to the work done. This work is stored as the potential energy in the loop.
  • Thus, the potential energy will be,

            \tau=W=U=MBsin\theta=5*10^{-4}*0.35*sin57=1.46*10^{-4}J

Thus, we can conclude that, the potential energy will be 1.46*10^-4J.

For a constant voltage, how is the resistance related to the current?
Aleksandr-060686 [28]

Answer:

Resistance is inversely proportional to current, so when the resistance doubles, the current is cut in half. Resistance is directly proportional to current, so when the resistance doubles, the current is cut in half.
