What are the two requirements of a circuit so that current will flow?
antoniya [11.8K]

Answer:

-The battery-the power source

-Closed conducting loop

Explanation:

-To produce an electric current, the following requirements must be met:

-A battery-This is the energy source than will do work on the charge thus moving from a low energy location to high energy location.

-Closed Conducting Loop-The loop is usually made of copper wires due to their high electric conductivity.

To what tension (in newtons) must you adjust the screw so that a transverse wave of wavelength 3.33 cm makes 621 vibrations per
PilotLPTM [1.2K]

Answer:

T=9.4 N

Explanation:

We are given that

Mass of wire,m=16.5 g=\frac{16.5}{1000}kg

1 kg=1000g

Length of wire,l=75 cm=75\times 10^{-2}m

1 m=100 cm

Wavelength of transverse wave=\lambda=3.33 cm=3.33\times 10^{-2}m

Frequency=621 Hz

Mass per unit length=m_l=\frac{m}{l}=\frac{16.5}{1000\times 75\times 10^{-2}}=0.022 kg/m

\nu=\frac{v}{\lambda}

v=\nu \lambda

Where\nu=frequency of wave

\lambda=Wavelength of wave

Speed of wave=v

Using the formula

v=3.33\times 10^{-2}\times 621=20.7m/s

v=\sqrt{\frac{T}{m_l}}

v^2=\frac{T}{m_l}

T=v^2m_l

Using the formula

T=(20.7)^2\times 0.022=9.4N

Hence, the tension,T=9.4 N

Explain in terms of the arrangementbof particles the kinetic theory of matter​
baherus [9]

Answer:

Matter is made up of particles that are constantly moving. All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state.
