Solnce55 [7]3 years ago
7 0

Explanation:

To me, it's option 1

Newton third law states that Every action produces an equal and opposite reaction. Hence, given the fact that the engine is on, it should be producing a constant force every time so, the speed should be constant as the force propelling it is the same

The magnetic field on the sun is created by _____.a liquid iron coreflowing charged plasmafrictioniron in the solar wind
Reptile [31]

The magnetic field on the sun is created by <u>flowing charged plasma</u> a liquid iron core flowing charged plasma friction iron in the solar wind.

Plasma, a gas-like state of matter in which electrons and ions have separated to produce a very hot mixture of charged particles, makes up the sun. Magnetic fields are naturally produced as charged particles move, and these fields have an additional impact on the motion of the particles.

Because the magnetic fields above the surface of the sun direct the travel of that plasma and cause the loops and towers of material in the corona to shine brilliantly in EUV photos, we can see the shape of the magnetic fields there.

A string of length 0.67 m and mass 2.0 g is held at both ends under tension. The string
ikadub [295]

Answer:

The value is \lambda = 0.335 \  m  

Explanation:

From the question we are told that

     The length of the string is  l  =  0.67 \  m

      The mass is  m  = 2.0 \  g  =  0.002 \  kg

      The frequency produced at  fourth harmonic vibration(i.e n =4 )  is  f =  700 \  Hz

  Generally the wavelength of the string is  mathematically represented as

            \lambda = \frac{ 2L }{n }

=>          \lambda = \frac{ 2 * 0.67 }{ 4 }  

=>          \lambda = 0.335 \  m
