Answer:

<h2><em><u>solar wind</u></em></h2>

Explanation:

<em>This stream of particles emanating from sun's magnetic field is known as the solar wind. </em>

<em>The gas and particles come from the Sun's hot outer atmosphere, called the corona. These particles from the corona are charged with electricity.</em>

What travels by vibrating particles? Mechincal Waves or ElecrtoMagnetic Waves.

Naddik [55]

Answer:mechanical waves.

Explanation:

Mechanical waves require the particles of the medium to vibrate in order for energy to be transferred. For example, water waves, earthquake/seismic waves, sound waves, and the waves that travel down a rope or spring are also mechanical waves.

A student standing on a stationary skateboard tosses a textbook with a mass of mb = 1.25 kg to a friend standing in front of him

juin [17]

Answer:

The velocity of the student has after throwing the book is 0.0345 m/s.

Explanation:

Given that,

Mass of book =1.25 kg

Combined mass = 112 kg

Velocity of book = 3.61 m/s

Angle = 31°

We need to calculate the magnitude of the velocity of the student has after throwing the book

Using conservation of momentum along horizontal direction

$m_{b}v_{b}\cos\theta= m_{c}v_{c}$

$v_{s}=\dfrac{m_{b}v_{b}\cos\theta}{m_{c}}$

Put the value into the formula

$v_{c}=\dfrac{1.25\times3.61\times\cos31}{112}$

$v_{c}=0.0345\ m/s$

Hence, The velocity of the student has after throwing the book is 0.0345 m/s.

In order for an object to have kinetic energy it must have a mass and a ?

almond37 [142]

Answer:

Velocity

Explanation:

The mechanical energy of the body is defined as the sum of the potential energy and kinetic energy.

E = P.E + K.E

The potential energy of a body is due to the height from the surface of the earth.

P.E = mgh

The kinetic energy of the is possessed by the body due to the virtue of its motion,

K.E = ½ mv²

If there is no velocity associated with the body, there is no K.E in the body.
