The correct answer to the question is : A) Sound waves.

EXPLANATION:

Before going to answer this question, first we have to understand sound wave.

A sound wave is a longitudinal wave which needs a medium for its propagation. It moves in the form of compression and rarefaction in a medium. The medium may be solid,liquid or gases.

Unlike sound waves, gamma waves, micro waves and UV waves do not require any medium for its propagation. They can travel in space also. They all are included in electromagnetic series.

Hence, the correct answer to the question is Sound waves.

In the model of the hydrogen atom due to Niels Bohr, the electron moves around the proton at a speed of 3.3 × 106 m/s in a circl

irga5000 [103]

Answer:

$1.5048\times 10^{-23}\ Am^2$

Explanation:

q = Charge of proton = $1.6\times 10^{-19}\ C$

r = Radius of circle = $5.7\times 10^{-11}\ m$

v = Velocity of proton = $3.3\times 10^6\ m/s$

Magnetic moment is given by

$M=\frac{1}{2}qrv\\\Rightarrow M=\frac{1}{2}1.6\times 10^{-19}\times 5.7\times 10^{-11}\times 3.3\times 10^6\\\Rightarrow M=1.5048\times 10^{-23}\ Am^2$

The magnetic moment associated with this motion is $1.5048\times 10^{-23}\ Am^2$

A hockey puck wont slide very far on concrete or asphalt, but it will slide for a very long time on ice. Why is this?

Ilya [14]

When hockey players push the puck along the ice it slides causing heat which melts the ice causing the friction against the ice to be less.

If an object undergoes a change in momentum of 10 kg m/s in 3 s ,then the force acting on it is

Paha777 [63]

Answer:

Force = 3.333 Newton

Explanation:

Given the following data;

Change in momentum = 10 Kgm/s

Time = 3 seconds

To find the force acting on it;

In Physics, the change in momentum of a physical object is equal to the impulse experienced by the physical object.

Mathematically, it is given by the formula;

Force * time = mass * change in velocity

Impulse = force * time

Substituting into the formula, we have;

10 = force * 3

Force = 10/3

Force = 3.333 Newton
