Answer:
<h2>8.0995×10^-21 kgms^-1</h2>
Explanation:
Mass of proton :

Speed of Proton:

Linear Momentum of a particle having mass (m) and velocity (v) :

Magnitude of momentum :

Frome equation (2), magnitude of linear momentum of the proton :

<span>C.
Sample C would be best, because the percentage of the energy
in an
incident wave that remains in a reflected wave from this material
is the
smallest.
The coefficient of absorption is the percentage of incident sound
that's absorbed. So the highest coefficient of absorption results in
the smallest </span><span>percentage of the energy in an
incident wave that remains.
That's what you want. </span>
Answer:
Hey!
Your answer should be D!
Explanation:
In a transformer Np / Ns is called the voltage ratio. If Ns is less than Np then Vs is less than Vp. This is called a step-down transformer as the voltage is reduced.

The question extends beyond what I already know.
The question makes me curious.
Answer:
The primary effects of earthquakes are ground shaking, ground rupture, landslides, tsunamis, and liquefaction. Fires are probably the single most important secondary effect of earthquakes.
