Answer:
Well,
Explanation:
In a wave, energy is transported without the transport of water. Basically, a wave can be described as a disturbance that travels through a medium, transporting energy from one location to another location without transporting matter.
Answer:
The superball cannot rebound to a higher height than its original height because that would go against the laws of energy conservation. For it to bounce higher than its original height, that means the potential energy acting on it is higher than the one it had been dropped with originally, and that energy must be an external one. However, it should be noted that if the superball is thrown downwards with an extra energy, then it can rebound higher than the original height.
Explanation:
Sensory nerves detect senses like touch, see, smell stuff like that. Motor nerves gives the reaction from the brain after receiving the information from the sensory nerves. example of when you touch a hot water your sensory nerves brings the information and your react to by pulling your hand out of the water. hope it helps

"<span>A small glass bead has been charged to + 25 nC "
Solution
The force exerted on a charge q by an electric field E is given by
</span>
<span>Considering the charge on the bead as a single point charge, the electric field generated by it is
</span>
with
,
is the charge on the bead. We want to calculate the field at
:
The proton has a charge of
, therefore the force exerted on it is
And finally, we can use Newton's second law to calculate the acceleration of the proton. Given the proton mass,
, we have
The charge on the bead is positive, and the proton charge is positive as well, therefore the proton is pushed away from the bead, so:
Answer:
Explanation:
Writing Newton's 2nd Law and Newton's Gravitational Law on the satellite (of mass <em>m,</em> experimenting an acceleration <em>a)</em> orbiting Earth (of mass <em>M</em>) with <em>r</em> as the distance between their centers we have:
Since this acceleration is centripetal, we can write:
So we have:
Or:
This distance <em>r</em> is the sum of Earth's radius <em>R</em> and the satellite's altitude <em>h </em>(<em>r=R+h</em>), so for our values we have (in S.I.):
