Pump is one of the two main parts of hydraulic system. ( the other one is the engine)

the input force in this system is caused by the engine to make the pump work and the output is made up by pump by pushing the liquid in the hydraulic system.

If radio waves were used to communicate with an alien spaceship approaching Earth at 10% of the speed of light c, Earth would re
klemol [59]

Answer:

Explanation:

speed of alien spaceship = .1 c

We shall apply formula of relativistic mechanics to solve the problem

relative velocity =

\frac{v+v_1}{1 -\frac{v\times v }{c^2} }

Here v = v₁ = .1 c

relative velocity  = .1c + .1 c / 1 - .1²

= .2 c / .99

= .202 c

The earth would receive the signal at the speed of .202 c .

An electron and a proton are each placed at rest in a uniform electric field of magnitude 560 N/C. Calculate the speed of each p
Butoxors [25]

Answer:

The speed of electron is v=4.52\times 10^6\ m/s and the speed of proton is 2468.02 m/s.

Explanation:

Given that,

Electric field, E = 560 N/C

To find,

The speed of each particle  (electrons and proton) 46.0 ns after being released.

Solution,

For electron,

The electric force is given by :

F=qE

F=1.6\times 10^{-19}\times 560=8.96\times 10^{-17}\ N

Let v is the speed of electron. It can be calculated using first equation of motion as :

v=u+at

u = 0 (at rest)

v=\dfrac{F}{m}t

v=\dfrac{8.96\times 10^{-17}}{9.1\times 10^{-31}}\times 46\times 10^{-9}

v=4.52\times 10^6\ m/s

For proton,

The electric force is given by :

F=qE

F=1.6\times 10^{-19}\times 560=8.96\times 10^{-17}\ N

Let v is the speed of electron. It can be calculated using first equation of motion as :

v=u+at

u = 0 (at rest)

v=\dfrac{F}{m}t

v=\dfrac{8.96\times 10^{-17}}{1.67\times 10^{-27}}\times 46\times 10^{-9}

v=2468.02\ m/s

So, the speed of electron is v=4.52\times 10^6\ m/s and the speed of proton is 2468.02 m/s. Therefore, this is the required solution.
