How did the ideas of einstein and freud contribute to a sense of uncertainty?
Ipatiy [6.2K]
Einstein's Theory of Relativity was a theory which carried about hesitation in Newton's gravity which was measured as an important part of science. Which brings one to query what we detect as being factual. 
Freud's thoughts about the subliminal questions one's own mind to what we have faith in. Is a dream just a dream, or is it your subliminal trying to tell you a little? It brought about a feeling of being ignorant of what is going on in your own mind. 
These and maybe other bring persons to doubt about the world about them and within themselves.

A free electron is moving with a velocity of 3 × 105 m/s. It strikes a stationary electron in a head-on elastic collision. The m
Gelneren [198K]

Answer:

After the colision, the stationary electron's momentum is given as:

P = 2.7328 x 10^(-25) kg m/s

The direction of momentum is the same as the direction of velocity of the electron.

Explanation:

In an Isolated system, when an object moving at some velocity v collides head on with a stationary object of equal mass. There velocities are exchanged.

This means that the first electron will become stationary and the electron which was stationary initially will start moving at a velocity of 3*10^(5)m/s in the same direction as the first electron.

Post collision momentum of the stationary electron:

V = 3 x 10^5 m/s

m = 9.1093 x 10^(-31) kg

Momentum = P = mV =  9.1093 x 10^(-31) x 3 x 10^5

P = 2.7328 x 10^(-25) kg m/s

The direction of momentum is the same as the velocity of the electron.

PLSSS HELPPPPP!! due today @ 8:30!
romanna [79]

Answer:

(1) weight = 565N

distance = 325m

time= 12.6s

power = work done/time

work done= force * distance

= 565*3.25 =1836.25

:. power = 1836.25\12.6

=145.7!

(2) the books will add more to her weight and thereby increasing her power output.
