Why is electricity dead buy solar panels fundamentally different from converting thermal energy into electricity? (Bet you can't

get this one)

Because solar panels are man made so they can shut down, not move, break, etc...? Don’t judge me, it’s just a guess.

Un hamster esta sentado sobre un tocadisco cuya rapidez angular es constante si el hamster se mueve a un punto localizado al dob

kotegsom [21]

Answer:

b) se duplica

Explanation:

The disk is moving with constant angular velocity, let's call it $\omega$ .

The linear velocity of a point on the disk is given by

$v=\omega r$

where r is the distance of the point from the axis of rotation.

In this problem, the object is moved at a distance twice as far as the initial point, so

$r' = 2r$

Therefore, the new linear velocity is

$v'=\omega r' = \omega (2r) = 2 \omega r = 2 v$

So, the velocity has doubled, and the correct answer is

b) se duplica

Assuming no friction form air, how far will a dropped rock fall in 10 seconds

serious [3.7K]

<u>Given that</u>

time (t) = 10 s ,

(S) = ?

We know that S = ut+ 1/2 a.t² m

since free fall and no air friction,

a = g = 9.81 m/s² ; initial velocity u= 0

S = 0 + [1/2 × 9.81 ×10²]

<em> S = 490.5 m </em>

How is artificial gravity created in spaceships and sattelites ?????? U need some IQ for this

goldfiish [28.3K]

Explanation:

Artificial gravity can be created using a centripetal force. A centripetal force directed towards the center of the turn is required for any object to move in a circular path. In the context of a rotating space station it is the normal force provided by the spacecraft's hull that acts as centripetal force.

Hope it helps.
