Answer:

A magnet is demagnetized. There is a decrease in chemical potential energy. There is an increase in thermal energy. And there is an increase in energy in the form of demagnetization.

What is the Einstein Rosen Bridge Theory? Is it possible why or why not? (IN YOUR OWN WORDS ANYTHING ELSE WILL BE DELETED)

kotegsom [21]

That states that the blackhole ends are working like bridges between one space to another.

And you can travel through them in 5-10s
The distance is thousands of lightyears but we can travel it..

This may be possible

A car speeds up from 3 m/s to 10 m/s in 8 s. How far does the car travel while doing this? 2. A

yarga [219]

Initial velocity=u=3m/s

Final velocity=v=10m/s

Time=t=8s

$\boxed{\sf Acceleration=\dfrac{v-u}{t}}$

$\\ \sf\longmapsto Acceleration=\dfrac{10-3}{8}$

$\\ \sf\longmapsto Acceleration=\dfrac{7}{8}$

$\\ \sf\longmapsto Acceleration=0.8m/s^2$

Distance =s

Using second equation of motion

$\\ \sf\longmapsto s=ut+\dfrac{1}{2}at^2$

$\\ \sf\longmapsto s=3(8)+\dfrac{1}{2}(0.8)(8)^2$

$\\ \sf\longmapsto s=24+0.4(64)$

$\\ \sf\longmapsto s=24+25.6$

$\\ \sf\longmapsto s=49.6m$

What is the acceleration of the 698 kg car that experiences a force of 2410 N?

Nostrana [21]

Hey there!

If you're working with Newton's Laws / Acceleration, the formula would mostly like look like this

$F= MA$ or you could say → $A = \frac{F}{M}$

While the $F$ variable represents $net$ $forces$ of your car and the $m$ represents the mass of the car $mass$

Denominator: $2,410$

Numerator: $698$

Your equation: $\frac{2410}{698}$ ( if you simplify that ←) then you have found your result!

$Answer: \boxed{C) 3.45 m/s^2}$

Good luck on your assignment and enjoy your day!
